You can also do a push in your previous view controller in the method tableView:didSelectedRowAtIndexPath:

 func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {

  var newViewController = ..
  self.navigationController!.pushViewController(newViewController, animated: true)
 }

And it is done. The back button is already there.

The back buttons are created automatically on a push/segue. If you want to create this functionality yourself you would have to set the leftBarButtonItem property of the UINavigationItem and implement a method to call:

func backBTPressed() {
     self.navigationController.popViewControllerAnimated(yes)
}
