I've been working with RN projects that have amazon-cognito-identity-js as a dependency in Xcode 12, but I haven't come across an error before. Do you happen to have some reproduction steps?

[johnny-minty]

@amhinson Thanks for the quick response. I will review this today and get back to you with reproduction steps. The problem tends to arise only when using 'use_frameworks' in the Pod file.

@amhinson I've confirmed this only occurs when building with 'use_frameworks!' in the PodFile using XCode12.

Removing it or updating the podspec for the Cognito project to depend on 'React-Core' will resolve the issue.

Steps to reproduce:

1. react-native init amptest

2. Add the following dependencies to package.json and run 'npm install'

   "@aws-amplify/api": "3.2.21",
   "@aws-amplify/auth": "3.4.21",
   "@aws-amplify/core": "3.8.13",
   "amazon-cognito-identity-js": "4.5.10",

3. Open the POD file add 'use_frameworks!' to the top of the file

5. Run pod install in the IOS directory
6. Build from XCode - error occurs:
