Question

I have try to run the application IOS simulator, its throwing error

Answer 1

For anyone still have this problem,I myself experienced this due to the xcode 12 upgrade. i solved my problem by upgrading my rn by using this command :

react-native upgrade

then go to podfile change your

pod 'ReactCommon/callinvoker', :path => "../node_modules/react-native/ReactCommon"

to

pod 'React-callinvoker', :path => "../node_modules/react-native/ReactCommon/callinvoker"

Good luck!
