Reproducible demo or steps to reproduce from a blank project
- Create Expo SDK 54 managed project
- Install react-native-vision-camera@5.0.1, react-native-worklets@0.8.1, react-native-reanimated@4.3.0
- Set newArchEnabled: true in app.json
- Run: eas build -p ios --non-interactive
- EAS automatically assigns Xcode 26 beta for SDK 54
- Build fails in Xcode compilation phase
Note: The "image" field in eas.json to pin Xcode version is rejected by EAS CLI 18.7.0 with "image is not allowed". There is currently no way to opt out of Xcode 26 beta for SDK 54.
Workaround: Downgrading to Expo SDK 53 forces EAS to use Xcode 16.2 and compiles successfully.
