title: Problems with NSSet (remove object and iterate)
body: <p>I am currently working on a project that uses CoreData and relations are using NSSet. I have currently 2 problems :</p>
  
  <ol>
  <li><p>How to iterate over an NSSet using an index ? --> SOLVED</p></li>
  <li><p>How to remove a specific object ? => I guess I need to iterate and check for the object ?</p></li>
  </ol>
  
  <p>hmm looks like I also have a problem adding an object ? Whats wrong with this :</p>
  
  <pre><code>    [mySet setByAddingObject:info];
  </code></pre>
  
  <p>Thanks for the help.</p>
