Reply to Installed Xcode - Canvas fails to boot
Thanks for the post. It seems like you're experiencing issues with Xcode 26.2 on macOS Sequoia. So the preview stops rendering anything in a simple Hello World app? Would you like to post the app here for developers to test and see how it behaves? If so, please share a link to your test project. That'll help us better understand what's going on. If you're not familiar with preparing a test project, take a look at Creating a test project. Verify that both your macOS and Xcode versions are fully updated. Since you're on Sequoia 15.7.3 and Xcode 26.2, check for any available updates for macOS that might address. I would recommend to move to macOS Tahoe. Sometimes, clearing derived data can resolve issues related to indexing and builds. You can do this by navigating to and deleting the contents. If the canvas is causing Xcode to hang, try disabling it temporarily. Open your project settings, navigate to the section, and uncheck “Live Views”. As a more drastic measure, consider

In a comment, @txzkbs said: 感谢您的回复!您提供的几个关于这个问题的问答,我之前就已经尝试过了,今天再次去试,无论是重新让Xcode生成桥接头文件,还是检查other linker.... 最终的结果都是报错: Validation failed (409) The app contains one or more corrupted binaries. Rebuild the app and resubmit. (ID: d9bb0d99-4116-41bb-aa6d-f4cad6353887) 非常奇怪,始终是同样的错误码和错误提示,没有具体的信息,期待您的再次回复,感谢! With some help from a machine translation of what you wrote above, I understand that you tried some things from the threads that my colleague linked to. Can you be specific about what you tried, including the command line tools that you used and the results of those commands? Additionally, if you haven't opened a bug report regarding this with your app's .ipa file attached, please do so and share the FB number here so I can locate it. — Ed Ford,  DTS Engineer

Reply to Uncategorized (Xcode): Unable to find a destination matching the provided destination specifier: { id:45967BD9-44E0-4D5D-8C43-C5437F48836A }
Thanks for the post. Is this a Flutter error? Or is this an Xcode error? Are you able to demonstrate the issue in a test project created from one of Xcode's templates, and using only Apple APIs? If not, you should check with the support resources provided by “Flutter” to get assistance with their software. Unless another developer in the forums has experience with the third-party and can provide assistance. You can find tips on creating and sharing a test project in Creating a Test Project.

Installed Xcode - Canvas fails to boot
Downloaded Xcode 26.2 from App Store. Started new Project, which defaults to hello world. The canvas simulator within fails to finish indexing (paused), or When the canvas is active, the first code change (i.e. just a return key at the end of a line) cause the Xcode program to come to a stop. Have ended Xcode and rebooted a number of times. A number of remedies are posted on the net. All a little different than the other. Is there a current remedy for Xcode 26.2 to this issue available? iMac on Sequoia 15.7.3 , 800 gb of available storage Xcode: 26.2 (24553) Instruments: 26.2 (64573.16) SDKs: DriverKit: 25.2: iOS: 26.2: (23C53) iOS Simulator: 26.2: (23C53) macOS: 26.2: (25C57) tvOS: 26.2: (23K50) tvOS Simulator: 26.2: (23K50) visionOS: 26.2: (23N301) visionOS Simulator: 26.2: (23N301) watchOS: 26.2: (23S303) watchOS Simulator: 26.2: (23S303)

Reply to Reality Composer Timeline unfinished
Thank you for participating in the forums! These forums are for questions about developing software and accessories for Apple platforms. Feature enhancements can be submitted through Feedback Assistant, as well as bug reports. As for the reported timeline issue, I recommend sharing a focused test project in the original thread you created https://developer.apple.com/forums/thread/810868 When sharing a test project, only include any assets, 3rd-party code or frameworks if absolutely required to for this targeted test project to run. Including the versions of iOS and Xcode affected will also help us troubleshoot. Thank you!  Travis Trotto - DTS Engineer

certificates expired, created new certificates and missing Mac App Distribution
Hi, My certificates expired and I created new ones. But now Xcode shows me in Apple Accounts status of Mac App Distribution that the Missing Private... Howto fix the missing private key? I need to sign a .pkg for upload with Transporter. Further I generated a CSR for App License Delivery ALD certificates. https://developer.apple.com/help/account/certificates/create-a-certificate-signing-request/ And with App Store Connected I created new certificates. In Xcode I had to remove the Apple Account and add it again, after altering currency. This procedure was described somewhere because Xcode was not able to connect my account. This is fixed now.

nonisolated Execution Differences Before and After Xcode 26.2
I have an older project that was created before Xcode 26.2. In Xcode versions prior to 26.2, there was no Swift Compiler – Concurrency build setting. With those older versions, the following behavior occurs: a nonisolated function executes off the main thread. class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() run() } private func run() { Task { await runInMainThread() } } func runInMainThread() async { print(>>>> IN runInMainThread(), Thread.isMainThread (Thread.isMainThread)) await runInBackgroundThread() } private nonisolated func runInBackgroundThread() async { print(>>>> IN runInBackgroundThread(), Thread.isMainThread (Thread.isMainThread)) } } Output: >>>> IN runInMainThread(), Thread.isMainThread true >>>> IN runInBackgroundThread(), Thread.isMainThread false However, starting with Xcode 26.2, Apple introduced the Swift Compiler – Concurrency settings. When running the same code with the d

Reply to Crackling speakers on MacBook M1 Pro
Yes, I have the same (currently on my M4 Pro, previously on my M1 Pro). Specifically noticeable if you are running music in the background while working in Xcode. The 'solution' I have is to kill the audio daemon. It will then auto-restart and it's ok for at least a while. Use: 'sudo killall coreaudiod'.

Reply to Content Filter Permission Prompt Not Appearing in TestFlight
[quote='872014022, lilan, /thread/773414?answerId=872014022#872014022, /profile/lilan'] Do you mean that I need to add that line on my entitlements? [/quote] I presume you’re referring to the get-task-allow entitlement. If so, then no, that’s not what I mean. That entitlement is managed by Xcode. It automatically adds it when you sign for development and omits it out when you sign for distribution. Let’s ignore development signing for the moment, because shipping apps are necessarily distribution signed. In that case, you have the three options outlined by TN3134: On supervised devices, the device manager can install a configuration profile that enables your content filter system wide. On managed devices, the device manager can use MDM to install a configuration profile that enables your content filter for specific managed apps, also installed by MDM. If you’re building a Screen Time app, your app can programmatically enable its content filter. This is subject to very specific criteria, outlined in t

Reply to Push To Talk framework doesn't active audio session in background
I've created an example app to demonstrate my problem. It can be found here: https://github.com/egeniq/ptt-audio-activation-test-ios To reproduce, do the following: Change team selection in Xcode. Run the app. Choose join. Tap on the Set remote participant NOW button. See in the log output that the audio session gets activated. Tap on the Clear remote participant button. See in the log output that the audio session gets deactivated. Tap on the Set remote participant after 5s button. Immediately go back to your phone's homescreen. After 5s see in the log output that the remote participant is successfully set. However also note that no audio session activation occurs.

'__abort_with_payload' from CompositorNonUI on visionOS 26.2 (device + simulator, Omniverse streaming)
I am developing a custom app for Apple Vision Pro using Compositor Services to stream content from NVIDIA Omniverse. The app is based on: https://github.com/NVIDIA-Omniverse/apple-configurator-sample Environment: Device: Apple Vision Pro OS Version: visionOS 26.2 Xcode Version: 26.2 The Issue: The application crashes hard (__abort_with_payload) in libsystem_kernel.dylib on Task 6 immediately after initialization. This appears to be a deliberate abort triggered by the compositor, not a typical crash. The issue occurs on both physical device and simulator. Important detail: The console output shows a specific CLIENT BUG assertion. By checking the metadata of the warning, I found that it is related to Library: CompositorNonUI. Relevant console output before abort: Missed 'FrameLimiter' target of 90.0 Hz running compositor services to get IPD, FOV, etc fence tx observer 14f27 timed out after 0.600000 fence tx observer bc1b timed out after 0.600000 BUG IN CLIENT: For mixed reality experiences please use c
