React Native App no longer builds after upgrading to XCode12.5

Question

My react native app previously built and ran on a simulator in xcode 11. However since upgrading to xcode 12.5 I get the following build errors

Cannot initialize a parameter of type 'NSArray<id<RCTBridgeModule>> *' with an rvalue of type 'NSArray<Class>*'

Cannot initialize a parameter of type 'NSArray<Class> *' with an lvalue of type 'NSArray<id<RCTBridgeModule>> *__strong'

Cannot initialize a parameter of type 'NSArray<id<RCTBridgeModule>> *' with an lvalue of type 'NSArray<Class> *__strong'

These errors come from react-core which is in my project via cocoapods.

Fixed using github.com/facebook/react-native/issues/…
