Ok, I found a solution if anyone else will ever need it. I added a UITapGestureRecognizer to my map view instance. I used the MKMapView's convert(_:toCoordinateFrom:) to convert the touch point to the map coordinates I created a MKMapPoint from that coordinate and checked if the MKPolygon renderer path contains the point For the MKPolygon, being a MKShape after all, I used the .title property to assign my zone_id value parsed from the GeoJSON. So I was able to identify which polygon was tapped. I attached the code MapView.swift MapViewModel.swift

Well, as it is being my first app, I did not know that i have to set also the price. I thought if I don't set any price, will be available for free. Anyway, now it's live.
