Howto access the user's MKAnnotationView on iOS

According to&nbsp;<a href="https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/custom-renderer/map/customized-pin" target="_blank">this</a>&nbsp;tutorial, I added a renderer for a&nbsp;CustomMap&nbsp;to my Xamarin.Forms iOS project. I would like to overwrite the basic&nbsp;Pin&nbsp;with the pin of the user's current location (i.e. the white/blue circle). So I added a class&nbsp;CustomMapRenderer, which overrides the method&nbsp;GetViewForAnnotationas follows

According to this tutorial, I added a renderer for a CustomMap to my Xamarin.Forms iOS project. I would like to overwrite the basic Pin with the pin of the user's current location (i.e. the white/blue circle). So I added a class CustomMapRenderer, which overrides the method GetViewForAnnotationas follows

protected override MKAnnotationView GetViewForAnnotation(MKMapView mapView, IMKAnnotation annotation)
    {
        MKAnnotationView annotationView = null;

    if (annotation is MKUserLocation)
        return null;

    var customPin = getTrackPin(annotation as MKPointAnnotation);
    if (customPin == null)
    {
        throw new Exception("Custom pin not found");
    }

    annotationView = mapView.DequeueReusableAnnotation(customPin.Id.ToString());
    if (annotationView == null)
    {
        annotationView = new TrackMKAnnotationView(annotation, customPin.Id.ToString());
        annotationView.Image = UIImage.FromFile("pin.png");
        annotationView.CalloutOffset = new CGPoint(0, 0);
        annotationView.LeftCalloutAccessoryView = new UIImageView(UIImage.FromFile("monkey.png"));
        annotationView.RightCalloutAccessoryView = UIButton.FromType(UIButtonType.DetailDisclosure);
        ((TrackMKAnnotationView)annotationView).Id = customPin.Id.ToString();
        ((TrackMKAnnotationView)annotationView).Url = customPin.url;
    }
    annotationView.CanShowCallout = true;

    return annotationView;
}

However, instead of doing

annotationView.Image = UIImage.FromFile("pin.png");

I would like to get the UIImage of the pin representing the user's current location, like so (pseudo-code):

annotationView.Image = UIImage.UserPin;

Is there a way to accomplish this?

Refine Objective-C Frameworks for Swift

Refine Objective-C Frameworks for Swift. Objective-C will be gradually replaced with Swift. Before that, there is a lot of opportunity to boost your Objective-C code embracing Swift. This article is the keynote of WWDC Refine Objective-C frameworks for Swift. The nonnull annotation was wrong when Objc returns nil for a value Swift thinks can’t be optional if you are using the NSString or NSArray on Objc side. You will end up with an invalid object and it’s hard to be noticed, because Objc method calls ignore nil, but in some cases, you’ll crash with a null pointer dereference or get other unexpected behavior.
