title: Segue out of parent navigation view controller from embedded table view controller
body: <p>I have a table view controller embedded in a navigation view controller using <code>Editor &gt; Embed In &gt; Navigation Controller</code></p>
  
  <p>Doing that didn't create a Swift file for the Navigation Controller so I created one and assigned the Navigation Controller to that class on the Storyboard.</p>
  
  <p>So I use the Navigation Controller to provide a bottom toolbar (no top navbar shown) to the Table View Controller. On that toolbar, I have buttons that link to other views--views which should not be embedded in the Navigation Controller. </p>
  
  <p>But when I do a basic "Show" segue from my embedded Table View Controller to, for instance, Main Menu controller, we arrive at the Main Menu controller which is now embedded in the Navigation Controller. </p>
  
  <p>I want to segue out of the Navigation controller from its embedded Table View Controller to an unrelated third party.</p>
  
  <p>I've tried using <code>self.parentViewController</code> and <code>self.topViewController</code> in my <code>performSegueWithIdentifier</code> function but those properties aren't found under <code>self</code>. </p>
  
  <p>I'm using xcode 7.3.1 (Swift 2). </p>
