Insets not respecting tabBarController height #75

Repost of #70

Is there any way to make MessageViewController respect the tabBar (if you have one?)

The only way I found for it to adjust for the tab bar is with
tabBarController?.tabBar.isHidden = true

However if you use something like (animatable)
tabBarController?.tabBar.frame.origin = CGPoint(x: 0, y: frameHeight - tabBarHeight)

The messageView will still show the extra 49pts of tabbarheight

As shown in the below photo, when I used
tabBarController?.tabBar.frame.origin = CGPoint(x: 0, y: frameHeight - tabBarHeight)

The message view is

135pt (34pt safe area + 49pt tab bar + [52pt messageView.textInputView])
when it should be
86pt (34pt safe area + [52pt messageView.textInputView])

To make it work temporarily I edited MessageViewController (which I know I shouldn't!)

internal var safeAreaAdditionalHeight: CGFloat {
        switch keyboardState {
            //EDITED
        case .hiding, .resigned: return view.util_safeAreaInsets.bottom - (49) //EDITED TO ACCOUNT FOR TABBAR
        case .showing, .visible: return 0
        }
    }
