title: How can I Quick Look custom objects with Xcode 5 visual debugger?
body: <p>Xcode 5 has a great new feature where you can hover over a variable name and get a visual representation of a UIColor, UIImage, or even UIBezierPath. </p>
  
  <p>I vaguely remember a comment at WWDC where developers could either conform to some protocol or override some methods on any NSObject subclass in order to participate in this new debugging feature. I would love to add this to a bunch of my model objects to help me debug. Anyone know whether this is a real thing yet, or even if they hinted at it in a future release?</p>
  
  <p>Unfortunately, Apple refers to this feature as "Quick Look" and since they have another technology called "Quick Look" my search results are very noisy and I can't find anything helpful.</p>
