Swift 4.2 :

Other approach for the textfield created programmatically and doesn't need delegate :

     MyTextField.addTarget(self, action: #selector(MyTextFielAction)
                               , for: UIControl.Event.primaryActionTriggered)

And then perform your action like below :

    func MyTextFielAction(textField: UITextField) {
       //YOUR CODE can perform same action as your UIButton
    }
