Hi allI developing an App using swiftui and mapkit that adds several layers to the map : Annotations, Circles and Polyline.I'm adding the polylines the folloiwng way:annotation.coordinate = CLLocationCoordinate2D(latitude: locations.lat, longitude: locations.lon) let contagem = locations_map.count let polyline = MKGeodesicPolyline(coordinates: locations_map, count: contagem ) //print(contagem) let circle = MKCircle(center: destination, radius: locations.accuracy) uiView.setRegion(mapRegion, animated: true) uiView.delegate = context.coordinator uiView.addOverlay(polyline) uiView.addAnnotation(annotation) uiView.addOverlay(circle) Than when I need to remove the annotations the ciecles and the polylines I'm doing the folloiwng uiView.removeAnnotations(uiView.annotations) uiView.removeOverlays(uiView.overlays)But all works except the polylines that persist in the map !!

Hi everyone. This might be a silly question, but I'm new at swift. I have the following piece of code that I call mapView that loads a map with data from a url json . import SwiftUI import MapKit import Combine var locationsFillTest : Int = 0 var allLocations = [MKPointAnnotation]() var doneGettingData : Bool = false {     didSet {         if doneGettingData {             print("The instance property doneGettingData is now true.")         } else {             print("The instance property doneGettingData is now false.")         }     } } struct MapView: UIViewRepresentable {        var startdate : String     var depth: String    func makeUIView(context: Context) -> MKMapView{          MKMapView(frame: .zero)           }       func makeCoordinator() -> MapViewCoordinator{         MapViewCoordinator(self)     }         func updateUIView(_ uiView: MKMapView, context: Context){       uiView.removeAnnotations(allLocations)     allLocations = []     doneGettingData = false          let url = URL(string: "https://xxxx.com")!          URLSession.shared.dataTask(with: url) {(data,response,error) in             do {                 if let d = data {                     let decodedLists = try JSONDecoder().decode(emsc.self, from: d)                     DispatchQueue.main.async {                         locationsFillTest = allLocations.count                         for locations in decodedLists.features {                             var mapRegion = MKCoordinateRegion()                             let mapRegionSpan = 24.0                             mapRegion.span.latitudeDelta = mapRegionSpan                             mapRegion.span.longitudeDelta = mapRegionSpan                             let lat = Double(locations.properties.lat)                             let long = Double(locations.properties.lon                             let annotation = MKPointAnnotation()                             annotation.coordinate = CLLocationCoordinate2D(latitude: lat , longitude: long )                         uiView.addAnnotations(allLocations)                         uiView.delegate = context.coordinator                         uiView.showAnnotations(uiView.annotations, animated: true)                         doneGettingData = true                     }             } catch {                 print("Error decoding JSON: ", error, response!)             }         }.resume()          }      } struct MapView_Previews: PreviewProvider {     static var previews: some View {         MapView(startdate: "2020-08-23",depth: "All")     } } so far so good the points get to the map, and the variable doneGettingData does change from false too true when all the points are loaded. But now I would like to use this variable to set a spinner in my contentView, the issue is that although the variable its available and I can see it changing in the print statement it does not change in the contentView, I have tested with a Text so I could checked it. Any ideias please ? Thank you

Hi guys I have the following problem: I have MapKit view in swiftui where I'm updating a boolean variable so I know when all the data points are displayed. I have created the following class and I can "see" the variable changing from false to true and vice versa. class GettingData: ObservableObject {              @Published var doneGettingData : Bool = false              {         didSet {             if doneGettingData {                 print("The instance property doneGettingData is now true.")             } else {                 print("The instance property doneGettingData is now false.")             }         }     } } The problem is how to use this variable in ContentView so I can turn on and off a spinner. I have tried several approaches but nothing works. In MapView I'm doing it the following way struct MapView: UIViewRepresentable {          let shared = GettingData()     var startdate : String     var depth: String        // The makeUIView(context:) method is creates an empty Map View.            func makeUIView(context: Context) -> MKMapView{          MKMapView(frame: .zero)           }         func makeCoordinator() -> MapViewCoordinator{         MapViewCoordinator(self)     }         func updateUIView(_ uiView: MKMapView, context: Context){       self.shared.doneGettingData = false \\\\ rest of the code uiView.addAnnotations(allLocations) self.shared.doneGettingData = true \\\\ rest of the code                          The variable does change when I have everything in the map But how to use it for the spinner ? Any ideias please ? Thank you
