Question

Answer 1

The selected answer is incomplete and produce compilers error,

Cannot invoke 'addObserver' with an argument list of type '(RegistrationViewController, selector: Selector, name: NSNotification.Name)'

Here is the working format,

NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillChange(notification:)), name: UIResponder.keyboardWillShowNotification, object: nil)
