Downside Description
I’ve a React Native challenge that runs completely on Android, however exhibits solely a clean white display when working on iOS simulator. When constructing and working via XCode, I can see the app launches however solely shows a white display.
Setting Particulars
- React Native Model: 0.74.5 (upgraded from 0.69.3)
- iOS Improvement Goal: 13.4
- Node.js Model: v18.20.8 (through NVM)
- Platform: macOS Sonoma (x86_64)
- XCode: Constructing for iOS simulator
- Hermes: Enabled ()
hermesEnabled=true

Challenge Configuration

{
RCTAppSetupPrepareApp(utility, false);
RCTBridge *bridge = [[RCTBridge alloc] initWithDelegate:self launchOptions:launchOptions];

if (@obtainable(iOS 13.0, *)) {
rootView.backgroundColor = [UIColor systemBackgroundColor];
} else {
rootView.backgroundColor = [UIColor whiteColor];
}
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];

rootViewController.view = rootView;
self.window.rootViewController = rootViewController;

return YES;
}

Steps Tried
- ✅ Android: App runs completely – all UI elements and navigation work
- ❌ iOS Simulator: Solely exhibits white/clean display
- Clear builds: Deleted
Pods, , ranpod set upPodfile.lock - Metro cache reset:
npx react-native begin --reset-cache - Simulator reset: Erased all content material and settings
Questions
- Why does the React Bridge get invalidated instantly on iOS however work fantastic on Android?
- Is the dSYM warning associated to the clean display subject?
- May there be a problem with the improve from RN 0.69.3 to 0.74.5 affecting iOS particularly?
- Are there any iOS-specific configuration points within the present setup?
Any insights on debugging this iOS-specific subject could be enormously appreciated! Thanks upfront.
