title: How do you add entities to a Sprite Kit scene using the Xcode Sprite Kit scene editor?
body: <p>According to the Sprite Kit documentation for entities and components</p>
  
  <blockquote>
    <p>When you add entities (and their components) to a scene in the Xcode SpriteKit Scene Editor, Xcode automatically archive those entities alongside the SpriteKit scene content.</p>
  </blockquote>
  
  <p>This implies that you can add entities using the scene editor, but I can't find any way to do that. I can add components using the node components inspector, but not entities. How is this done?</p>
