Retrieving user information
Once the user has authenticated and authorized access to the scopes you request,

- (void)signIn:(GIDSignIn *)signIn
didSignInForUser:(GIDGoogleUser *)user
withError:(NSError *)error {
if (error != nil) {
if (error.code == kGIDSignInErrorCodeHasNoAuthInKeychain) {
NSLog(@"The user has not signed in before or they have since signed out.");
} else {
NSLog(@"%@", error.localizedDescription);
}
return;
}
// Perform any operations on signed in user here.
NSString *userId = user.userID; // For client-side use only!

NSString *fullName = user.profile.name;
NSString *givenName = user.profile.givenName;
NSString *familyName = user.profile.familyName;
NSString *email = user.profile.email;
