title: Safe Area Guide Not Appearing in Xcode
body: <p>I use XIB in most of my apps instead of Storyboards.  As you can see from the picture, I have Safe Area Layout Guide enabled as well as Auto Layout, but for some reason, my XIB still shows top and bottom layout guide instead of safe area.  What am I missing?  Ok, I changed to update recommended settings.  It still doesn't show Safe Area in the XIB file, but the app itself does seem to be respecting safe area.  Does this like the proper way this is supposed to be done?</p>
