Estoy tratando de crear una aplicación que muestre algunas áreas (polígonos/superposiciones) en el mapa y cuando se toca un polígono, me gustaría imprimir en la impresión de la consola ("Se ha tocado el polígono \(zone_id)"). Los polígonos se representan desde un archivo GeoJSON donde también podemos encontrar zone_id en la función de propiedades. Hasta ahora, he renderizado las superposiciones en el mapa, pero estoy atascado y agradezco alguna orientación sobre dónde ir desde aquí.

Pegaré mi código que tengo hasta ahora y también un fragmento del archivo GeoJSON.

 import SwiftUI import CoreLocation struct Home: View {    @StateObject var mapData = MapViewModel()    var body: some View {    ZStack{            MapView()        .environmentObject(mapData)        .ignoresSafeArea(.all, edges: .all)            }  } } struct Home_Previews: PreviewProvider {  static var previews: some View {    Home()  } }

 import SwiftUI import MapKit struct MapView: UIViewRepresentable {    @EnvironmentObject var mapData: MapViewModel    @State var restrictions: [MKOverlay] = []    func makeCoordinator() -> Coordinator {    return MapView.Coordinator()  }    func makeUIView(context: Context) -> MKMapView {        let view = mapData.mapView        view.showsUserLocation = true    view.delegate = context.coordinator        mapData.showRestrictedZones { (restrictions) in      self.restrictions = restrictions      view.addOverlays(self.restrictions)    }    return view  }    func updateUIView(_ uiView: MKMapView, context: Context) {      }    class Coordinator: NSObject, MKMapViewDelegate {        func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {      if let polygon = overlay as? MKPolygon {        let renderer = MKPolygonRenderer(polygon: polygon)        renderer.fillColor = UIColor.purple.withAlphaComponent(0.2)        renderer.strokeColor = .purple.withAlphaComponent(0.7)                return renderer      }      return MKOverlayRenderer(overlay: overlay)    }  } }

 import SwiftUI import MapKit // All Map Data Goes here... class MapViewModel: NSObject, ObservableObject {    @Published var mapView = MKMapView()       // Decode GeoJSON from the server  func showRestrictedZones(completion: @escaping ([MKOverlay]) -> ()) {    guard let url = URL(string: "https://flightplan.romatsa.ro/init/static/zone_restrictionate_uav.json") else {      fatalError("Unable to get geoJSON") }        downloadData(fromURL: url) { (returnedData) in      if let data = returnedData {        var geoJson = [MKGeoJSONObject]()        do {          geoJson = try MKGeoJSONDecoder().decode(data)        } catch {          fatalError("Unable to decode GeoJSON")        }        var overlays = [MKOverlay]()        for item in geoJson {          if let feature = item as? MKGeoJSONFeature {            for geo in feature.geometry {              if let polygon = geo as? MKPolygon {                overlays.append(polygon)                              }            }          }        }        DispatchQueue.main.async {          completion(overlays)        }      }    }  }    func downloadData( fromURL url: URL, completion: @escaping (_ data: Data?) -> ()) {    URLSession.shared.dataTask(with: url) { (data, response, error) in      guard        let data = data,        error == nil,        let response = response as? HTTPURLResponse,        response.statusCode >= 200 && response.statusCode < 300 else {        print("Error downloading data.")        completion(nil)        return      }      completion(data)    }    .resume()  } }

Y aquí hay un fragmento de la estructura GeoJSON
