The default MapMarker hides information that is under it, for example a city name. If zoomed closed enough the marker doesn't cover the name anymore and the name is displayed. When using a custom annotation view both the city name and the annotation is displayed, it looks a lil messy. Is it possible to get the behaviour from MapMarker when using custom annotations?

Maybe something with clustering or collisions, but seems do be annotations colliding with annotations.
setting the value of .displayPriority
to some value seems to do the trick. Don't know which value to set though.
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
let annotation = MKAnnotationView(annotation: annotation, reuseIdentifier: "annotation")
annotation.image = UIImage(systemName: "circle.fill")
annotation.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
annotation.displayPriority = .defaultHigh
return annotation
}
