ios – Swift detailCalloutAccessoryView change type not working

I am utilizing MKAnnotationView to point out a customized view when a person faucets a pin on the map. The customized view shows superb and I am utilizing func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) to point out it.

I am utilizing the detailCalloutAccessoryView as I have to have the tableView contained in the detailCalloutAccessoryView. The issue I am having is that I can not change the backgroundColor, take away the padding or take away the Shadow opacity of the detailAccessoryView.

I’ve additionally tried to unravel this by making a customView and alter the CanShowCallout to false and simply add it to the view utilizing view.addSubView(customView) which appears precisely because the design nonetheless the tableView does not scroll – I suppose that is as a result of it is only a view.

How can I modify the detailAccessoryView?

view.detailCalloutAccessoryView?.superview?.layer.cornerRadius = 10
        view.detailCalloutAccessoryView?.superview?.backgroundColor = UIColor(named: "Purple") ?? purple
        view.detailCalloutAccessoryView?.superview?.layer.shadowOpacity = 0
