how do I implement Sign in with Apple?

To implement "Sign in with Apple," you can follow these general steps:

1. Set Up Your App ID:

   • Go to the Apple Developer portal and configure your App ID to support "Sign in with Apple."

2. Configure Your App:

   • In Xcode, enable "Sign in with Apple" in your app's capabilities.

3. Implement the Sign-In Flow:

   • Use the ASAuthorizationAppleIDButton to present the "Sign in with Apple" button in your app.
   • Handle the authorization request using ASAuthorizationController.

4. Handle the Authorization Response:

   • Implement the ASAuthorizationControllerDelegate methods to handle the success or failure of the sign-in process.

5. Verify the User Identity:

   • On your server, verify the identity token received from Apple to ensure the authenticity of the user.

For more detailed guidance, you can refer to the session Streamline sign-in with passkey upgrades and credential managers which discusses the transition to passkeys and how to streamline the sign-in process.
