2 Duplicate symbols for architecture arm64

Question

I'm having an error in react native ios using xcode 12. I installed react-native-sensors and react-native-share, it seems like they have the same classes. Here's the error.

    duplicate symbol '_OBJC_CLASS_$_Utils' in:
    /Users/Fennecteck/Library/Developer/Xcode/DerivedData/runm8-aupqcfeohtwloyeyhjaowldkxzbn/Build/Products/Debug-iphoneos/RNSensors/libRNSensors.a(Utils.o)
    /Users/Fennecteck/Library/Developer/Xcode/DerivedData/runm8-aupqcfeohtwloyeyhjaowldkxzbn/Build/Products/Debug-iphoneos/RNShare/libRNShare.a(Utils.o)
duplicate symbol '_OBJC_METACLASS_$_Utils' in:

ld: 2 duplicate symbols for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I tried 'No Common Blocks' from Yes to No but still having this error. Also removing the -ObjC.

There is conflict of 2 classes in this packages. Latest class was created in react-native-share (https://github.com/react-native-share/react-native-share/compare/v4.0.4...v4.1.0)

I have a same issue and to resolve it I created an issue in repository (https://github.com/react-native-share/react-native-share/issues/913).

To fix it now, better solution is to downgrade version of package, who was latest created this duplicated class

react-native-share from 4.1.0 to 4.0.4 (this is worked for me)
