title: iPhone X Launch Screen Storyboard Align UITabBar to Bottom
body: <p>I am updating my LaunchScreen.storyboard for the iPhone X (using Xcode 9.1) but cannot get the UITabBar to align to the absolute bottom. The Bottom Layout Guide seems to end at the safe area using the suggested constraints. Does anyone know what property or constraint I need to add?</p>
  
  <p>Note that I am deliberately using a UIViewController with a UITabBar instead of a UITabBarController because I do not want any tabs selected by default and this seems to be the only workaround.</p>
