title: Xcode 6 Interface Builder "cannot open compiled nibs" error, FiksuSDK
body: <p>I have an app that runs great in Xcode 5, using CocoaPods.</p>
  
  <p>When I open the app on Xcode 6 and hit build and run, I get four errors from the FiksuSDK about compiled nib files. </p>
  
  <p>On the side, it states that I do not have permission to view it, but tapping on it shows the error: "The document "FMVerifyViewController.nib" could not be opened. Interface Builder cannot open compiled nibs." I don't directly call any of these nib files, however it's possible that the Facebook API does.</p>
  
  <p>Screenshots attached.</p>
  
  <p>I've tried removing the Pods directory, deleting derived data, updating pods and restarting Xcode. Nothing.</p>
  
  <p>Any help would be really appreciated.</p>
