Move view up when keyboard shows, for textfield in a stackview

I have a scenario were i move the view up when the keyboard appears, this scenario works fine however as soon as i start typing the view goes back to its original position. Something to note is that the textfield is in a stackview.

My question is that is there a way i can stop the view from going back to its original position when textEditing begins.

This is my code : 

override func viewDidLoad() {

    super.viewDidLoad()

    NotificationCenter.default.addObserver(self, selector:#selector(self.keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
    NotificationCenter.default.addObserver(self, selector:#selector(self.keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

 var isScroll = false


@objc func keyboardWillShow(sender: NSNotification) {
    mainView.frame.origin.y = -100
}
@objc func keyboardWillHide(sender: NSNotification) {
    mainView.frame.origin.y = 0
}

add a scrollview as your base view and inside this add your contentview then 

func keyboardShown(_ notification: Notification){

    var userInfo        = notification.userInfo!
    let keyboardSize    = (userInfo[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue
    let contentInsets   = UIEdgeInsetsMake(0.0, 0.0, (keyboardSize!.height + 40), 0.0)
    self.mainScrollView.contentInset            = contentInsets
    self.mainScrollView.scrollIndicatorInsets   = contentInsets



    // **-- Scroll when keyboard shows up
    let aRect           = self.view.frame
    self.mainScrollView.contentSize = aRect.size

    /* if((self.activeTextField) != nil)
     {
     self.scrollView.scrollRectToVisible(self.activeTextField!.frame, animated: true)
     }*/

}

func keyboardHidden(_ notification: Notification) {

    let contentInsets   = UIEdgeInsets.zero
    self.mainScrollView.contentInset            = contentInsets
    self.mainScrollView.scrollIndicatorInsets   = contentInsets

    // **-- Scroll when keyboard shows up
    self.mainScrollView.contentSize = self.containerView.frame.size
}

My personal opinion to use this library else you can manage the whole UI into the UITableview so no need to manage keyboardWillShow and keyboardWillHide method in that controller.
