title: viewWillAppear is not being called when using Modal Segue
body: <p>I have a <strong>Table View Controller</strong> and a <strong>Modal segue</strong> to which I can add to the data which is populating the <code>UITableView</code>. My code went from working to not working because the <code>viewWillAppear</code> is now not being called when closing the modal view, therefore the table view is not repopulating the table with new data. </p>
  
  <pre><code>override func viewWillAppear(animated: Bool) {
      super.viewWillAppear(animated);
  
      self.tableView.reloadData()
      println("View Will Load was called")
  } 
  </code></pre>
  
  <p>I even added the following code when closing the modal view. </p>
  
  <pre><code> self.presentingViewController!.viewWillAppear(true)
  </code></pre>
  
  <p>Does anybody know why this may be happening. Like I already mentioned it was working fine and can not figure out why it has stopped working now. </p>
