title: XCode 8 Beta Documentation Generation
body: <p>I'm currently exploring the latest Xcode Beta, and while doing so I'm watching some related WWDC videos. According to <a href="https://developer.apple.com/videos/play/wwdc2016/102/" rel="nofollow">this one</a>(around 33rd minute) you can now have a quick code generation macro(similar to Eclipse and AS). </p>
  
  <p>I'm unable to understand how to use this. Right after this we have a talk about xcode extension so it is possible this to be an extension however it's not clear to me - is it possible to have such feature with Xcode 8 beta?</p>
