title: Mapbox iOS SDK 3 - annotation title not showing when annotation is tapped
body: <p>I'm having a hard time figuring out how to make the annotation title appear when a user tapped an annotation pointed to the current location. Everything is working fine except this. I am using <code>CLLocationManager</code> wrapper from <a href="https://github.com/varshylmobile/LocationManager" rel="nofollow noreferrer">https://github.com/varshylmobile/LocationManager</a> but I don't think it's affecting the <code>Mapbox</code> since I can display my pins correctly on the map.</p>
  
  <p>Here's the screenshot sample:</p>

  <p>As you can see, I could run the app without any problems. It's just when I set some annotation title and subtitle to the pin, and tapped it at run-time, it doesn't show anything. </p>
  
  <p>Here's my code snippet for the annotation:</p>
  
  <pre><code>        let point = MGLPointAnnotation()
          point.coordinate = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
          point.title = "Hello world!"
          point.subtitle = "Welcome to The Ellipse."
  
          self.mapView.addAnnotation(point)
  
          let point2 = MGLPointAnnotation()
          point2.coordinate = CLLocationCoordinate2D(latitude: 37.43259552, longitude: location.coordinate.longitude)
          point2.title = "Hello world!"
          point2.subtitle = "Welcome to The Ellipse."
  
          self.mapView.addAnnotation(point2)
  
          self.mapView.selectAnnotation(point, animated: true)
          self.mapView.showAnnotations([point, point2], animated: true)
  </code></pre>
  
  <p>and here is the call out function:</p>
  
  <pre><code>func mapView(mapView: MGLMapView, annotationCanShowCallout annotation: MGLAnnotation) -&gt; Bool {
      return true
  }
  
  func mapView(mapView: MGLMapView, imageForAnnotation annotation: MGLAnnotation) -&gt; MGLAnnotationImage? {
      return nil
  }
  </code></pre>
  
  <p>I am on iOS 9.2, xCode 7.</p>
  
  <p>Thank you!</p>
