title: Storyboard in Xcode is so slow
body: <p>I have 150 UIViewController in Storyboard and scrolling between these Views is so slow. I can't zoom in and zoom out easily and it takes some serious time to do sty.</p>
  
  <p>I'm on MBPR and I installed Xcode 4.4</p>
  
  <p>Spec: 2.3GHz / 16G / 256 which I think it's enough to handle such a thing. </p>
  
  <p>Is there any options, settings, or tips/tricks to have so many views in storyboard and don't miss the performance.</p>
  
  <p>NOTE: I've done all the possible solutions (deleting cache and workspace). Didn't work. It has something to do with number of UIViewController in Storyboard.</p>
  
  <p>Thanks</p>
  
  <p><strong>Update 2016</strong>: Just to update this question as there is a new feature in Xcode 7 that allows you to refactor the Storyboard into multiple Storyboards.</p>
