title: UITableViewAutomaticDimension not working until scroll
body: <p>When the Table View is first loaded, all of the visible cells are the estimatedRowHeight. As I scroll down, the cells are being automatically sized properly, and when I scroll back up the cells that were initially estimatedRowHeight are being automatically sized properly.</p>
  
  <p>Once the cells are being automatically sized, they don't ever seem to go back to being the estimatedRowHeight.</p>
  
  <pre><code>override func viewDidLoad() {
      super.viewDidLoad()
      self.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: .Plain, target: nil, action: nil)
      self.tableView.estimatedRowHeight = 80.0
      self.tableView.rowHeight = UITableViewAutomaticDimension
  
      // Uncomment the following line to preserve selection between presentations
      // self.clearsSelectionOnViewWillAppear = false
  
      // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
      // self.navigationItem.rightBarButtonItem = self.editButtonItem()
  }
  </code></pre>
  
  <p>and</p>
  
  <pre><code>    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -&gt; UITableViewCell {
  
      let cellIdentifier = "Cell"
      let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as CustomTableViewCell
  
      // Configure the cell...
      let restaurant = restaurants[indexPath.row]
      cell.namelabel.text = restaurant.name
      cell.locationlabel.text = restaurant.location
      cell.typelabel.text = restaurant.type
      cell.thumbnailImageView.image = UIImage(named: restaurant.image)
      cell.thumbnailImageView.layer.cornerRadius = cell.thumbnailImageView.frame.size.width / 2
      cell.thumbnailImageView.clipsToBounds = true
      cell.accessoryType = restaurant.isVisited ? .Checkmark : .None
  
      return cell
  }
  </code></pre>
  
  <p>Thoughts on how to have the cells autoresize initially?</p>
  
  <p><strong>UPDATE:</strong> As of Xcode 7 beta 6 this is no longer an issue</p>
