In my app, I am using geofencing to perform an action when the user enter or leaves a specified location. The geofencing (CLMonitor) is active permanently, and should work across multiple app sessions or after the device is restarted. It should also work after the app was minimized or terminated. This worked perfectly with iOS 17 and prior, but with iOS 18, things changed. As soon as iOS 18 dropped, users were informing me that the app does no longer perform the entry/exit action reliably (without me making any changes to the app). Most of the times, events are missed entirely. Sometimes, after the user opens or resumes the app, duplicate events are delivered and/or events with the current time instead of the correct time of entry/exit. I am making sure that the app has the "Always" location permission before geofencing is enabled The gefocence radius is between 20 and 500m, but even with the max. radius specified, the geofencing is unreliable For the same user and geofence, the entry/exit event is delivered occasionally, but not always I am currently not using CLLocationManager.allowsBackgroundLocationUpdates (even though it's documented as "Apps that receive location updates when running in the background must include the UIBackgroundModes key (with the location value) in their app’s Info.plist file") because it wasn't necessary on iOS 17 and in my tests, using it didn't yield any improvements In my search for what could have caused this change, I found this WWDC video about location authorization: . It appears that with iOS 18, it is now required to have an active CLServiceSession to ensure that location updates are delivered to my app. Even though the video is long (and I've watched it multiple times), some things are still unclear. For example, the docs state: If your app actively receives and processes location updates and terminates, it should restart those APIs upon launch in order to continue receiving updates. Also, in the video it is stated that: ... So your job, ..., is to make sure that your process launch logic knows what features it has been tasked with pursuing, and re-takes session objects... But on the other hand it's also said that: you can only start holding one (a CLServiceSession) when your app is in the foreground and also ... CLMonitor.events won’t yield results when it is not in use, unless a session which was started in the foreground, .... To summarize my questions, for the geofencing to work as described above: when exactly do I need to create a CLServiceSession if the app is launched into the backgorund? Immediately in the applicationDidFinishLaunching method, even though the app is still in the background (applicationState is background)? Or later on, when the app is opened again by the user, e.g. in applicationDidBecomeActive (and applicationState is active)? do I need to specify the background mode capability as noted in the Handling location updates in the background article? do I need to create a CLBackgroundActivitySession as noted in the Handling location updates in the background article? does it matter, which of the four initializer methods I am using to create the CLServiceSession (with CLServiceSessionAuthorizationRequirementAlways)? does it matter if I specify NSLocationRequireExplicitServiceSession in the Info.plist or not when I already do ensure that the app has the "Always" location permission when the feature is being enabled Does a CLServiceSession last indefinitely and should it only be invalidated once the user disables the feature?

We are currently experiencing a very interesting issue when accessing the location in the background with CLLocationManager. The user has given our app the "whenInUse" permission for locations and in most cases the app provides location updates even when it's in the background. However, when we started to use other navigation apps in the foreground we saw that the func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) method was called with (kCLErrorDomain error 1.). The user hasn't changed the location permission and we saw that locations were delivered once the user opened the app again. I don't see anything in the documentation explaining this issue, but I chatted with other developers that confirm that specific behavior. Am I missing something here?

Since iOS 26, the Apple Maps share sheet no longer provides a com.apple.mapkit.map-item attachment when sharing a location to my Share Extension. Additionally, on real devices the shared URL is now a short link (https://maps.apple/p/...), which does not contain coordinates. On the simulator, the URL still includes coordinates (as in previous iOS versions). I'm trying to find the official or recommended way to extract coordinates from these new short URLs. Environment: Devices: iPhone (real device) on iOS 26.0 / 26.0.1 Simulator: iOS 26.0 / 26.0.1 simulator (behaves like iOS 18 — see below) App: Share Extension invoked from Apple Maps -> Share -> my app Xcode: 26.0.1 Steps to Reproduce Open Apple Maps on iOS 26 (real device). Pick a POI (store/restaurant). Share -> choose my share extension. iOS 18 and earlier (lldb) po extensionContext?.inputItems ▿ Optional<Array<Any>> ▿ some : 1 element - 0 : <NSExtensionItem: 0x60000000c5d0> - userInfo: { NSExtensionItemAttachmentsKey = ( "<NSItemProvider: 0x600002930d20> {types = (\"public.plain-text\")}", "<NSItemProvider: 0x600002930c40> {types = (\"com.apple.mapkit.map-item\")}", "<NSItemProvider: 0x600002930bd0> {types = (\"public.url\")}" ); } Typical URL: https://maps.apple.com/place?address=Apple%20Inc.,%201%20Apple%20Park%20Way,%20Cupertino,%20CA%2095014,%20United%20States&coordinate=37.334859,-122.009040&name=Apple%20Park&place-id=I7C250D2CDCB364A&map=explore iOS 26 (lldb) po extensionContext?.inputItems ▿ 1 element - 0 : <NSExtensionItem: 0x6000000058d0> - userInfo: { NSExtensionItemAttachmentsKey = ( "<NSItemProvider: 0x600002900b60> {types = (\"public.url\")}", "<NSItemProvider: 0x600002900fc0> {types = (\"public.plain-text\")}" ); } URL looks like: https://maps.apple/p/U8rE9v8n8iVZjr On simulator iOS 26 same missing map-item provider - but the URL is still long and contains coordinates, like this: https://maps.apple.com/place?coordinate=37.334859,-122.009040&name=Apple%20Park&.. Issue The short URLs (maps.apple/p/...) cannot be resolved directly - following redirects ends with: https://maps.apple.com/unsupported The only way I've found to get coordinates is to intercept intermediate redirects - one of them contains the expanded URL with coordinate=.... Example of my current workaround: final class RedirectSniffer: NSObject, URLSessionTaskDelegate { private(set) var redirects: [URL] = [] func urlSession(_ session: URLSession, task: URLSessionTask, willPerformHTTPRedirection response: HTTPURLResponse, newRequest request: URLRequest) async -> URLRequest? { if let url = request.url { redirects.append(url) } return request } } Then I look through redirects to find a URL containing "coordinate=". This works, but feels unreliable and undocumented. Questions Was the removal of com.apple.mapkit.map-item from the Maps share payload intentional in iOS 26? If yes, is there a new attachment type or API to obtain an MKMapItem? What’s the official or supported way to resolve https://maps.apple/p/... to coordinates? Is there any MapKit API or documented URL scheme for this? Is intercepting redirect chains the only option for now? Why does the iOS 26 simulator still return coordinate URLs, while real devices don't?

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.

Summary CLLocationSourceInformation.isSimulatedBySoftware (iOS 15+) fails to detect location spoofing when using third-party tools like LocaChange, despite Apple's documentation stating it should detect simulated locations. Environment iOS 18.0 (tested and confirmed) Physical device with Developer Mode enabled Third-party location spoofing tools (e.g., LocaChange etc.) Expected Behavior According to Apple's documentation, isSimulatedBySoftware should return true when: "if the system generated the location using on-device software simulation. " Actual Behavior Tested on iOS 18.0: When using LocaChange sourceInformation.isSimulatedBySoftware returns false This occurs even though the location is clearly being simulated. Steps to Reproduce Enable Developer Mode on iOS 18 device Connect device to Mac via USB Use LocaChange to spoof location to a different city/country In your app, request location updates and check CLLocation.sourceInformation?.isSimulatedBySoftware Observe that it returns false or sourceInformation is nil Compare with direct Xcode location simulation (Debug → Simulate Location) which correctly returns true

I am encountering a coordinate rendering issue using MKMapView in my iOS app. I have a GPS coordinate in WGS84 format, which corresponds to a location in Hong Kong. When my device is physically located in Hong Kong, MKMapView displays the map with the "Apple Maps" label, and the WGS84 coordinate is rendered at the correct position. However, when the device is in Mainland China, MKMapView switches to display "Amap" (Gaode Maps) branding, and the same WGS84 coordinate is rendered at an incorrect position. I understand that Amap in Mainland China uses the GCJ-02 coordinate system, while Apple Maps typically uses WGS84. This discrepancy suggests a potential coordinate system mismatch, but I cannot definitively confirm which map type (and corresponding coordinate system) MKMapView is actually using in different regions. My key questions are: How can I programmatically or visually confirm the underlying map type (Apple Maps vs. Amap) and its coordinate system within MKMapView? Is there a way to simulate the Apple Maps environment for testing when physically located in Mainland China?

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.

Good morning everyone, I am developing a Flutter app for Android and iOS. When I press a button, the app detects the location of the device (obviously with permissions already granted). On Android everything works correctly. On iOS, however, when I press the button for the first time after opening the app, the location is detected after about 30-50 seconds. On the other hand, if I repeat the operation later, the response time is drastically reduced (only a few seconds). I am using the location package (https://pub.dev/packages/location), and the code to get the location is as follows: var currentLocation = await location.getLocation(); Has anyone experienced this problem before or knows how to solve it? Thank you very much! Federico

In the last few months we have seen a lot of the following errors in which it fails to retrieve location information. This seems to happen across multiple browsers and feels related to apple/mac OS more than the browsers. Error: "CoreLocationProvider: CoreLocation framework reported a kCLErrorLocationUnknown failure." Any suggestions or an ETA on when this can be fixed? I have seen other threads/posts on this but wanted a new one to highlight the issue is prevalent.

We developed an IMDF indoor map for a client (paid work) which we submitted to Apple a few months ago. Our client is wondering how many months the approval process will take. Also, we would like to get paid for the work. Any estimate from that team would be appreciated. Thank you

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.

Previously, when using AppDelegate, I was able to check the app’s launch options (launchOptions) to determine cases such as: Location updates (UIApplication.LaunchOptionsKey.location) Background push notifications (UIApplication.LaunchOptionsKey.remoteNotification) However, after migrating to the SceneDelegate approach, launchOptions is no longer available — it always returns nil. In my app, I need to branch the code depending on the launch options, but I can’t find a way to achieve this in the SceneDelegate environment. 👉 Is there a way to access launch options in SceneDelegate, similar to how it worked in AppDelegate? Or, if that’s no longer possible, what would be the proper alternative approach? Any guidance would be greatly appreciated.

I have the following code snippet with a simple map and map reader that shows a pin on the map when the user selects a location struct MapReaderTest: View { @State private var loc: CLLocationCoordinate2D? = nil var body: some View { MapReader { proxy in Map { UserAnnotation() if let loc { Marker(coordinate: loc, label: { Text("Marker") }) } } .onTapGesture { position in let position = proxy.convert(position, from: .local) loc = position } } } } This snippet compiles and works perfectly fine using Xcode version 16.4 building for iOS 18.0 and running on a device. This snippet also works for me when I build using Xcode 26 Beta and run in the canvas or simulator, however it does not work when I compile using Xcode 26 and run it on a physical device(I built and tested for both iOS 18.6 and iOS 26 Beta) Has anyone else had a similar issue / have any ideas for work arounds?

Our IMDF indoor maps submission is stuck on "Occupants data in review" for several months and I can't ahold of that team (their email doesn't work). I've been told they have a backlog, but the other steps were pretty fast. How long is the expected completion? Thank you!

Hi everyone, I’m building an iOS 18+ app in Xcode where Apple Maps is central. My goal is to start with the default Apple Maps experience (map view, search bar, pins, directions sheet, etc.) and then customize it for my project. I tried coding it from scratch using MapKit and SwiftUI, but I wasn’t able to get full parity with the basic features of the Maps app. My questions: Is there any sample project, template, or reference that provides the default Apple Maps functionality (views + interactions) as a baseline? Can I copy these into my Xcode project and then extend/customize them? If not, what’s the recommended best practice to get as close as possible to the native Maps app before adding my own features? Any guidance, sample code, or documentation links would be greatly appreciated.

My app is currently using CLGeocoder to get a CLPlacemark, then using placemark.postalAddress with CNPostalAddressFormatter to get an attributed string for the full address, I then enumerate its attributes to pull out specific elements like just the street or state or zip etc. This is deprecated in iOS 26 with MKReverseGeocodingRequest being the intended replacement. This API returns an MKMapItem which doesn’t provide a CNPostalAddress - you can get a full address as a String but not structured address data that I’m seeing. Am I missing some way to get the postal address? Or is it a non-goal to provide that anymore? Thanks!

Their support email is broken and our IMDF is stuck at "Occupants Data in Review" step. Thank you
