Swift: InputaccessoryView не активируется (iPhone X)

Question

У меня есть пользовательский вид для inputaccessoryview, который прекрасно работает на всех устройствах, кроме iPhone X. Он даже отображается правильно, так как я использую safeAreaLayoutGuide.

Однако я не могу щелкать по кнопкам и текстовому полю (когда клавиатура скрыта, поэтому, когда представление ввода находится внизу) только в последнем горизонтальном ряду пикселей внизу и когда клавиатура действительно отображается.

Кто-нибудь знает, где моя ошибка?

Просмотр настроек в пользовательском представлении (клавиатура):

    if #available(iOS 11.0, *){

        self.insetsLayoutMarginsFromSafeArea = true
