MKDirections : Directions Not Available

Question

I am creating an app like an UBER and i am using MapKit ,i want to display route between two locations and for this i have use following code

    viewMap.delegate = self

    let sourceLocation = CLLocationCoordinate2D(latitude: sourceLatitude, longitude: sourceLongitude)
    let destinationLocation = CLLocationCoordinate2D(latitude: destinationLatitude, longitude: destinationLongitude)

    let sourcePlacemark = MKPlacemark(coordinate: sourceLocation, addressDictionary: nil)
    let destinationPlacemark = MKPlacemark(coordinate: destinationLocation, addressDictionary: nil)

    let sourceMapItem = MKMapItem(placemark: sourcePlacemark)
    let destinationMapItem = MKMapItem(placemark: destinationPlacemark)

    let sourceAnnotation = MKPointAnnotation()
    sourceAnnotation.title = strSource

    if let location = sourcePlacemark.location {
        sourceAnnotation.coordinate = location.coordinate
    }


    let destinationAnnotation = MKPointAnnotation()
    destinationAnnotation.title = strDestination

    if let location = destinationPlacemark.location {
        destinationAnnotation.coordinate = location.coordinate
    }

    self.viewMap.showAnnotations([sourceAnnotation,destinationAnnotation], animated: true )

    let directionRequest = MKDirectionsRequest()

    directionRequest.source = sourceMapItem
    directionRequest.destination = destinationMapItem
    directionRequest.transportType = .automobile

    let directions = MKDirections(request: directionRequest)

    directions.calculate {
        (response, error) -> Void in

        guard let response = response else {
            if let error = error {
                print("Route Error: \(error)")
            }

            return
        }

        let route = response.routes[0]
        self.viewMap.add((route.polyline), level: MKOverlayLevel.aboveRoads)

        let rect = route.polyline.boundingMapRect
        self.viewMap.setRegion(MKCoordinateRegionForMapRect(rect), animated: true)
    }

extension HomeVC: MKMapViewDelegate

func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {
    let renderer = MKPolylineRenderer(overlay: overlay)
    renderer.strokeColor = #colorLiteral(red: 0.2392156869, green: 0.6745098233, blue: 0.9686274529, alpha: 1)
    renderer.lineWidth = 2.0

    return renderer
}

I have check all the possible solution and i am also getting latitude and longitude of source and destination Locations but i still its not working and i am getting following error.

Please help me with this!

Apple maps directions is available to specific countries only. Please check full list here. Apple Map Availability list (Check in Maps: Directions section). You should look into Google Map SDK in your app is targeting countries not listed in above link.

This works for me and it draws the destination in the MK Map, also it focuses to the destination

func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
        let request = MKDirectionsRequest()
        request.source = MKMapItem.forCurrentLocation()
        request.destination = MKMapItem(placemark: MKPlacemark(coordinate: (view.annotation?.coordinate)!))
        request.requestsAlternateRoutes = true
        request.requestsAlternateRoutes = true
        request.transportType = .walking
        let directions = MKDirections(request: request)
        directions.calculate { [unowned self] response, error in
            guard let unwrappedResponse = response else { return }

            for route in unwrappedResponse.routes {
                self.myMapView.add(route.polyline)                self.myMapView.setVisibleMapRect(route.polyline.boundingMapRect, animated: true)
                return
            }
        }

    }


func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {
        let polyLine = overlay
        let polyLineRenderer = MKPolylineRenderer(overlay: polyLine)
        polyLineRenderer.strokeColor = UIColor.blue
        polyLineRenderer.lineWidth = 2.0
        return polyLineRenderer
    }

this works when you click on a MKAnnotationView, if you want to draw from another code you just have to cut the code to your function and change the line

request.destination = MKMapItem(placemark: MKPlacemark(coordinate: (view.annotation?.coordinate)!))

to

request.destination = MKMapItem(placemark: MKPlacemark(coordinate: (CLLocationCoordinate2D(/*Your Location*/))!))
