title: Sygic issue in calculating the route
body: <p>I have a problem when I tried to add a route in my <strong>Sygic offline map view</strong>. In the debugger, I got this message " Routing interface: Asking for unknown transport mode." this the code that I wrote:</p>
  
  <pre><code>   class SygicMapViewController: UIViewController, SYNavigationDelegate,SYRoutingDelegate,SYMapViewDelegate,CLLocationManagerDelegate{
      let mapView = SYMapView()
      let routing = SYRouting()
      var  locationManager = CLLocationManager()
      override func viewDidLoad() {
          super.viewDidLoad()
          mapView.delegate = self
          locationManager.delegate = self
          locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation
          locationManager.requestAlwaysAuthorization()
          locationManager.requestWhenInUseAuthorization()
          locationManager.startUpdatingLocation()
      }
      func setupMapView(){
          let tiltFor2D: SYAngle = 0
          mapView.tilt = tiltFor2D
          mapView.zoom = 12
          mapView.rotation = 180
          mapView.frame = CGRect(x: 0, y: 0, width: self.view.frame.size.width, height:self.view.frame.size.height+20)
          self.view.addSubview(mapView)
          mapView.renderEnabled = true
      }
      func addMarkers(){
  
      }
      func mapView(_ mapView: SYMapView, didFinishInitialization success: Bool) {
          setupMapView()
          SYNavigation.shared().delegate = self
          routing.delegate = self
          let startPoint = SYGeoCoordinate(latitude: 37.270665, longitude:  9.873921)
          let endPoint = SYGeoCoordinate(latitude: 37.242681, longitude: 9.911932)
          computeRoute(from: startPoint!, to: endPoint!)
      }
      func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
          print(error)
      }
      override func didReceiveMemoryWarning() {
          super.didReceiveMemoryWarning()
          // Dispose of any resources that can be recreated.
      }
      func computeRoute(from fromCoordinate: SYGeoCoordinate, to toCoordinate:
          SYGeoCoordinate) {
          let startWaypoint = SYWaypoint(position: fromCoordinate, type: .start, name: "Begin")
          let endWaypoint = SYWaypoint(position: toCoordinate, type: .end, name: "End")
          let routingOptions = SYRoutingOptions()
          routingOptions.transportMode = .unknown// For other options see SYTransportMode
          routingOptions.routingType = .economic// For other options see SYRoutingType
          routing.computeRoute(startWaypoint, to: endWaypoint, via: nil, with: routingOptions)
      }
  
      func routing(_ routing: SYRouting, computingFailedWithError error: SYRoutingError) {
          print(error)
      }
  
      func routing(_ routing: SYRouting, didComputePrimaryRoute route: SYRoute?) {
          SYNavigation.shared().start(with: route)
          // You might want to put it also on the map
          let mapRoute = SYMapRoute(route: route!, type: .primary)
          mapView.add(mapRoute)
          mapView.cameraMovementMode = .followGpsPosition
      }
  }
  </code></pre>
  
  <p>I correct the issue by selecting the local routing variable in the computeRoute method and I made some changes to fire the computeRoute method after the mapview Intialization </p>
