title: Pop to root view controller from modal
body: <p>I am trying to pop to the root view controller using the following code:</p>
  
  <pre><code>self.navigationController!.popToRootViewController(animated: true)
  </code></pre>
  
  <p>This usually works, but I get an error when trying to use this code when the current view is a modal. How do I go about popping back to the root view controller in this situation?</p>
  
  <p>Thanks in advance.</p>
