Tzedakapp: React Native/Expo iOS App Troubleshooting

Tzedakapp — React Native / Expo iOS App

What it is:
- Mobile app for charitable giving — users load a virtual wallet, make daily micro-donations to partner institutions, and track their impact via a gamification system (streaks, XP, levels, achievements)
- Built with React Native 0.81 / Expo SDK 54, TypeScript, Supabase backend, JSC (JavaScriptCore) engine
- Payments via EFI Bank (PIX, Brazil); push notifications for daily and custom reminders
- App is feature-complete and has been in TestFlight

Current status:
- All features are built and working on iOS 17/18
- The app crashes on launch on iOS 26 (current iOS beta), which is the tester's device
- A series of iOS 26 compatibility patches have been applied; the build pipeline (Xcode Cloud) is stable

Tech stack the freelancer must know:
- React Native bare workflow, Expo SDK, CocoaPods, Xcode Cloud CI
- iOS native (Swift/Objective-C) — ability to read crash logs and patch node_modules native code
- Familiarity with iOS 26 beta breaking changes
