title: How do I read Core Data descriptions?
body: <p>I'm having trouble debugging core data. I have two objects</p>
  
  <pre><code>&lt;MyClass: 0x7f9eab6cc7e0&gt; (entity: MyClass; id: 0xd000000000300000 &lt;x-coredata://24C40E7B-ECD2-48C5-89A6-03F85727EC5A/MyClass/p12&gt; ; data: {})
  </code></pre>
  
  <p>and </p>
  
  <pre><code>&lt;MyClass: 0x7f9eab672190&gt; (entity: MyClass; id: 0xd000000000040000 &lt;x-coredata://24C40E7B-ECD2-48C5-89A6-03F85727EC5A/MyClass/p1&gt; ; data: {})
  </code></pre>
  
  <p>The two objects have different pointers but should point to the the same Core Data Object. Both have the same <code>&lt;x-coredata://24C40E7B-ECD2-48C5-89A6-03F85727EC5A/DBUser/&gt;</code> but differ in the p12 and p1. What does these lines mean? To the system they are two different object when they should be the same one.</p>
  
  <p>How can I understand what Core Data description string is telling me?</p>
  
  <p>Thanks!</p>
