button.adjustsImageWhenHighlighted = false
button.addTarget(self, action: #selector(ViewController.Done(_:)), for: UIControlEvents.touchUpInside)
Step 7 : The delegate of textFieldDidBeginEditing adding notification to open KeyBoard code.

        self.button.isHidden = false
        let keyBoardWindow =
        self.button.frame = CGRect(x: 0, y: (keyBoardWindow?.frame.size.height)!-53, width: 106, height: 53)
        keyBoardWindow?.bringSubview(toFront: self.button)
        UIView.animate(withDuration: (((note.userInfo! as NSDictionary).object(forKey: UIKeyboardAnimationCurveUserInfoKey) as AnyObject).doubleValue)!, delay: 0, options: UIViewAnimationOptions.curveEaseIn, animations: { () -> Void in

  1. Change this to adjust the x coordinates of the return button in all devices :
    let doneButtonXCoordinates = (keyBoardWindow?.frame.size.width)! * CGFloat(0.33125)
    self.button.frame = CGRectMake(0, (keyBoardWindow?.frame.size.height)!-53, doneButtonXCoordinates, 53)

  2. Very Helpful tutorial. Thank You Kirit.
