[SOLVED] React Native M1 Mac build failure with target "React-Codegen"

React Native M1 Mac build failure with target "React-Codegen"

When I run the command npx react-native run-ios in my terminal on my Mac I receive the error

CompileC /Users/jessicageorge-mannella/Library/Developer/Xcode/DerivedData/AwesomeProject-ctnixtnnzajiwuhfvbyaxlajljew/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/React-Codegen.build/Objects-normal/arm64/FBReactNativeSpec-generated.o /Users/jessicageorge-mannella/Documents/testing/AwesomeProject/ios/build/generated/ios/FBReactNativeSpec/FBReactNativeSpec-generated.mm normal arm64 objective-c++ com.apple.compilers.llvm.clang.1_0.compiler (in target 'React-Codegen' from project 'Pods')
(1 failure)

I'm running react native 0.71.5, ruby version 2.6.10, cocoapods version 1.11.3, node version 18.15.0, Xcode version 14.3 and I tried even re-installing MacOS on my laptop in attempt to delete broken version installs. Here's the full list of my installed packages in relation to react-native as-well as some system information

Solution

This is a known issue with react-native that was reported on March 31st in the react-native GitHub repository. It is related to incompatibility between Xcode 14.3 and react-native versions prior to v0.71.6.

v.0.71.6 has been released that resolves the issue by changing the minimum targeted iOS version to 12.4. Prior to this version being released there was a suggested patch that could be applied to v0.71.5.

And for older versions of react-native (e.g., v0.70.6) a different suggested patch may be applied instead.
