How to hide keyboard on return key in Sprite kit?

I'm using UITextField for user to enter his name. And this is how I add UITextField to the game.

let firstPlayer:UITextField = UITextField()
firstPlayer.frame = CGRect(origin: CGPoint(x: (self.scene?.size.width)! * 0.21, y: (self.scene?.size.height)! * 0.2), size: CGSize(width: 200, height: 30))
firstPlayer.placeholder = "First Player Name"
firstPlayer.backgroundColor = UIColor.lightGray
firstPlayer.autocorrectionType = UITextAutocorrectionType.no
firstPlayer.keyboardType = UIKeyboardType.default
firstPlayer.keyboardAppearance = UIKeyboardAppearance.default
firstPlayer.delegate = self as? UITextFieldDelegate
firstPlayer.isHidden = true
view.addSubview(firstPlayer)

later i unhide the textfield before it's needed. when I press on textfield in simulator the keyboard pops up. But when I press Return nothing happens.

I searched about this for sprite kit but found everything about uikit. I tried adding 

    func textFieldShouldReturn(_textField: UITextField) -> Bool {
      self.view.endEditing(true);   // or resignFirstResponder
      return false;
    }

to the GameViewController or in it's viewDidLoad or willLayoutSubviews but nothing worked. I can't understand how it would be done in sprite kit.

Any Help will be really Appreciated Thanks.

The line:

firstPlayer.delegate = self as? UITextFieldDelegate

should just be:

firstPlayer.delegate = self

The fact that you added the as? UITextFieldDelegate probably means that you forgot to indicate that your class conforms to UITextFieldDelegate.

Update your class declaration from something like:

class MyViewController: UIViewController {

to something like:

class MyViewController: UIViewController, UITextFieldDelegate {

Just add the , UITextFieldDelegate to whatever your current declaration is.

You also have a typo on:

func textFieldShouldReturn(_textField: UITextField) -> Bool {

That needs to be:

func textFieldShouldReturn(_ textField: UITextField) -> Bool {

Note the space after the _.
