DeviceActivityMonitor intervalDidEnd not firing for non-repeating timed unlock
I’m building an iOS app that uses FamilyControls + ManagedSettings + DeviceActivity. Goal: temporarily “unlock” a shielded app for N minutes, then automatically re-apply the shield when the timer expires. What I do: In the main app, when user picks an expiry (e.g. 15 min, 30 min). I start a non-repeating DeviceActivity schedule and remove the app’s ApplicationToken from ManagedSettingsStore().shield.applications. I also store activeUnlockBundleID etc. in an App Group so the DeviceActivityMonitor extension can re-lock at the end. Expected: DeviceActivityMonitor.intervalDidEnd(for:) is invoked when the non-repeating interval ends, and I re-add the token to the shield set. Actual: The app does not re-lock when the interval expires. I added OS logs as well as “debug local notifications” from the DeviceActivityMonitor extension in: init() intervalDidStart intervalDidEnd eventDidReachThreshold None of these logs or notifications ever appear, which suggests the extension is never invoked (or cannot schedule local notifications or OS logs). Environment: Device: iPhone 17 Pro iOS 26.3.1 Xcode 26.4 Running on a physical device Notification permissions for the app: granted App + extensions are in the same App Group entitlement. Extension Info.plist has: NSExtensionPointIdentifier = com.apple.deviceactivity.monitor NSExtensionPrincipalClass = $(PRODUCT_MODULE_NAME).DeviceActivityMonitorExtension Questions: Are there known limitations/requirements for DeviceActivityMonitor callbacks where intervalDidEnd doesn't to fire? Is posting local notifications / OS Logs from a DeviceActivityMonitor extension supported/reliable? If not, what’s the recommended way to verify the extension is invoked? If this looks like a platform bug, should I file Feedback Assistant? If so, what logs/artifacts are most useful?

AlarmKit alarm occasionally fires at exactly 12:00 AM
[FB22327481] We are observing a rare issue where alarms scheduled using AlarmKit occasionally fire exactly at 12:00 AM, even though the alarm was scheduled for a different time. This issue happens only for a very small number of users (for example, 1–2 users per several thousand per day), but multiple reports confirm that the alarm goes off exactly at midnight. We also found that other developers are experiencing the same issue: https://aninterestingwebsite.com/forums/thread/815714 Observed behavior For a small number of users: Alarm fires at exactly 00:00 (midnight) This happens even when the scheduled alarm time is something like 7:30 AM Happens rarely Hard to reproduce internally Appears to happen only on real devices in production Additional notes We are using AlarmKit fixed schedules (not relative) Dates passed to AlarmKit are correct at scheduling time We do not intentionally create midnight alarms Issue seems random Question Are there any known limitations or edge cases with AlarmKit fixed schedules that could cause alarms to fire at midnight? For example: Invalid date fallback? Schedule expiration fallback? Time zone changes? Background refresh timing? Maximum schedule window? Any guidance would be appreciated, as this is affecting real users but is difficult to reproduce.

DeviceActivityMonitor extension intervalDidStart never called on iOS 26.3.1
On iOS 26.3.1, deviceactivityd produces zero log output and never wakes a DeviceActivityMonitor extension at the scheduled time, even when the schedule is successfully registered. The extension's intervalDidStart(for:) method is never called. Steps to Reproduce: Create an app with a DeviceActivityMonitor extension subclass Add the com.apple.developer.family-controls entitlement to both the main app and extension targets Add a shared App Group entitlement to both targets In the main app, call: let center = DeviceActivityCenter() center.stopMonitoring([.myActivity]) let schedule = DeviceActivitySchedule( intervalStart: DateComponents(hour: 17, minute: 30), intervalEnd: DateComponents(hour: 17, minute: 45), repeats: true ) try center.startMonitoring(.myActivity, during: schedule) Verify registration succeeds: DeviceActivityCenter().activities.contains(.myActivity) returns true Background the app completely and wait for the intervalStart time (5:30 PM in this example) Expected Result: intervalDidStart(for:) is called in the extension process at 5:30 PM. ManagedSettings shields are applied without any user interaction. Actual Result: intervalDidStart(for:) is never called. No extension process is launched. Filtering Console.app for deviceactivityd on the device returns 0 messages — the daemon produces no logs whatsoever despite an active registered schedule. Shields are never applied. Additional Evidence: Third-party apps using DeviceActivity (e.g. Prayer Lock) successfully apply shields at scheduled times on the same device and OS version, confirming the framework is not universally broken Filtering Console.app for the app's bundle ID at the trigger time shows the main app process applying shields via a UNCalendarNotificationTrigger fallback — but no extension process activity DeviceActivityCenter().activities correctly lists the registered activity before and after the trigger time, confirming the schedule registration API is functional Environment: iOS 26.3.1 Physical device (required for FamilyControls) Development-signed build with com.apple.developer.family-controls entitlement provisioned App Group shared between main app and extension targets

Compensating for IMU (accelerometer) thermal drift - getting device temperature?
I’m running into a hardware reality. MEMS sensor thermal drift. If a user zeroes out the tilt indoors at 20°C and then takes the phone outside in the cold, the accelerometer baseline shifts just enough as the device cools to throw off the readings. I want to apply a simple thermal compensation curve to the CoreMotion data to keep the "zero" perfectly level regardless of the weather. However, ProcessInfo.thermalState only gives broad buckets (nominal, fair, etc.) which doesn't help me calculate a continuous offset for a phone cooling down degree by degree. Is there any public API, or even a proxy metric, that can give me a rough battery or internal temperature integer? I don’t need high resolution decimals. Just a general device temp to offset the hardware drift. Any undocumented tricks or proxy metrics anyone has used to handle this?

Custom icons for folder aliases not showing
Problem: custom icons for folder aliases not showing System drive and external drive custom alias folder icons don't showup on desktop or external drive (OS14.6 Sonoma 2023); they only show-up as plain folders or with an odd document icon. Alias doesn't connect to image; however it's there, easily accessible via spacebar. Finder doesn't save the custom icon to the alias. See below for workaround. Summary: I have custom alias icons on my desktop linking to their source files on the system drive and external drive.. however they do not display the custom icon. After upgrading from OS10.14 Mojave to OS14.6 Sonoma 2023, system drive & external drive custom alias icons no longer display the icon on either drive (there is a work-around for Mojave; see history section). Personal impact: hampered file navigation and workflow; I'm lost, can't tell where anything is; not having my icons makes it especially difficult to navigate my files and hampers my workflow significantly. Desired outcome: all custom icons for folder aliases linking to source files (on system & external drives) appear on the desktop, and in all directories on system & external drives (including encrypted external drives). Status.. August 2024: called apple support, they said there is no solution, and there are no plans to fix it, and no plans for a fix in OS 15 Sequoia (in public beta now) Action: ❯ leave feedback at https://www.apple.com/feedback/macos/ ❯ join this campaign to fix this once and for all! -- After 20 years of dealing with this issue.. we need to fix this. History: ▪ OS 10.14 Mojave 2018: external drive alias icons don't work; because upon startup, the icon images for these files disappear; because when system starts it loads the system drive icons but not the external drive icons because it's password protected, hence icon information does not get loaded; alias icons can't connect with unmounted external drive @ boot; however it's there, easily accessible via spacebar the FIX: alias the icons on the desktop each time after boot, however the names are altered ▪ OS X 10.11 El Cap 2015: drag the icons to a folder then back to desktop.. sometimes this works I stayed on OS9 as long as possible because of the OS10 icon problem ▪ OS 9: all custom alias folder icons worked fine Givens: space bar has fast access to icon -highlight alias and press space bar -- seems that it would be a simple solution, since the image is there -- get info for alias also has the image in preview How to make a custom icon: open a pic (typically from a screenshot; .png), select image with cursor with shift key down (for a perfect square), copy ⌘C, click target folder, get info ⌘I, click on folder icon on top left corner, paste ⌘V Fix -- How? --make a solution approach for a macOS dev? some bash process to link to icon; how to access icon Swift? process to renew the alias icon process goes through all desktop icons.. fixes them; new icon, correct name routine where all icons on desktop link to their files easily making a new alias.. as easy as making a regular alias; cammand L, etc make alias search for the image app that makes alias create custom desktop.. a GUI w links -- INTERIM FIX / WORKAROUND create a new folder on your desktop, name it, place it's alias inside the folder, fix the icon, when you open the desktop folder, you will then have to click on the alias --this is very time-consuming and tedious note: there may be easier options for OSs prior to Sonoma; review History section workflow: symbol note: ⇧ shift, ⌃ control, ⌥ option, ⌘ cammand create new folder on desktop ⌘⇧N , name it.. if the name is already taken by the alias, change the alias's name; for example.. alias it ⌘^A click on this new folder then ⌘I (get info) click on the alias, open source location ⌘R (or ⌘⌥^A on older OSs), click on source file (if not highlighted) then ⌘I (get info) , click on folder icon on top left corner, copy ⌘C click on the get-info window you opened for the new folder, click on folder icon on top left corner, paste ⌘V (if not working see ¹ below), close each of these windows with ⌘W place the associated aliased folder into the new folder you can also do this in groups of folders (3-6 seems is optimal).. for example.. move 3 alias icons to clear area on desktop, create 3 new folders and place them below the aliases, select all aliases and ⌘C, open a text document and ⌘V, fix names & name new folders, select new folders, ⌘I, select target aliases, ⌘R, ⌘I for each, move the alias windows below the new folder windows, copy/paste icons from source to new file, close these windows, place alias folders into new folders ¹ if paste function not working.. move on to the next folder and come back.. it can be moody, if it's not working at all.. restart the computer note2: some icons now have a yellow streak at the bottom let us know if you have any solutions or workarounds, or can code this (provide a script or app)

Cellular not initializing on iPadOS 26.4 (resolved by network reset)
We are seeing an issue after updating iPads to iPadOS 26.4 where cellular service is lost until network settings are reset. Environment: Devices managed via Apple Business Manager and Microsoft Intune Carrier: Verizon Confirmed affected devices: iPad (9th generation) eSIM Behavior: After update, device shows no cellular service No prompt to re-activate or re-add the cellular plan The plan appears to still be present on the device Workaround observed: Resetting Network Settings restores service Notes: This does not appear to be a provisioning issue (no need to re-add eSIM) Behavior suggests the cellular/eSIM state may not be initializing correctly after update Toggling Cellular or Airplane mode has not yet been tested for service restoration. We have not yet confirmed whether devices using a physical SIM are affected Still gathering data on scope across additional iPad models Additional observation: We have not observed this behavior on iPhones (e.g., iPhone 16 on iOS 26.4 with LTE remains unaffected) Has anyone else observed similar behavior on iPadOS 26.4, particularly on managed devices or eSIM configurations?

Updating widgets using using Tunnel.appEx
Hi, i searched some information about how widgetKit updates widgets using "reloadAllTimelines/reloadAllControls" and i know about daily limit for apps to update their widgets. I only care about how to notify user instantly about vpn status change even if app is terminated and user launch vpn connection from ControlCenter(system widget) or SysSettings, is there a way to update my app's contolCenter widgets from Tunnel if widget and tunnel extensions already have same appGroup defaults?

Transaction.currentEntitlements sometimes does not emit a result until device is reboot
I have the typical StoreKit 2 manager class, where I check currentEntitlements for subscription. I have filed a feedback (FB22349195), I hope someone can take a look at it. func updateCustomerProductStatus() async { var activeSubscription: String? = nil // BUG: In some cases the currentEntitlements does not emit a transaction until the device is reboot for await result in Transaction.currentEntitlements { print("Found transaction: \(result)") // This print does not appear until a restart! do { let transaction = try checkVerified(result) // Skip revoked transactions if transaction.revocationDate != nil { print("Skipping revoked transaction for \(transaction.productID)") continue } // Skip expired subscriptions if let expirationDate = transaction.expirationDate, expirationDate < Date() { print("Skipping expired subscription for \(transaction.productID)") continue } // Check product type switch transaction.productType { case .autoRenewable: activeSubscription = transaction.productID default: break } } catch { print("Unable to verify transaction: \(error)") } } // Update state once after processing all entitlements self.activeSubscription = activeSubscription print("updateCustomerProductStatus() activeSubscription: \(activeSubscription ?? "nil")") } There is some unexpected behavior where the currentEntitlements does not emit a result until the iPhone device is reboot. This bug appeared in iOS 26.4 (and in the betas).

Family controls distribution request (timeline info)
Hello, I submitted a request for the Family Controls (Distribution) entitlement, but haven't received status update regarding approval/rejection etc. I submitted a previous contact support ticket as well. I'm wondering the timeline and also if my request went through - currently it says 'submitted' but it's remained this way for a while... I've had other developers in communities saying they were approved earlier, so curious if it's an app issue. Thank you

NETransparentProxyProvider stops intercepting flows after sleep/wake cycle on macOS intermittently
I am seeing an issue with NETransparentProxyProvider where the extension successfully transitions from sleep to wake, but stops receiving handleNewFlow(_:) calls. Only below two methods gets called, We don't apply rules in these methods: override func wake() override func sleep(completionHandler: @escaping () -> Void) This breaking complete proxy workflow as it stops intercepting traffics. We are not observing this issues always. FYI: com.apple.developer.endpoint-security.client is not present in .entitlement file. I am not sure adding this will help. Any possibilities nesessionmanager might fail to re-bind the traffic rules for this extensions? Any thing we can do to avoid this issues?

Memory Leak in new structured concurrency Network Framework API's
After implementing the new structured concurrency API's for Network framework, we are noticing a few memory leaks in the Network framework when using API's like onViabilityUpdate and onBetterPathUpdate. Whenever a previously established connection is disconnected, the NWConnection object is never released by the Network framework when we use the 2 API's mentioned. Irrespective of what goes inside these handlers(or leave it empty), the connection object is leaking. If I comment out the handlers, there is no memory leak. Posting this here in the forum to understand if others have encountered similar issues and found a workaround? Raised a feedback assistant request with all the details and a sample app here: FB22339653

Allow to open parent app from ShieldActionDelegate: `ShieldActionResponse.openParentApp`
Hello, I am the developer of an app called one sec which helps users to spend less time on social media: https://one-sec.app Therefore, we make heavy use of the Screen Time API, and thus ManagedSettings and ShieldActionDelegate. One feature of one sec is the so-called “Doom Scroll Emergency Brake”. This blocks a target app after a certain usage threshold (e.g. 5 minutes) and requires going through an intervention (e.g. breathing exercise) to unlock more time. That added friction makes it very effective in reducing time spent on apps. One thing that is confusing for our users is the way they are prompted to unlock more time, if they want to. They have to: Have Push Notifications enabled for one sec Exempt one sec’s notifications from being delayed by AI prioritization (otherwise they are delayed by ca. 10s) Ensure that push notifications can be delivered during foci. Understand that they have to tap on the notification, which is not very straight-forward because it does not make sense from the user’s UX perspective. This is an artificial limitation of Apple’s screen time framework which has no reason (no security / privacy implications here…). Screenshots of the current flow attached. If would be much more reasonable if there was a new ShieldActionResponse.openParentApp value that can be returned from the completion handler of the ShieldActionDelegate.handle(…) callback. We have seen different apps use private API to achieve this, but we are afraid to do the same to avoid getting banned from the App Store. It would be fair if Apple would level the playground for all apps and offer such an API officially. – Frederik PS: Tracked under FB22347946, FB18846650, FB15500681, FB15079668, FB10393561 (all without responses so far…)

FamilyControls individual authorization: No way to detect revocation while app is backgrounded
We are developing an MDM agent app that uses FamilyControls with .individual authorization to enforce Screen Time restrictions (app blocking, domain blocking via ManagedSettingsStore and DeviceActivityCenter). The Problem We are actively subscribing to AuthorizationCenter.shared.$authorizationStatus to detect authorization changes. However, when the user revokes the app's FamilyControls authorization through Settings (either via Settings > Screen Time > Apps With Screen Time Access, or Settings > Apps > [Our App]), the publisher does not emit any value. All ManagedSettingsStore restrictions are lifted immediately by the system, but our app receives no notification of this change. The only scenario where the publisher reliably emits is when a debugger is attached (i.e., running directly from Xcode). Without the debugger, the publisher is completely silent — even when the app returns to foreground. Code Example We tried subscribing directly to AuthorizationCenter.shared.$authorizationStatus with no intermediary, exactly as shown in the documentation: AuthorizationCenter.shared.$authorizationStatus .sink { status in print("[DIRECT] authorizationStatus emitted: \(status)") } .store(in: &cancellables) This subscription is set up at app launch and stored in cancellables. The result is the same — the publisher does not emit when the user revokes authorization in Settings without a debugger attached. Documentation Reference The documentation for authorizationStatus states: "The status may change due to external events, such as a child graduating to an adult account, or a parent or guardian changing the status in Settings." And: "The system sets this property only after a call to requestAuthorization(for:) succeeds. It then updates the property until a call to revokeAuthorization(completionHandler:) succeeds or your app exits." This suggests the publisher should emit when the status is changed via Settings, but in our testing it does not — unless a debugger is attached. What We Verified We tested with a development-signed build (which includes the com.apple.developer.family-controls entitlement), launched from Xcode, then disconnected the debugger, killed the app, and relaunched from the home screen. Scenario Publisher emits on revocation? Running from Xcode (debugger attached) Yes, immediately Development-signed build (no debugger) No — silent even on foreground return We also confirmed: MDM configuration profiles can disable Screen Time entirely, but cannot restrict the per-app authorization toggle — the user can always freely revoke the app's Screen Time access The Security Gap This creates a significant gap for parental controls use cases: User leaves the app (app goes to background) User goes to Settings and disables Screen Time access for the app All restrictions are immediately lifted User uses the device freely User re-enables Screen Time access and opens the app Everything syncs back to normal — administrator never knows Questions Is there any supported mechanism to receive a notification (background or foreground) when FamilyControls individual authorization is revoked? We are subscribing to AuthorizationCenter.shared.$authorizationStatus but it does not emit. Is the $authorizationStatus publisher expected to work only when a debugger is attached? Is this a known limitation or a bug? Can DeviceActivityMonitor extension detect authorization revocation? Based on documentation it appears limited to schedule/threshold events, but we haven't confirmed this. Is there a planned API improvement to address this gap? Environment iOS 26.2 Xcode 26.3 Swift 6.2.4 FamilyControls .individual authorization Related Threads Screen time API can be disabled easily Changing Screen Time Passcode does not protect apps

swift: Calling "/usr/bin/defaults" returns no data
I'd like to create a small helper app for new students do read/write User default settings. Since it was not possible using the UserDefaults class I decided to use the "/usr/bin/defaults". Unfortuntely it seems not to return anything. Debug output shows "Got data: 0 bytes" Here is a sample code: import SwiftUI func readDefaults(domain : String, key :String) -> String { let cmdPath = "/usr/bin/defaults" //let cmdPath = "/bin/ls" let cmd = Process() let pipe = Pipe() cmd.standardOutput = pipe cmd.standardError = pipe cmd.executableURL = URL(fileURLWithPath: cmdPath, isDirectory: false, relativeTo: nil) cmd.arguments = ["read", domain, key] //cmd.arguments = ["/", "/Library"] print("Shell command: \(cmdPath) \(cmd.arguments?.joined(separator: " ") ?? "")") var d : Data? do { try cmd.run() d = pipe.fileHandleForReading.readDataToEndOfFile() cmd.waitUntilExit() } catch let e as NSError { return "ERROR \(e.code): \(e.localizedDescription)" } catch { return "ERROR: call failed!" } // get pipe output and write is to stdout guard let d else { return "ERROR: Can't get pipe output from command!" } print("Got data: \(d)") if let s = String(data: d, encoding: String.Encoding.utf8) { print("Got result: \(s)") return s } else { return "ERROR: No output from pipe." } } struct ContentView: View { let foo = readDefaults(domain: "com.apple.Finder", key: "ShowHardDrivesOnDesktop") var body: some View { VStack { Text("ShowHardDrivesOnDesktop: \(foo.description)") } .padding() } } #Preview { ContentView() } This code works well e.g. for "ls" when the comments are changed for cmdPath and cmd.arguments. What do I miss in order to get it working with defaults?

Xcode 26.4 breaks compilation: Sending 'activity' risks causing data races
After updating Xcode and SDK to 26.4, I'm now getting an concurrency error when trying to update or end live activities with the following code that built successfully before: // Get list of active activities let allActivities = Activity<ArbeitszeitWidgetAttributes>.activities // Cancel all active activities Task { for activity in allActivities { await activity.end(nil, dismissalPolicy: .immediate) } } Sending 'activity' risks causing data races. Sending main actor-isolated 'activity' to @concurrent instance method 'update' risks causing data races between @concurrent and main actor-isolated uses I'm currently using nonisolated(unsafe) let activity = activity await activity.end(nil, dismissalPolicy: .immediate) to get it to compile again. What's the best approach here?

Brazil Digital ECA Eligibility after the 26.4 Release
Hi, Regarding the Brazil Digital ECA (DECA) requirements, which became effective on March 17, 2026. Following the guidance for regulated regions, we have been testing the eligibility check with the iOS 26.4 release. We previously confirmed that isEligibleForAgeFeatures was returning true for users in the Brazil region, which allowed us to verify our age-gating implementation. A few questions follow on this eligibility check: We have observed in manual testing that specific devices which returned true as recently as March 23rd are now returning false today, despite no changes to the OS build or account settings. Does this indicate a change in the server-side eligibility heuristics? Why would isEligibleForAgeFeatures stop returning true for a region where the law is now in force? Has the guidance on how to evaluate these properties for Brazil changed with the transition to the stable 26.4 release? Thank you!

DeviceActivityMonitor intervalDidEnd not firing for non-repeating timed unlock

AlarmKit alarm occasionally fires at exactly 12:00 AM
[FB22327481] We are observing a rare issue where alarms scheduled using AlarmKit occasionally fire exactly at 12:00 AM, even though the alarm was scheduled for a different time. This issue happens only for a very small number of users (for example, 1–2 users per several thousand per day), but multiple reports confirm that the alarm goes off exactly at midnight. We also found that other developers are experiencing the same issue: https://aninterestingwebsite.com/forums/thread/815714 Observed behavior For a small number of users: Alarm fires at exactly 00:00 (midnight) This happens even when the scheduled alarm time is something like 7:30 AM Happens rarely Hard to reproduce internally Appears to happen only on real devices in production Additional notes We are using AlarmKit fixed schedules (not relative) Dates passed to AlarmKit are correct at scheduling time We do not intentionally create midnight alarms Issue seems random Question Are there any known limitations or edge cases with AlarmKit fixed schedules that could cause alarms to fire at midnight? For example: Invalid date fallback? Schedule expiration fallback? Time zone changes? Background refresh timing? Maximum schedule window? Any guidance would be appreciated, as this is affecting real users but is difficult to reproduce.

DeviceActivityMonitor extension intervalDidStart never called on iOS 26.3.1
On iOS 26.3.1, deviceactivityd produces zero log output and never wakes a DeviceActivityMonitor extension at the scheduled time, even when the schedule is successfully registered. The extension's intervalDidStart(for:) method is never called. Steps to Reproduce: Create an app with a DeviceActivityMonitor extension subclass Add the com.apple.developer.family-controls entitlement to both the main app and extension targets Add a shared App Group entitlement to both targets In the main app, call: let center = DeviceActivityCenter() center.stopMonitoring([.myActivity]) let schedule = DeviceActivitySchedule( intervalStart: DateComponents(hour: 17, minute: 30), intervalEnd: DateComponents(hour: 17, minute: 45), repeats: true ) try center.startMonitoring(.myActivity, during: schedule) Verify registration succeeds: DeviceActivityCenter().activities.contains(.myActivity) returns true Background the app completely and wait for the intervalStart time (5:30 PM in this example) Expected Result: intervalDidStart(for:) is called in the extension process at 5:30 PM. ManagedSettings shields are applied without any user interaction. Actual Result: intervalDidStart(for:) is never called. No extension process is launched. Filtering Console.app for deviceactivityd on the device returns 0 messages — the daemon produces no logs whatsoever despite an active registered schedule. Shields are never applied. Additional Evidence: Third-party apps using DeviceActivity (e.g. Prayer Lock) successfully apply shields at scheduled times on the same device and OS version, confirming the framework is not universally broken Filtering Console.app for the app's bundle ID at the trigger time shows the main app process applying shields via a UNCalendarNotificationTrigger fallback — but no extension process activity DeviceActivityCenter().activities correctly lists the registered activity before and after the trigger time, confirming the schedule registration API is functional Environment: iOS 26.3.1 Physical device (required for FamilyControls) Development-signed build with com.apple.developer.family-controls entitlement provisioned App Group shared between main app and extension targets

Compensating for IMU (accelerometer) thermal drift - getting device temperature?
I’m running into a hardware reality. MEMS sensor thermal drift. If a user zeroes out the tilt indoors at 20°C and then takes the phone outside in the cold, the accelerometer baseline shifts just enough as the device cools to throw off the readings. I want to apply a simple thermal compensation curve to the CoreMotion data to keep the "zero" perfectly level regardless of the weather. However, ProcessInfo.thermalState only gives broad buckets (nominal, fair, etc.) which doesn't help me calculate a continuous offset for a phone cooling down degree by degree. Is there any public API, or even a proxy metric, that can give me a rough battery or internal temperature integer? I don’t need high resolution decimals. Just a general device temp to offset the hardware drift. Any undocumented tricks or proxy metrics anyone has used to handle this?

Custom icons for folder aliases not showing
Problem: custom icons for folder aliases not showing System drive and external drive custom alias folder icons don't showup on desktop or external drive (OS14.6 Sonoma 2023); they only show-up as plain folders or with an odd document icon. Alias doesn't connect to image; however it's there, easily accessible via spacebar. Finder doesn't save the custom icon to the alias. See below for workaround. Summary: I have custom alias icons on my desktop linking to their source files on the system drive and external drive.. however they do not display the custom icon. After upgrading from OS10.14 Mojave to OS14.6 Sonoma 2023, system drive & external drive custom alias icons no longer display the icon on either drive (there is a work-around for Mojave; see history section). Personal impact: hampered file navigation and workflow; I'm lost, can't tell where anything is; not having my icons makes it especially difficult to navigate my files and hampers my workflow significantly. Desired outcome: all custom icons for folder aliases linking to source files (on system & external drives) appear on the desktop, and in all directories on system & external drives (including encrypted external drives). Status.. August 2024: called apple support, they said there is no solution, and there are no plans to fix it, and no plans for a fix in OS 15 Sequoia (in public beta now) Action: ❯ leave feedback at https://www.apple.com/feedback/macos/ ❯ join this campaign to fix this once and for all! -- After 20 years of dealing with this issue.. we need to fix this. History: ▪ OS 10.14 Mojave 2018: external drive alias icons don't work; because upon startup, the icon images for these files disappear; because when system starts it loads the system drive icons but not the external drive icons because it's password protected, hence icon information does not get loaded; alias icons can't connect with unmounted external drive @ boot; however it's there, easily accessible via spacebar the FIX: alias the icons on the desktop each time after boot, however the names are altered ▪ OS X 10.11 El Cap 2015: drag the icons to a folder then back to desktop.. sometimes this works I stayed on OS9 as long as possible because of the OS10 icon problem ▪ OS 9: all custom alias folder icons worked fine Givens: space bar has fast access to icon -highlight alias and press space bar -- seems that it would be a simple solution, since the image is there -- get info for alias also has the image in preview How to make a custom icon: open a pic (typically from a screenshot; .png), select image with cursor with shift key down (for a perfect square), copy ⌘C, click target folder, get info ⌘I, click on folder icon on top left corner, paste ⌘V Fix -- How? --make a solution approach for a macOS dev? some bash process to link to icon; how to access icon Swift? process to renew the alias icon process goes through all desktop icons.. fixes them; new icon, correct name routine where all icons on desktop link to their files easily making a new alias.. as easy as making a regular alias; cammand L, etc make alias search for the image app that makes alias create custom desktop.. a GUI w links -- INTERIM FIX / WORKAROUND create a new folder on your desktop, name it, place it's alias inside the folder, fix the icon, when you open the desktop folder, you will then have to click on the alias --this is very time-consuming and tedious note: there may be easier options for OSs prior to Sonoma; review History section workflow: symbol note: ⇧ shift, ⌃ control, ⌥ option, ⌘ cammand create new folder on desktop ⌘⇧N , name it.. if the name is already taken by the alias, change the alias's name; for example.. alias it ⌘^A click on this new folder then ⌘I (get info) click on the alias, open source location ⌘R (or ⌘⌥^A on older OSs), click on source file (if not highlighted) then ⌘I (get info) , click on folder icon on top left corner, copy ⌘C click on the get-info window you opened for the new folder, click on folder icon on top left corner, paste ⌘V (if not working see ¹ below), close each of these windows with ⌘W place the associated aliased folder into the new folder you can also do this in groups of folders (3-6 seems is optimal).. for example.. move 3 alias icons to clear area on desktop, create 3 new folders and place them below the aliases, select all aliases and ⌘C, open a text document and ⌘V, fix names & name new folders, select new folders, ⌘I, select target aliases, ⌘R, ⌘I for each, move the alias windows below the new folder windows, copy/paste icons from source to new file, close these windows, place alias folders into new folders ¹ if paste function not working.. move on to the next folder and come back.. it can be moody, if it's not working at all.. restart the computer note2: some icons now have a yellow streak at the bottom let us know if you have any solutions or workarounds, or can code this (provide a script or app)

Cellular not initializing on iPadOS 26.4 (resolved by network reset)
We are seeing an issue after updating iPads to iPadOS 26.4 where cellular service is lost until network settings are reset. Environment: Devices managed via Apple Business Manager and Microsoft Intune Carrier: Verizon Confirmed affected devices: iPad (9th generation) eSIM Behavior: After update, device shows no cellular service No prompt to re-activate or re-add the cellular plan The plan appears to still be present on the device Workaround observed: Resetting Network Settings restores service Notes: This does not appear to be a provisioning issue (no need to re-add eSIM) Behavior suggests the cellular/eSIM state may not be initializing correctly after update Toggling Cellular or Airplane mode has not yet been tested for service restoration. We have not yet confirmed whether devices using a physical SIM are affected Still gathering data on scope across additional iPad models Additional observation: We have not observed this behavior on iPhones (e.g., iPhone 16 on iOS 26.4 with LTE remains unaffected) Has anyone else observed similar behavior on iPadOS 26.4, particularly on managed devices or eSIM configurations?

Updating widgets using using Tunnel.appEx
Hi, i searched some information about how widgetKit updates widgets using "reloadAllTimelines/reloadAllControls" and i know about daily limit for apps to update their widgets. I only care about how to notify user instantly about vpn status change even if app is terminated and user launch vpn connection from ControlCenter(system widget) or SysSettings, is there a way to update my app's contolCenter widgets from Tunnel if widget and tunnel extensions already have same appGroup defaults?

Transaction.currentEntitlements sometimes does not emit a result until device is reboot
I have the typical StoreKit 2 manager class, where I check currentEntitlements for subscription. I have filed a feedback (FB22349195), I hope someone can take a look at it. func updateCustomerProductStatus() async { var activeSubscription: String? = nil // BUG: In some cases the currentEntitlements does not emit a transaction until the device is reboot for await result in Transaction.currentEntitlements { print("Found transaction: \(result)") // This print does not appear until a restart! do { let transaction = try checkVerified(result) // Skip revoked transactions if transaction.revocationDate != nil { print("Skipping revoked transaction for \(transaction.productID)") continue } // Skip expired subscriptions if let expirationDate = transaction.expirationDate, expirationDate < Date() { print("Skipping expired subscription for \(transaction.productID)") continue } // Check product type switch transaction.productType { case .autoRenewable: activeSubscription = transaction.productID default: break } } catch { print("Unable to verify transaction: \(error)") } } // Update state once after processing all entitlements self.activeSubscription = activeSubscription print("updateCustomerProductStatus() activeSubscription: \(activeSubscription ?? "nil")") } There is some unexpected behavior where the currentEntitlements does not emit a result until the iPhone device is reboot. This bug appeared in iOS 26.4 (and in the betas).

Family controls distribution request (timeline info)
Hello, I submitted a request for the Family Controls (Distribution) entitlement, but haven't received status update regarding approval/rejection etc. I submitted a previous contact support ticket as well. I'm wondering the timeline and also if my request went through - currently it says 'submitted' but it's remained this way for a while... I've had other developers in communities saying they were approved earlier, so curious if it's an app issue. Thank you

NETransparentProxyProvider stops intercepting flows after sleep/wake cycle on macOS intermittently
I am seeing an issue with NETransparentProxyProvider where the extension successfully transitions from sleep to wake, but stops receiving handleNewFlow(_:) calls. Only below two methods gets called, We don't apply rules in these methods: override func wake() override func sleep(completionHandler: @escaping () -> Void) This breaking complete proxy workflow as it stops intercepting traffics. We are not observing this issues always. FYI: com.apple.developer.endpoint-security.client is not present in .entitlement file. I am not sure adding this will help. Any possibilities nesessionmanager might fail to re-bind the traffic rules for this extensions? Any thing we can do to avoid this issues?

Memory Leak in new structured concurrency Network Framework API's
After implementing the new structured concurrency API's for Network framework, we are noticing a few memory leaks in the Network framework when using API's like onViabilityUpdate and onBetterPathUpdate. Whenever a previously established connection is disconnected, the NWConnection object is never released by the Network framework when we use the 2 API's mentioned. Irrespective of what goes inside these handlers(or leave it empty), the connection object is leaking. If I comment out the handlers, there is no memory leak. Posting this here in the forum to understand if others have encountered similar issues and found a workaround? Raised a feedback assistant request with all the details and a sample app here: FB22339653

Allow to open parent app from ShieldActionDelegate: `ShieldActionResponse.openParentApp`
Hello, I am the developer of an app called one sec which helps users to spend less time on social media: https://one-sec.app Therefore, we make heavy use of the Screen Time API, and thus ManagedSettings and ShieldActionDelegate. One feature of one sec is the so-called “Doom Scroll Emergency Brake”. This blocks a target app after a certain usage threshold (e.g. 5 minutes) and requires going through an intervention (e.g. breathing exercise) to unlock more time. That added friction makes it very effective in reducing time spent on apps. One thing that is confusing for our users is the way they are prompted to unlock more time, if they want to. They have to: Have Push Notifications enabled for one sec Exempt one sec’s notifications from being delayed by AI prioritization (otherwise they are delayed by ca. 10s) Ensure that push notifications can be delivered during foci. Understand that they have to tap on the notification, which is not very straight-forward because it does not make sense from the user’s UX perspective. This is an artificial limitation of Apple’s screen time framework which has no reason (no security / privacy implications here…). Screenshots of the current flow attached. If would be much more reasonable if there was a new ShieldActionResponse.openParentApp value that can be returned from the completion handler of the ShieldActionDelegate.handle(…) callback. We have seen different apps use private API to achieve this, but we are afraid to do the same to avoid getting banned from the App Store. It would be fair if Apple would level the playground for all apps and offer such an API officially. – Frederik PS: Tracked under FB22347946, FB18846650, FB15500681, FB15079668, FB10393561 (all without responses so far…)

FamilyControls individual authorization: No way to detect revocation while app is backgrounded
We are developing an MDM agent app that uses FamilyControls with .individual authorization to enforce Screen Time restrictions (app blocking, domain blocking via ManagedSettingsStore and DeviceActivityCenter). The Problem We are actively subscribing to AuthorizationCenter.shared.$authorizationStatus to detect authorization changes. However, when the user revokes the app's FamilyControls authorization through Settings (either via Settings > Screen Time > Apps With Screen Time Access, or Settings > Apps > [Our App]), the publisher does not emit any value. All ManagedSettingsStore restrictions are lifted immediately by the system, but our app receives no notification of this change. The only scenario where the publisher reliably emits is when a debugger is attached (i.e., running directly from Xcode). Without the debugger, the publisher is completely silent — even when the app returns to foreground. Code Example We tried subscribing directly to AuthorizationCenter.shared.$authorizationStatus with no intermediary, exactly as shown in the documentation: AuthorizationCenter.shared.$authorizationStatus .sink { status in print("[DIRECT] authorizationStatus emitted: \(status)") } .store(in: &cancellables) This subscription is set up at app launch and stored in cancellables. The result is the same — the publisher does not emit when the user revokes authorization in Settings without a debugger attached. Documentation Reference The documentation for authorizationStatus states: "The status may change due to external events, such as a child graduating to an adult account, or a parent or guardian changing the status in Settings." And: "The system sets this property only after a call to requestAuthorization(for:) succeeds. It then updates the property until a call to revokeAuthorization(completionHandler:) succeeds or your app exits." This suggests the publisher should emit when the status is changed via Settings, but in our testing it does not — unless a debugger is attached. What We Verified We tested with a development-signed build (which includes the com.apple.developer.family-controls entitlement), launched from Xcode, then disconnected the debugger, killed the app, and relaunched from the home screen. Scenario Publisher emits on revocation? Running from Xcode (debugger attached) Yes, immediately Development-signed build (no debugger) No — silent even on foreground return We also confirmed: MDM configuration profiles can disable Screen Time entirely, but cannot restrict the per-app authorization toggle — the user can always freely revoke the app's Screen Time access The Security Gap This creates a significant gap for parental controls use cases: User leaves the app (app goes to background) User goes to Settings and disables Screen Time access for the app All restrictions are immediately lifted User uses the device freely User re-enables Screen Time access and opens the app Everything syncs back to normal — administrator never knows Questions Is there any supported mechanism to receive a notification (background or foreground) when FamilyControls individual authorization is revoked? We are subscribing to AuthorizationCenter.shared.$authorizationStatus but it does not emit. Is the $authorizationStatus publisher expected to work only when a debugger is attached? Is this a known limitation or a bug? Can DeviceActivityMonitor extension detect authorization revocation? Based on documentation it appears limited to schedule/threshold events, but we haven't confirmed this. Is there a planned API improvement to address this gap? Environment iOS 26.2 Xcode 26.3 Swift 6.2.4 FamilyControls .individual authorization Related Threads Screen time API can be disabled easily Changing Screen Time Passcode does not protect apps

swift: Calling "/usr/bin/defaults" returns no data
I'd like to create a small helper app for new students do read/write User default settings. Since it was not possible using the UserDefaults class I decided to use the "/usr/bin/defaults". Unfortuntely it seems not to return anything. Debug output shows "Got data: 0 bytes" Here is a sample code: import SwiftUI func readDefaults(domain : String, key :String) -> String { let cmdPath = "/usr/bin/defaults" //let cmdPath = "/bin/ls" let cmd = Process() let pipe = Pipe() cmd.standardOutput = pipe cmd.standardError = pipe cmd.executableURL = URL(fileURLWithPath: cmdPath, isDirectory: false, relativeTo: nil) cmd.arguments = ["read", domain, key] //cmd.arguments = ["/", "/Library"] print("Shell command: \(cmdPath) \(cmd.arguments?.joined(separator: " ") ?? "")") var d : Data? do { try cmd.run() d = pipe.fileHandleForReading.readDataToEndOfFile() cmd.waitUntilExit() } catch let e as NSError { return "ERROR \(e.code): \(e.localizedDescription)" } catch { return "ERROR: call failed!" } // get pipe output and write is to stdout guard let d else { return "ERROR: Can't get pipe output from command!" } print("Got data: \(d)") if let s = String(data: d, encoding: String.Encoding.utf8) { print("Got result: \(s)") return s } else { return "ERROR: No output from pipe." } } struct ContentView: View { let foo = readDefaults(domain: "com.apple.Finder", key: "ShowHardDrivesOnDesktop") var body: some View { VStack { Text("ShowHardDrivesOnDesktop: \(foo.description)") } .padding() } } #Preview { ContentView() } This code works well e.g. for "ls" when the comments are changed for cmdPath and cmd.arguments. What do I miss in order to get it working with defaults?

Xcode 26.4 breaks compilation: Sending 'activity' risks causing data races
After updating Xcode and SDK to 26.4, I'm now getting an concurrency error when trying to update or end live activities with the following code that built successfully before: // Get list of active activities let allActivities = Activity<ArbeitszeitWidgetAttributes>.activities // Cancel all active activities Task { for activity in allActivities { await activity.end(nil, dismissalPolicy: .immediate) } } Sending 'activity' risks causing data races. Sending main actor-isolated 'activity' to @concurrent instance method 'update' risks causing data races between @concurrent and main actor-isolated uses I'm currently using nonisolated(unsafe) let activity = activity await activity.end(nil, dismissalPolicy: .immediate) to get it to compile again. What's the best approach here?

Brazil Digital ECA Eligibility after the 26.4 Release
Hi, Regarding the Brazil Digital ECA (DECA) requirements, which became effective on March 17, 2026. Following the guidance for regulated regions, we have been testing the eligibility check with the iOS 26.4 release. We previously confirmed that isEligibleForAgeFeatures was returning true for users in the Brazil region, which allowed us to verify our age-gating implementation. A few questions follow on this eligibility check: We have observed in manual testing that specific devices which returned true as recently as March 23rd are now returning false today, despite no changes to the OS build or account settings. Does this indicate a change in the server-side eligibility heuristics? Why would isEligibleForAgeFeatures stop returning true for a region where the law is now in force? Has the guidance on how to evaluate these properties for Brazil changed with the transition to the stable 26.4 release? Thank you!
