The code below using LookAroundPreview works fine on iOS (showing the preview image with a button saying "Look Around" at the top to enter full screen with navigation), but on macOS (15.3) there is no button and no way to navigate the view. Is this a bug or is there something I need to do differently on macOS? I have also tried using AppKit with MKLookAroundViewController and I don't seem get the button to launch full screen there either. import SwiftUI import MapKit struct ContentView: View { var body: some View { LookAroundPreviewView(coordinate: CLLocationCoordinate2D(latitude: 37.33182, longitude: -122.03118)) .frame(width: 300, height: 200) } } struct LookAroundPreviewView: View { let coordinate: CLLocationCoordinate2D @State private var scene: MKLookAroundScene? @State private var errorMessage: String? var body: some View { Group { if scene != nil { LookAroundPreview(scene: $scene, allowsNavigation: true) } else if let errorMessage = errorMessage { Text("Error: \(errorMessage)") .foregroundColor(.red) } else { ProgressView("Loading Look Around Preview...") } } .task { do { let request = MKLookAroundSceneRequest(coordinate: coordinate) let fetchedScene = try await request.scene scene = fetchedScene } catch { errorMessage = error.localizedDescription print("Error loading Look Around scene: \(error)") } } } }

I have a map where I am using UserAnnotation() to show the user's location. Location permissions are handled elsewhere in the app. If the user has previously granted location permission, that is enough for the UserAnnotation() blue pin to appear. Otherwise, it just doesn't draw. So the Map already knows the user's permission and location without my code again requesting location etc. I was looking for a way to leverage the map's knowledge of the user's location and came across this struct as described in the Documentation for SwiftUI Mapkit public struct UserLocation { public var heading: CLHeading? public var location: CLLocation? } I thought this struct might expose the user's location, but how it is expected to be used or when it should populated is unknown from the point of the documentation. Would someone please share the purpose and use of this struct?

We are developers of a golf app designed to assist golfers on the course. A key feature of our app is displaying a map of each hole, and we are currently transitioning to using MapKit and camera functionalities for this purpose. However, we are encountering issues with the downloading of map tiles when using the default satellite imagery. We have tried several approaches to diagnose the issue: We have tried several things to diagnose the issue: We implemented the mapViewDidFailLoadingMap delegate method. But it is inconsistent, sometimes triggering offline errors even when map tiles are cached. We implemented, the mapViewDidFinishRenderingMap method, but it always returns false when offline or you won't get the callback. Which doesn't let us know that rendering tiles has failed. We would appreciate your guidance on the following specific questions: Does MapKit provide a way to confirm if a map tile has fully loaded? Is there a method to detect if a portion of the map hasn't loaded or if a tile request has failed? Can we determine whether a map tile is cached, and if so, how long it will remain cached, similar to Cache-Control HTTP headers? Is there a way to trigger the preloading of map tiles when we know the user has a good internet connection? Please see the sample project for steps to reproduce the issue. Thank you for any assistance!

Hello everyone, I’m encountering a problem on the latest iOS 18 related to location permissions. When the user denies location access, my app triggers the standard system prompt asking them to enable location from Settings. On iOS 17 and below, tapping the “Settings” button in this system alert would successfully navigate the user to my app’s Settings page. However, on iOS 18, nothing happens. Instead, I see the following warning in the Xcode console: Warning : BUG IN CLIENT OF UIKIT: The caller of UIApplication.openURL(:) needs to migrate to the non-deprecated UIApplication.open(:options:completionHandler:). Force returning false (NO). Important details and context: In my own code, I have already replaced all calls to openURL(:) with open(:options:completionHandler:). I searched the entire codebase for usage of openURL: and didn’t find any. The alert that appears is the system location alert (iOS-generated), not a custom UIAlertController. Thus, I have no direct control over the underlying call. On iOS 17 (and below), tapping “Settings” in the same system dialog works perfectly and takes the user to the app’s permission page. The console message implies that somewhere—likely inside the system’s own flow—the deprecated API is being called and blocked on iOS 18. What I’ve tried: Verified I am not calling openURL: anywhere in my code. Confirmed that UIApplication.openSettingsURLString works when I programmatically open it in a custom alert. Tested multiple times on iOS 17 and iOS 18 to confirm the behavior difference. Steps to reproduce: Install the app on a device running iOS 18 Beta. Deny location permission when prompted. Trigger a piece of code that relies on location (e.g., loading a map screen) so that the OS automatically shows its standard “Location is disabled” alert, which includes a “Settings” button. Tap “Settings.” On iOS 17, this navigates to the app’s Settings. On iOS 18 Beta, it does nothing, and the console logs the BUG IN CLIENT OF UIKIT warning. Questions: Is this a known iOS 18 bug where the system’s own alert is still using the deprecated openURL: call? If so, are there any workarounds besides presenting a custom alert that manually calls open(_:options:completionHandler:)? Thank you in advance. Any guidance or confirmation would be appreciated!

We are experiencing an issue where MKMapView appears red on the app builded with Xcode 16 and executed on iOS 18 simulator. Only the ground is affected and buildings or POIs stay normal color. Xcode 16.1 beta 3 shows same result. Is there any similar case?

My organization, Los Angeles Pierce College, rents space to "Topanga Vintage Market", which is a monthly weekend swap meet operation. Apple Maps shows the location as roughly 34.18715° N, 118.58058° W. However, this is the location of the campus Child Development Center, which provides child care services and is not open during the hours of the Topanga Vintage Market. The actual location should be in the adjacent large parking lot, roughly 34.18740° N, 118.57782° W. They do not have a physical building. How do I get this resolved? I am putting a campus mapping application into the App Store real soon now. There is also an entry for "ALC Taco Truck" about 34.18533° N, 118.57349° W, which as far as I know has not been on campus since Covid. Thanks in advance for any guidance you can provide.

I have developed a mobile app using SwiftUI that supports GoogleMaps. Now I am in the process of building a CarPlay application. I assume CarPlay only supports Apple MapKit, as I could not find any way to integrate the Google Maps. Below are few queries, Could you please guide me on how I can obtain the user's current location on the CarPlay app launch? Is there a way CarPlay can get the details from the mobile app(not pretty sure as its using Google Maps)? If the user is logged out from the mobile app, what is the flow in CarPlay? Do we have any standard login page asking user to login to the mobile app first? Is there any UI asking the user to capture the location in CarPlay? This is my first CarPlay app. Kindly guide me to a document or so that covers these details. Thanks a ton!!

Trying to use new Swift @Observable to monitor GPS position within SwiftUI content view. But how do I tie the latest locations to the SwiftUI Map's mapCameraPosition? Well ideally the answer could cover: How to fix this error - So get map tracking along with the User Position, but also How to include facility to turn on/off the map moving to track the user position (which I'll need to do next). So could be tracking, then disable, move map around and have a look at things, then click button to start syncing the mapcameraposition to the GPS location again Refer to error I'm embedded in the code below. import SwiftUI import MapKit @Observable final class NewLocationManager : NSObject, CLLocationManagerDelegate { var location: CLLocation? = nil private let locationManager = CLLocationManager() func startCurrentLocationUpdates() async throws { if locationManager.authorizationStatus == .notDetermined { locationManager.requestWhenInUseAuthorization() } for try await locationUpdate in CLLocationUpdate.liveUpdates() { guard let location = locationUpdate.location else { return } self.location = location } } } struct ContentView: View { var newlocationManager = NewLocationManager() @State private var cameraPosition: MapCameraPosition = .region(MKCoordinateRegion( center: newlocationManager.location?.coordinate ?? <#default value#>, span: MKCoordinateSpan(latitudeDelta: 0.25, longitudeDelta: 0.25) )) // GET ERROR: Cannot use instance member 'newlocationManager' within property initializer; property initializers run before 'self' is available var body: some View { ZStack { Map(position: $cameraPosition) Text("New location manager: \(newlocationManager.location?.description ?? "NIL" )") // works } .task { try? await newlocationManager.startCurrentLocationUpdates() } } } #Preview { ContentView() }

I have a test application I'm working on (so it's a fresh Xcode project under Sonoma - with older map code borrowed from another project). It is a macOS application. And in Obj-C. When the map window is opened the logs contain the following - I've been trying to hunt down and resolve. Thank you in advance for any clues/pointers. Failed to locate resource "default.csv" Failed to locate resource "satellite@2x.styl" Failed to locate resource "satellite@2x.styl" Failed to locate resource "satellite.styl" Failed to locate resource "satellite@2x.styl" Failed to locate resource "satellite@2x.styl" Failed to locate resource "satellite.styl" Failed to locate resource "satellite.styl" Couldn't find satellite.styl in framework, file name satellite.styl Authorization status: Authorized The application does have MapKit.framework included.

If I change MKMapView's .preferredConfiguration property from .realistic to .flat, or .mapType from .hybridFlyover to .hybrid, subsequent scrolling causes a crash: -[MTLDebugRenderCommandEncoder validateDrawIndexedPrimitives:indexCount:indexType:indexBuffer:indexBufferOffset:instanceCount:function:]:6179: failed assertion `Draw Indexed Primitives Validation indexBufferOffset(0) + (indexCount(864) * 2) must be <= [indexBuffer length] (12). For example, changing: mapView.preferredConfiguration = MKHybridMapConfiguration(elevationStyle: .realistic) to: mapView.preferredConfiguration = MKHybridMapConfiguration(elevationStyle: .flat) Then, scroll the map view, and it will crash. It is OK the other way around. Or change: self.mapView.mapType = .hybridFlyover to: self.mapView.mapType = .hybrid I've tried everything I can think of, including calling functions like these after the change: mapView.setNeedsDisplay() mapView.setRegion(self.mapView.region, animated: false) .mapType and .preferredConfiguration are settable properties, so they should be possible to change. I could create a new MKMapview, but I'd have to perfectly recreate the state which is not trivial and far from ideal. I'm just trying to work around the issue FB14553276 so my map tiles don't show tiling seems in 2D which is a new issue introduced with iOS 18. This potential workaround still shows the seems in 3D, but is better than always showing seems. Seems like whatever I do, I just can't defeat MapKit bugs and puts me in an impossible situation. :( I've submitted Feedback this issue: FB16153802 It seems like others are experiencing the issue: https://forums.developer.apple.com/forums/thread/730780

Loading tile overlays is slow even when the raster data is locally available on the device running iOS 18.2 and built with Xcode 16.2. In this video (https://3dtopo.com/superSlowTileLoading.mov) it takes 38 seconds to load tiles readily available on the device. Then, the whole screen flashes when tiles that are already drawn are redrawn, making for a very poor user experience. 38 seconds to load a dozen or so small images (512x512) stored locally on the device is simply unacceptable. I can't release a product like this that I've spent the last 1.5 years building and many years developing the maps themselves. This severe issue is new since I committed to basing my app on MapKit. Note that this issue does not occur with Apple's base map tiles. I created a Feedback Assitant case, FB16110803, for this issue. For the video, I disabled loading any tiles from the network and disabled loading any other data, such as polylines. Essentially all I am doing is loading the tiles stored on the device and returning them, such as: public func loadTile(at path: MKTileOverlayPath, result: @escaping (Data?, Error?) -> Void) { fetchData(forKey: key, failure: {error in result(nil, error)}, success: {data in result(data, nil)}) } open func fetchData(forKey key: String, failure fail: ((Error?) -> ())? = nil, success succeed: @escaping (Data) -> ()) { let path = self.path(forKey: key) do { let data = try Data( contentsOf: URL(fileURLWithPath: path), options: Data.ReadingOptions()) succeed(data) self.updateDiskAccessDate(atPath: path) } catch { if let block = fail { block(error) } } }

I'm doing a weather app, users can search locations for getting weather, but the problem is, the results only shows locations in my country, not in global. For example, I'm in China, I can't search New York, it just shows nothing. Here's my code: @Observable class SearchPlaceManager: NSObject { var searchText: String = "" let searchCompleter = MKLocalSearchCompleter() var searchResults: [MKLocalSearchCompletion] = [] override init() { super.init() searchCompleter.resultTypes = .address searchCompleter.delegate = self } @MainActor func seachLocation() { if !searchText.isEmpty { searchCompleter.queryFragment = searchText } } } extension SearchPlaceManager: MKLocalSearchCompleterDelegate { func completerDidUpdateResults(_ completer: MKLocalSearchCompleter) { withAnimation { self.searchResults = completer.results } } } Also, I've tried to set searchCompleter.region = MKCoordinateRegion( center: CLLocationCoordinate2D(latitude: 0, longitude: 0), span: MKCoordinateSpan(latitudeDelta: 180, longitudeDelta: 360) ), but it doesn't work.

Hi, I am having some troubles creating a "nested" RealityView content using MapKit attachment. I am building a visionOS app that has horizontal MapKit map as an attachment to RealityView. I want to display 3D pins on that map, therefore I am using native map annotation and inside of these annotations, I create a new RealityView just for the 3D pin. This worked completely fine, unitil I wanted to have those RealityViews interact with each other. By interaction of those RealityViews I mean that I wanted to group entities from the first "main" RealityViews content with the 3D pins using ModelSortGroupComponent. Why I want this? I want to make the map circular, that is not a problem. Problem is that when I move the map with 3D pins, these pins have their own RealityView space and are only bounded by volumetric window dimensions. What happes is that these pins float next to the map (shown on attached image). So I came up with this solution: create a custom "toroid" like 3D entity model that occludes the pins that go outside the map region. In order to occlude only the pins, I need to use ModelSortGroupComponent to group the "toroid" entity with 3D pins entities (as described in another forum thread). To summarize: need the content of the superior RealityView to interact with map attachment annotations RealityView content in order to group them. There might be of course another, better way to achieve my whole goal, so I would naturally appreciate any help or guidance. Image below showing 3D pins on circular map. Since pins RealityView does no know anything about other RealityViews, it just overlows and hangs in space until is cropped by volumetric window boundary. Simplified code: var body: some View { let modelSortGroup = ModelSortGroup(depthPass: .prePass) RealityView { content, attachments in var mainEntity = Entity() // My other entities here... if let mapAttachment = attachments.entity(for: "mapAttachment") { // Edit map properties, position, horizontal layout etc. mainEntity.addChild(mapAttachment) } // Create and add to content mask "toroid" entity mapMaskEntity. Use OcclusionMaterial() material. mapMaskEntity.components.set(ModelSortGroupComponent(group: modelSortGroup, order: 0)) // For all pins, somehow also set the group // 3DPinEntity.components.set(ModelSortGroupComponent(group: modelSortGroup, order: 1)) content.add(mainEntity) } attachments: { Attachment(id: "mapAttachment") { Map { ForEach(mapViewModel.clusters, id: \.id) { cluster in Annotation("", coordinate: cluster.coordinate) { MapPin3DView(cluster: cluster) } } } .clipShape(Circle()) } } } // MapPin3DView is an map annotation view that includes a model of 3D pin and some details like image etc., uses RealityView. struct MapPin3DView: View { var body: some View { RealityView { content in // 3D pin entities... } } }

Hi! I'm attempting to run the Quakes Sample App^1 from macOS. I am running breakpoints and confirming the mapCameraKeyframeAnimator is being called: .mapCameraKeyframeAnimator(trigger: selectedId) { initialCamera in let start = initialCamera.centerCoordinate let end = quakes[selectedId]?.location.coordinate ?? start let travelDistance = start.distance(to: end) let duration = max(min(travelDistance / 30, 5), 1) let finalAltitude = travelDistance > 20 ? 3_000_000 : min(initialCamera.distance, 3_000_000) let middleAltitude = finalAltitude * max(min(travelDistance / 5, 1.5), 1) KeyframeTrack(\MapCamera.centerCoordinate) { CubicKeyframe(end, duration: duration) } KeyframeTrack(\MapCamera.distance) { CubicKeyframe(middleAltitude, duration: duration / 2) CubicKeyframe(finalAltitude, duration: duration / 2) } } But I don't actually see any map animations taking place when that selection changes. Running the application from iPhone simulator does show the animations. I am building from Xcode Version 16.2 and macOS 15.2. Are there known issues with this API on macOS?

Try the following code on macOS, and you'll see the marker is added in the wrong place, as the conversion from screen coordinates to map coordinates doesn't work correctly. The screenCoord value is correct, but reader.convert(screenCoord, from: .local) offsets the resulting coordinate by the height of the content above the map, despite the .local parameter. struct TestMapView: View { @State var placeAPin = false @State var pinLocation :CLLocationCoordinate2D? = nil @State private var cameraProsition: MapCameraPosition = .camera( MapCamera( centerCoordinate: .denver, distance: 3729, heading: 92, pitch: 70 ) ) var body: some View { VStack { Text("This is a bug demo.") Text("If there are other views above the map, the MapProxy doesn't convert the coordinates correctly.") MapReader { reader in Map( position: $cameraProsition, interactionModes: .all ) { if let pl = pinLocation { Marker("(\(pl.latitude), \(pl.longitude))", coordinate: pl) } } .onTapGesture(perform: { screenCoord in pinLocation = reader.convert(screenCoord, from: .local) placeAPin = false if let pinLocation { print("tap: screen \(screenCoord), location \(pinLocation)") } }) .mapControls{ MapCompass() MapScaleView() MapPitchToggle() } .mapStyle(.standard(elevation: .automatic)) } } } } extension CLLocationCoordinate2D { static var denver = CLLocationCoordinate2D(latitude: 39.742043, longitude: -104.991531) } (FB13135770)

I've encountered a weird issue with the new Map for iOS 17. In my list, which includes a MapView among other elements, I've observed that with the new initializer, the top and bottom bars are persistently displayed. They don't hide and only appear when scrolling, as they should. This problem doesn't occur with the old, now-deprecated initializer. To illustrate this, I have two screenshots: one with the map enabled and the other with the map disabled, demonstrating the issue. Here is also my new Map code: struct MapListRowView: View { @Binding internal var location: LocationModel @State internal var user: Bool = true private var position: CLLocationCoordinate2D { .init(latitude: location.latitude, longitude: location.longitude) } private var isPad: Bool { UIDevice.current.userInterfaceIdiom == .pad ? true : false } var body: some View { Map(bounds: .init(minimumDistance: 1250)) { if user { UserAnnotation() } Annotation("", coordinate: position) { ZStack { Circle().fill().foregroundColor(.white).padding(1) Image(systemName: "mappin.circle.fill") .resizable() .foregroundColor(.indigo) }.frame(width: 20, height: 20).opacity(user ? .zero : 1.0) } } .frame(height: isPad ? 200 : 100) .cornerRadius(8) .listRowInsets(.init(top: -5, leading: .zero, bottom: -5, trailing: .zero)) .padding(.vertical, 5) .disabled(true) } }

I am trying to derive the Apple Place ID from a CLPlacemark (or via a MKMapItem derived from it) created via either CLGeocoder().reverseGeocodeLocation() or CLGeocoder().geocodeAddressString(). In many cases, the placemark returned from these functions contains detailed information (name, address, coordinates, etc), implying that the Apple Place ID is known, but the identifier is not present. The only way I have found to get a Place ID is via MKLocalSearch. Wondering if I am missing something here.

I have a map application that needs to show a line (representing a direct route) that is above everything, including annotations. This is important because the map has lots of annotations (possibly hundreds) and the line is representing a route from point to another. With that many annotations being on top the line / route is basically useless because you can't see it. I've looked at things like MKOverlayLevel but it only supports .aboveRoads or .aboveLabels. Is there a way to set the z-axis of a map overlay so that it truly is on top of everything else on the map, including annotations? And if not directly in MapKit, what other options might I have? Worth noting that I'm targeting 16.4 and above, so that's my limitation on this

Has anyone found a thread-safe pattern that can extract results from completerDidUpdateResults(MKLocalSearchCompleter) in the MKLocalSearchCompleterDelegate ? I've downloaded the code sample from Interacting with nearby points of interest and notice the conformance throws multiple errors in Xcode 16 Beta 5 with Swift 6: extension SearchDataSource: MKLocalSearchCompleterDelegate { nonisolated func completerDidUpdateResults(_ completer: MKLocalSearchCompleter) { Task { let suggestedCompletions = completer.results await resultStreamContinuation?.yield(suggestedCompletions) } } Error: Task-isolated value of type '() async -> ()' passed as a strongly transferred parameter; later accesses could race and Error: Sending 'suggestedCompletions' risks causing data races Is there another technique I can use to share state of suggestedCompletions outside of the delegate in the code sample?

I have ran into an issue that is illustrated by the code in the following GitHub repository. https://github.com/dougholland/ColorTest When a SwiftUI color originates from the ColorPicker it can be persisted correctly and renders the same as the original color. When the color originates from the MapFeature.backgroundColor, it is always rendered with the light appearance version of the color and not the dark appearance version. The readme in the GitHub repo has screenshots that show this. Any assistance would be greatly appreciated as this is affecting an app that is in development and I'd like to resolve this before the app is released. If this is caused by a framework bug, any possible workaround would be greatly appreciated also. I suspect it maybe a framework issue, possibly with some code related to the MapFeature.backgroundColor, because the issue does not occur when the color originates from the ColorPicker.
