title: Xcode assistant editor won't show some of the code
body: <p>First of all, I would like you to know that the class IS set to the correct file in each <code>ViewController</code> - I know that because it did work before, but then I got a "crash" in Xcode that blinked quickly without me being able to read it before it went off again.</p>
  
  <p><strong>MY PROBLEM IS</strong>:</p>
  
  <p>I have a lot of <code>ViewControllers</code> in my Xcode, everything was working fine, I was making some more features to the <code>ViewControllers</code>. </p>
  
  <p>Then I got the "crash" as mentioned above, and it would not show any of the files/classes related to their <code>ViewController</code> in assistant editor. </p>
  
  <p>Assistant editor just said: No Assistant Results. Then I read that I could just show the files inside my XCode project and delete <code>project.xcworkplace</code> and xcuserdata. And I thought it worked at first, but it did not work on every viewcontroller unfortunately - only on some of them. </p>
  
  <p>Now, I still have plenty of <code>ViewControllers</code> left to edit that aren't working, and I would hate if I had to recreate every single one.</p>
  
  <p>Does anyone have a better solution to this? I really hope you do :-)</p>
