Issue and Reproduction Steps

Building source code through Xcode, the build fails with the following error

.../node_modules/@unimodules/react-native-adapter/ios/UMReactNativeAdapter/Services/UMReactNativeEventEmitter.m:11:1: Illegal redeclaration of property in class extension 'UMReactNativeEventEmitter' (attribute must be 'readwrite', while its primary must be 'readonly')

We use DeviceEventEmitter extensively and it has worked as intended on 0.64.1. Now, trying to get a basic build fails with no further guidance on how to resolve the problem. I don't know what you would need to research this issue. Because DeviceEventEmitter is not a simple library to implement, I wouldn't know how to create a test case for this. If you have any suggestions, I'd be willing to try them.

Another important point. This issue appears to affect only Apple M1 hardware. Another colleague and I with M1's are both affected. One colleague on an Intel Macbook is not.
