title: iOS Swift 1.2: How to set a unique identifier for each cell aside from indexPath.row
body: <p>I'm building an iOS app that has <code>Post</code> objects (like FB posts), and each one is displayed by a <code>UITableViewCell</code>. I'm trying to implement the ability to delete that post using the built in <code>tableView(commitEditingStyle)</code> method of the <code>UITableViewController</code>.</p>
  
  <p>Temporarily I've been using the <code>indexPath.row</code> as the key for which post to delete, but obviously that will not work in the long run.</p>
  
  <p>Is there a way to set some sort of unique identifier for each individual cell, ideally an integer equaling the index of the <code>Post</code> it contains?</p>
  
  <p>Essentially I'm trying to create a One-to-One relationship with each <code>UITableViewCell</code> and its containing <code>Post</code>.</p>
