title: Realm LinkingObjects property is not appearing in Realm Explorer
body: <p>I'm fairly new to iOS Development and Realm, with decent experience in code first database building.</p>
  
  <p>I have a one to many relationship between classes <strong>Routine</strong> and <strong>Workout</strong>, where one Routine may contain many different workouts. Here are my classes: </p>
  
  <pre><code>class Routine: Object {
      //Properties
      dynamic var id : Int = 0
      dynamic var routineName : String = ""
  
      //Relationships
      let workouts = LinkingObjects(fromType: Workout.self, property: "routine")
  
      //Primary Key Declaration
      override static func primaryKey() -&gt; String? {
          return "id"
      }
  } 
  </code></pre>
  
  <hr>
  
  <pre><code>class Workout: Object {
      //Properties
      dynamic var id : Int = 0
      dynamic var workoutName : String = ""
  
      //Relationships
      let exercises = List&lt;Exercise&gt;()
      dynamic var routine : Routine?
  
      //Primary Key Declaration
      override static func primaryKey() -&gt; String? {
          return "id"
      }
  }
  </code></pre>
  
  <p>Am I doing this right for the desired relationship? When I build this and look in the Realm Browser the property <code>workouts</code> in Routine does not appear.</p>
  
  <p>Thanks.</p>
