title: Open view controller programatically and dont see navigation bar. Swift 3
body: <p>On my story board I have a collection view controller embedded in a navigation controller. Now from the cell of the collection view, I programaticly open the second view controller (called TwoPicsViewController), like this:</p>
  
  <pre><code> let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
  
              let nextViewController = storyBoard.instantiateViewController(withIdentifier: "TwoPicsViewController") as! TwoPicsViewController
  
  
              self.present(nextViewController, animated:true, completion:nil)
  </code></pre>
  
  <p>However when my TwoPicsViewController opens, I don't see the navigation bar at all. On the story board I connected the TwoPicsViewController to the first view controller with a segue show.</p>
  
  <p>Am I missing something else?</p>
  
  <p>Thanks</p>
