title: Not able to assign custom viewcontroller in storyboard
body: <p>I am absolutely clueless what happened to Xcode. I'm not even able to assign a custom ViewController to a storyboard ViewController. I get the error: </p>
  
  <p>"Unknown class vcTest in Interface Builder file...........
  this class is not key value coding-compliant for the key label" </p>
  
  <p>vcTest is my custom ViewController. I saw several solutions to this in other posts but my problem seems to be a lot different.</p>
  
  <p>In this test app, I have 1 ViewController:</p>
  
  <pre><code>import Foundation
  import UIKit
  
  class vcTest: UIViewController {
  
      @IBOutlet weak var label: UILabel!
  
  
  }
  </code></pre>
  
  <p>The only ViewController in the storyboard is assigned to this ViewController, having 1 label outlet. vcTest does show up under: Build Phases -> Compile Sources. I must be totally missing something here or Xcode is absolutely broken. I even tried to uninstall and reinstall Xcode which did not help.... I have an other ungoing project were I discovered this issue and now it even comes up in this simple test app. What is going on here? </p>
  
  <p>Note: this happened after upgranding from Yosmite 10.10 to 10.10.1.</p>
  
  <p>edit:
  so this is what i found out til now:
  i somehow created one project where this does not happen, on all other projects it does. it did not specify anything special in the working project. what i noticed between the working and "codewise similar" non working is the module listed in storyboard. the working one shows : Current - projectname and the none working one shows None. i attached a screenshot. 
  how can i change the model to current model?
