Seems like there is a confirmed bug on Xcode12 + iOS14.
I have a UINavigationController on each item of a UITabBar, and I've set hidesBottomBarWhenPushed to YES on every secondary ViewControllers, so the TabBar will only be shown on the rootViewController of navigationController. But when I try popping multiple ViewControllers, like pop C from stacks like A-B-C, I found that the TabBar just missing on A.
Also another weird part, when I print navigationController.viewControllers in viewWillDisappear: method on C, I found it printing like "C-A". How C moved to the top of the array??
This is confirmed on a simple demo app, wonder when it will be fixed.
