Make the textfiled swipe up when keyboard is used swift 5

Question

I'm trying to make the text field txtAdd swipe up when the keyboard shows up, but I'm not really sure how to do it.

This is the code for adding items to the list:

@IBAction func submitBntFunc(_ sender: Any) {
    if let text = txtAdd.text{
             if text == ""{
                 return
             }
             txtAdd.text = ""
             txtAdd.resignFirstResponder()
        return txtField.text.append("\(text) \n")

         }

}

I tried with the code below but it didn't really work.

guard let keyboardSize = userInfo[UIKeyboardFrameEndUserInfoKey] as? NSValue else {return}

try with this code

var originButton : CGFloat?

override func viewDidLoad()
{
     originButton = self.YOURBUTTON.frame.origin.y
     NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)
     NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name: UIResponder.keyboardWillHideNotification, object: nil)

}

@objc func keyboardWillShow(notification: NSNotification) {
    if let keyboard = ((notification.userInfo?[UIResponder.keyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue) {
        if self.view.frame.origin.y == 0 {
            self.YOURBUTTON.frame.origin.y -= keyboard.height

        }
    }
}

@objc func keyboardWillHide(notification: NSNotification) {
    if self.YOURBUTTON.frame.origin.y != originButton {
        self.YOURBUTTON.frame.origin.y = originButton!
    }
}

it seems like its only the button that swipes up and not the "txtAdd" filed... – Alison Dec 02 '19 at 19:21
I added this line ` self.txtAdd.frame.origin.y -= keyboard.height ` but then it swipes up all the way to the top – Alison Dec 02 '19 at 19:23
And the txtAdd keeps swiping up every time that I click on the screen – Alison Dec 02 '19 at 19:25
are you using constrains? add this line ´self.view.layoutIfNeeded()´ – Andres Gomez Dec 02 '19 at 19:26

add this Observer in your viewDidLoad methods:=

    NotificationCenter.default.addObserver(self, selector: #selector(keyboard), name: UIResponder.keyboardWillHideNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboard), name: UIResponder.keyboardWillChangeFrameNotification, object: nil)

And it is call this function:=

    @objc func keyboard(notification: Notification){
    let userInfo = notification.userInfo!
    let keyboardScreenEndFrame = (userInfo[UIResponder.keyboardFrameEndUserInfoKey] as! NSValue).cgRectValue
    let keyboardViewEndFrame = view.convert(keyboardScreenEndFrame, to: view.window)

    if notification.name == UIResponder.keyboardWillHideNotification{
        //add your constrain here when keyboard is hiden
        self.scrollView.contentInset = UIEdgeInsets.zero
    }else{
        //add your constrain here when keyboard is visible
        self.scrollView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: keyboardViewEndFrame.height, right: 0)
    }
    scrollView.scrollIndicatorInsets = scrollView.contentInset
}
