When the iOS build fails, follow this diagnostic process: 1. **Read the build output** — identify the specific error message and file/line 2. **Common issues and fixes:** - **Pod not found / module not found:** Run `cd ios && pod deintegrate && pod install --repo-update` - **Deployment target mismatch:** Check `ios/Podfile` min_ios_version_supported and project settings - **Duplicate symbols:** Check for conflicting pod versions in Podfile.lock - **Code signing:** Check Xcode project signing settings — for dev, use automatic signing - **Metro bundler errors:** Clear cache with `npx react-native start --reset-cache` - **Stale build caches:** `cd ios && xcodebuild clean` then rebuild - **node_modules native code issues:** `rm -rf node_modules && npm install && cd ios && pod install` 3. **If the error is unfamiliar**, search the codebase for related configuration and check the React Native upgrade helper for version-specific breaking changes 4. **After fixing**, verify with `npx react-native run-ios` or `cd ios && xcodebuild -scheme Upkeep -sdk iphonesimulator build`
