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

Hi, we've been developing an XR application for Apple Vision Pro which has worked fine so far. Now that the SDKs have updated to 26.2 (for Xcode and AVP versions) we've run into an error that prevents the app from launching. I get the following error when running the application in the AVP Simulator (building for destination Apple Vision Pro (26.2), and my colleague gets the same error when building for the device itself and launching there. BUG IN CLIENT: For mixed reality experiences please use cp_drawable_compute_projection API Type: Error | Timestamp: 2026-01-13 09:21:57.242191+02:00 | Process: My XR App | Library: CompositorNonUI | TID: 0x75e2c (copied with all metadata) How can we debug this further? The error in the console doesn't seem to give any stack trace or clear pointer to the code which relates to it. I've tried searching for CompositorNonUI, but that doesn't yield any results in our project (nor Google nor the Apple developer forums). There is one post in the forum that has a similar

I am profiling a simple SwiftUI test app on my new iPhone through my new MacBook Pro and everything is version 26.2 (iOS, macOS, Xcode). I run Instruments with the SwiftUI template using all of the default settings and get absolutely zero data after interacting with the app for about 20 seconds. Using the Time Profiler template yields trace data. Trying the SwiftUI template again with the sample Landmarks app has the same issue as my app.

I've developed a Multiplatform app under Xcode 26 (currently using 26.2 17C52). The current destinations of the single target are Mac, iPad and Mac(designed for iPad). The minimum deployments are MacOS 15.6 and iOS 18.6. All destinations build and perform correctly on physical devices (running OS 26 versions). The MacOS version has been submitted successfully to the AppStore for TestFlight usage. However, the iPad version shows a submission validation failure: Missing Info.plist value. A value for the key “WKApplication”, or “WKWatchKitApp” if your project has a WatchKit App Extension target, is required in “xxxxx.app/xxxxx.app” bundle. For details, see: https://developer.apple.com/documentation/watchkit/creating_independent_watchos_apps/setting_up_a_watchos_project (ID: 4911506c-39c3-4b69-a8bb-5e5dcd3dc2fb) The app has no WatchKit version (although one's planned for a future release). The Target's Build Settings include a watchOS Deployment Target and Info.plist values related to WatchKit. The Build

Hi Forum I am working on an ios app with a companion watchos app. The watchos app was made in 2018, it uses watchkit and has a watchkit app target and a watchkit app extension target. When I started working on it, the app was already published and running. More importantly, the watch app was installing on the users watch automatically, when the app was installed on their phones. I came in and made some changes, updated some things and added some smaller features. After uploading to testflight and testing the app there, we sent it for review and updated the app. This updated app, introduced the issue that when users now downloaded the app, the watch app seems to be missing. For me, downloading this new version on either testflight or app store works fine, but whenever my boss or a new user does it, the watch app is missing. I have tried to go back to the older version of the app I started with, but this doesn't seem to change anything. My coworker tried to do do the same thing, uploading the old version, but w

I am building a bundle target for macOS 12 and later using Xcode. The bundle is not a standalone app, but a plug-in that is loaded by a host app. The code is written in Swift and uses the new Span API which is available in the OS-provided standard library in macOS 26 and backdeploys to macOS 10.14.4+. Xcode should instruct the linker to include libswiftCompatibilitySpan.dylib in the compiled bundle to provide this backdeployment, but that does not happen. SwiftPM does this additional linking by adding an rpath. When trying to load the bundle using the NSBundle.loadAndReturnError() API, I get the following error on macOS 15 (and no error on macOS 26): Error Domain=NSCocoaErrorDomain Code=3588 dlopen(.../MyBundle.someBundle/Contents/MacOS/MyBundle, 0x0109): Library not loaded: @rpath/libswiftCompatibilitySpan.dylib Referenced from: .../MyBundle.someBundle/Contents/MacOS/MyBundle Reason: tried: '/usr/lib/swift/libswiftCompatibilitySpan.dylib' (no such file, not in dyld cache), '/System/Volumes
