1.6.0 (2020-02-04)

Features

• Support lazy load and pagination for API (#1009)
• Separate DataStore List logic out to list provider (#1000)

Behavior Change

• Auth: Fix cancelling hostedUI returning a generic error (#982).

  When a user cancels the sign in flow from Amplify.Auth.signInWithWebUI, the callback will now deliver an error of type AuthError.service, with an underlying error of AWSCognitoAuthError.userCancelled. Previously, the error was a SFAuthenticationError.canceledLogin. The AuthError.service error type will be returned regardless of whether the underlying HostedUI operation was performed via an SFAuthenticationSession or an ASWebAuthenticationSession.

  You can detect the user cancellation case by switching on the error, as in:

  switch result {
    case .success:
        print("SignOut")
    case .failure(let error):
        if case AuthError.service(_, _, let underlyingError) = error,
            case .userCancelled = (underlyingError as? AWSCognitoAuthError) {
            print("User cancelled")
        }
  }

Misc updates

• Auth: Amplify.Auth.signInWithWebUI now automatically uses ASWebAuthenticationSession internally for iOS 13.0+. For older iOS versions, it will fall back to SFAuthenticationSession.
  This release also introduces a new preferPrivateSession flag to AWSAuthWebUISignInOptions during the sign in flow. If preferPrivateSession is set to true during sign in, and the user's preferred browser supports ASWebAuthenticationSession.prefersEphemeralWebBrowserSession, the user will not see a web view displayed when they sign out.

  Amplify.Auth.signInWithWebUI(presentationAnchor: self.view.window!, 
                               options: .preferPrivateSession()) { ... }
