Overview

In Xcode 26.3 and 26.4, when I use Xcode's built-in git functionality to do a "pull" or "fetch", Xcode presents a dialog saying it's performing the operation, but it never completes. The dialog remains on screen with a spinner. My remote repos are stored on a Mac mini on my local network and I access them via SSH. The git command line works fine, as does the tool Git Tower. I've filed this as FB22091014. Has anyone else seen this, and if so, found a solution?

I’m running into an issue using .contactAccessPicker on a device running iOS 26.1 - a blank sheet appears instead of the expected Contact Access Picker. It works on: Simulator (iOS 26.0) Device + Simulator (iOS 18.6) The issue appears specific to real devices on iOS 26.0+. Environment: Device: iPhone 16 Pro iOS Versions Tested: 26.0 and 26.1 Xcode 26.0.1 SwiftUI app, deployment target: iOS 17+ @available(iOS 18.0, *) private var contactPicker: some View { contactsSettingsButton("Title") { showContactPicker = true } .contactAccessPicker(isPresented: $showContactPicker) { _ in Task { await contactManager.fetchContacts() showSelectContacts = true } } } Filed a Feedback: FB20929400 Is there a known workaround?

I’m developing a share extension for iOS 26 with Xcode 26. When the extension’s sheet appears, it always shows a full white background, even though iOS 26 introduces a new “Liquid Glass” effect for partial sheets. Expected: The sheet background should use the iOS 26 glassmorphism effect as seen in full apps. Actual behavior: Custom sheets in my app get the glass effect, but the native system sheet in the share extension always opens as plain white. Steps to reproduce: Create a share extension using UIKit Present any UIViewController as the main view Set modalPresentationStyle = .pageSheet (or leave as default) Observe solid white background, not glassmorphism Sample code: swift override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .clear preferredContentSize = CGSize(width: UIScreen.main.bounds.width, height: 300) } Troubleshooting attempted: Tried adding UIVisualEffectView with system blur/materials Removed all custom backgrounds Set modalPresentationStyle explicitly Questions: Is it possible to enable or force the Liquid Glass effect in share extensions on iOS 26? Is this a limitation by design or a potential bug? Any workaround to make extension sheet backgrounds match system glass appearance?

Any idea when will the results of Swift Student Challenge be declared?

Kevin's Guide to DEXT Signing The question of "How do I sign a DEXT" comes up a lot, so this post is my attempt to describe both what the issues are and the best current solutions are. So... The Problems: When DEXTs were originally introduced, the recommended development signing process required disabling SIP and local signing. There is a newer, much simpler process that's built on Xcode's integrated code-signing support; however, that newer process has not yet been integrated into the documentation library. In addition, while the older flow still works, many of the details it describes are no longer correct due to changes to Xcode and the developer portal. DriverKit's use of individually customized entitlements is different than the other entitlements on our platform, and Xcode's support for it is somewhat incomplete and buggy. The situation has improved considerably over time, particularly from Xcode 15 and Xcode 16, but there are still issues that are not fully resolved. To address #1, we introduced "development" entitlement variants of all DriverKit entitlements. These entitlement variants are ONLY available in development-signed builds, but they're available on all paid developer accounts without any special approval. They also allow a DEXT to match against any hardware, greatly simplifying working with development or prototype hardware which may not match the configuration of a final product. Unfortunately, this also means that DEXT developers will always have at least two entitlement variants (the public development variant and the "private" approved entitlement), which is what then causes the problem I mentioned in #2. The Automatic Solution: If you're using Xcode 16 or above, then Xcode's Automatic code sign support will work all DEXT Families, with the exception of distribution signing the PCI and USB Families. For completeness, here is how that Automatic flow should work: Change the code signing configuration to "Automatic". Add the capability using Xcode. (USB & PCI) Edit your Entitlement.plist to include the correct "Development Only" configuration: USB Development Only Configuration: <key>com.apple.developer.driverkit.transport.usb</key> <array> <dict> <key>idVendor</key> <string>*</string> </dict> </array> PCI Development Only Configuration: <key>com.apple.developer.driverkit.transport.pci</key> <array> <dict> <key>IOPCIPrimaryMatch</key> <string>0xFFFFFFFF&amp;0x00000000</string> </dict> </array> If you've been approved for one of these entitlements, the one oddity you'll see is that adding your approved capability will add both the approved AND the development variant, while deleting either will delete both. This is a visual side effect of #2 above; however, aside from the exception described below, it can be ignored. Similarly, you can sign distribution builds by creating a build archive and then exporting the build using the standard Xcode flow. Debugging Automatic Code-signing In a new project, the flow I describe above should just work; however, if you're converting an existing project, you may get code signing errors, generally complaining about how the provisioning profile configuration doesn't match. In most cases, this happens because Xcode is choosing to reuse a previously downloaded profile with an older configuration instead of generating a new configuration which would then include the configuration changes you made. Currently, you can find these profile files in: ~/Library/Developer/Xcode/UserData/Provisioning Profiles ...which can make it easier to find and delete the specific profile (if you choose). However, one recommendation I'd have here is to not treat the contents of that folder as "precious" or special. What automatic code signing actually does is generate provisioning profiles "on demand", so if you delete an automatic profile... Xcode will just generate it again at the next build. Manually generating profiles is more cumbersome, but the solution there is to preserve them as a separate resource, probably as part of your project data, NOT to just "lose" them in the folder here. If they get deleted from Xcode's store, then you can just copy them back in from your own store (or using Xcode, which can manually download profiles as well). The advantage of this approach is that when profiles "pile up" over time (which they tend to do), you can just delete[1] all of them then let Xcode regenerate the ones you're actually trying to investigate. In terms of looking at their contents, TN3125: Inside Code Signing: Provisioning Profiles has the details of how to see exactly what's there. [1] Moving them somewhere else works too, but could indicate a fear of commitment. __ Kevin Elliott DTS Engineer, CoreOS/Hardware

Hey We have noticed a change in the retry behavior of Apple Server Notifications webhooks V2 starting around March 12–13, 2026. Previously, when our webhook endpoint returned an HTTP 400 response, Apple would retry the notification delivery multiple times according to the documented retry policy. However, beginning around March 12–13, it appears that Apple no longer retries the webhook when a 400 response is returned. The notification is sent only once and no further retry attempts are made. From our understanding of the documentation, retries should occur when delivery fails, and historically we observed retries even for some 4xx responses. We would like to confirm: Has Apple recently changed the retry behavior for Server Notifications? Are HTTP 4xx responses (specifically 400) now considered terminal failures that will not trigger retries? Is this change intentional or related to a rollout in the webhook delivery system? We have called the "Notification History" endpoint for some users who purchased a sub and we are only getting one attempt with the following data in it: { attemptDate: 1773469202552, (2026-03-14T06:20:02.552Z) sendAttemptResult: 'UNSUCCESSFUL_HTTP_RESPONSE_CODE', } This was 2 days ago, based on the docs, the user should have a few attempts at least. This behavior change affects systems that rely on retries to handle temporary validation issues or transient failures. Thanks!

Every time I try to focus on the subtitle field in the App Clip section, I encounter an error (as shown in the attached screenshot). This is blocking us from uploading a critical version of our app. We need assistance to proceed with the submission. I’ve already tried using Chrome, Safari and Firefox, but the issue persists.

The man page of copyfile sates the following: COPYFILE_CLONE [..] Note also that there is no support for cloning directories" COPYFILE_CLONE_FORCE [...] Note also that there is no support for cloning directories: if a directory is provided as the source, an error will be returned. Now the man page for clonefile: > Cloning directories with these functions is strongly discouraged. Use copyfile(3) to clone directories instead. -- So am I to enumerate the content of a directory build subfolders along the way in the target destination and clone each file inside individually? If I recall NSFileManager seems to clone a large directory instantly (edit actually I remembered wrong NSFileManager does not do this. Finder seems to copy instead of clone as well). On further inspection, clonefile states that it can do this, but it is discouraged. Interesting. I wonder why. If src names a directory, the directory hierarchy is cloned as if each item was cloned individually. However, the use of clonefile(2) to clone directory hierarchies is strongly discouraged. Use copyfile(3) instead for copying directories. P.S. - Forgive me if I posting this in the wrong category, I couldn't find a "category" in the list of available categories on these forums that seems appropriate for this question.

I am trying on iOS 16.1.1 the Nearby Interaction framework. I am testing it on two iPhones 14 Pro Max. The supportsDirectionMeasurement property returns false (!) and the direction property on the NINearbyObjects is nil. Has someone experienced the same issue?

One app submitted Feb 14th, one app submitted Feb 25th. Both apps are showing "Waiting for review". Neither has been rejected, not have any action taken place. I have one previous app published (Submitted June 30th, approved 1 July), but this is the first try for both of these apps. I put in a support ticket asking status of the first app but no response. Ca n anyone here confirm that I've done the submission right and am just waiting on Apple based on the screen shot attached? For anyone from apple that wants to look into it, the app is: SKU: EX1749925971937 Apple ID: 6747297536

[Submitted as FB21961572] When navigating from a tile in a scrolling LazyVGrid to a child view using .navigationTransition(.zoom) and then returning, the source tile can lag behind the rest of the grid if scrolling starts immediately after returning. The lag becomes more pronounced as tile content gets more complex; in this simplified sample, it can seem subtle, but in production-style tiles (as used in both of my apps), it is clearly visible and noticeable. This may be related to another issue I recently filed: Source item disappears after swipe-back with .navigationTransition(.zoom) CONFIGURATION Platform: iOS Simulator and physical device Navigation APIs: matchedTransitionSource + navigationTransition(.zoom) Container: ScrollView + LazyVGrid Sample project: ZoomTransition (DisappearingTile).zip REPRO STEPS Create a new iOS project and replace ContentView with the code below. Run the app in sim or physical device Tap any tile in the scrolling grid to navigate to the child view. Return to the grid (back button or edge swipe). Immediately scroll the grid. Watch the tile that was just opened. EXPECTED All tiles should move together as one coherent scrolling grid, with no per-item lag or desynchronization. ACTUAL The tile that was just opened appears to trail behind neighboring tiles for a short time during immediate scrolling after returning.

Same scenario described here: https://forums.aninterestingwebsite.com/forums/thread/738942 User clicked accept for an internal tester invitation sent to their work apple id on their personal device which was signed in with their personal apple id. This seems to have redeemed the code to the users personal account. However, the user has removed themselves from testing the app and we're trying to get their work apple id registered but the invite code that keeps being sent is coming back saying invalid. Things we've tried: We located the last build the user installed on their device and expired the builds deleted / readded the work apple id to internal testing group It's still sending the same invitation code from TestFlight and saying that the code cannot be redeemed.

Hi. The following code causes UI mismatch on iOS26. Keyboard with type decimalPad and appearance as dark is displayed as popUp with wrong colors. Before iOS26 keyboard was regular with correct color scheme. Please advice either how to make the scheme correct or force to display regular keyboard instead of popup. class ViewController: UIViewController { @IBOutlet weak var textField: UITextField! override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. textField.keyboardType = .decimalPad textField.keyboardAppearance = .dark view.backgroundColor = .darkGray } }

Hello, We are testing Wallet passes with iBeacons in iOS 26 Beta. In earlier iOS releases, when a device was in proximity to a registered beacon, the corresponding pass would surface automatically. In iOS 26 Beta, this behavior no longer occurs, even if the pass is already present in Wallet. I have not found documentation of this change in the iOS 26 release notes. Could you please confirm whether this is expected in iOS 26, or if it may be a Beta-specific issue? Any pointers to updated documentation would be appreciated. Thank you.

What is the proper way to pass arguments to printf with multiple variables using ARM64 Apple Silicon? Example: fOutputStr: .asciz "Element[%d] = %d\n" // formated output string for an output of: Element[4] = 9 This code (see below) works on Raspberry Pi 5, on my Mac Studio, I am getting this output, Element[9] = 1871655168 What do I need to do to use printf from an assembly language call with multiple variables?

I’m encountering a strange, sporadic error in FileManager.replaceItemAt(_:withItemAt:) when trying to update files that happen to be stored in cloud containers such as iCloud Drive or Dropbox. Here’s my setup: I have an NSDocument-based app which uses a zip file format (although the error can be reproduced using any kind of file). In my NSDocument.writeToURL: implementation, I do the following: Create a temp folder using FileManager.url(for: .itemReplacementDirectory, in: .userDomainMask, appropriateFor: fileURL, create: true). Copy the original zip file into the temp directory. Update the zip file in the temp directory. Move the updated zip file into place by moving it from the temp directory to the original location using FileManager.replaceItemAt(_:withItemAt:). This all works perfectly - most of the time. However, very occasionally I receive a save error caused by replaceItemAt(_withItemAt:) failing. Saving can work fine for hundreds of times, but then, once in a while, I’ll receive an “operation not permitted” error in replaceItemAt. I have narrowed the issue down and found that it only occurs when the original file is in a cloud container - when FileManager.isUbiquitousItem(at:) returns true for the original fileURL I am trying to replace. (e.g. Because the user has placed the file in iCloud Drive.) Although strangely, the permissions issue seems to be with the temp file rather than with the original (if I try copying or deleting the temp file after this error occurs, I’m not allowed; I am allowed to delete the original though - not that I’d want to of course). Here’s an example of the error thrown by replaceItemAt: Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission to save the file “test-file.txt” in the folder “Dropbox”." UserInfo={NSFileBackupItemLeftBehindLocationKey=file:///var/folders/mt/0snrr8fx7270rm0b14ll5k500000gn/T/TemporaryItems/NSIRD_TempFolderBug_y3UvzP/test-file.txt, NSFileOriginalItemLocationKey=file:///var/folders/mt/0snrr8fx7270rm0b14ll5k500000gn/T/TemporaryItems/NSIRD_TempFolderBug_y3UvzP/test-file.txt, NSURL=file:///Users/username/Library/CloudStorage/Dropbox/test-file.txt, NSFileNewItemLocationKey=file:///Users/username/Library/CloudStorage/Dropbox/test-file.txt, NSUnderlyingError=0xb1e22ff90 {Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission to save the file “test-file.txt” in the folder “NSIRD_TempFolderBug_y3UvzP”."

"Dummy text".write(to: tempURL, atomically: false, encoding: .utf8)) != nil else { return } do { // Use replaceItemAt to safely move the new file into place. _ = try fileManager.replaceItemAt(savingURL, withItemAt: tempURL) print("save succeeded!") try? fileManager.removeItem(at: replacementDirURL) // Clean up. } catch { print("save failed with error: \(error)") // Note: if we try to remove replaceDirURL here or do anything with tempURL we will be refused permission. NSAlert(error: error).runModal() } } If you run this code and set savingURL to a location in a non-cloud container such as your ~/Documents directory, it will run forever, resaving the file over and over again without any problems. But if you run the code and set savingURL to a location in a cloud container, such as in an iCloud Drive folder, it will work fine for a while, but after a few minutes - after maybe 100 saves, maybe 500 - it will throw a permissions error in replaceItemAt. (Note that my real app has all the save code wrapped in file coordination via NSDocument methods, so I don’t believe file coordination to be the problem.) What am I doing wrong here? How do I avoid this error? Thanks in advance for any suggestions.

Hey everyone, I found a possible SwiftData Release-only issue with nested sort descriptors on an optional relationship. In a minimal repro, sorting a @Query by a nested optional relationship key path like: SortDescriptor(\InvestigationPhotoAsset.imageAnalysis?.overallAestheticsScore, order: .reverse) works in Debug, but crashes at runtime in Release. The surprising part is that the crash depends on file layout: if the active SwiftData models and the sort logic are kept in the same Swift file, the app works if the same models are split into separate files, the Release build crashes, 'Debug' will also work The repro was reduced to just two SwiftData models: InvestigationPhotoAsset InvestigationImageAnalysis So this looks less like an app-modeling issue and more like a SwiftData/compiler/codegen issue related to nested sort metadata in optimized builds. If useful, I can also give you a slightly more formal version with a title and code snippet block. Please check out the code example here Has anyone faced something similar?
