title: Switch to Xcode 8 beta?
body: <p>I'm running Xcode 7.3.1 on a MBP with OS X 10.11.3.</p>
  
  <p>I started using UIStackViews to help me lay out my UI. The first experiment went fine--made a great custom number pad with it. So I moved to a slightly more complex scene, and once I started nesting stack views, Xcode slowed to a crawl. With every command, it waits 5 seconds, then beachballs for 10 before executing it. Infuriating. I've restarted Xcode multiple times, but no improvement. And I see a number of people have reported this bug to Apple.</p>
  
  <p>I see the beta for Xcode 8 is available, and have read a few comments, but haven't found any directly relating to an improvement in the performance of stack views.</p>
  
  <p>Can anyone recommend the beta as a better choice than my current version based on their experience with stack view performance in Xcode 8 beta?</p>
