Reply to How To Create Heatmap From Array CLCoordinate2D In A SwiftUI Map
@robnotyou quick question. Since MKMapView doesnt require a binding to region, my map shows empty blue (probably in the middle of the sea).  @State private var region = MKCoordinateRegion() MapView(region: region) .edgesIgnoringSafeArea(.all) .onAppear() {     region = ... array of CLLocationCoordinate2D }  This used to work when it was Map since i just had to go $region since the parameter required has to be binding but now it is not. How can it re-render once the region variable is set?  This is my MapView import SwiftUI import MapKit struct MapView: UIViewRepresentable {   var region: MKCoordinateRegion   var polylineCoordinates: [CLLocationCoordinate2D]?   func makeUIView(context: Context) -> MKMapView {     let mapView = MKMapView()     mapView.delegate = context.coordinator     mapView.region = region          if let polylines = polylineCoordinates {       let polyline = MKPolyline(coordinates: polylines, count: polylines.count)       mapView.addOverlay(polyline)     }           return mapView   }   func updateUIView(_ view: MKMapView, context: Context) {        }   func makeCoordinator() -> Coordinator {     Coordinator(self)   } } class Coordinator: NSObject, MKMapViewDelegate {   var parent: MapView   init(_ parent: MapView) {    self.parent = parent   }       func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {     if let routePolyline = overlay as? MKPolyline {       let renderer = MKPolylineRenderer(polyline: routePolyline)       renderer.strokeColor = UIColor.systemBlue       renderer.lineWidth = 5       return renderer     }     return MKOverlayRenderer()   } }
