title: Push view controller when cell is tapped
body: <p>I have tableViewController which pulls data from Parse. This calls inherits from UINavigationControllerDelegate.</p>
  
  <p>I want to push a new view controller when the user taps on a cell. It seems like a simple task but I can't get it to work. I have first tried just simply making a push segue in my storyboard but nothing happens when I tap on the cell. I have tried to do it programmatically but the app crashes when I tap on the cell. I get a breakpoint error on the instantiation line:</p>
  
  <pre><code>import UIKit
  import Foundation
  import Parse
  
  
  class PFViewController: PFQueryTableViewController, UITableViewDataSource, UINavigationControllerDelegate {
  
  override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
      let vc: Podcast = self.storyboard?.instantiateViewControllerWithIdentifier("Podcast") as Podcast
      self.navigationController?.pushViewController(vc, animated: true)
   }
  }
  </code></pre>
  
  <p>Any ideas please?</p>
