The @c NSLocalizedFailureReasonErrorKey field in the @c NSError.userInfo dictionary will contain more information about the error encountered" UserInfo={NSLocalizedDescription=An error occurred when accessing the keychain. The @c NSLocalizedFailureReasonErrorKey field in the @c NSError.userInfo dictionary will contain more information about the error encountered, error_name=ERROR_KEYCHAIN_ERROR, NSLocalizedFailureReason=SecItemAdd (-34018)})

firuser : nil
FIRAuth.auth()?.currentUser?.uid : nil
firuser?.uid : nil

server user added :

What gives you nil? The firuser? The error? Is there an error? Is email and pass valid? Please don't use 'return' in Firebase closures as they are not needed and errors should be handled more elegantly. Please update and clarify the question so we can help. — Jay
