I would like to know if there is a way to find out before I send the authorization request if a user is signing up to my app with Apple for the first time, or if he/she is already registered and just signs in.
Basically I have a registration screen in my app, where a user can create two types of users and a login screen where both users can log in. I would like to keep the registration and login separate, so for that I need to know whether its a first sign in with apple.
