如何使用google direction API在苹果地图上快速绘制路线？

import MapKit

func drawRouteOnAppleMap(startLocation: CLLocationCoordinate2D, endLocation: CLLocationCoordinate2D) {
    let directionsRequest = MKDirections.Request()
    let startPlacemark = MKPlacemark(coordinate: startLocation)
    let endPlacemark = MKPlacemark(coordinate: endLocation)
    
    directionsRequest.source = MKMapItem(placemark: startPlacemark)
    directionsRequest.destination = MKMapItem(placemark: endPlacemark)
    directionsRequest.transportType = .automobile
    
    let directions = MKDirections(request: directionsRequest)
    directions.calculate { (response, error) in
        guard let route = response?.routes.first else {
            // 处理错误情况
            return
        }
        
        // 获取路线的坐标点
        let routeCoordinates = route.polyline.coordinates
        
        // 在地图上绘制路线
        let polyline = MKPolyline(coordinates: routeCoordinates, count: routeCoordinates.count)
        mapView.addOverlay(polyline)
    }
}
