mapItemDetailSheet Not Displaying Information
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. This is working great on my iPhone 15 Pro Max and my iPad Pro 13. I also have the Mac Catalyst option added under: Project \ General \ Supported Destinations If I launch the app from Xcode via the play button, the app functions fine on my MacBook Pro and I get logs in Xcode, etc. However, if stop the session in Xcode and attempt to run the same app on its own on my MacBook Pro, the mapItemDetailSheet does not populate with any information. Anyone have ideas on where the disconnect could be? Why would the sheet populate with data when ran from Xcode but not when ran on its own? Again, it runs fine on the iPhone and iPad. Any ideas would be helpful and appreciated.

mapItemDetailSheet Behavior Question
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.

Clarification on the correct use for CLServiceSession
While updating my app for iOS 18 I have run into some major issues with how CLMonitor and visit tracking are handled in the background. I have implemented the new CLServiceSession (i think) correctly. In my @main App struct's init method I call CLServiceSession(authorization: .always) to create a session. This is done in the foreground when the app is launched and also in the background. From what i understand this is the intended way to create a session as when the app is relaunched by the system the existing session is terminated a few moments later. What im seeing in iOS 18 vs iOS 17 is drastically less location updates being delivered to the app. i see around the same significant updates being delivered (around 1 per mile - 5 miles) but the CLMonitor.CircularGeographicConditions are being triggered at about 1 per 1 to 2 minutes regardless of the radius. When a zone is left the condition is removed in the background and a new condition is created at the next place it should be tracking. For visit tracking, it only reports a visit correctly about 10% of the time. my guess is the app is getting suspended and/or terminated and the CLServiceSession isn't correctly being reinitialized (or something completely different, i'm really not sure at this point) I would love some guidance as to the correct way to handle these updates in iOS 18. It is unclear if these are intentional limitations imposed in iOS 18, incorrect implementation on my part, or a bug in the betas. Note: startUpdatingLocation is not appropriate for this app as it is way too power hungry.

Places with MapKit Questions
Hello, I'm very interested in utilizing Place ID with MapKit. Reference: https://developer.apple.com/videos/play/wwdc2024/10097/ I do have some questions I've been unable to find in documentation or within the demo. Apologies in advance if they have been added since. Are place photos included with the call? It appeared so in the demo just want to make sure as I was unable to confirm in the documentation.) Are star ratings included with the Place ID? Reason: Looking for ways to display top/popular POI around a location. How do rate limits work? Can places be cached? (We're looking to keep saved/bookmarked POI cached to avoid pinging MapKit each time the app is used) How often is place data refreshed? For example if a new restaurant opens in town when will it be available to display. Can search provide place results by name (in and out burger) and by type (burgers in LA)? Would we have to pick one way or the other for search to work in this case? Thanks in advance.

CLMonitor.CircularGeographicCondition Not triggering when in background on iOS 18 B1
Our test devices running the Dev Beta 1 for iOS 18 no longer recieve updates from the CLMonitor async stream (for try await event in await monitor.events) when the app is in the background and suspended. This works fine in iOS 17. I only have one CLMonitor.CircularGeographicCondition active at any given time, they switch out dynamically in the background based on the user's location. Another thing is that visit tracking and significant location changes continue to work as expected in the background. I have submitted feedback (FB13883553) but I'm curious if this is an undocumented policy change or a bug.

SwiftUI+MapKit cannot display the globe view on iPhone.
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!

Did the Snapshot API authentication change too?
Previously (and still, according to the documentation) building a Map Snapshot URL required building the URL with all its parameters, and then signing it using your private key. However, the URL created via the "Create a map" tool simply appends the pre-generated token on the end of the URL. And if I build a URL and do the same thing - append the token, but do not create a signature - the snapshot is generated correctly. (Omitting the token leads to a "not authenticated" message). Is this a new, easier way to generate snapshots?

CoreLocation compass heading is wrong
We receive a complaint from a user that the compass heading in our paragliding app differs from the heading in Compass app (preinstalled on iOS). During our research, it was found that third-party apps show the wrong compass heading. We get the compass heading according to the documentation (https://developer.apple.com/documentation/corelocation/getting-heading-and-course-information#Get-the-current-heading): func locationManager(_ manager: CLLocationManager, didUpdateHeading heading: CLHeading) { magneticHeading = heading.magneticHeading trueHeading = heading.trueHeading } The video linked below shows our app and the third-party app getting the compass heading of 270 degrees, and Compass app (preinstalled) getting the compass heading of 30 degrees. https://drive.google.com/file/d/1HPMRWWq1E_bFYZVyCeqB2Fo-AfG4q9J7/view?usp=share_link This problem appears to the user unpredictably and the correct compass heading is shown by Compass app (preinstalled). He has iPhone 15 Pro Max and iOS 17.4.1. The presence of this problem is very critical as it can cause fatal accidents.

MapKit JS Not Showing Suburb where marker is located
I'm using MapKit JS to plot markers on a Map - so far so good. I've noticed that it doesn't always show the Suburb name for the location of the marker . Here's an example: The marker is located in Hornsby which isn't showing on the map. If I move the market to an adjacent suburb Wahroonga I get the following: Now Wahroonga isn't showing but Hornsby is showing. I'm trying to find if there's a control that determines when the suburb for the marker is shown or not but haven't been able to find anything so far. I would also like to know if I can control the visibility of suburb names at different zoom levels. If you look at this map you can see the names of various suburbs (Bondi, Bondi Beach, North Bondi etc): but when I zoom in one level these all disappear and I cannot easily locate which suburb the market is in: Is there a way to always show the suburb names so users can easily locate themselves on the map in reference to the suburbs that they might not be familiar with?

Importing json file and displaying POI's in Mapkit using Xcode 15 and swiftUI
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!

Apple Maps Server API invalid JWT token
Hello, I'm truing to use Maps Server API. I have: Created Maps Identifier and a Private Key Used token maker to create a JWT token. I also tried creating JWT token manually. After generating a JWT token I used Maps Server API Playground with my JWT and I can successfully use Maps Server API. The problem is that when I try to use my JWT in either JS code, Postman or curl request, I get "Invalid Token" error. Which is very strange, because I doubled checked everything dozen of times and JWT works in Apple's playground tool. Here's a request example: curl -si -H"Authorization: Bearer <jwt token>" "https://maps-api.apple.com/v1/geocode?q=Apple%20Park%2C%20Cupertino%2C%20CA" My token is valid for 1 year When generating JWT token I left "Domain restriction" field empty.

No pop up to ask a user’s location within the app in MacOS
I have a map tool app in MacOS which needs request Location permission to show MapUserLocationButton. During development, the request for permission can pop up for the first run in my mac, but when it comes to the Apple review(Submission ID: 11f52f82-1d54-481a-9eed-880521fda2b3), they never see that. My mac is Macbook air M2 2022, 14.5 (23F79). Of course, enable App Sandbox - Location and fill up the Privacy - Location When in Use Usage Description Code: // // LocationManager.swift // import MapKit @Observable class LocationManager: NSObject { static let shared = LocationManager() private let manager = CLLocationManager() var isReady: Bool = false var showingAlert = false // var location: CLLocationCoordinate2D? var isAuthorized: Bool { #if os(macOS) .authorized == manager.authorizationStatus #else .authorizedWhenInUse == manager.authorizationStatus #endif } private override init() { super.init() manager.delegate = self manager.desiredAccuracy = kCLLocationAccuracyBest setup() } private func setup() { isReady = isAuthorized #if os(macOS) if CLLocationManager.locationServicesEnabled() { checkStatus() } else { showingAlert = true } #else checkStatus() #endif } private func checkStatus() { switch manager.authorizationStatus { case .notDetermined: manager.startUpdatingLocation() #if os(macOS) #else manager.requestWhenInUseAuthorization() #endif #if os(macOS) case .restricted, .denied: showingAlert = true case .authorizedAlways, .authorizedWhenInUse: manager.startUpdatingLocation() #else // case .authorizedWhenInUse: // manager.requestLocation() #endif default: break } } } extension LocationManager: CLLocationManagerDelegate { func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) { isReady = isAuthorized guard isReady else { return } // manager.requestLocation() } func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) { } func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { // location = locations.last?.coordinate } }

Periodic background location polling for infrequently used app
My team and I would like to develop a mechanism that collects the user’s location a few times per day, to detect when the user travels to a different country, for the user’s convenience. The app is very likely going to be opened very rarely. The user would of course be made aware of why collecting the location a few times a day is desired - namely, saving them the effort of having to remember to open the app every time they travel. My question is the following: given that the app would rarely be interacted with, what is the best strategy for collecting the location? The goal is to handle scenarios where the OS might avoid sending location events or notifications to the app. I imagine that the backend might need to intervene and send the occasional push notification to remind the user to open the app from time to time. There are 3 strategies that I’m aware of: LocationManager’s startMonitoringSignificantLocationChanges Scheduling BGAppRefreshTasks Using silent push notifications scheduled by the server. Ideally, using a location push service extension Keeping in mind the “Background execution demystified” WWDC session, documentation, and other threads, I concluded the following: The first idea is probably the least suitable, since it probably requires the app to be opened often, and the location updates would not be sent by OS if the app has been terminated from the app switcher. The second approach would also suffer from infrequent use and termination. The third approach seems not to be affected as much by infrequent usage. I understand that the 3rd strategy might also lead to the OS omitting to wake up the app when it has been terminated by the user. How would you implement this mechanism?

MKLocalSearch missing Music Venues from response
I have created an MKLocalSearch request as follows: let reqVenue = MKLocalSearch.Request() reqVenue.naturalLanguageQuery = "Music Venue" reqVenue.resultTypes = .pointOfInterest reqVenue.region = .init(center: mockCoord, latitudinalMeters: 150, longitudinalMeters: 150) I have made sure mockCoord is the exact location coordinate of the example music venue I want to get back in the response. I have noticed that all Music Venues I can find on Apple Maps do not come back as results in MKLocalSearch. I would love an explanation as to why and what I can do to make them appear in MKLocalSearch results please! best, nick

Flickering after removing MapKit MapPolygons/Polylines
I'm using MapKit for SwiftUI and having an issue when conditionally rendering MapPolygons or MapPolylines. Removing these overlays after a previous render causes them to flicker sporadically in their previous location when a user zooms or moves the camera. The relevant code is as follows: Map(position: $cameraPosition, scope: mapScope) { MapPolygon(coordinates: selectedTileVertices) .stroke( Color(red: 1.0, green: 1.0, blue: 1.0, opacity: isTileSelected ? 1.0 : 0.0), style: StrokeStyle(lineWidth: 5, lineJoin: .round)) .foregroundStyle(selectedTile.color.opacity(0.0)) } A polygon is rendered around a coordinate that a user selects. Upon selecting a new coordinate, a new polygon should render and the old be completely removed from the map. In practice, the new polygon is rendered and the old initially removed, but upon zooming the old polygon flickers in and out of appearance. At some zoom levels the old polygon is completely visible again. The crux of the problem sees to be that I am using .mapStyle(.imagery(elevation: .realistic)). Upon switching to .hybrid all flickering behavior is gone. The flickering becomes worse when doing a lot of zooming/camera movement while the old polygon is rendered and then swapping to a new polygon, and is largely nonexistent if swapping to a new polygon at the same zoom level. I imagine this has something to do with the extra rendering optimizations for satellite imagery. Any help resolving this issue would be appreciated.

API Key for MapKit not working for Delphi/TMS
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

Apple Maps cannot route to Latitude & Longitude
I've started getting reports of this today and I am able to replicate it on my end but looking to see if anyone else can verify or if it's possibly regional to me (Canada). In Apple Maps (iOS or macOS), if you search a latitude and longitude -- for example: "49.110,-112.110" and search, it centers on the location as it always has and shows the "Directions" button. When you tap the directions button, I get "A route can't be shown because of a problem connecting to the server.". Alternatively, if you pass the coordinate in via Apple Maps URL (https://maps.apple.com/?daddr=49.110,-112.110) it will route but the route is no longer to those specific coordinates, Apple Maps alters them to some nearest known entity (in this case, the RM of Warner County). If you compare the suggested route end destination with the search results for specifically entering the coordinates, you will see they are different locations and mapping routes are not actually taking you to the coordinates anymore. In the last photo attached, the arrow points to where "49.110,-112.110" is actually located which tapping the "Directions" button cannot figure out a route because of a server issue. If you pass it in via URL, it changes the destination coordinates and begins a route quite a ways away from the intended coordinate. The problem started happening either this morning or last night. Can anyone else confirm this happens to them? Thanks, Mike
