SmartSwitchAuthenticateGameCenter

Smart Switch Authenticate will logout of the current profile, and switch to the new authentication type. In event the current session was previously an anonymous account, the smart switch will delete that profile. Use this function to keep a clean designflow from anonymous to signed profiles

Authenticate the user using their Game Center id

Method Parameters

Parameter	Description
gameCenterId	The user's Game Center ID — can be the PlayerId, GamePlayerId, or TeamPlayerId from the GKLocalPlayer object
forceCreate	Should a new profile be created for this user if the account does not exist?
timestamp	The timestamp value returned as part of the identity verification signature fetch from Game Center. Required for modern Game Center verification.
publicKeyUrl	The public key URL returned as part of the identity verification signature fetch from Game Center. Required for modern Game Center verification.
signature	The raw signature bytes returned from Game Center (via GetSignature()). Required for modern Game Center verification.
salt	The raw salt bytes returned from Game Center (via GetSalt()). Required for modern Game Center verification.
teamPlayerId	Only required when gameCenterId is set to a value other than TeamPlayerId.
