Highlight between two points on MapKit swift 5 - ios

Question

I am struggling to try and Highlight the road between 2 points using MapKit. All I don't want directions i just want to try and Highlight the road between these two points.
My code is:
import UIKit
import MapKit
class ViewController: UIViewController {
#IBOutlet weak var mapView: MKMapView!
struct Points {
var name: String
var lattitude: CLLocationDegrees
var longtitude: CLLocationDegrees
}
override func viewDidLoad() {
super.viewDidLoad()
let points = [
Points(name: "Point 1", lattitude: 52.100525, longtitude: -9.623071),
Points(name: "Point 2", lattitude: 52.07241, longtitude: -9.575299)
]
fetchPointsOnMap(points)
}
func fetchPointsOnMap(_ points: [Points]) {
for points in points {
let annotations = MKPointAnnotation()
annotations.title = points.name
annotations.coordinate = CLLocationCoordinate2D(latitude:
points.lattitude, longitude: points.longtitude)
mapView.addAnnotation(annotations)
}
}
}`

You can draw a line:
directionsRequest.transportType = MKDirectionsTransportType.automobile
//Draw polyline by using MKRoute so it follows the street roads...
for (k, item) in arrayarrayPlacemarks.enumerated() {
if k < (arrayarrayPlacemarks.count - 1) {
directionsRequest.source = item
directionsRequest.destination = arrayarrayPlacemarks[k+1]
let directions = MKDirections(request: directionsRequest)
directions.calculate { (response:MKDirections.Response!, error: Error!) -> Void in
if error == nil {
self.locRoute = response.routes[0] as? MKRoute
let geodesic:MKPolyline = self.locRoute!.polyline
self.mapView.addOverlay(geodesic)
}
}
}
}
Delegate:
func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {
if overlay.isKind(of: MKPolyline.self){
var polylineRenderer = MKPolylineRenderer(overlay: overlay)
polylineRenderer.fillColor = UIColor.blue
polylineRenderer.strokeColor = UIColor.blue
polylineRenderer.lineWidth = 2
return polylineRenderer
}
return MKOverlayRenderer(overlay: overlay)
}
