  </code></pre>
  
  <p>I try to save it like this:</p>
  
  <pre><code>try! realm.write{
                  self.realm.add(self.theEvent)
              }
  </code></pre>
  
  <p>My Event object looks something along these lines:</p>
  
  <pre><code>class Event: Object {
  dynamic var title: String = ""
  dynamic var image: NSData = NSData()
  let items = List&lt;Item&gt;()
  }
  </code></pre>
  
  <p>Where an Item is basically just another object that stores one photo.</p>
  
  <p>I am confused as to why attempting to save just 2 photos (1 item in the list plus the image for the event) results in realm claiming it is over 16MB.  </p>
  
  <p>Thank you!</p>
