Hello Apple Developer Community,
I'm experiencing a persistent issue with my React Native/Expo app that I've been trying to resolve for weeks. I'm hoping someone here has encountered and solved this problem.
The Problem: • My app works perfectly in development (Expo Go, local builds, simulators) • When built for production and installed via TestFlight, it shows only a white screen • The app launches successfully (no crashes) but never renders any UI • This happens consistently across multiple builds and attempts
Technical Details: • Framework: React Native 0.79.5 with Expo SDK 53 • Backend: Supabase • Navigation: React Navigation
What I've Tried: ✅ Created missing .env file with environment variables ✅ Installed missing peer dependencies (expo-font) ✅ Ran npx expo-doctor - all checks pass ✅ Added error boundaries and loading screens ✅ Incremented build numbers and rebuilt multiple times ✅ Verified Supabase credentials are correct ✅ Checked native iOS logs - app launches successfully, no crashes
Key Observations: Works in Expo Go ✅ Works in development builds ✅ Fails in production builds ❌ No JavaScript errors visible in system logs App process runs stable (no crashes)
Questions: • Has anyone encountered this specific issue with React Native/Expo production builds? • Are there known issues with Metro bundler in production builds? • Could this be related to JavaScript bundle loading in production? • Are there specific EAS Build configurations that might cause this?
