With React Native 0.60.0, Auth.signIn returns error, but signUp, and confirmSignUp works

Describe the bug

On a fresh new react-native 0.60.0 project

I am able to get Auth.signUp, and Auth.confirmSignUp to work as expected. When I try Auth.SignIn, I get this error: TypeError: Cannot read property 'computeModPow' of undefined.

Attempted Solution 1: Automatically Linking Based on this issue https://github.com/aws-amplify/amplify-js/issues/563, where the suggestion is to run react-native link amazon-cognito-identity-js. This however, with 0.60 provides the following error:

error Unknown dependency. Make sure that the package you are trying to link is already installed in your "node_modules" and present in your "package.json" dependencies.

Attempted Solution 2: Manually Linking drag RNAWSCognito.xcodeproj, then link with library, but building then provides this error: node_modules/amazon-cognito-identity-js/ios/RNAWSCognito.h:4:9: 'React/RCTBridgeModule.h' file not found

Any help would be greatly appreciated!

To Reproduce

Steps to reproduce the behavior:

1. react-native init, ensure you are on latest 0.60.0 version
2. amplify init, then amplify add auth. Once configured, try signing up. Should work.
3. When trying to signIn, you should experience the errors above. Try automatically linking, then manually linking.

Expected behavior

Auth.signIn(username, password) should sign the user in.

• OS: iOS 12.2

What worked for me is doing

1. yarn add amazon-cognito-identity-js or npm install amazon-cognito-identity-js
2. cd ios
3. pod install --repo-update

hope this helps

@VicFrolov can you sign in if you do not have the react native debugger attached?

I get Cannot read property 'USER_ID_FOR_SRP' of undefined if the debugger is attached, but can successfully sign in when not attached.
