Not returning a function when return key is pressed on Keyboard

Question

I'm having some trouble running a function after the return key is pressed on keyboard. I'm trying to get the keyboard to be dismissed when the return key is pressed but I found that the function is not being run at all. If anybody could please take a look I'd greatly appreciate it. Thanks!

class ViewController: UIViewController, UITextFieldDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        addWelcomeLabel()
        print("view running")
        self.nameRequestField.delegate = self
    }

    let nameRequestField = UITextField(frame: CGRect(x: 0, y: 0, width: 330, height: 40))
    func textFieldShouldReturn(textField: UITextField) -> Bool {
      //nameRequestField.resignFirstResponder()
        print("hello")
        return true
    }
}

`func textFieldShouldReturn(textField: UITextField) -> Bool {` should be `func textFieldShouldReturn(_ textField: UITextField) -> Bool {` — MadProgrammer, Mar 12 '20 at 03:21

You can use this method

func textFieldShouldReturn(textField: UITextField) -> Bool {
        nameRequestField.resignFirstResponder()
        return true
}

This code snippet does not resolve the question. Additionally, it has no functional difference with the snippet provided by the person asking. Also, please fix the indentation. – Isaaс Weisberg Mar 12 '20 at 07:02
