[Crash] SDK 2.36.0 AWSCognitoAuth launchUsing:uiViewController:completion:

[skyfoxa]

Describe the bug Calling AWSMobileClient.default().showSignIn(navigationController: signInUIOptions: hostedUIOptions: _:) leads to an uncaught exception and crashes the app.

This issue started occurring when we updated the SDK from version 2.35.0 to 2.36.0. It's probably connected to the recent update from SFAuthenticationSession to ASWebAuthenticationSession. It may be the same issue as was discussed here

To Reproduce

Here is our awsconfiguration:

"Auth": {
      "Default": {
        "OAuth": {
          "WebDomain": "...",
          "AppClientId": "....",
          "SignInRedirectURI": "myapp://callback",
          "SignOutRedirectURI": "myapp://signout",
          "Scopes": ["openid", "email", "profile"]
        }
      }
    },

Steps to reproduce the behavior:

1. Call AWSMobileClient.default().showSignIn(navigationController:signInUIOptions:hostedUIOptions:_:)
   • use HostedUIOptions(scopes: ["openid", "email", "profile"], identityProvider: "Google")

Observed Behavior

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'The provided scheme is not valid. A scheme should not include special characters such as ":" or "/".'

Expected Behavior Hosted UI is opened and user can sign in, app doesn't crash.

Hi @skyfoxa! Thanks for opening this issue.

We will take a look and post updates here.

[sebaland]

This should be fixed in the latest release 2.36.1.

Could you please update your dependency and verify? Thanks!

[skyfoxa]

@ruisebas the SDK doesn't crash anymore, however it won't open the hosted UI, calling the AWSMobileClient.default().showSignIn(navigationController: signInUIOptions: hostedUIOptions: _:) method returns this error:

Error Domain=com.apple.AuthenticationServices.WebAuthenticationSession Code=2 "Cannot start ASWebAuthenticationSession without providing presentation context. Set presentationContextProvider before calling -start." UserInfo={NSDebugDescription=Cannot start ASWebAuthenticationSession without providing presentation context. Set presentationContextProvider before calling -start.}

[sebaland]

@skyfoxa my apologies for that.

I've merged a fix to the main branch. Would you be able to verify it it addresses your issues? If you cannot, no worries, we will release a new version for you to try.

Thanks!

[skyfoxa]

@ruisebas I tried it, but it looks https://github.com/aws-amplify/aws-sdk-ios-spm doesn't contain that change yet, I'll probably wait for the release

[sebaland]

@skyfoxa sorry for the delay. The fix has been released in 2.36.2.

Please let us know if you still face any issues. Thanks!
