We are experiencing networking issues in our iOS application when it is built with Xcode 16 or later. Our app includes a video conferencing feature that works reliably when built with Xcode 15 or earlier — we can sustain hour-long video sessions without interruption. However, when the app is built using Xcode 16 or higher, network connections drop after 2–3 minutes during a session. This triggers an auto-reconnect, which succeeds, but the connection drops again after another 2–3 minutes. This loop continues indefinitely. Key Details: The issue only occurs in TestFlight builds. When running the app via Xcode debugger, the issue does not occur. The issue is consistently reproducible in TestFlight builds created with Xcode 16 or later. TestFlight builds created with Xcode 15 do not exhibit this issue. All the videoconferencing runs on C and C++ code What We’ve Tried: Reviewed Xcode 16+ release notes but found no relevant changes or deprecations. Verified app configuration and entitlements. Confirmed that no app-side changes occurred between the working and broken builds. Request: We’re seeking guidance on what changes in Xcode 16+ could be affecting networking behavior in release/TestFlight builds. Any insight into relevant build settings, compiler changes, or runtime behavior differences would be greatly appreciated. Thank you in advance for your assistance.

I have a ContentView in my app which includes the line of code FileUploadProgressAttributes. this struct is defined in a file included in the target FileUploadProgressExtension. and it is an ActivityAttributes. in ContentView I imported FileUploadProgressExtension, and the xcode is able to find the FileUploadProgressAttributes during prebuild. but during build, it gives me Undefined symbols for architecture arm64: "FileUploadProgressExtension.FileUploadProgressAttributes.init(filename: Swift.String) -> FileUploadProgressExtension.FileUploadProgressAttributes the workaround i found is to add the file with the FileUploadProgressAttributes to my app's target, but I'm not sure if this is the right thing to do. When Xcode created the extension for me, it added the extension target as a target dependency of my app. so obviously if i added this file to my app target it makes the extension target pointless. First time working with widgets so I'm not sure if I'm missing something.

Hi everyone, We're developing an AR app using Unity with Vuforia for object detection. Our app works well in full-screen mode, including detection and post-detection phases. However, we're facing a specific issue in iPad Split View multitasking mode. Problem: The AR camera (Vuforia-based) freezes during object detection if another app is opened in Split View. Post-detection, everything works fine in Split View. The problem only occurs during detection. Testing Environment: iPadOS 16+ Unity with Vuforia plugin Using EnableMultitaskingCameraAccess() method with AVFoundation to support camera multitasking AR scene is set up properly with detection capabilities in full-screen

I know there has been issues with SFSpeechRecognizer in iOS 17+ inside the simulator. Running into issues with speech not being recognised inside the visionOS 2.4 simulator as well (likely because it borrows from iOS frameworks). Just wondering if anyone has any work arounds or advice for this simulator issue. I can't test on device because I don't have an Apple Vision Pro. Using Swift 6 on Xcode 16.3. Below are the console logs & the code that I am using.

I am on MacOs 15.4.1 which is being deployed with an old version of Ruby ruby 2.6.10 and bundler version 1.17.2. I ran pod install after generating the pods with these versions and during the application compilation there have been several issues reported against pods code.

If I create a playground project that uses a JSONDecoder I get the following error. The LLDB RPC Server has crashed. The crash log is located at ~/Library/Logs/DiagnosticReports and has a prefix 'lldb-rpc-server'. Please file a bug and attach the most recent crash log. I have raised feedback for this, FB17702087, but I hope that there may be a workaround.

Hi Experts, Could you please help. Issue at high level: After Editing a View contains a Table entries, saved and hit back button to display View, Table entries are duplicated or displaying previous and current entries together. Here is my Issue in detailed. List view display, clicking on any row, would navigate to DisplayView of a record. I am displaying a table in DisplayView. DisplayView contains "row" as parameter, and it must be initialized in "init" method, where I use row.key and fetch another table (say ColorTab) using Color.Key. DisplayView contains "NavigationView", with Edit button. it displays fetched Colors. example Red and Green. when user click on Edit, it takes to EditPage. user can remove / add colors. Once user made changes, saved and hit back button. Table entries are duplicated or showing previous and current entries. Options tried, a) init method is only triggering 1st time, not triggering when back button clicked, I failed to use FetchRequest outside of init method, I tried on OnAppear too. i didn't trigger. b) Failed to use FetchRequest inside of var Body too. c) tried using viewContext.refreshAllObjects() .. it is not refreshing the table. Could you please help if there is solution for the issue. Thanks, Bhanu

We can see from App Store Connect under TestFlight tab on the overview that our build got X number of crashes. Problem is that these crashes are not found in Crash feedback tab or not from Xcode Organizer. This problem has been ongoing for us in multiple different app builds now. Is there any suggestions what might cause this problem and how to start solving this? I'm pretty confident that these crashes happen in our network extension (NEPacketTunnelProvider). Note - We have a lot of TestFlight users and to start asking them all separately manual logs from phone might not help us here. (Settings > Privacy > Analytics & Improvements > Analytics Data). Also these crashes have not been reported to us by the users. I suspect that the reason is that the extension kicks automatically back up since we are running VPN there with on demand rules. Meaning that the users might not be able to notice the service crash or shut down because of the automatic restart. Thanks

Hi, I compiled Intel Open Image Denoise library for iOS, and obtained a bunch of dependent dylibs. I want to use these ones in a swift project (via bridging as this is C/C++) targeting the iPad. I understand that it is required to embed these dylibs into frameworks as iOS doesn't allow dylib. Is it necessary to generate one framework for each dylib? If so, how are dependencies between the libraries (and their frameworks) managed? Or, is it possible to generate only one framework embeding all the dependencies?

Hello! I am writing UI tests for an app with OAuth authentication and want to avoid the login screen. I want each developer to store the password and username locally on their machines. The bash script will get the token. I need to access that token from my test target somehow. The idea was to write them to a temporary file that git ignores and access this file from the bundle. But I can't add the file from the build script to the target and make it accessible from the code.

When I use Xcode to develop the apps, the connection to my own Apple Watch is failed. The simulator has been downloaded, but it still displayed"watchOS10.0 Not Installed". The developer options were opened, I click the"trust this computer" but it always display"Connecting to *** Apple Watch". My iPhone can be connected normally.

Where are the local documentation files location on MacOS? None of the existing data on the internet is applicable anymore. Trying to bundle documentation for use in an LLM and the developer site is unusable for crawling. Thanks! *.docset

This question is a component of this question and an extension to this question which has been solved. This situation might feel a pinch constructed but it is a simplified version of one step of the original question. Basically in my app I have a script that outputs a folder with a few files inside of it. This folder is output to $(BUILT_PRODUCTS_DIR)/build/ and is referenced via a PBXBuildFile. Because I put a wait in the script (to simulate a long build I have in my real project) it is very obvious when the script is or isn't run. The goal would be for it to run only when its dependencies have changed. The trick is if I put this script as a "run script" phase within my final target dependency analysis works great. The script only runs when the dependencies are updated. However if I put the "run script" phase into an aggregate target then add it as a Target Dependency in the main target Xcode wants to run the script every time. Regardless of if the dependencies have changed. However if you build just the aggregate target alone everything goes just fine. It only builds when it has to. To me this does not quite make sense. I thought that dependency analysis of the script within my aggregate target would be the same regardless of whether that script was within the aggregate target or the main target. In my app I ideally need the aggregate target to be shared by multiple other targets. While I could put the script in each it would be more foolproof to have them share an aggregate target. Why would dependency analysis come to a different conclusion when the script is within an aggregate target that is a target dependency of the main target? If it helps here is the script and the entire project can be found here on GitHub if you would like to play with it. mkdir -p "${SCRIPT_OUTPUT_FILE_0}/build/" echo "Pausing for 10 seconds before creating files..." sleep 10 cat "${SCRIPT_INPUT_FILE_0}" cat > "${SCRIPT_OUTPUT_FILE_0}/build/index.html" << EOF <!DOCTYPE html> <html> <head> <title>Simple Page</title> </head> <body> <h1>Welcome to Simple Page</h1> <p>Generated at: $(date)</p> </body> </html> EOF cat > "${SCRIPT_OUTPUT_FILE_0}/build/page.html" << 'EOF' <!DOCTYPE html> <html> <head> <title>Simple Page</title> </head> <body> </body> </html> EOF

I've got a 2019 Intel iMac running Sequoia 15.4.1 and Xcode 16.3. Every time I try to view a storyboard Xcode locks up and beachballs on me. It takes minutes to load the file. When I force-quit Xcode, the report that shows up has this as the reason: Processes reached dispatch thread soft limit (64): launchd_sim [96305] [unique pid 194673], launchd_sim [96260] [unique pid 194628] Deadlock: AppleSpell [1494] thread 0x1df0c4 DispatchQueue 313 -> AppleSpell [1494] thread 0x1df0c4 DispatchQueue 313 Deadlock: AppleSpell [1494] thread 0x1df114 DispatchQueue 86 -> AppleSpell [1494] thread 0x1df114 DispatchQueue 86 Blocked by Deadlock: 1 task - AppleSpell [1494] I'm wondering, why is AppleSpell trying to spell-check a plist file? Is there any way to tell AppleSpell to ignore a file?

We are using Unity 6000.0.51f1 for an iOS app for iPhones and iPads. We have added Firebase Crashlytics to the project. We are getting several app crash issues in iPhones and iPads as well. However, in Firebase, there is no record of the crash; the app simply closes on iOS without any error. We are using so many UnityWebRequests for APIs in the project. We optimized these coroutine functions to reduce memory overload, but still we are getting app crashes. What optimization techniques can we employ in the project to address this issue? And what memory optimization techniques, texture techniques, can we use to address this issue? Please help!

As far as I know, there was a time that you can capture GPU workload for opengles game app on iOS using Xcode. However, currently I'm using Xcode version 15.2 and iOS18，it seems the "capture GPU workload" button is always disabled when I'm trying to debug my game app which is using opengles api for graphics rendering no matter switchinng "GPU Frame Capture" to "OpenGL ES" or "Metal" or "Automatically" in the scheme. And I'm not able to capture GPU workload for my game on iOS. The only way to make the "capture GPU workload" button enabled is creating a new project using metal api for graphics rendering. But I don't want to change the graphics API, because it will cause a lot. Does Xcode still support capturing GPU workload for OpenGLES game app on iOS? If not, is there an alternative way?

Hi all, I’m running into an issue with my iOS + Apple Watch app project, and I could really use some advice. My WatchOS app requires an iOS companion for settings and configuration, so both apps need to be distributed together. Here’s how I structured my Xcode project: Main iOS App target WatchOS App target WatchOS Extension target However, I’m very confused about how these targets interact, and things are not working as expected. The problem: I can build and run the WatchOS app and its extension independently in the simulator by selecting their schemes. When I select the main iOS app scheme, I get an error about ITSWatchOnlyContainer in the Info.plist—even though there’s no Info tab for that target in Xcode. I’m able to distribute the WatchOS app by itself, and the extension as well. But I can’t distribute them bundled together as a single package, and I haven’t found any clear resources that explain how to fix this. This is my very first app, and it’s frustrating to get stuck just before the finish line! Project Structure / steps to reproduce Let’s say my project is called MyAppProject, with these targets: MyAppProject Main iOS App Embedded target: MyAppProject Watch App Bundle identifier: com.example.MyAppProject MyAppProject Watch App WKCompanionAppBundleIdentifier: com.example.MyAppProject “Requires iOS App”: YES MyAppProject Extension Bundle identifier: com.example.MyAppProject When running from the MyAppProject scheme, I get this error (even though I can’t see or edit the Info.plist in Xcode for this target): “Please try again later. This app has the ITSWatchOnlyContainer key set in its Info.plist, which identifies it as a shell app surrounding a Watch-only app; these are not installable.” As a result, I can’t distribute the app as a bundle. I’d appreciate help understanding: How should the Info.plist files be configured for each target? What do I do if the Info.plist path seems missing in the Xcode UI? Is there a “correct” way to structure an iOS + WatchOS app for bundled distribution?

I am attempting to generate screenshots at various logical times using a watchOS 11 simulator. % xcrun simctl status_bar "Apple Watch Series 10 (46mm)" override --time 9:06 An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=45): Simulator device failed to complete the requested operation. Operation not supported Underlying error (domain=NSPOSIXErrorDomain, code=45): Status bar overrides not supported on this platform. Operation not supported Using WatchOS Clock Settings gives me at most 59 minutes in which to succeed. Even if I had a physical watch for every series and size, I would have to wait up to 23 hours before being able to generate my marketing screenshots to support various user scenarios. With three settings variations, a minimal wait time to get to good marketable content would be on the order of 1 month per app version.

I have an App that has working audio for most devices except for iOS18 + Air pods pro connected. Eventually I realized that this is due to the Audio Spatialization which is enabled by default. I found a information property list key called AVGameBypassSystemSpatialAudio which can be enabled to true AVGameBypassSystemSpatialAudio and now the audio works for 90% of the game. However my game has a .MP4 which when it is played will be paused when the air pods are connected and after force skipping the video the Spatialization is now enabled and the app no longer has audio. I checked through the logs and found this part mediaplaybackd <<<< FigFilePlayer >>>> itemfig_establishedStereoAudioSpatializationPreferenceForAsset: <0x53451c000|I/OWH.01>: Stereo Spatialization allowed by default due to asset containing video After this line I can see the Spatialization being enabled. Does anyone know how to disable this auto setting of stereo Spatialization by default?
