Add This line To your Project As a extension Your Problem is solved.

  extension UITextField{

        @IBInspectable var doneAccessory: Bool{
            get{
                return self.doneAccessory
            }
            set (hasDone) {
                if hasDone{
                    addDoneButtonOnKeyboard()
                }
            }
        }

        func addDoneButtonOnKeyboard()
        {
            let doneToolbar: UIToolbar = UIToolbar(frame: CGRect.init(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
            doneToolbar.barStyle = .default

            let flexSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
            let done: UIBarButtonItem = UIBarButtonItem(title: "Done", style: .done, target: self, action: #selector(self.doneButtonAction))

            let items = [flexSpace, done]
            doneToolbar.items = items
            doneToolbar.sizeToFit()

            self.inputAccessoryView = doneToolbar
        }

        @objc func doneButtonAction() {
            self.resignFirstResponder()
