tvOS 26.2 crash in _UIMotionEffectApplicator (NSFastEnumerationMutationHandler) #53
Description
Summary
On tvOS 26.2 (23K54) we’re seeing an EXC_CRASH (SIGABRT) where UIKit aborts during focus/motion-effect handling.
The exception backtrace repeatedly shows:
__NSFastEnumerationMutationHandler_UIMotionEffectApplicator applyMotionEffect:toViews:..._UIMotionEffectEngine _handleLatestDeviceMotion_UIFocusEffectsController startRollbackAnimation
This appears to be UIKit-internal (no actionable app frames in the exception backtrace).
Environment
- App: Reefy (
com.jmhunter.reefy) - Version: 1.1.1 (11) (TestFlight beta)
- Devices: Apple TV 4K / AppleTV6,2 (from crash logs)
- OS: Apple TVOS 26.2 (23K54)
- Source: crash reports downloaded from Xcode Organizer
Repro attempt checklist
- Install build 11 on tvOS 26.2
- Rapidly move focus around lists/grids
- Open/close overlays/menus quickly to trigger focus rollback animations
- Observe crash to home screen
