Hello Apple Developer community,
I am seeking help with a recurring App Store
rejection under Guideline 2.1(a) - Performance -
App Completeness. My app crashes on launch
specifically on iOS 26.4.2 and I have confirmed
this is a platform-level bug in React Native —
not an issue with my application code.
BACKGROUND
My app is Highway Exit Food Finder — a navigation
utility built with Expo SDK 55 / React Native 0.83.
It has been in review for several weeks and has
been rejected multiple times due to a crash on
launch on iPad Air M3 and iPhone 17 Pro Max
running iOS 26.4.2.
THE CRASH
Every crash log shows the same signature:
Exception: EXC_CRASH (SIGABRT)
Location: ObjCTurboModule::performVoidMethodInvocation
Thread: com.meta.react.turbomodulemanager.queue
The crash occurs during TurboModule initialization
— BEFORE any JavaScript code runs. This means
no application-level code change can fix it.
CONFIRMED PLATFORM BUG
This crash is documented in:
github.com/facebook/react-native/issues/54859
github.com/expo/expo/issues/44680
These issues confirm that React Native's New
Architecture TurboModule system throws an
NSException during async void method invocation
on iOS 26 that cannot be caught, causing SIGABRT.
WHAT I HAVE TRIED
Removed expo-notifications (possible crash source)
Removed react-native-maps
Simplified all screens to static components
Set newArchEnabled: false in app.json
Upgraded to Expo SDK 55
Submitted 17+ builds attempting to fix this
Despite all these changes the crash signature
remains identical across all builds because the
crash happens at the platform level.
MY QUESTIONS
Has anyone successfully gotten a React Native
Expo app approved on App Store Review while
running iOS 26.4.2 on review devices?
Is there a known working configuration for
Expo SDK 55 that avoids the TurboModule crash
on iOS 26?
Has anyone successfully appealed a 2.1(a)
rejection caused by a platform bug rather
than app code?
Can Apple review devices be updated to use
a stable iOS version for reviewing React
Native apps while the iOS 26 compatibility
issues are resolved?
DEVICE AND BUILD INFO
Review device: iPad Air 11-inch M3
OS: iPadOS 26.4.2
Framework: Expo SDK 55 / React Native 0.83
Build tool: EAS Build
All crash logs reference the identical
TurboModule crash signature
Any help or guidance from the community or
Apple engineers who monitor these forums
would be greatly appreciated.
Thank you.
