@Wallman
Add this to your SingInWithAppleButton's onCompletion handler

if case .success(_) = result { dismiss() }

So that it looks something like this:
_{(assuming you are using the auth-account-linking/final project without modification)}

SignInWithAppleButton(.signIn) { request in
    viewModel.handleSignInWithAppleRequest(request)
  } onCompletion: { result in
    viewModel.handleSignInWithAppleCompletion(result)
      if case .success(_) = result { dismiss() }
  }

I'm making a PR to fix this issue :)
