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 }

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)") } }

According to the following article, the CLCircularGeographicCondition has a limit whereby only 20 conditions can be monitored by any single app. Monitoring the user’s proximity to geographic regions While I understand the rationale behind this limit, 20 conditions seems quite low for some apps. It would be good if an app could request that the user opt-in to allowing more conditions if they understand the impact this might have on the battery etc. I'm migrating an app presently to use CLCircularGeographicCondition instead of the now deprecated CLCircularRegion. It would be good if there were more guidance on how to use the new Core Location API's to monitor how many conditions are in use within an app and how they can be deactivated when no longer required, allowing the app to free up more of the 20 conditions available.

Sometimes, I receive old location data from the location manager.

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?

Can I integrate Timer along with liveUpdates(_:) in order to manipulate the frequency. Let say for example I need the user location ever 1 min. Is it possible to do so?

I encountered a crash in iOS 17 related to CLBackgroundActivitySession, which appears to be due to misleading guidance in an Apple’s WWDC video. Crash sample code: https://github.com/steve-ham/AppleLocationCrash Simplified Reproduction Steps: 1. Open the GitHub sample app. 2. Archive and export (Distribute App -> Custom -> (Release Testing, Enterprise, or Debugging) -> Export). 3. Open the app. 4. Tap enableBackgroundLocation -> select Allow While Using App on the system popup. 5. Tap disableBackgroundLocation. 6. Go to the iOS home screen. 7. Wait for 10 seconds. 8. Reopen the app -> crash occurs. The crash happens because setting CLBackgroundActivitySession to nil does not end the session, despite Apple’s guidance suggesting it should. Below is the exact quote from WWDC 2023, which explicitly states that both calling invalidate() or letting the object get destroyed (i.e., setting to nil) would end the session: WWDC 2023 Discover Streamlined Location Updates (https://developer.apple.com/videos/play/wwdc2023/10180/) “Before starting the updates, you should instantiate a CLBackgroundActivitySession object to start a new session. Note, we are assigning the session to self.backgroundActivity, which is a property and not to a local variable. And this is important because if we used a local variable, then when it goes out of scope, the object it holds would be deallocated, invalidating the session and potentially ending your app’s access to location. Then when we want to end our session, we can do that by sending the invalidate message or by letting the object be destroyed.” I’ve submitted this to Apple for resolution but wanted to share this with the community. This misguidance has caused issues in my app’s release. If Apple could reply to confirm or provide clarification, it would be greatly appreciated. P.S. Even a minimal implementation in viewDidLoad triggers the crash: let session = CLBackgroundActivitySession() print("session (session)")

Hi, Have been trying to work with MapkitJS for a website, but I'm stumped on once basic capability: I want to be able to click on a point of interest, and perform some actions such as: Get its coordinates Attach an annotation to it (e.g. a callout) In my code, PointOfInterest's are selectable: map.selectableMapFeatures = [ mapkit.MapFeatureType.PointOfInterest, ]; But when I click on one, I do see the marker pop up but nothing else (which is not much help since there is no additional information in the marker itself). I see no event getting triggered that I can do something with. I am using an event listener as follows: map.addEventListener('single-tap', (event) => { const coordinate = map.convertPointOnPageToCoordinate(event.pointOnPage); console.log('Map tapped at:', coordinate); console.log('Map tapped event:', event); ... I guess I have to grab the Place ID somehow but I don't know how to. Thanks for any help.

We have to draw polygons inside a MKMapView based on coordinates retrieved from external source. It seems that MapKit does not behave correctly where polygons have single-vertex self-intersection. Here it's a simple point list example (every element is a pair of latitude and longitude values): [(0, 0), (20, 0), (10, 10), (20, 20), (0, 20), (10, 10), (0, 0)] The next image shows the rendering issue. But if the list is slightly changed in this way [(0, 0), (20, 0), (10, 10), (20, 20), (0, 20), (15, 10), (0, 0)] the issue disappears. The next image shows it. So it's not a self-intersection and self-tangency problem, but we think single-vertex self-intersection is a buggy edge case for MapKit. Right now we fixed this problem by finding the duplicated coordinates and applying a small offset (1e-8) to one of them, but it's a temporary solution and adds rendering delay. The problem is not due to iOS versions, since iOS 17 and 18 have the same issue. Also it happens on simulators and real devices. Here is the playground example, based mostly on the "Map Playground" template Xcode offers. If you run it without modifying it, the playground shows the "bugged" polygon. If you use notBugPoints instead of the default bugPoints for the polygon, the playground shows the "not-bugged" polygon. import MapKit import PlaygroundSupport // Create an MKMapViewDelegate to provide a renderer for our overlay class MapViewDelegate: NSObject, MKMapViewDelegate { func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer { if let overlay = overlay as? MKPolygon { let polygonRenderer = MKPolygonRenderer(overlay: overlay) polygonRenderer.fillColor = .red return polygonRenderer } return MKOverlayRenderer(overlay: overlay) } } // Create a strong reference to a delegate let delegate = MapViewDelegate() // Create an MKMapView let mapView = MKMapView(frame: CGRect(x: 0, y: 0, width: 800, height: 800)) mapView.delegate = delegate // Configure The Map elevation and emphasis style let configuration = MKStandardMapConfiguration(elevationStyle: .realistic, emphasisStyle: .default) mapView.preferredConfiguration = configuration // Create an overlay let bugPoints = [ MKMapPoint(CLLocationCoordinate2DMake(0, 0)), MKMapPoint(CLLocationCoordinate2DMake(20, 0)), MKMapPoint(CLLocationCoordinate2DMake(10, 10)), MKMapPoint(CLLocationCoordinate2DMake(20, 20)), MKMapPoint(CLLocationCoordinate2DMake(0, 20)), MKMapPoint(CLLocationCoordinate2DMake(10, 10)), MKMapPoint(CLLocationCoordinate2DMake(0, 0)) ] let notBugPoints = [ MKMapPoint(CLLocationCoordinate2DMake(0, 0)), MKMapPoint(CLLocationCoordinate2DMake(20, 0)), MKMapPoint(CLLocationCoordinate2DMake(10, 10)), MKMapPoint(CLLocationCoordinate2DMake(20, 20)), MKMapPoint(CLLocationCoordinate2DMake(0, 20)), MKMapPoint(CLLocationCoordinate2DMake(15, 10)), MKMapPoint(CLLocationCoordinate2DMake(0, 0)) ] let polygon = MKPolygon(points: bugPoints, count: notBugPoints.count) mapView.addOverlay(polygon) // Frame our annotation and overlay mapView.camera = MKMapCamera(lookingAtCenter: CLLocationCoordinate2DMake(10, 10), fromDistance: 5000000, pitch: 0, heading: 0) // Add the created mapView to our Playground Live View PlaygroundPage.current.liveView = mapView

On iPhone, we can use iBeacon to wake up the APP in the background for Bluetooth scanning connection, now we want to port the function to AppleWatch APP, but the API related to iBeacon is not applicable on watchOS, does watchOS have a similar wake up mechanism?

We create new development maps for builders and developers. Is it possible for us to add the new streets and addresses to Apple Maps so that visitors can find these brand-new streets and addresses?

I have an application that uses geolocation to track the user’s location and trigger actions when the app is in either the foreground or background. Currently, it seems that region entry is not triggered unless an app like Maps (which actively uses location services) is opened. The location permissions are correctly set to “Always” with precise location enabled. We are using geofencing to setup region and trigger actions when entering or leaving. Is there something I’m missing in the configuration that could be preventing region monitoring from triggering properly when the app is in use or in background?

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

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?

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!

Hello. I’m trying to use Core Location Service on any application in Mac (Safari, Maps, Weather, Chrome with Core Location configuration, or just trigger the API with a standalone app) and it seems that all of them constantly fail to provide the geolocation of my device because of the same error (kCLErrorLocationUnknown). I'm using MacBook Pro (M3 Max) with Sonoma 14.7. I’m sure the apps have access in the settings and everything is in order except the Core Location response. I’ve tested the issue on multiple MacBooks and it reproduced 100% of the times on all of them. Did anyone encounter a similar issue?

Hi, Where can I get more information on expected behaviour for the liveUpdates() configuration options, .default, .automotiveNavigation, .fitness, .automotive, .otherNavigation? Looking for expected accuracy, frequency of updates, non/stationary transition, etc. Thanks

Scrolling and zooming I have two apps that utilize the Apple Maps and since I updated my xcode to use IOS18, some of the functionalities have either been missing or glitching, and when I roll back to IOS17.5, everything seems to work fine. When I use MKMapView and use mapView.isZoomEnabled = true mapView.isScrollEnabled = true Scrolling and zooming is still not working on IOS18 but IOS17.5 works fine. Clicking on custom annotations When I press on a custom annotation I add to the MapView, the gesture is sometimes recognized and most of the times not recognized. If I have 20 annotations, there is a possibility only 2 of them respond to tap gestures. Below is how I define the annotation. Annotation("Pin", coordinate: CLLocationCoordinate2D(latitude: latitude, longitude: longitude), anchor: .bottom) { Button(action: {print ("Pressed annotation"){ CustomPin() } }

I updated my phone 14 pro to ios 18 and I faced issue with GPS. it’s show me in next Country and after minutes or hours it’s moved to the correct location how is it can fix it

Hello everyone, I’m facing an issue with my iOS app where the GPS/location services icon appears in the status bar immediately when the app is launched, even though I’m not intentionally accessing location services at that point. Issue Summary: • GPS Icon Activation: When I launch my app, the GPS icon turns on. It turns off when the app is minimized or closed. • No Intentional Location Usage at Launch: I have ensured that no instances of CLLocationManager are created when the app is launched. What I’ve Tried So Far: 1. Checked Controllers and Related Classes: • Reviewed all the code for the controllers that are active at launch. • Verified that none of these controllers create instances of CLLocationManager or call location-related methods. 2. Commented Out startUpdatingLocation: • Commented out all calls to startUpdatingLocation throughout the entire project. 3. Ensured No CLLocationManager Instances at Launch: • Searched for any code that might instantiate CLLocationManager during app launch. • Confirmed that no such instances are being created. 4. Commented Out Google Maps SDK Configuration: • In AppDelegate, commented out the Google Maps SDK configuration, so it’s not initialized with the API key. • No map views (GMSMapView, MKMapView) are initialized or used when the app is launched. 5. Tested Location Permissions: • When I change the location permission for the app to “Never” in the Settings app, the GPS icon does not appear upon app launch. • This suggests that the app is accessing location services when it has permission, even though I haven’t explicitly requested it at launch. Objective: • Control GPS Activation: I want to ensure that the GPS does not turn on when the app is launched. I intend to activate location services only when needed later in the app. Request for Assistance: I’m seeking guidance on the following: 1. Debugging Techniques: • How can I trace the code that’s causing the GPS to turn on at app launch? • Are there tools or methods to identify hidden or indirect calls to location services? 2. Forcing Location Services Off at Launch: • Is there a way to programmatically prevent location services from activating during app launch? • Can I defer any implicit location service initialization until I explicitly enable it? 3. Potential Hidden Triggers: • Are there known scenarios where location services could be activated without direct use of CLLocationManager? • Could frameworks like Google Maps SDK trigger location services even if not fully initialized? 4. Additional Suggestions: • Any other insights or suggestions to prevent the GPS icon from appearing on app launch. Additional Information: • Third-Party Frameworks: • I have not removed third-party frameworks yet, as I wanted to check other possibilities first. • Open to the idea that a third-party framework might be causing this, but need guidance on how to confirm. • Code Availability: • I’m happy to provide specific code snippets if that would help diagnose the issue. Environment: • Xcode Version: Xcode 15.4, Xcode 16.0 • iOS Deployment Target: iOS 15.0 • Devices Tested: iPhone SE 2nd and 3rd gen, iPhone 15, iPhone 15 pro, iPhone 11 • Programming Language: Swift What I’m Looking For: • Assistance in tracing the cause of the GPS activation on app launch. • Suggestions on how to prevent location services from starting until explicitly needed. • Insights into any hidden triggers or indirect usages that might cause this behavior. Thank you for your time and assistance. Any help to resolve this issue would be greatly appreciated.
