title: Xamarin Forms iOS Local Notifications not displaying
body: <p>I'm building an application in Xamarin.Forms, and am having trouble getting the Local Notifications to display in iOS.
  I've followed the guide from <a href="https://developer.xamarin.com/guides/ios/platform_features/user-notifications/enhanced-user-notifications/" rel="nofollow noreferrer">https://developer.xamarin.com/guides/ios/platform_features/user-notifications/enhanced-user-notifications/</a> and the notification still doesnt display.
  I've added the following to my FinishedLaunching method in AppDelegate:</p>
  
  <pre><code>    UNUserNotificationCenter.Current.RequestAuthorization (UNAuthorizationOptions.Alert, (approved, err) =&gt; {});
  </code></pre>
  
  <p>And in my page where I'd like the notification to display:</p>
  
  <pre><code>using UserNotifications;
  
  
  var content = new UNMutableNotificationContent ();
  content.Title = "Notification Title";
  content.Subtitle = "Notification Subtitle";
  content.Body = "Test Notification.";
  content.Badge = 1;
  
  var trigger =  UNTimeIntervalNotificationTrigger.CreateTrigger (5, false);
  
  var requestID = "sampleRequest";
  var request = UNNotificationRequest.FromIdentifier (requestID, content, 
  trigger);
  
  UNUserNotificationCenter.Current.AddNotificationRequest (request, (err) =&gt; {
  if (err != null) {
      // Do something with error...
  }
  });
  </code></pre>
  
  <p>All of my nuGet packages are up to date, and I've tried testing on both iOS iPhone simulators, and a physical iPad device.</p>
  
  <p>Is there something I am missing here?</p>
