 Keep these things in the back of your mind when using observers:
 
 * Observers may be notified in the background queue of the client. You can use
-  `dispatch_async` to jump to a different queue.
+  `DispatchQueue` to jump to a different queue.
 * Observers must be explicitly removed to prevent memory leaks. The destructor
   is a good place to remove an observer in the object lifecycle. You can
   add as many observers as you want as long as you remove them when you're done.
