Descripción

iOS Xcode build fails with this Syntax error "ios/Pods/Headers/Public/React-Core/React/RCTBridgeModule.h:132:1: Property with 'retain (or strong)' attribute must be of object type"

Description

I am using this RCTBridgeModule to create my own custom bridge module for one of my application. Recently i migrated the app to latest react-native version 0.61.5. Now the iOS xcode build and react-native run ios command build gives me the error "ios/Pods/Headers/Public/React-Core/React/RCTBridgeModule.h:132:1: Property with 'retain (or strong)' attribute must be of object type". The build works fine when i removed the strong keyword from this line below. The strong or retain keyword is not required here as i see the variable methodQueue here is not an object.
