React Native New Architecture (Fabric/TurboModules) error
New Architecture.*error|Fabric.*not supported|Codegen.*failed
Fixes
- 1.Enable New Architecture: newArchEnabled=true in gradle.properties (Android)
- 2.For iOS, set RCT_NEW_ARCH_ENABLED=1 in pod install
- 3.Check that all dependencies support New Architecture — some need native code updates
