TextField not moving

This is my keyboardWillShow function on the newest version of swift and XCode.

@objc func keyboardWillShow(_ notification: Notification) { if let info = notification.userInfo, let keyboardFrame = info[UIResponder.keyboardIsLocalUserInfoKey] as? NSValue { let frame = keyboardFrame.cgRectValue textFieldConstraint.constant = frame.size.height + 20 print(textFieldConstraint.constant) } }

My textfield doesn't move. When I print the textFieldConstraint.constant the terminal prints 20.0. The frame.height is set to 0. Anyone have any idea

This is my version for your reference

@objc func keyboardWillShow (_ notification: Notification) {
        if let info = notification.userInfo, let keyboardFrame = info[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue {
            let frame = keyboardFrame.cgRectValue
            textFieldButtomConstraint.constant = frame.size.height + 10
        }
    }
