What's the height of a UITabBar on iOS 8, iOS 9, iOS 10, and iOS 11?

Question

The height of the UITabBar seems to have changed between iOS 7 and 8/9/10/11. I\'m posting this question for others to easily find the answer.

So: What\'s the height

Answer 1

I would recommend just calculating it using TabBar.Height - UIApplication.SharedApplication.KeyWindow.SafeAreaInsets.Bottom. Check for system version >= 11 first.
