How to change Edit/Done button title in UINavigationBar in Swift : <p>I'm displaying an editButtonItem in my tableview but I need to change the text of Edit and Done to Change and Cancel. All the examples I've found so far are in Objective-C... I need Swift syntax.</p>

<p>I have the following in viewDidLoad function...</p>

<pre><code>self.navigationItem.leftBarButtonItem = self.editButtonItem()
</code></pre>

<p>... which displays the standard Edit/Done button item.</p>
