title: Exception: terminate called throwing an exceptionsharedlibrary apply-load-rules all
body: <p>I am trying to pull a VC xib, by adding the view of controller on window's view. When I execute the program nothing appears (a black screen), and expectation was a button put on view of VC in xib. 
  But when I declare that this VC is my Project's main interface (Project Summary), then it throws the exception : terminate called throwing an exceptionsharedlibrary apply-load-rules all and application crashes.</p>
  
  <p>Here is the code for didfinishlaunch (Appdelegate)</p>
  
  <pre><code>[self.window addSubview:rootViewController.view];
  [self.window makeKeyAndVisible];
  </code></pre>
  
  <p>Can somebody assist on that.</p>
  
  <p>Thanks</p>
  
  <p>PS: the complete error is given below</p>
