Description

I’m upgrading to RN 0.64.0 (by following the upgrade helper). When building my iOS app via Xcode, I get the following error from FBReactNativeSpec:

Run: “yarn add --dev react-native-codegen” and rebuild IOS project

I got the same error here.

This is an dependency error on react-native@0.64.0. I’ve updated react-native-codegen to version 0.0.7 and the error goes away.

I use yarn so I put it on resolver attribute inside package.json.
