title: Possible to dynamically fetch all entity relationships?
body: <p>Using Xcode 9 swift 4, is it possible to dynamically fetch all relationships for an entity? I can’t seem to find any examples that can get all relationship data from an entity without hard-coding relationship names.</p>
  
  <p><strong>Edit</strong>: I miss-explained my original question, fixed above. Adding my static code, which grabs an relationship data by name rather than dynamically.</p>
  
  <p><em>Disease</em> is an entity with a many-many relationship <em>own_pathology_organs</em> to another entity <em>Pathology_Organs</em>. </p>
  
  <pre><code>let pathology_organs = disease.own_pathology_organs?.allObjects as! [Pathology_Organs]
  for pathology_organ in pathology_organs{
      pathologyArray.append(pathology_organ.name!)
  }
  </code></pre>
