title: Does the @FetchRequest property wrapper automatically notify when changes happen?
body: <p>If I'm using an NSPersistentCloudKitContainer, I see in the sqlite file that changes are automatically synced. I can also make changes in the CloudKit Dashboard, restart the app and see the changes. If I use <code>@FetchRequest</code> to load some items, should the items array automatically update?</p>
  <pre class="lang-swift prettyprint-override"><code>// Fetch some items
  @FetchRequest(
          sortDescriptors: [NSSortDescriptor(keyPath: \Item.timestamp, ascending: true)],
          animation: .default)
      private var items: FetchedResults&lt;Item&gt;
  
  // Show them in a List
  
  List(items) { item in
    VStack {
      Text(&quot;Item at \(item.timestamp!, formatter: itemFormatter)&quot;)
    }
  }
  </code></pre>
