使用Apple新的注释图钉徽标更改注释图钉的颜色

Question

I'm trying to change the colour of my annotation pins. However, I am wanting it to change the colour of the new Apple annotation logo. Instead, when the colours change, the new logo (as shown below) converts to the old logo (as shown below).

Is there anyway to change the colour as well as keep the new annotation pin?

Here's my code:

class MyPointAnnotation : MKPointAnnotation {
    var pinTintColor: UIColor?
}

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
    var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: "myAnnotation") as? MKPinAnnotationView

    if annotationView == nil {
        annotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "myAnnotation")
        annotationView?.canShowCallout = true
       } else {
        annotationView?.annotation = annotation
    }
    if annotation is MKUserLocation {
        return nil
    }
    if let annotation = annotation as? MyPointAnnotation {
        annotationView?.pinTintColor = annotation.pinTintColor
    }
            return annotationView
}

self.map.delegate = self
/// in view did load

Old pin:

New pin:

any input would be greatly appreciated!

Use MKMarkerAnnotationView instead of MKPinAnnotationView.

if annotationView == nil {
    annotationView = MKMarkerAnnotationView(annotation: annotation, reuseIdentifier: "myAnnotation")
    annotationView?.canShowCallout = true
   } else {
    annotationView?.annotation = annotation
}

MKMarkerAnnotationView uses markerTintColor rather than pinTintColor. However, this only works on iOS 11. The new icon is only present in iOS 11.
