title: Xcode: Any way to refresh/re-run the playground?
body: <p>The Playground in Xcode automatically updates as you type, but I can't figure out how to get the Playground to "re-compile".</p>
  
  <p>In many cases this wouldn't matter, but if you're writing code that generates or uses random values it can be useful to run it a few times to make sure it's working. Is there any way to get the playground to reset / refresh / re-run?</p>
  
  <p>Seen a few questions asking how to stop the Playground from auto-updating, but nothing for the opposite.</p>
  
  <p>Easiest way to do this seems to be to just edit the code (add and remove a space), or put in some kind of a loop... Just wondering if there's a menu shortcut etc.</p>
