Live Activity does not work as a proxy for CLBackgroundActivitySession
Hi, I've watched the WWDC video "Discover streamlined location updates" As detailed here: https://developer.apple.com/videos/play/wwdc2023/10180/?time=364 In order for my app to receive location updates in the background, the video states that I can either use a live activity or a CLBackgroundActivitySession My app has a live activity, however the location updates stop shortly (10 seconds, this is the normal "grace period" described) after backgrounding the app, even when the live activity is visible. If I acquire a CLBackgroundActivitySession, location updates continue in the background. I have reproduced this behavior in the Simulator in a barebones app for testing and confirmed that it's not working as described. My question is: Should I hold a CLBackgroundActivitySession even when I already have a Live Activity?

Uploaded Build Missing NSLocationAlwaysAndWhenInUseUsageDescription Key Despite this Key Being in the Info.plist File
Hey All! I keep receiving an email from Apple stating "You have a missing purpose string in your Info.plist" for the key "NSLocationAlwaysAndWhenInUseUsageDescription". The thing is, though, that we are setting that value within our build Info.plist. The data in that value is even reflected into the application after build, with the correct purpose string showing up when requesting location services. We currently do our builds via Azure Devops CI/CD, where we use xcodebuild for this process. The archive also generates an Info.plist without the location key, so I tried manually inserting it before deployment. Also no luck. Anyone else had this issue or know how to resolve it? Snippet to show how the location key is currently set during build: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>NSLocationWhenInUseUsageDescription</key> <string>Application uses location data for accurate maps display</string> </dict> </plist> Thanks!

In Safari's JavaScript geolocation, is altitude based on MSL or WGS84 ellipsoid?
Hello all, I'm trying to retrieve geolocation data on the web, but I'm having trouble with the altitude value, which seems to differ from what I get on Android. When using navigator.geolocation.getCurrentPosition in Safari, is the altitude value based on mean sea level, or is it ellipsoidal altitude based on the WGS84 ellipsoid? altitude (WebKit JS): https://developer.apple.com/documentation/webkitjs/coordinates/1631861-altitude altitude (Core Location): https://developer.apple.com/documentation/corelocation/cllocation/altitude ellipsoidalAltitude (Core Location): https://developer.apple.com/documentation/corelocation/cllocation/ellipsoidalaltitude If anyone has any insight into this topic I would greatly appreciate it!

Location Verification API's
Dear Apple Team, I am reaching out regarding the need for more sophisticated location verification APIs beyond basic IP lookup capabilities. As online fraud continues to evolve, IP-based geolocation has proven insufficient for many business use cases requiring accurate location verification. Would it be possible to discuss this proposal with your API development team? I believe this would be valuable for the entire iOS and macOS developer ecosystem while maintaining Apple's commitment to user privacy.

Navigation Directional Information Permissions
I am developing a navigation application. My goal is for this navigation app to also work in the background and provide the user with real-time directional updates. When apps request access to location services, users see a TCC (Transparency, Consent, and Control) prompt. This prompt allows the user to choose under what conditions the app can access location services (for example: “While Using the App”, “Always”, etc.). If the user selects the “While Using the App” option, can the navigation app still access location in the background and provide directional information to the user? Is something like this technically possible? Does Apple allow this behavior for navigation apps or similar use cases?

Working with visits and significant location changes following Core Location updates in iOS 17 and iOS 18
Hello, I'm working on an application that requires the use of significant location changes and visits, in addition to region monitoring and standard continuous location delivery (foreground and background). iOS 17 and iOS 18 introduced changes to how we can monitor distinct regions of interest (with CLMonitor) as well as receive location updates (with CLLocationUpdate). But I couldn't find any information regarding how to work with Significant location changes. Do we still need to create a location manager and call startMonitoringSignificantLocationChanges()? Where are the updates received in this case, in the locationManager(_:didUpdateLocations:) or in the liveUpdates async sequence? Visits. Same question here, for visit monitoring to work, do we still have to create a location manager then call startMonitoringVisits()? Where are the visits being notified? Still in locationManager(_:didVisit:) or in the liveUpdates asynchronous sequence? I just want to be sure I understand correctly how to use the updates, and if some features of Core Location still need to use a location manager and the delegate to receive the events. Maybe additional CLCondition will be added to cover both of these technologies as it seems highly related to monitoring conditions (significant location change, and visit). Thank you, Axel

Replacement for deprecated CLPlacemark.region?
Hello, I use CLGeocoder to get the CLLocationCoordinate2D and CLRegion for an address. Now that this is deprecated in OS 26, I don't see a replacement for that property on MKMapItem via MKMapItemRequest and PlaceDescriptor. I've filed FB19027378 on this issue. Basically I have some addresses that have a street address, and others that just have a city. With CLGeocoder, when geocoding just the city, the CLRegion was set such that I could show my map zoomed out just right. I'm not sure how to do that now. Thanks!

Problem receiving Remote Notification in the background after Review Rejected
I created an app. One if its functionalities is receive Remote Notification in the background, while app is monitoring Significant Location Changes (SLC). This functionality worked fine. I was receiving these notifications correctly. Sometimes instantly, sometime with small or large delay. And then I send the app for review. It was rejected with 3 remarks: The app or metadata includes information about third-party platforms that may not be relevant for App Store users, who are focused on experiences offered by the app itself (I wrote that app communication works both for iOS and Android.) The app declares support for audio in the UIBackgroundModes key in your Info.plist but we are unable to locate any features that require persistent audio. EULA (End User License Agreement) is missing for in-app purchases. After the rejection the app is no longer receiving these notifications. They are there, since the app receives them, when I open app, or significant location change is detected. It also works, when I run the app directly from Xcode (in debug mode), not from TestFlight nor in Sandbox. It seem to me like Apple somehow spoiled my background capabilities on purpose or accidentally. Is it possible? What can I do with it? Is it the case that I should just fix the review remarks and send the app back to review, and once the app passes it, it will work again? Or should I not count on it? Any suggestions? I asked Apple using: https://developer.apple.com/contact/topic/#!/topic/select but so far no response.

Sync Conflict Between Contacts & Maps, Possible Cross-App Link with Home App Issue
Pinned 2 homes address for the same contact Steps Initial check in Apple Maps No saved places or pinned addresses appear. Open Personal Contacts You have two addresses stored in your contact card: Main and Home. Pin & Edit “Main” You pinned the Main address in Maps. Refined the location on the map. Renamed it (but still saved under the type “My Home”). Open “Home” Address in Contacts Refined the location again. Changed the type to “My Home.” Attempted to rename, but no option to change the label. Final Saved Places View Shows two entries both called “Main.” Opening either of them displays the same details for the Home address. Saved Places list only shows the full address text, without the ability to rename them inside Maps. Results Both addresses appear duplicated with the same name (“Main”), even though they point to different underlying addresses. When selecting either entry, Apple Maps incorrectly shows the same Home address details. The Saved Places section does not allow renaming; it defaults to showing the full address string. Issues Identified Sync Conflict Between Contacts & Maps Apple Maps pulls labels/types from Contacts, but the edits don’t update consistently across apps. Duplicate Naming Bug Both “Main” and “Home” collapse into “Main” in Saved Places, making them indistinguishable. One-to-One Mapping Failure Regardless of which saved place you open, Maps shows the same Home entry, meaning the system isn’t correctly binding each saved place to its respective contact address. Renaming Limitation Apple Maps doesn’t allow renaming saved addresses directly — it relies on Contacts. Since Contacts only supports preset labels (Home, Work, School, etc.), custom naming is blocked.

CLMonitor init function causes app crash
I'm experiencing app crashes when calling the CLMonitor initialization function: let monitor = await CLMonitor("my_monitor") According to WWDC 2023: Meet Core Location Monitor, when creating a CLMonitor object with the same identifier, it should access the existing monitor without any mention of app crashes or buggy behavior. However, in my actual testing, attempting to create a CLMonitor object with the same identifier immediately causes an app crash. Here's part of the crash log: Last Exception Backtrace: 0 CoreFoundation 0x19c4ab21c __exceptionPreprocess + 164 (NSException.m:249) 1 libobjc.A.dylib 0x199945abc objc_exception_throw + 88 (objc-exception.mm:356) 2 Foundation 0x19b7a9670 -[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:] + 288 (NSException.m:252) 3 CoreLocation 0x1aa25cbb4 +[CLMonitor _requestMonitorWithConfiguration:locationManager:completion:] + 516 (CLMonitor.mm:516) 4 libswiftCoreLocation.dylib 0x22bf6085c CLMonitor.init(_:) + 488 (CLMonitor.swift:280) 5 libswiftCoreLocation.dylib 0x22bf604b9 <deduplicated_symbol> + 1 6 MiniPlengi 0x106372ec9 closure #1 in static CLMonitor.loplatMonitor.getter + 1 (CLMonitor+Extensions.swift:31) 7 MiniPlengi 0x1062ce325 0x106290000 + 254757 8 MiniPlengi 0x1062f6a29 specialized thunk for @escaping @isolated(any) @callee_guaranteed @async () -> (@out A) + 1 (/<compiler-generated>:0) 9 MiniPlengi 0x1062ce325 0x106290000 + 254757 10 libswift_Concurrency.dylib 0x1a7f75241 completeTaskWithClosure(swift::AsyncContext*, swift::SwiftError*) + 1 (Task.cpp:537) Furthermore, even though I've written code to create CLMonitor objects based on a singleton structure to handle these crash cases, the app still crashes: extension CLMonitor { static var loplatMonitor: CLMonitor { get async { struct Static { static var monitor: CLMonitor? static var initializationTask: Task<CLMonitor, Never>? } // If already initialized if let monitor = Static.monitor { return monitor } // If there's an initialization task in progress, wait for its result if let task = Static.initializationTask { return await task.value } // Create new initialization task let task = Task { let monitor = await CLMonitor("my_monitor") Static.monitor = monitor Static.initializationTask = nil // Clean up task after completion return monitor } Static.initializationTask = task return await task.value } } } Is the CLMonitor API still in a stabilization phase and not recommended for production release? I would appreciate guidance on the correct usage. If these issues are expected to persist, I'm wondering if I should continue using the existing CLCircularRegion API instead. Any insights or recommendations would be greatly appreciated.

[Regression] Core Location underground positioning inaccurate on iOS 26.1 beta (23B5044i)
Summary While parallel testing Core Location on the new iOS 26.1 beta (23B5044i), I observed what I believe to be a regression of the issue described here: https://developer.apple.com/forums/thread/779192 Specifically, user positioning underground subway stations is noticeably inaccurate on the beta, whereas the same scenarios remain accurate on the unupgraded device below. I work with the MTA (New York City) and work with the OP of that thread. Happy to provide additional testing or details if helpful. Please let me know what else you need. Test Info Riding NYCT from Wall St to 34th St Penn Station on the 2 train carrying two iphones Recording: https://limewire.com/d/dpTWi#pDC3GRYIdE Expected: Consistent underground positioning comparable to prior releases. Actual: Degraded/inaccurate underground positioning on iOS 26.1 beta. Test Devices Left Screen: iPhone 15 Pro Max - iOS 26.1 beta (23B5044i) Right Screen: iPhone 11 - iOS 18.6.2 (22G100) Blue dots show location set by CoreLocation. Red dot on iphone 11 shows the actual location of both devices as I was able to manually place while travelling through a station. Placement through tunnels is not easy to verify and not usually indicated. Timestamps Comparison of when train was actually observed in a station vs when 26.1 and 18.6.2 CoreLocation updated to the station Fulton St 1:48 iOS 26.1 correctly updates (correctly) 2:16 iOS 18.6.2 updates (28sec late) Park Place 4:12 train arrives 4:15 iOS 18.6.2 updates to ~near Park Place 5:04 iOS 18.6.2 updates to Park Place (correctly) 6:07 iOS 26.1 update to ~near Park Place (over 2 mins late) Chambers St 6:02 train arrives / iOS 18.6.2 updates (correctly) 6:14 iOS 26.1 updates to ~near Chambers 6:18 iOS 26.1 update to Chambers (correctly) Franklin St 6:52 train arrives 6:55 iOS 18.6.2 updates (correctly) x:xx iOS 26.1 does not update Canal St: 7:16 train arrives 7:18 iOS 18.6.2 updates (correctly) x:xx iOS 26.1 does not update Houston St 7:54 train arrives 8:00 iOS 18.6.2 updates (correctly) x:xx iOS 26.1 does not update Christopher St 8:37 iOS 26.1 presumably between Houston St and Christopher St 8:40 train arrives / iOS 18.6.2 updates (correctly) x:xx iOS 26.1 does not update 14 St 9:22 train arrives 9:28 iOS 18.6.2 updates (correctly) 11:01 as train departs station iOS 26.1 updates (1.5 mins late)

Associating App Clips to Apple Map Location
Question: Does anyone have experience or documentation on how to get an App Clip to show on Apple Maps for a location? What I've tried: I have tried to associate my App Clip with an Apple Maps location. We are working with a physical restaurant that has an Apple Maps location, our full app is listed there but not the App Clip. I've gone through the steps of setting up the Advanced App Clip Experience and giving it the location we want it associated with, and have gone through Apple Business Connect and done all the setup there to get the full app to show with the location, but the app clip still does not show. I've contacted Apple Support and they gave me the criteria of "The App Clip is hosted within the app" and "The app is associated to the same physical location". When asking for clarification with the first criteria they said they could help and closed the chat.

UIKit mapView color annotations
I have tried to make colored annotations in mapView (shown in the commented sections) but they always appear in black. Any help would be appreciated. func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? { let annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: "TempAnnotationView") annotationView.canShowCallout = true annotationView.rightCalloutAccessoryView = UIButton(type: .detailDisclosure) let configuration = UIImage.SymbolConfiguration(pointSize: 10, weight: .thin, scale: .default) if annotation.title == "Start" { // let config = UIImage.SymbolConfiguration.preferringMulticolor() // let image = UIImage(systemName: "flag.fill", withConfiguration: config) // // palette // let config2 = UIImage.SymbolConfiguration(paletteColors: [.systemRed, .systemGreen, .systemBlue]) // let image2 = UIImage(systemName: "person.3.sequence.fill", withConfiguration: config2) // // hierarchical symbols // let config3 = UIImage.SymbolConfiguration(hierarchicalColor: .systemIndigo) // let image3 = UIImage(systemName: "square.stack.3d.down.right.fill", withConfiguration: config3) // // color // let image4 = UIImage(systemName: "cone.fill")?.withTintColor(.systemRed, renderingMode: .alwaysTemplate) // annotationView.image = image4 annotationView.image = UIImage(systemName: "poweron", withConfiguration: configuration) } return annotationView }

Location Permission Popup Not Appearing in SwiftUI App
Hello everyone, I'm working on a SwiftUI app that requires location services, and I've implemented a LocationManager class to handle location updates and permissions. However, I'm facing an issue where the location permission popup does not appear when the app is launched. Here is my current implementation: LocationManager.swift: import CoreLocation import SwiftUI class LocationManager: NSObject, ObservableObject, CLLocationManagerDelegate { private let locationManager = CLLocationManager() @Published var userLocation: CLLocation? @Published var isAuthorized = false @Published var authorizationStatus: CLAuthorizationStatus = .notDetermined override init() { super.init() locationManager.delegate = self checkAuthorizationStatus() } func startLocationUpdates() { locationManager.startUpdatingLocation() } func stopLocationUpdates() { locationManager.stopUpdatingLocation() } func requestLocationAuthorization() { print("Requesting location authorization") DispatchQueue.main.async { self.locationManager.requestWhenInUseAuthorization() } } private func checkAuthorizationStatus() { print("Checking authorization status") authorizationStatus = locationManager.authorizationStatus print("Initial authorization status: \(authorizationStatus.rawValue)") handleAuthorizationStatus(authorizationStatus) } func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) { print("Authorization status changed") authorizationStatus = manager.authorizationStatus print("New authorization status: \(authorizationStatus.rawValue)") handleAuthorizationStatus(authorizationStatus) } private func handleAuthorizationStatus(_ status: CLAuthorizationStatus) { switch status { case .authorizedAlways, .authorizedWhenInUse: DispatchQueue.main.async { self.isAuthorized = true self.startLocationUpdates() } case .notDetermined: requestLocationAuthorization() case .denied, .restricted: DispatchQueue.main.async { self.isAuthorized = false self.stopLocationUpdates() print("Location access denied or restricted") } @unknown default: DispatchQueue.main.async { self.isAuthorized = false self.stopLocationUpdates() } } } func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { DispatchQueue.main.async { self.userLocation = locations.last } } func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) { print("Location manager error: \(error.localizedDescription)") } } MapzinApp.swift: @main struct MapzinApp: App { @UIApplicationDelegateAdaptor(AppDelegate.self) var delegate @StateObject private var locationManager = LocationManager() var body: some Scene { WindowGroup { Group { if locationManager.authorizationStatus == .notDetermined { Text("Determining location authorization status...") } else if locationManager.isAuthorized { CoordinatorView() .environmentObject(locationManager) } else { Text("Location access is required to use this app. Please enable it in Settings.") } } } } } Log input: Checking authorization status Initial authorization status: 0 Requesting location authorization Authorization status changed New authorization status: 0 Requesting location authorization Despite calling requestWhenInUseAuthorization() when the authorization status is .notDetermined, the permission popup never appears. Here are the specific steps I have taken: Checked the Info.plist to ensure the necessary keys for location usage are present: NSLocationWhenInUseUsageDescription NSLocationAlwaysUsageDescription NSLocationAlwaysAndWhenInUseUsageDescription Verified that the app's target settings include location services capabilities. Tested on a real device to ensure it's not a simulator issue. I'm not sure what I might be missing. Any advice or suggestions to resolve this issue would be greatly appreciated. Thank you!

Not getting User's location in Background Mode
We developed a app in which the I need the app to update the User's location even in background( even after terminating from the recent UI ), Currently I am receiving the location updates when the user has kept the app in open and if minimised, But I want that it should update the location even when it is removed from recent app (minimised UI)(after terminating the app) Is it possible to do so.???

How do simulate custom moving location
For some background, my app is a Flutter app and I have opened it in xcode to try the following, I can build and run it on a simulator from xcode as well. I want to be able to simulate custom moving locations for my app. I tried going to Debug -> Simulate Location like online tutorials show but it is all greyed out. I have location simulation enabled (I have tried changing the default location too): Within the simulator itself I only have the predefined routes or a custom static location with no option for a moving location. How can I simulate a custom moving location? If it isn't possible is there anyway to simulate the location for a Mac app as I can build the Flutter app for Mac as well?
