How to use CoreData in Xcode 8?
<p>I am trying use CoreData, but when I add it to my project I only get two new methods :</p>

<pre><code>- (NSPersistentContainer *)persistentContainer
</code></pre>

<p>and </p>

<pre><code>- (void)saveContext
</code></pre>

<p>Now I can't get old methods to work with <code>CoreData</code>, and I can't find any tutorials with these new methods and Objective-C. How can I save and get data from <code>CoreData</code> using <code>persistentContainer</code> in Xcode 8 with Objective-c?</p>
