Hi, I have a SwiftUI Map with a set of three annotations. These annotations move around, and I would like to animate their movement from one coordinate to another, but I'm not finding a way to do that. I've tried using withAnimation { } when setting my array of Identifiable models that back the Annotations, and I've tried adding the .animation(.default, annotationModels) modifier to my Map object (where annotationModels is the array that backs my Annotations). The animation modifier doesn't work on Annotation structs, and it doesn't work if I add the animation modifier within the Annotation's view either. Does anyone have any suggestions on how I might be able to animate the coordinates of annotations using a SwiftUI Map? Does the problem have to do with the fact that I have an array of these annotations?

Hey, I have a problem. I was using MKMapView in my app, and in the view where I had a background at the top of the screen, in the example it was Color.red, it extended all the way to the top of the screen. Now, I wanted to switch to the newer Map and I'm seeing an issue because I'm getting a navigation bar that cuts off my color as I indicated in the picture. Does anyone know why this is happening and if there's another way to achieve this? Steps to reproduce: Change MapView() to Map() to see difference import SwiftUI import MapKit @main struct TestAppApp: App { var body: some Scene { WindowGroup { ContentView() } } } struct ContentView: View { var body: some View { NavigationStack { ScrollView(.vertical) { Color.red .padding(.top, -200) .frame(height: 200) MapView().frame(minHeight: 300) // change this line to Map } .navigationTitle("Title") .navigationBarTitleDisplayMode(.large) } } } private typealias ViewControllerRepresentable = UIViewControllerRepresentable struct MapView: ViewControllerRepresentable { typealias ViewController = UIViewController class Controller: ViewController { var mapView: MKMapView { guard let tempView = view as? MKMapView else { fatalError("View could not be cast as MapView.") } return tempView } override func loadView() { let mapView = MKMapView() view = mapView } } func makeUIViewController(context: Context) -> Controller { Controller() } func updateUIViewController(_ controller: Controller, context: Context) { update(controller: controller) } func update(controller: Controller) { } } #Preview { ContentView() } I got: I want:

Hello, There are some countries, with political conflicts on borders, does MapKit JS support displaying the map depending on the point of view of the region ? if yes, how technically is done (like adding an attribute region on request params or something else) ? Thanks

I have indoor map and I want to draw path between two route location ex. from A to B I want to draw ARKit based Arrow path in ios Application. Currently I am using ARAnchor to achieve this but challenges is if A to B is 10 meter and I am adding Nodes on each one meter so instead of 10 different nodes i am getting single Arrow nodes showing all 10 in it. I am using below code. // Below Code from where I am calling addArpath function if let lat1 = mCurrentPosition?.latitude, let long1 = mCurrentPosition?.longitude { let latEnd = steplocation.latitude let longEnd = steplocation.longitude // if let lastLat = arrpath.last?.latitude,let lastLong = arrpath.last?.longitude,let lastAltitude = arrpath.last?.altitude{ let userLocation = CLLocation(latitude: lat1, longitude: long1) let endLocation = CLLocation(coordinate: CLLocationCoordinate2DMake(CLLocationDegrees(latEnd), CLLocationDegrees(longEnd)), altitude: CLLocationDistance(steplocation.altitude), horizontalAccuracy: CLLocationAccuracy(5), verticalAccuracy: CLLocationAccuracy(0), course: CLLocationDirection(-1), speed: CLLocationSpeed(5), timestamp: Date()) let heading = getHeadingForDirectionFromCoordinate(from: userLocation, to: endLocation) let lon1 = degreesToRadians(long1) //DegreesToRadians(long1) let lon2 = degreesToRadians(longEnd); //DegreesToRadians(longEnd); let lat2 = degreesToRadians(latEnd); let dLon = lon2 - lon1 let y = sin(dLon) * cos(lat2); yVal = yVal + y // let distanceToendpoint = calculateDistance(lat: endLocation.coordinate.latitude, long: endLocation.coordinate.longitude) let distvalue = Int(distance) + Int(pathlength) distance += CGFloat(distvalue) for i in stride(from: 0, to: distance, by:1) { print("current loop iteration is:" ,i) let headingValue = heading - self.heading zValue = zValue + headingValue distanceVal = CGFloat(i) + distanceVal zGlobal = zValue // Calling addARPathtoLocation addARPathtoLocation(stepLocation:endLocation,zvalue: zValue, yvalue: yVal, distance:Float(i), direction: manuoverType) } // } } // MARK: - ARSessionDelegate func renderer(_ renderer: SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor) { guard !(anchor is ARPlaneAnchor) else { return } let sphereNode = generateArrowNodes(anchor: anchor) DispatchQueue.main.async { node.addChildNode(sphereNode) } } //create ARAnchor to add to nodes func generateArrowNodes(anchor: ARAnchor) -> SCNNode { let imageMaterial = SCNMaterial() imageMaterial.isDoubleSided = true imageMaterial.diffuse.contents = UIImage(named: "blueArrow") let plane = SCNPlane(width:0.5, height:0.5) plane.materials = [imageMaterial] plane.firstMaterial?.isDoubleSided = true let blueNode = SCNNode(geometry: plane) blueNode.name = "blueNode" blueNode.position = SCNVector3(x:Float(zGlobal), y:0, z:Float(distanceVal)) blueNode.eulerAngles.x = -.pi / 2 blueNode.eulerAngles.y -= Float(CGFloat(CGFloat.pi/4*6)) return blueNode } func addARPathtoLocation(stepLocation: CLLocation, zvalue: CGFloat, yvalue: CGFloat, distance:Float, direction:VMEManeuverType) { // give you the depth of anything ARKit has detected guard let query = sceneView.raycastQuery(from: sceneView.center , allowing: .estimatedPlane, alignment: .any) else { return } let results = sceneView.session.raycast(query) guard let hitResult = results.first else { print("No surface found") return } // Add ARAnchor to Scene let anchor = ARAnchor(transform: hitResult.worldTransform) sceneView.session.add(anchor: anchor) } func radiansToDegrees(_ radians: Double) -> Double { return (radians) * (180.0 / Double.pi) } func degreesToRadians(_ degrees: Double) -> Double { return (degrees) * (Double.pi / 180.0) } func getHeadingForDirectionFromCoordinate(from: CLLocation, to: CLLocation) -> Double { let fLat = degreesToRadians(from.coordinate.latitude) let fLng = degreesToRadians(from.coordinate.longitude) let tLat = degreesToRadians(to.coordinate.latitude) let tLng = degreesToRadians(to.coordinate.longitude) let deltaL = tLng - fLng let x = sin(deltaL) * cos(tLng) //cos(tLat) * sin(deltaL) let y = cos(fLat) * sin(tLat) - sin(fLat) * cos(tLat) * cos(deltaL) let bearing = atan2(x,y) let bearingInDegrees = bearing.toDegrees print("Bearing Degrees :",bearingInDegrees) // sanity check // let degree = radiansToDegrees(atan2(sin(tLng-fLng)*cos(tLat), cos(fLat)*sin(tLat)-sin(fLat)*cos(tLat)*cos(tLng-fLng))) if bearingInDegrees >= 0 { return bearingInDegrees } else { return bearingInDegrees + 360 } }

Hi all, It wasn't extensively covered in the "Unlock the power of places with MapKit" at WWDC, but is it possible to add your own views to the mapItemDetailAccessory? The default view is great, but I would like to add a button for opening a new window showing another view. The documentation is rather limited at the moment so I thought I would ask here. Thanks in advance.

I'm creating an app where I'm recreating how Apple Maps shows the user location button - i.e, in a stack with a background. I'd like the MapUserLocationButton to follow the styling that it does in Apple Maps (i.e., when locked to the user location, it switches to a filled icon, instead of colouring the background. Is there a way to do this?

I have been developing an app that includes some pinned locations. These are displayed on a map, and currently have the standard pins and SF Symbol pins. A few of the locations have a special symbol on Apple Maps, but the same symbol is not avalable in SF Symbols. I was wondering if it is possible to use the pins, other than the standard red, from Apple Maps.

I'm on MacOS 15 Beta and Xcode 16 Beta. Running iOS 18 Beta on a 15 Pro Max. I'm leveraging the .mapItemDetailSheet(item: input) option to pull up a sheet that displays the Place Card for a selection made from a List of places. What I'm seeing is that the first tap fails to pull up the sheet and it auto closes pretty much immediately. But then loads correctly on the second tap. Other times it will not auto close, but simply fail to load the item details in the sheet. Again, though, if I close the sheet and tap a second time it loads without issue. I'm posting to get some feedback as to whether this is most likely caused by bad code (I'm very new to this) or if it is known behavior and due to the Beta software. Any insight from the community would be helpful. Thanks in advance.

Hi. I want to make iOS app that when use camera AR, it can show someplace around me have annotations. ARGeoAnchor something but I don't have any idea. Can anyone give me some keywords? I can use Mapkit to search but don't know how to map it in AR.

I'm looking at the new beta features for MapKit in SwiftUI, does anyone know if it's possible to create a map annotation callout or popover from a custom view?

I hope to use SwiftUI and MapKit to achieve the effect of a globe view when zooming out on the map. The code works in Xcode’s simulator and Simulator, but when running on my iPhone, it only zooms out to a flat world map. I haven’t found anyone else encountering the same issue, so I’d like to ask where the problem might be. Below is the simple code: import SwiftUI import MapKit struct GlobalTest: View { var body: some View { Map(position: .constant(.automatic), interactionModes: [.all, .pan, .pitch, .rotate, .zoom]) { } .mapStyle(.hybrid(elevation: .realistic, pointsOfInterest: .including([.park]), showsTraffic: false)) } } #Preview { GlobalTest() } I have also tried setting the camera properties, but it still doesn’t work. My phone is an iPhone 15 Pro Max, running iOS 17.5.1, and I am in mainland China. The Xcode version is the latest. If anyone understands the reason, please let me know. This is very important to me, and I would be very grateful!

Edit: The issue was resolved. It's back up. I was streaming the new MapKit Places video, and it suddenly stopped. It's now missing from the Developer app and website. Is this intentional?

Description: I am working on an iOS 17 app using Xcode 15 and SwiftUI. The app involves displaying points of interest (POIs) on a MapView based on user proximity and other factors such as hours of operation. The data for the POIs is stored in a JSON file, which I am trying to import and parse in the project. However, I have encountered several issues: Deprecation Errors: When attempting to use MapAnnotation, I receive deprecation warnings and errors. It seems that MapAnnotation has been deprecated in iOS 17, and I need to use the new Annotation API along with MapContentBuilder. RandomAccessCollection Conformance: Errors related to RandomAccessCollection conformance when using Map with SwiftUI. JSON Import and Parsing: I used Bundle.main.url(forResource: "locations", withExtension: "json") to load the JSON file but faced issues with correctly parsing and mapping the JSON data to my model objects. What I Need: Guidance on how to correctly use the new Annotation API and MapContentBuilder for displaying POIs on a MapView in iOS 17. Best practices for importing and parsing JSON files in SwiftUI, especially for dynamically updating the MapView based on user proximity and other criteria like hours of operation. Any relevant code snippets or examples would be greatly appreciated. Example of What We Tried Model: swift Copy code struct POI: Codable, Identifiable { let id: Int let name: String let latitude: Double let longitude: Double let hours: [String: String] } Loading JSON: swift Copy code func loadPOIs() -> [POI] { guard let url = Bundle.main.url(forResource: "locations", withExtension: "json"), let data = try? Data(contentsOf: url) else { return [] } let decoder = JSONDecoder() return (try? decoder.decode([POI].self, from: data)) ?? [] } Map View: swift Copy code import SwiftUI import MapKit struct ContentView: View { @State private var pois: [POI] = loadPOIs() @State private var region = MKCoordinateRegion( center: CLLocationCoordinate2D(latitude: 40.7128, longitude: -74.0060), span: MKCoordinateSpan(latitudeDelta: 0.05, longitudeDelta: 0.05) ) var body: some View { Map(coordinateRegion: $region, annotationItems: pois) { poi in MapAnnotation(coordinate: CLLocationCoordinate2D(latitude: poi.latitude, longitude: poi.longitude)) { VStack { Text(poi.name) Circle().fill(Color.red).frame(width: 10, height: 10) } } } } } Issues Encountered: MapAnnotation is deprecated. Errors related to RandomAccessCollection conformance. Any advice or solutions for these issues would be greatly appreciated. Thank you!

Please note that for this app to be able show you your location on the map you need to enable it to ask for permission to track the user's location, in the project's targets' info: Here's also a video that illustrates the lag: https://youtube.com/shorts/DSl-umGxs20?feature=share. That being said, if you run this SwiftUI app and allow it to track your location, tap the MapUserLocationButton and press the buttons at the bottom, you'll see that the map lags: import SwiftUI import MapKit import CoreLocation struct ContentView: View { let currentLocationManager = CurrentUserLocationManager() let mapLocationsManager = MapLocationsManager() @State private var mapCameraPosition: MapCameraPosition = .automatic var body: some View { Map( position: $mapCameraPosition ) .safeAreaInset(edge: .bottom) { VStack { if mapLocationsManager.shouldAllowSearches { Button("First button") { mapLocationsManager.shouldAllowSearches = false } } Button("Second button") { mapLocationsManager.shouldAllowSearches = true } } .frame(maxWidth: .infinity) .padding() } .mapControls { MapUserLocationButton() } } } @Observable class MapLocationsManager { var shouldAllowSearches = false } // MARK: - Location related code - class CurrentUserLocationManager: NSObject { var locationManager: CLLocationManager? override init() { super.init() startIfNecessary() } func startIfNecessary() { if locationManager == nil { locationManager = .init() locationManager?.delegate = self } else { print(">> \(Self.self).\(#function): method called redundantly: locationManager had already been initialized") } } }; extension CurrentUserLocationManager: CLLocationManagerDelegate { func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) { checkLocationAuthorization() } }; extension CurrentUserLocationManager { private func checkLocationAuthorization() { guard let locationManager else { return } switch locationManager.authorizationStatus { case .notDetermined: locationManager.requestWhenInUseAuthorization() case .restricted: print("Your location is restricted") case .denied: print("Go into setting to change it") case .authorizedAlways, .authorizedWhenInUse, .authorized: // locationManager.startUpdatingLocation() break @unknown default: break } } } I've also tried in a UIKit app (by just embedding ContentView in a view controller), with the same results: import UIKit import MapKit import SwiftUI import CoreLocation class ViewController: UIViewController { let currentLocationManager = CurrentUserLocationManager() override func viewDidLoad() { super.viewDidLoad() currentLocationManager.startIfNecessary() let hostingController = UIHostingController( rootView: MapView() ) addChild(hostingController) hostingController.view.frame = view.bounds hostingController.view.autoresizingMask = [.flexibleWidth, .flexibleHeight] view.addSubview(hostingController.view) hostingController.didMove(toParent: self) } } extension ViewController { struct MapView: View { let mapLocationsManager = MapLocationsManager() @State private var mapCameraPosition: MapCameraPosition = .automatic var body: some View { Map( position: $mapCameraPosition ) .safeAreaInset(edge: .bottom) { VStack { if mapLocationsManager.shouldAllowSearches { Button("First button") { mapLocationsManager.shouldAllowSearches = false } } Button("Second button") { mapLocationsManager.shouldAllowSearches = true } } .frame(maxWidth: .infinity) .padding() } .mapControls { MapUserLocationButton() } } } } extension ViewController { @Observable class MapLocationsManager { var shouldAllowSearches = false } } class CurrentUserLocationManager: NSObject { var locationManager: CLLocationManager? func startIfNecessary() { if locationManager == nil { locationManager = .init() locationManager?.delegate = self } else { print(">> \(Self.self).\(#function): method called redundantly: locationManager had already been initialized") } } }; extension CurrentUserLocationManager: CLLocationManagerDelegate { func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) { checkLocationAuthorization() } }; extension CurrentUserLocationManager { private func checkLocationAuthorization() { guard let locationManager else { return } switch locationManager.authorizationStatus { case .notDetermined: locationManager.requestWhenInUseAuthorization() case .restricted: print("Your location is restricted") case .denied: print("Go into setting to change it") case .authorizedAlways, .authorizedWhenInUse, .authorized: // locationManager.startUpdatingLocation() break @unknown default: break } } } If you don't center the map in the user's location, you might see an occasiona lag, but it seems to me that this only happens once. How do I avoid these lags altogether? Xcode 15.4

I want to display an Apple map in my UIKit app, but if I try to do so with UIKit I get concurrency-related warnings (Xcode 15.4 with strict concurrency warnings enabled) that I couldn't find a proper solution to. So I opted for SwiftUI, and for the iOS 17 approach, specifically, (WWDC23). The following code displays a map with a marker. If you look at the Map initializer, you can see that a map camera position and a map selection are specified. If you run the app, however, you can't actually select the marker, unless you uncomment .tag(mapItem). import SwiftUI import MapKit struct MapView: View { @State private var mapCameraPosition: MapCameraPosition = .automatic @State private var mapSelection: MKMapItem? let mapItem = MKMapItem( placemark: .init( coordinate: .init( latitude: 37, longitude: -122 ) ) ) var body: some View { Map( position: $mapCameraPosition, selection: $mapSelection ) { Marker(item: mapItem) // .tag(mapItem) } .onChange(of: mapSelection) { _, newSelection in print("onChange") // never prints if let _ = newSelection { print("selected") // never prints } } } } If you give another tag, like 1, the code once again doesn't work. Is that really the way to go (that is, is my code with fine once you uncomment .tag(mapItem))? If not, how do I make a map with selectable MKMapItems in iOS 17? iOS 17.5, iPhone 15 Pro simulator, Xcode 15.4, macOS 14.5, MacBook Air M1 8GB.

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

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

I have generated a key for MapKit and it gave me a private key (p8), a Key ID and a MapKit JS key. I am trying to use MapKit in Delphi TMS FNC Maps but it does not seem to render the maps. The same code works with Google Map Key, but not Apple MapKit. I was told to use the MapKit JS key in TMS by the vendor, but neither the Key ID or the MapKit JS key worked. Any help on this is greatly appreciated. Thank you

I want to show what direction a user is facing (the blue cone that you get in Apple Maps), but I can't find a way to show it with SwiftUI. The closest I've found is this init signature for UserAnnotation: https://developer.apple.com/documentation/mapkit/userannotation/4235435-init But it only gives heading data once you press the map orientation button, to always show the forward direction. I want to show the cone in the normal map, without reorienting it.

I am trying to load and view several locations onto a map from a JSOPN file in my SwiftUI project, but I continually encounter the error "no exact matches in call to initializer" in my ContentView.swift file. What I Am Trying to Do: I am working on a SwiftUI project where I need to display several locations on a map. These locations are stored in a JSON file, which I have successfully loaded into Swift. My goal is to display these locations as annotations on a Map view. JSON File Contents: coordinates: latitude and longitude name: name of the location uuid: unique identifier for each location Code and Screenshots: Here are the relevant parts of my code and the error I keep encountering: import SwiftUI import MapKit struct ContentView: View { @State private var mapPosition = MapCameraPosition.region( MKCoordinateRegion( center: CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194), span: MKCoordinateSpan(latitudeDelta: 0.05, longitudeDelta: 0.05) ) ) @State private var features: [Feature] = [] var body: some View { NavigationView { Map(position: $mapPosition, interactionModes: .all, showsUserLocation: true) { ForEach(features) { feature in Marker(coordinate: feature.coordinate) { FeatureAnnotation(feature: feature) } } } .onAppear { POILoader.loadPOIs { result in switch result { case .success(let features): self.features = features case .failure(let error): print("Error loading POIs: \(error.localizedDescription)") } } } .navigationBarTitle("POI Map", displayMode: .inline) } } } struct FeatureAnnotation: View { let feature: Feature var body: some View { VStack { Circle() .strokeBorder(Color.red, lineWidth: 2) .background(Circle().foregroundColor(.red)) .frame(width: 20, height: 20) Text(feature.name) } } } I have not had any luck searching for solutions to my problems using the error messages that keep arising. Does anyone have any advice for how to move forward?
