Keeping object on top of keyboard in the event of becomeFirstResponder or resignFirstResponder?

Question

I currently have a UITextField on top of a keyboard. When you tap it, it should stick on top of the keyboard and move up smoothly. I don\'t know the exact duration and anima

Use this code in your keyboard notification:

@objc func keyboardWillShowNotification(notification: Notification) {
    let keyboardHeight = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue.size.height ?? 216
    let duration = notification.userInfo?[UIKeyboardAnimationDurationUserInfoKey] as? Double ?? 0.25
    let curve = (notification.userInfo?[UIKeyboardAnimationCurveUserInfoKey] as? UInt ?? 7) << 16
    tableViewBottomConstraint.constant = keyboardHeight - submitButtonContainer.frame.size.height

    UIView.animate(withDuration: duration, delay: 0, options: [UIViewAnimationOptions(rawValue: curve)], animations: {
        // Animation
    }, completion: nil)
}
