[iOS] Error configuring Amplify #208
Description
Hello,
I would like to test the Liveness SDK for iOS (I've already used it on Android and React).
I have both a dev and a prod Amplify backend, so I did the following:
- Cloned the repository.
- Opened HostApp.xcodeproj using Xcode.
- Ran amplify pull --appId <app_id> --envName dev
- Compiled & ran the app.
- Clicked "Sign In"
Nothing is showing up, and in the console I see the following log:
Adding plugin: AWSCognitoAuthPlugin.AWSCognitoAuthPlugin)
