title: User ID not displaying in Google Analytics dashboard (iOS)
body: <p>I'm trying to link GA's User ID feature to my iOS app, but this doesn't seem to be working. From the documentation, I enables a User ID capable view (profile). Then, I set the userId field.</p>
  
  <p>My code:
  AppDelegate.m</p>
  
  <pre><code>id&lt;GAITracker&gt; tracker = [[GAI sharedInstance] defaultTracker];
  
  // You only need to set User ID on a tracker once. By setting it on the tracker, the ID will be
  // sent with all subsequent hits.
  [tracker set:@"&amp;uid"
         value:@"userIDTest"];
  
  
  // This hit will be sent with the User ID value and be visible in User-ID-enabled views (profiles).
  [tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"User Test"            // Event category (required)
                                                        action:@"User Sign In"  // Event action (required)
                                                         label:nil              // Event label
                                                         value:nil] build]];    // Event value
  </code></pre>
  
  <p>However, in the analytics dashboard:</p>

  <p>I can't seem to find one place where I can see the user id.</p>
