title: UISplitView with preferredDisplayMode primaryOverlay covers entire screen and overlaps UITabbar
body: <p>I am trying to use UISplitView in UITabBar. I want master(left side view) splitview to act as a Slide Menu for which I have set splitview property preferredDisplayMode 'primaryOverlay' which can overlay detail screen and goes back on selecting item from menu. </p>
  
  <p>But here the master view covers the entire screen including UITabbar. Can we have any solution that can just overlay the screen above UITabBar so that TabBar remains accessible?</p>
  
  <p>Attaching the screenshot for clear idea..</p>
