  I created a new single view project, imported my framework and  tried to load my framework viewcontroller, but i got black screen. And I dont know why.</p>
  
  <p>I tried load framework with this code:</p>
  
  <pre><code>let frameworkScreen : UIViewController = MainViewController()
      self.presentViewController(frameworkScreen, animated: true, completion: nil)
  </code></pre>
