title: Using SceneKit in Swift Playground
body: <p>I've looked everywhere for this but I'm coming up blank. How do you replicate what Chris Lattner was demonstrating with Playgrounds and SceneKit at WWDC? I want to have a SceneKit scene, animating, in Playgrounds.</p>
  
  <p>I tried cutting and pasting the setup code from the SceneKit project template, thinking it would magically start rendering, but it does not.</p>
  
  <p>I tried watching the keynote and pausing and zooming on on Lattner's screen looking for hints at the source code, but he appeared to be importing all his code from elsewhere in his project, so it gave me no clues. There does not seem to be anything in the documentation, or I'm missing it.</p>
