title: How to fetch records from a class which has parent class reference?
body: <p>I'm new to CoreData structure, I have two classes one is "<code>Person.h</code>" and another is "<code>Education.h</code>" which has one to many relations ship <code>Person</code>&lt;--->> Education`.</p>
  
  <p>Here's the attributes for each classes,</p>
  
  <p><strong>Person.h</strong></p>
  
  <pre><code>personID (unique) Number
  pName String
  pAge Number
  educations Set
  </code></pre>
  
  <p>here, p stands for person </p>
  
  <p><strong>Education.h</strong></p>
  
  <pre><code>educationID (unique) Number
  eName String
  eState Number
  eStarted String
  eCompleted String
  eCenterName String
  eBy Person
  </code></pre>
  
  <p>here, e stands for education </p>
  
  <p>Ok, now I want to fetch (all / some) education details for a Person. I've successfully inserted records in both the classes with proper inputs. How to get this done? Any suggestion? Please consider me to correcting, even if this flow would not clear to you (or its wrong).</p>
  
  <p>Thanks, </p>
