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!

Geolocation tracking for IOS apps using .net Maui
I'm working on an in-house iOS app designed to help users accurately track their routes during trips. Currently, I've implemented a method to track users when the app is open in the background. However, I'm facing challenges, as the tracking stops when the device is locked for more than 10 minutes. I'm looking for a solution to continuously track a user's geolocation, even if the app is closed or not in use. Specifically, I want to ensure uninterrupted tracking, especially when the device is locked. Here are some key points: Current Method: I'm currently using the Core Location method and a combination of background tasks and a repeating timer to fetch the user's location and update a log for geolocation tracking when the app is open in the background. Issues Faced: The tracking stops when the device is locked for more than 10 minutes. This limitation impacts the accuracy of the route tracking during longer trips. Objective: My goal is to achieve continuous geolocation tracking, even when the app is closed or not actively used, to provide users with a seamless and accurate record of their routes. Platform: The app is developed for iOS using the .net maui platform, and I'm seeking solutions or suggestions that are compatible with the iOS .net maui environment. If anyone has experience or insights into achieving continuous geolocation tracking on iOS, especially when the app is not in use or the device is locked, I would greatly appreciate the assistance.

GPS Coordinates with Photos
I am currently developing an application that requires access to GPS coordinates from photos on iOS. However, with the recent update to iOS 18 beta, I have encountered a challenge: I can only view photos within maps, and I am unable to access the GPS coordinates directly. Could you please provide guidance on how to enable or retrieve GPS coordinates from photos in the current iOS 18 beta version? Any insights or resources you could share would be greatly appreciated. Thank you for your assistance!

Intermittent MKLocalSearch.Request Failures with Amap Data Source
My app has been using MKLocalSearch.Request for keyword-based location searches, and it has worked smoothly for a long time. However, starting last Wednesday, I began receiving an error from MKLocalSearch.start: MKErrorDomain (error code 4). This issue only occurs when the network environment is based in mainland China (where the API uses the Amap data source). When the network switches to other regions and other Apple Maps data source is used, the error does not occur. Another complication is that the API doesn't always fail—certain keywords still work (for example, "Huawei"). Already filed a ticket in Feedback Assistant: https://feedbackassistant.apple.com/feedback/15544549

UIViewRepresentable & MVVM
I am trying to get my head around how to implement a MapKit view using UIViewRepresentable (I want the map to rotate to align with heading, which Map() can't handle yet to my knowledge). I am also playing with making my LocationManager an Actor and setting up a listener. But when combined with UIViewRepresentable this seems to create a rather convoluted data flow since the @State var of the vm needs to then be passed and bound in the UIViewRepresentable. And the listener having this for await location in await lm.$lastLocation.values seems at least like a code smell. That double await just feels wrong. But I am also new to Swift so perhaps what I have here actually is a good approach? struct MapScreen: View { @State private var vm = ViewModel() var body: some View { VStack { MapView(vm: $vm) } .task { vm.startWalk() } } } extension MapScreen { @Observable final class ViewModel { private var lm = LocationManager() private var listenerTask: Task<Void, Never>? var course: Double = 0.0 var location: CLLocation? func startWalk() { Task { await lm.startLocationUpdates() } listenerTask = Task { for await location in await lm.$lastLocation.values { await MainActor.run { if let location { withAnimation { self.location = location self.course = location.course } } } } } Logger.map.info("started Walk") } } struct MapView: UIViewRepresentable { @Binding var vm: ViewModel func makeCoordinator() -> Coordinator { Coordinator(parent: self) } func makeUIView(context: Context) -> MKMapView { let view = MKMapView() view.delegate = context.coordinator view.preferredConfiguration = MKHybridMapConfiguration() return view } func updateUIView(_ view: MKMapView, context: Context) { context.coordinator.parent = self if let coordinate = vm.location?.coordinate { if view.centerCoordinate != coordinate { view.centerCoordinate = coordinate } } } } class Coordinator: NSObject, MKMapViewDelegate { var parent: MapView init(parent: MapView) { self.parent = parent } } } actor LocationManager{ private let clManager = CLLocationManager() private(set) var isAuthorized: Bool = false private var backgroundActivity: CLBackgroundActivitySession? private var updateTask: Task<Void, Never>? @Published var lastLocation: CLLocation? func startLocationUpdates() { updateTask = Task { do { backgroundActivity = CLBackgroundActivitySession() let updates = CLLocationUpdate.liveUpdates() for try await update in updates { if let location = update.location { lastLocation = location } } } catch { Logger.location.error("\(error.localizedDescription)") } } } func stopLocationUpdates() { updateTask?.cancel() updateTask = nil } func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) { switch clManager.authorizationStatus { case .authorizedAlways, .authorizedWhenInUse: isAuthorized = true // clManager.requestLocation() // ?? case .notDetermined: isAuthorized = false clManager.requestWhenInUseAuthorization() case .denied: isAuthorized = false Logger.location.error("Access Denied") case .restricted: Logger.location.error("Access Restricted") @unknown default: let statusString = clManager.authorizationStatus.rawValue Logger.location.warning("Unknown Access status not handled: \(statusString)") } } func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) { Logger.location.error("\(error.localizedDescription)") } }

iOS 18 MapKit discrepancy between physical devices and simulators
I have noticed a discrepancy between behavior on physical devices and simulators in iOS 18. I am using the latest MapKit APIs to fetch MKMapItems using the following MKLocalSearch: private func performLocalSearch(_ query: String) async throws -> [MKMapItem] { let request = MKLocalSearch.Request() request.naturalLanguageQuery = query let search = MKLocalSearch(request: request) return try await search.start().mapItems } This returns an array of MKMapItem on both the simulator and physical device. The key difference is my physical device (iOS 18.1.1) is missing the MKMapItem's identifier value. On the simulator, identifier is always populated in addition to my search. Any ideas on how to resolve this? The new MapKit API for those curious: @available(iOS 6.0, *) open class MKMapItem : NSObject { @available(iOS 18.0, *) open var identifier: MKMapItem.Identifier? { get }

didEnterRegion and didExitRegion delegate methods are called twice
When I set the values of notifyOnExit and notifyOnEnter to true when registering CLCircularRegion, I checked that the didExitRegion and didEnterRegion functions are called well. However, there is a problem that they are called twice in a row every time they are called. I was wondering if this is an internal bug in the API. There is also a stackoverflow report related to the above issue. I would appreciate your confirmation. stackoverflow - why the didEnterRegion called twice? Thank you.

New CoreLocation APIs
Hi All, I am currently working on an app that has some navigation functionality, and since my minimum iOS is 18 wanted to incorporate the new APIs that yield a AsyncStream of locations. I have watched both WWDC sessions, the one where the new API is introduced to retrieve the location points, and also the other video where the new authorization process for location is simplified as well. I have an app currently working in its current state, but am noticing some weird quirks when using the CLBackgroundActivitySession to get the elevated background permission. What I am doing here is to create this stream and the background object is below: return AsyncThrowingStream { continuation in let task = Task { do { for try await update in CLLocationUpdate.liveUpdates(updateType) { if shouldStopUpdate { continuation.finish() break } continuation.yield(update) } } catch { continuation.finish(throwing: error) } } state = .started(locationTask: task, background: CLBackgroundActivitySession()) } When I have an active navigation session going and am strongly holding this object and the user force quits the app (or I stop the target through Xcode) the navigation activity indicator in the status bar (or dynamic island) remains present. Even if I relaunch the app, start navigation again, and then call the invalidate method on the CLBackgroundActivitySession I then am seeing that navigation indicator even if I delete my app, and often need to do a full restart to get out of this state. Is there a step I am missing, or do I not understand the way the new API works to run in the background?

How to correct business location?
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.

iOS 18: “Settings” button on location permission alert does nothing, logs BUG IN CLIENT OF UIKIT warning
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!

SwiftUI MapKit use of UserLocation struct
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?

Location not tracking in background
I really need some help. I have been going back and forth with a customer of mine for weeks. Our app is supposed to track location in the background after a user starts it in the foreground. Every time I test it, it works. I can put the app in the background and walk around for hours. Every time he tests it, it doesn't work. He puts the app into the background and about a minute later, it stops tracking him. Then it starts again when the app comes back to the foreground. We have each tried it on two devices with the same results. I'm willing to post the rest of the details if anyone is interested in helping me, but the last couple of times I got no response, so I'm not going to bother unless I can get some help this time. Thanks.

MapPolygon
I recently converted over my map from Mapbox Maps to MapKit Map. I have been able to add my polygons on the Map using MapPolygon. The issue I am having is being able to select the Polygon to be able to view information about the polygon. Has anyone been able to figure out a way to tap on the Polygon? I have tried selection but the Polygon doesn't recognize the tap. I would really appreciate it if anyone could point me in the right direction of how I can accomplish this.

Location Push Extension Cannot Wake after 10 mins
Hi team, I'm developing a feature that's collecting the device locations for home security app. We've been following https://developer.apple.com/documentation/corelocation/creating-a-location-push-service-extension apns-push-type set to location. apns-priority set to 5. during testing, we found that the device's notification extension cannot be triggered after device going into lock screen for 10 mins. Wonder should we set the priority to 10? Thanks!

How to update business information on Apple Maps Ukraine?
Hello everyone, I need help updating business information on Apple Maps for locations in Ukraine. Unfortunately, the usual methods, like "Report an Issue" in the Maps app or using Apple Business Connect, don’t seem to be working properly for Ukrainian businesses. Many locations have outdated or missing details, which is frustrating for both business owners and customers. Given the current situation, keeping information accurate is more important than ever. Has anyone successfully updated business listings in Ukraine recently? If so, could you share the process or any contacts that might help? Any advice would be greatly appreciated! Thanks in advance!

CarPlay map view stops updating when iPhone screen turns off
Hello all, I have a food delivery app that I am beginning to implement CarPlay support in. Route picking, navigation, turn-by-turn guidance features all work perfectly on iPhone, and on CarPlay while the iPhone is unlocked, or locked but screen on. However, when the iPhone is locked and the screen is off, the CarPlay map view stops following the user's location and appears to be frozen. When this happens, the other "map buttons" that are part of the CPMapTemplate continue to accept user input (I can enter and exit the map panning mode for example), the user's location continues to update, and the turn-by-turn guidance continues as normal. It appears to be just the map view (which is drawn on the window and is not part of the CPMapTemplate) that stops updating in this state. I've been through every page of Apple documentation on CarPlay but nothing references or addresses how to keep the CarPlay session active while the iPhone is locked. I'm not sure where else to look for answers and I'm out of theories as to why this might happen. Any guidance around this would be greatly appreciated.

Issue with calculating the distance between two points on a map
I have an error issue that I haven’t been able to solve despite doing extensive research. In fact the similar examples I have found so far have been educational but I have not been able to make work. The example below I am hoping will be easy to fix as it is only producing errors with one line of code… import SwiftUI import CoreLocation var currentLon = Double() var currentLat = Double() extension CLLocation { class func distance(from: CLLocationCoordinate2D, to: CLLocationCoordinate2D) -> CLLocationDistance { let from = CLLocation(latitude: from.latitude, longitude: from.longitude) let to = CLLocation(latitude: to.latitude, longitude: to.longitude) return from.distance(from: to) } func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { currentLon = (locations.last?.coordinate.longitude)! currentLat = (locations.last?.coordinate.latitude)! }/*⚠️ Not sure if this function will work? (Update User Location coordinates on the move?)*/ } struct Positions: Identifiable { let id = UUID() let name: String let latitude: Double let longitude: Double var coordinate: CLLocationCoordinate2D { CLLocationCoordinate2D(latitude: latitude, longitude: longitude) } } struct GameMapView: View { let from = CLLocationCoordinate2D(latitude: currentLon, longitude: currentLat) let to = CLLocationCoordinate2D(latitude: thisCardPositionLongitude, longitude: thisCardPositionLongitude) let distanceFrom = from.distance(from: to) /*⚠️ ERRORS: 1. Cannot use instance member 'from' within property initializer; property initializers run before 'self' is available. 2. Cannot use instance member 'to' within property initializer; property initializers run before 'self' is available. 3. Value of type 'CLLocationCoordinate2D' has no member 'distance'. */ @State private var region = MKCoordinateRegion( center: CLLocationCoordinate2D( latitude: thisCardPositionLatitude, longitude: thisCardPositionLongitude), span: MKCoordinateSpan( latitudeDelta: 0.0001, longitudeDelta: 0.0001) ) var body: some View { Map(coordinateRegion: $region, showsUserLocation: true, annotationItems: locations){ place in MapMarker(coordinate: place.coordinate,tint: Color.accentColor) } .edgesIgnoringSafeArea(.all) VStack { Print("Distance from Location: \(distanceFrom)") font(.largeTitle) padding() }

Background location indicator stuck in dynamic island when using CLServiceSession and CLBackgroundActivitySession
We have a setup that's really close to the one used in the example project - Monitoring location changes with Core Location. In short, we have a flag that indicates whether or not we should start background location monitoring. If the flag is on, after the app starts, we Create a CLServiceSession with authorization: .always Create a CLBackgroundActivitySession The user can perform an action (press a button) to toggle the flag off, in which case we invalidate and dispose of the CLServiceSession and CLBackgroundActivitySession instances and cancel any liveUpdates observation. So far, so good, everything works as expected. However, we're experiencing a weird behavior on iPhones with Dynamic Island after there's an app update. When the user is on the same app version, the behavior is correct. have the flag on, background location monitoring works fine, when the app is in the the background, there's correctly a location indicator in Dynamic Island the user can go back to the app and turn the flag off (disposing of instances, cancelling location observation), and when the app is in the background, there is no location indicator in Dynamic Island The problem arises when the user updates the app open version 1.0 of the app have the flag on, background location monitoring works fine, when the app is in the the background, there's correctly a location indicator in Dynamic Island download an app update - version 2.0 the app restarts, didFinishLaunchingWithOptions gets called again and we start the background services dynamic island indicator is correctly showing a location indicator the user goes into the app, toggles the flag off - turning location observation off, we dispose of everything now, when the app is moved to the background, there's still a location indicator in the Dynamic Island, even though we're no longer observing location The indicator is hard to get rid of, there are only 2 ways we've found restart the device, or uninstall the app The question is - is this a bug in the system? Or is there anything we should be doing actively after an app update? Thank you!
