title: How to get height of UITableView when cells are dynamically sized?
body: <p>I have a UITableView with cells that are dynamically sized. That means I have set:</p>
  
  <pre><code>tableView.estimatedRowHeight = 50.0
  tableView.rowHeight = UITableViewAutomaticDimension
  </code></pre>
  
  <p>Now I want to get the height of the whole table view. I tried getting it through <code>tableView.contentSize.height</code> but that only returns the estimated row height, and not the actual dynamic height of the table view.</p>
  
  <p>How do I get the dynamic height of the whole table view?</p>
