Hello everyone, I have a SwiftUI application with a view containing a MapKit map as UIViewRepresentable. I'm experience the following issue with regionDidChangeAnimated that seems related to MapKit itself as I was able to reproduce it also on another application I'm developing. The problem is that regionDidChangeAnimated is not getting called when zooming in or out, but it's getting called for other gestures, like panning and moving the map. This is what I noticed: I zoom in/out on the map regionWillChangeAnimated is called I release my fingers from the map regionDidChangeAnimated is NOT called If I move a bit the map -> regionDidChangeAnimated is called ( for the previous touch ), then regionWillChangeAnimated related to the new touch is called, regionDidChangeAnimated for the new touch is called. So it looks like when zooming in/out, regionDidChangeAnimated is lagging and not called until a new touch happens. Did you ever experienced this behavior? Thank you in advance for your support

I am trying to load an auxiliary window from an AppKit bundle that loads a NSViewController from a storyboard. This NSViewController displays a MKMapView. I want to avoid supporting multiple windows from my Catalyst app so I do not want to load this window via a SceneDelegate, and that is why I have chosen to go the AppKit bundle route. If I load a similar view controller which contains a single label, then all works as expected. However, if I try to load a view controller with the MKMapView, I get the following error after crashing: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MKMapView nsli_piercingToken]: unrecognized selector sent to instance 0x15410f600' DropBox link to sample app with buttons on a view to select either the "Map View" (crashing) or the "Label View" (working): https://www.dropbox.com/scl/fi/q9daurhzqvil9o2ry6k1t/CatalystMap.zip?rlkey=yjbqfn6uxfrfh1jgsdavagta7&dl=0

Good afternoon, I'd like to get detailed information about the price usage of the Apple Map in my app in IOS (Swiftui for Iphone and Ipad). I'd like to establish a future price for the app subscription and to do that I need to obtain the precise prices for opening the map, consulting Map items, creating routes, the price of each consulting, and any other price that is related to the map usage process. I have been searching for this information and it has not been easy to find answers. I appreciate it if I could get the information. Best regards, Marcello Lima

Hi there, I am trying to develop a country guessing game using MapKit and GeoJSON data. I have verified that my data creates the outline of the country properly using other methods, but I run into an error where the map clips and does not show portions of the countries or islands when zooming at certain levels of the map. I receive the warnings in the terminal "Mismatching number of indices, indexCount: 30, triangulatedIndexCount: 27" and "Triangulator failed to fully triangulate polygon: (0.1296, 0.303328), (0.108053, 0.296605), (0.0671644, 0.289883), (0.0586311, 0.281121), (0.0397156, 0.27289), (0.0323911, 0.262393), (0.0610489, 0.260732), (0.102507, 0.284671), (0.140053, 0.292602), (0.133511, 0.291167), (0.137707, 0.293659), (0.138489, 0.29872)" I am not sure what these tuple values are, or how to fix the errors, as I have adjusted my data (removing duplicate coordinates, refreshing the map, etc). How am I able to counteract these warnings, or at least get a sense of what they are asking?

Is it possible to programmatically force iphone to use cellular internet during WIFI connection? I am connected via WIFI to a device with no internet connection. But I need to use MapKit

Hello, I have a question. I have a LookAroundPreview, that loads correctly a scene, and when I tap on it, it natively shows a view I can navigate in, and that I can close. All that is ok. However, when I want to display that same LookAroundPreview in a fullScreenCover (because my app needs it for navigation purposes), it directly shows the navigatable View with the closeButton. That I don't want. Is there an option to pass, that I missed? Is this a bug of the LookAroundPreview? Or is this wanted by Apple devs? Thank you very much for your help, Sincerely import SwiftUI struct ContentView: View { @State private var displayFullScreen = false //AppleLookAroundView is just a wrapper around native LookAroundPreview, that loads a NYC coordinate var body: some View { VStack { AppleLookAroundView() Spacer() Button("Display fullScreen cover") { displayFullScreen = true } Spacer() } .fullScreenCover(isPresented: $displayFullScreen) { VStack { AppleLookAroundView() Text("⬆ It somehow detects it is in a fullScreenCover and unwantingly change its display") } } } } import SwiftUI import MapKit import CoreLocation struct AppleLookAroundView: View { @State private var scene: MKLookAroundScene? let coordinate = CLLocationCoordinate2D(latitude: 40.651238394229324, longitude: -73.96432239237737) var body: some View { LookAroundPreview(scene: $scene, allowsNavigation: true, badgePosition: .bottomTrailing) .task { do { scene = try await fetchScene(for: coordinate) } catch { print("Couldn't fetch scene") } } .frame(height: 300) } private func fetchScene(for coordinate: CLLocationCoordinate2D) async throws -> MKLookAroundScene? { let lookAroundScene = MKLookAroundSceneRequest(coordinate: coordinate) let scene = try await lookAroundScene.scene return scene } } ![]("https://developer.apple.com/forums/content/attachment/a10a7701-dd8c-4d83-9a03-848cf0373417" "title=Capture d’écran 2024-04-24 à 12.56.46.png;width=898;height=1860") `` ![]("https://developer.apple.com/forums/content/attachment/d54f7fe1-aac8-4280-ab97-663f0bdd440f" "title=Capture d’écran 2024-04-24 à 12.56.34.png;width=924;height=1882") `

On iPhone 14 Pro running iOS 17.4.1, tapping on MKMapView triggers a dozen or more additional hitTest calls. At the moment, only one device has encountered this issue.Not sure if it's a hardware issue or a bug with MKMapView. Adding MKMapView to the app could potentially cause multiple hitTest calls on views across other pages.

I'm developing an iOS app that displays store locations on a map using Apple Maps (MapKit). I've limit the number of icons that can be displayed on the map to 100, but there's still huge performance issues and the app is very laggy even on modern iPhone models. What's the best practice when displaying a large number of icons on a map, should the icons be in PNG format with a small resolution (~10kb) or should the icons be vector (SVG) for best performance? Should I use the MapKit framework for iOS 17 or the UIKit approach?

I have a problem getting cg point from coordinate with MKsnapshotter. It works well with .flyover or .satellite map type but when using .satelliteFlyover cg point gets invalid value. Can you guys help me to get correct value? I attach screenshot here.

Using SwiftUI, MapKit and the Map() view in iOS 17, I'm adding markers and annotations to the map instance. However it seems regardless of what order they are added, they are rendered with random Z-index values. I've not found any modifiers to specify any kind of priority. Is there a way to declare Z-index priority of Marker and Annotation views?

I have more than 2000 location pins in SwiftData. My model like this: @Model class HaritaModel { let id: Int let sto_title: String let sto_latitude: Double let sto_longitude: Double let sto_address: String let sto_city: String let sto_country: String init(id: Int, sto_title: String, sto_latitude: Double, sto_longitude: Double, sto_address: String, sto_city: String, sto_country: String) { self.id = id self.sto_title = sto_title self.sto_latitude = sto_latitude self.sto_longitude = sto_longitude self.sto_address = sto_address self.sto_city = sto_city self.sto_country = sto_country } } I want to take the user's location and show them the pins at a certain distance. I want these pins to be dynamically updated when the user pan or zoom the map. The code I am trying to write is as follows: // // HaritaTest.swift // import SwiftUI import MapKit import SwiftData struct HaritaTest: View { @Environment(\.modelContext) private var contextHarita @Query private var harita: [HaritaModel] @State private var userPosition: MapCameraPosition = .userLocation(fallback: .automatic) @State private var userCoordinate: CLLocationCoordinate2D? var body: some View { Text("Total Boutique \(harita.count)") Map(initialPosition: { userPosition }) { haritaView in ForEach(harita) { point in if let userCoordinate = userCoordinate, let stoLatitude = point.sto_latitude, let stoLongitude = point.sto_longitude, let latitude = Double(stoLatitude), let longitude = Double(stoLongitude) { let coordinate = CLLocationCoordinate2D(latitude: latitude, longitude: longitude) if haritaView.contains(coordinate: coordinate) { MapPin(coordinate: coordinate) } } } } .onAppear { CLLocationManager().requestWhenInUseAuthorization() getUserLocation() } } private func getUserLocation() { if let userLocation = CLLocationManager().location { userCoordinate = userLocation.coordinate } } } struct HaritaTest_Previews: PreviewProvider { static var previews: some View { HaritaTest() } } can you support me? thanks in advance

Is there a possibility to enable the public transport layer like in the Maps app?

We're recently requested a Mapkit JS / Mapkit Server api limit increase request and are waiting to hear back before we push an important update to our app which switches to mapkit via server apis. We don't often go over the 25k daily limit, but there can be spikes where the app goes very viral and we'll need well over 25k – likely above 50k based on historic usage. I was wondering if there's any way to expedite our limit request? Or how do we get notified if our limit has been approved, is there any way to check? Would using one of our Code-level support requests (TSIs) be a good idea here? Thanks!

Any suggestions on how to display multi-polygons within MapKit for SwiftUI(https://developer.apple.com/documentation/mapkit/mappolygon)? At the moment it is not supported and only supported by MapKit for UIKit(https://developer.apple.com/documentation/mapkit/mkmultipolygon) . Any idea on how to bridge these over?

The code in this example to add a gradient to a map polyline from WWDC doesn't work. https://developer.apple.com/videos/play/wwdc2023/10043/?time=1360 The polyline is rendered as a solid colour from as the first colour in the given array. Does anyone have any suggestions? Code for convenience: let coordinates = [ CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194), CLLocationCoordinate2D(latitude: 37.3352, longitude: -122.0322), CLLocationCoordinate2D(latitude: 34.0522, longitude: -118.2437) ] let gradient = LinearGradient(colors: [.red, .green, .blue], startPoint: .leading, endPoint: .trailing) let stroke = StrokeStyle(lineWidth: 5, lineCap: .round, lineJoin: .round, dash: [10, 10]) var body: some View { Map { MapPolyline(coordinates: coordinates) .stroke(gradient, style: stroke) } }

If I load a map while my device is online, I can access this map offline via the default caching mechanism. I need to be able to identify if a map cache is unavailable when my device is offline and react accordingly. For example, if I am offline and I load a map and the cache is unavailable i.e the map tiles are greyed out, I want to display a message to the user. The AppKit delegate had a method to identify when a map loaded but I do not see an equivilient way of doing this in Map. Any ideas?

I need to mark areas on a map, but I have only the points and want to have map circles around the points, how is it possible to make the circles not overlap in color, just look as they were one form.

What I am trying to accomplish: Navigate to MapView defined in ProfileMapView. - This works In ProfileMapView, when calloutAccessoryControlTapped method is called Navigate from ProfileMapView when to another view: ProfileDetailsView- This is does not work //Calling ProfileMapview like this: @State var pins = [GpsData.MyEndPt]() ProfileMapView(locationPins: $pins) // ProfileMapView defined struct ProfileMapView: View { @Environment(\.managedObjectContext) private var viewContext @Environment(\.dismiss) var dismiss @State var tracking:MapUserTrackingMode = .follow @Environment(\.presentationMode) var presentationMode @Binding var locationPins: [GpsData.MyEndPt] var body: some View { TabView { NavigationView { ZStack { VStack (alignment: .leading){ MapView(locationPins: $locationPins) .ignoresSafeArea() } } //.edgesIgnoringSafeArea(.all) .safeAreaInset(edge: .bottom) { Color.clear .frame(height: 0) .background(.white) } } } struct MapView: UIViewRepresentable { @Binding var locationPins: [GpsData.MyEndPt] func makeUIView(context: Context) -> MKMapView { //... } func updateUIView(_ uiView: MKMapView, context: Context) { //... } func makeCoordinator() -> MapViewDelegate{ var del = MapViewDelegate() del.addEndPoints(endPoints: locationPins) return del } class MapViewDelegate: MKMapView, MKMapViewDelegate { let PINID:String = "MyEndPoint" var mylocationPins: [GpsData.MyEndPt] = [] @State var locationId: String? @State var providerType: String? public func addEndPoints(endPoints: [GpsData.MyEndPt]) { self.mylocationPins = endPoints self.removeAnnotations(endPoints) self.addAnnotations(endPoints) self.showAnnotations(endPoints, animated: true) } func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? { var mPin: MKMarkerAnnotationView? = nil let subtitleView = UILabel() for pin in self.mylocationPins { if (mPin == nil ) { mPin = MKMarkerAnnotationView(annotation: annotation, reuseIdentifier: PINID) mPin?.canShowCallout = true } else{ mPin?.annotation = annotation } mPin?.rightCalloutAccessoryView = UIButton(type: UIButton.ButtonType.detailDisclosure) subtitleView.text = "Target: " subtitleView.text! += String(pin.target) } mPin!.detailCalloutAccessoryView = subtitleView return mPin! } func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) { DispatchQueue.main.async { if let thumbnailImageButton = view.leftCalloutAccessoryView as? UIButton, let url = (view.annotation as? GpsData.MyEndPt)?.thumbnailUrl { print("URL: \(url)") do{ let imageData: Data = try Data(contentsOf: url as URL) let image = UIImage(data: imageData) thumbnailImageButton.setImage(image, for: UIControl.State.normal) }catch{ print("Unable to load image data: \(error)") } } } } //MARK:- delegate method func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) { if control == view.rightCalloutAccessoryView { mapView.deselectAnnotation(view.annotation, animated: true) for detail in self.mylocationPins { locationId = detail.locationId providerType = detail.providerType NavigationLink(value: control) { ProfileDetailsView(locationId: $locationId, providerType: $providerType) } break } } } } } } ProfileDetailsView defined like this: @StateObject var manager = LocationManager() @State var tracking:MapUserTrackingMode = .follow @Environment(\.presentationMode) var presentationMode @Binding var locationId: String? @Binding var providerType: String? var body:some View { VStack (alignment: .leading){ Text("Details here...") Button { } label: { Text("Share") .foregroundColor(.blue) } .buttonStyle(.bordered) Button { } label: { Text("Update consumption") .foregroundColor(.blue) } .buttonStyle(.bordered) } } } I get warning: "Accessing State's value outside of being installed on a View. This will result in a constant Binding of the initial value and will not update." inside ProfileMapView line wheer I define @Binding var locationPins: [GpsData.MyEndPt]. That value is being passed into ProfileMapView - so I dont know why then warning. However, ProfileMapView gets called, the mapview is displayed and the marker pin appears and when I click on the disclosure the navigation to other view ProfileDetailsView does not work. I tried NavigationStack and could not make it work because it threw lot of errors. How to fix the code in calloutAccessoryControlTapped method, so I can navigate to other view: ProfileDetailsView. I have spent a week on this trying various things but it hasn't worked.

Two separate app projects need maps or navigation: Offline map: offline vector map of small city needed within the app (avoiding any online connection after the app's install). Apple Maps requires map tile download after installation. What is an alternative solution? Navigation: An app with a list of locations where we don't want to build-in maps or navigation. Would it be possible to allow the user to click on a location, app copies GPS coordinates, and opens default iOS navigation app and navigates from there instead? Working in Xcode with Swift and SwiftUI.
