Эта ошибка sh происходит в UINavigationController три раза (присутствует и отклоняется, соответственно, 2 раза после первого открытия).
Я выполнил отладку с помощью точек останова и решил, что это происходит в представленном ViewController после viewWillAppear fini sh и перед viewWillLayoutSubviews.
Однако он не остановился между моими строками кода, поэтому я не могу определить причину ошибки.
происходит ТОЛЬКО в IOS 12 (отлично работает в IOS 13)
