title: Get numberOfRowsInSection from another UITableViewController XCode7 Swift2
body: <p>I've a CRUD scheme in a <code>TableViewController</code> (A) working fine (with only 1 section and several rows). So I want to implement another <code>TableViewController</code> (B) where the number of sections will be the number of rows of the first controller A.</p>
  
  <p>Here's the code of the controller B where I try to access <code>numberOfRowsInSection</code> from controller A (<code>AgrupamientosTableViewController</code>).</p>
  
  <pre><code>override func numberOfSectionsInTableView(tableView: UITableView) -&gt; Int {
      // #warning Incomplete implementation, return the number of sections
      return AgrupamientosTableViewController.tableView(tableView: UITableView, numberOfRowsInSection section: Int)
  }
  </code></pre>
  
  <p>I get the error: <code>Expected ',' as a separator</code>. </p>
  
  <p>Any idea? Thanks!</p>
