SWIFT MapView MKRoutePolyline interiorPolygons: selettore non riconosciuta inviati esempio 0x14ed4b4d0

Question

che sto cercando di fare un app di navigazione

Ma questo incidente app quando ho cercando di navigare e mostrare "MKRoutePolyline

interiorPolygons: selettore non riconosciuta inviati a istanza 0x14ed4b4d0 "

cosa c'è di sbagliato nel mio codice?

import UIKit 
import MapKit 
class MapViewController: UIViewController, MKMapViewDelegate { 
var farm:Farm! 

var currentPlacemark:CLPlacemark? 

let locationManager = CLLocationManager() 
var currentTransportType = MKDirectionsTransportType.Automobile 
var currentRoute:MKRoute? 




@IBOutlet var mapView:MKMapView! 
@IBAction func showDirection(sender: AnyObject){ 
    let directionRequest = MKDirectionsRequest() 

    directionRequest.source = MKMapItem.mapItemForCurrentLocation() 
    let destinationPlacemark = MKPlacemark(placemark: currentPlacemark!) 
    directionRequest.destination = MKMapItem(placemark: destinationPlacemark) 
    directionRequest.transportType = currentTransportType 

    let directions = MKDirections(request: directionRequest) 

    directions.calculateDirectionsWithCompletionHandler { (routeResponse, routeError) -> Void in 

     guard let routeResponse = routeResponse else { 
      if let routeError = routeError { 
       print("Error: \(routeError)") 
      } 

      return 
     } 

     let route = routeResponse.routes[0] 
     self.currentRoute = route 
     self.mapView.removeOverlays(self.mapView.overlays) 
     self.mapView.addOverlay(route.polyline, level: MKOverlayLevel.AboveRoads) 



    } 
} 


func mapView(mapView: MKMapView, rendererForOverlay overlay: MKOverlay) -> MKOverlayRenderer { 
    let renderer = MKPolygonRenderer(overlay: overlay) 
    renderer.strokeColor = UIColor.yellowColor() 
    renderer.lineWidth = 3.0 

    return renderer 

}

Sembra che si desidera eseguire il rendering di una linea.
ma poligono è una forma
modo che il codice dovrebbe essere:

let renderer = MKPolylineRenderer(overlay: overlay) 

Ma non:

let renderer = MKPolygonRenderer(overlay: overlay) 

in

func mapView(mapView: MKMapView, rendererForOverlay overlay: MKOverlay) -> MKOverlayRenderer
