title: Mapbox Map for first time users with no connectivity
body: <p>I need help with displaying a default mapView to first-time users with no network connectivity. Then as soon as the network is available, load the mapView using the styleURL.</p>
  
  <p>The latter part is taken care of, however, I'm still struggling with displaying the mapView for the first-time users using the local styles I downloaded from Mapbox:</p>
  
  <pre><code>let localURL = Bundle.main.url(forResource: "style", withExtension: "json")
  
  if Reachability.isConnectedToNetwork() == true {
      mapView = MGLMapView(frame: view.bounds, styleURL: styleURL)
      ...
  } else {
      mapView = MGLMapView(frame: view.bounds, styleURL: localURL)
      ...
  }
  </code></pre>
  
  <p>Am I missing something?</p>
