title: Use multiple managed objects context with core data base
body: <p>I am using core data to store and fetch my data but I am facing some issue. I want to use two thread parallel for following operations:</p>
  
  <ol>
  <li>Thread one will insert data in CoreData base table(A).</li>
  <li>Thread two will fetch data from another table(B).</li>
  </ol>
  
  <p><strong>How I can do that?</strong></p>
  
  <p>I did some research on google and they said, we need to use multiple managed object context, But I don't know how we will use that.</p>
