Answer 1

Swift 5.0 :- Drag your UITextView in a contentView(UIView), Create IBOutlet of bottom constraint of contentView i.e bottomConstraint. After use the below code as mentioned and custom NavigationBar will also stick at top only textView will be just above keyboard.
override func viewDidLoad() {
super.viewDidLoad()
let center: NotificationCenter = NotificationCenter.default
center.addObserver(self, selector: #selector(Profile.keyboardWillShow(notification:)), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
center.addObserver(self, selector: #selector(Profile.keyboardWillHide(notification:)), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}
#objc func keyboardWillShow(notification: NSNotification){
let userInfo:NSDictionary = notification.userInfo! as NSDictionary
let keyboardSizeNow:CGSize = (userInfo.object(forKey: UIKeyboardFrameEndUserInfoKey)! as AnyObject).cgRectValue.size
UIView.animate(withDuration: 0.2, animations: { () -> Void in
self.bottomConstraint.constant = keyboardSizeNow.height - 49
self.view.layoutIfNeeded()
})
}
#objc func keyboardWillHide(notification: NSNotification){
UIView.animate(withDuration: 0.2, animations: { () -> Void in
self.bottomConstraint.constant = 0
self.view.layoutIfNeeded()
})
}

you can implement keyboardWillShow and keyboardWillHide method in similar way
func keyboardWillShow(notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
buttonBottomConstraint.constant = keyboardSize.height
UIView.animate(withDuration: 0.3, animations: {
self.view.layoutIfNeeded()
})
}
}
func keyboardWillHide(notification: NSNotification) {
if let _ = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
bottomConstraint.constant = 0
UIView.animate(withDuration: 0.3, animations: {
self.view.layoutIfNeeded()
})
}
}
also, don't forget to observe in viewDidLoad.
