I change the view size depend on keyboard is open or close.

Answer 1

Try this to remove keyboard open show observers,

NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillShow, object: nil)
NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillHide, object: nil)

you should remove observers either in deinit Or viewDidDisappear as per your requirement.
