title: Mapbox not loading streets and details: Failed to load mapbox://mapbox.mapbox-streets-v6
body: <p>Just installed <code>MapboxGL</code> through cocoapods. 
  I initialize it in my <code>ViewController</code> like the example given:</p>
  
  <pre><code> @IBOutlet weak var mapViewWrapper: UIView!
  
      var mapView: MGLMapView!
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
          // Map
          let styleURL = NSURL(string: "asset://styles/dark-v7.json")
          mapView = MGLMapView(frame: mapViewWrapper.bounds, styleURL: styleURL)
          mapView.autoresizingMask = .FlexibleWidth | .FlexibleHeight
  
          // set the map's center coordinate
          mapView.setCenterCoordinate(CLLocationCoordinate2D(latitude: 38.894368,
              longitude: -77.036487),
              zoomLevel: 15, animated: false)
          mapViewWrapper.addSubview(mapView)
  
      }
  </code></pre>
  
  <p>When I launch the app, I see a black square and a Mapbox logo but no streets, see image below

  <p>In the logs I'm getting this: </p>
  
  <pre><code>[ERROR] {Map}[Style]: Failed to load [mapbox://mapbox.mapbox-streets-v6]: 
  [ERROR] {Map}[Style]: Failed to load [mapbox://mapbox.mapbox-terrain-v2]: 
  </code></pre>
  
  <p>Any ideas what I did wrong?  </p>
