Well, that's a simple problem to solve.. UsernameTextField.text and PasswordTextField.text can be blank, so you can't put ! after it.. You have to do something like this:

if UsernameTextField.text != nil && PasswordTextField != nil { user.username = UsernameTextField.text user.password = PasswordTextField.text }

Hope this helps..
