title: UINavigationController Push Segue - Strange animation
body: <p>I have a UINavigationController which was created in Storyboards, and connected with push segues for each view controller. However, when I click "next" (which activates the push segue), then animation going forward is strange. (See: <a href="https://www.youtube.com/watch?v=0cFo9sUtBeM" rel="nofollow">https://www.youtube.com/watch?v=0cFo9sUtBeM</a>). Going back (Selecting the root controller of the UINavController in the UITabBarController) has the correct animation though. Any ideas why this could be?</p>
  
  <p><strong>Edit</strong>: the boxes in the video are added by me to protect client identity. The animation issue detailed is the slide animation which appears to come from the top right (or top left for the 'next' button).</p>
