Amplify Cognito Auth Module Not Found

[Jukez17]

I have been trying to build the flutter app to the test flight but I keep getting the Module 'amplify_auth_cognito' not found and I have removed the pod folder and then run pod install. But when I look in the symlinks folder under ios folder. Then looking at the amplify auth cognito folder, it seems that there is no ios folder at all.

Is there any reason why the ios folder is missing and is there way to resolve the issue?

Hi @Jukez17, could you share what your configuration and your pubspec.yaml file look like, with any credentials left out.

Hi @Jukez17, could you share what your configuration and your pubspec.yaml file look like, with any credentials left out.

Problem is rather interesting because i can login, register and fetch data from aws totally fine. This happens when im trying to archive to test flight
