I develop some app to iPad and iPhone, but I have a problem with a gray bar up to the TabBar.
I have tried extendedLayoutIncludesOpaqueBars = true
but it didn't work. It works on iPad, but when I use SplitView the problem comes. Gray bottom view on the Screen. I have this problem on my iPhone, when I push view like that
splitViewController?.showDetailViewController(UINavigationController(rootViewController: controller), sender: nil)
On iPad it works when I use split view full screen: Great size
But when I resize SplitView it breaks: Gray bottom view
Problem solved. I change constraints when traitcollectiondidchanged.
