title: How do you create an iOS liveView in Xcode 8/Swift 3
body: <p>I can't figure out how to create and display a live view in an Xcode 8/Swift 3 Playground. If Apple has comprehensive documentation on playgrounds and live views,  I can't find it, and all my searching online reveals either tutorials on Xcode 7 or the new iPad playgrounds. The few examples I have found set up Mac OS views, which is not what I want (I work mostly in iOS, so the code I want to test out is iOS code, dealing with iOS view hierarchies.)</p>
  
  <p>Can somebody give me the bare minimum setup to create a live view and install views into it from an Xcode 8 playground?</p>
  
  <p>Then, can somebody point me to some good documentation on playgrounds, and how you configure and use them?</p>
