iOS 11 extra space between keyboard and accessoryView

Question

I have some weird UI bug with inputAccessoryView and keyboard. Code to add inputAccessoryView in viewDidLoad

        let keyboardToolbar = UIToolbar()
    keyboardToolbar.items = [
        UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil),
        UIBarButtonItem(title: "Hide", style: .done, target: self, action: #selector(resignFirstResponder))
    ]

    keyboardToolbar.barStyle = barStyle
    keyboardToolbar.sizeToFit()

    myTextfield.inputAccessoryView = keyboardToolbar

First time entering screen and tap to textfield works good. After closing this screen (popViewController) and entering it again and get focus to textField I've got this: UIToolBar is above keyboard. Empty space have height = keyboard height

Try specifying the frame for your `UIToolBar`: `let keyboardToolbar = UIToolbar(frame: CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 40))` — rbaldwin, May 06 '18 at 20:36
Doesn't help. Also tried replace UIToolBar with custom UIView - same bug — Mikhail Serov, May 06 '18 at 21:42
have you implemented this function your self [resignFirstResponder]? — Awais Fayyaz, May 08 '18 at 05:04

Some different problem in my case because first time keyboard appears all look fine. And after a bug caused toolbar's button 'Hide' is located there it is supposed to be so I can tap on empty space above keyboard and Hide calls. Looks like just UI render problem – Mikhail Serov May 06 '18 at 20:59
What code? I've tried layoutIfNeeded() and setNeedsDisplay(). Doesn't help – Mikhail Serov May 06 '18 at 21:38
where you add this code in Viewdidload , previous code work with me without any error – Abdelahad Darwish May 06 '18 at 21:39
I have many elements, few animation in screen's lifecycle and reactive (rxswift) on textField. So I'll guess this is not a common bug. – Mikhail Serov May 06 '18 at 21:57
May be try it alone make sure it not constrained – Abdelahad Darwish May 06 '18 at 21:58

I do not know the reason but workaround is to call either

view.endEditing

or

textField.resignFirstResponder()

in

viewWillDisappear
