Clarification needed regarding requirements for geofencing
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?

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!

Background location stops with (kCLErrorDomain error 1.) but permission was granted
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?

Specify location for SwiftUI Previews
I'm working on an app that uses MapKit and CoreLocation. Is there a way to specify what location is simulated for a Preview, or create a preview that behaves as if the user denied location permissions, so that I can easily test my app's behavior in different scenarios? I know that you can simulate different locations in the Simulator, but haven't been able to get the previews within Xcode to have a location other than the center of Apple Park.

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!

Clustering on MapKit for SwiftUI iOS17+
Hi What would be the best way to achieve clustering on MapKit within SwiftUI? We're building a decentralized commerce auction platform that is currently live in Switzerland with 3'500 live auctions that can be discovered on a map. We're now running into the issue that the map gets cluttered, when zooming out and haven't been able to find a way to cluster We moved back to UIKit, where clustering works, but UIKit has other drawdowns. So ideally there is a way to handle it within SwiftUI without having to wrap UIKit or move back entirely to UIKit. Thanks for any help or suggestions!

MKReverseGeocodingRequest and CNPostalAddress from MKMapItem
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!

Incorrect position rendering of WGS84 coordinate in MKMapView: Discrepancy between Apple Maps (Hong Kong) and Amap (Mainland China)
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?

CLLocation.sourceInformation.isSimulatedBySoftware not detecting third-party location spoofing tools
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

iOS 26: Maps share sheet no longer provides com.apple.mapkit.map-item and only shares short maps.apple/p/... URLs (how to get coordinates?)
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?

Testing Significant Location Change
We are currently developing a research-based iOS application that relies heavily on background capabilities, specifically Significant Location Change. We are using CLLocationManager.startMonitoringSignificantLocationChanges(). During development, when using Debug → Simulate Location in Xcode, we receive a location update only once. Subsequent simulated location changes do not trigger additional callbacks, which makes testing and development quite cumbersome. Are there any tools, commands, or workflows (e.g., via Xcode, Instruments, or system-level simulation) to reliably simulate multiple significant location change callbacks for testing purposes? If there aren't such tools, how do I test this behaviour reliably, robustly and rigidly?

Significant change or restart app without location UIBackgroundModes key
Situation: We have an app that only uses location UIBackgroundModes key to restart our app on significant change events as we need it to connect with a BLE device (mounted in the car) when someone starts driving. We cannot use geofence as the car might be used by multiple people so position changes and we don't want to store locations and sent them to multiple users via our servers. So currently we use significant change and just ignore all other location data. During app review we got the following feedback: If the app does not require persistent real-time location updates, please remove the "location" setting from the UIBackgroundModes key. You may wish to use the significant-change location service or the region monitoring location service if persistent real-time location updates are not required for the app features. Question: How to use the significant-change location service without the "location" setting from the UIBackgroundModes key or is there any other way to start the app / connect with the BLE device when it is fully terminated/swiped away? Because the docs state that AuthorizationStatusAuthorizedAlways is required and without the UIBackgroundModes key location that wouldn't be triggered when app is in the background/swiped away. Reference: https://developer.apple.com/library/archive/documentation/UserExperience/Conceptual/LocationAwarenessPG/CoreLocation/CoreLocation.html#//apple_ref/doc/uid/TP40009497-CH2-SW8

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.

Background Modes - App Identifiers
Hey All, Seem to be in a loop and unable to proceed. New app specific for iOS being built on xCode. Project is configured only to deploy and use iOS, not macOS or anything else. Trying to create a new App iD always see it default to all platforms which means "Background Modes" is not visible or available. Automatic signing etc in xcode can't seem to get around this and just continues to flag I'm missing the entitlement for locations.background. Not sure what I am missing as I cannot manually configure the ID for iOS only and xcode is also generating new ID's with the same platform structure and constraints. Any thoughts or insights here please?

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.

kCLErrorLocationUnknown becoming a big issue
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.

MKReverseGeocodingRequest and CNPostalAddress from MKMapItem
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!

Incorrect position rendering of WGS84 coordinate in MKMapView: Discrepancy between Apple Maps (Hong Kong) and Amap (Mainland China)
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?

CLLocation.sourceInformation.isSimulatedBySoftware not detecting third-party location spoofing tools
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

iOS 26: Maps share sheet no longer provides com.apple.mapkit.map-item and only shares short maps.apple/p/... URLs (how to get coordinates?)
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?

Testing Significant Location Change
We are currently developing a research-based iOS application that relies heavily on background capabilities, specifically Significant Location Change. We are using CLLocationManager.startMonitoringSignificantLocationChanges(). During development, when using Debug → Simulate Location in Xcode, we receive a location update only once. Subsequent simulated location changes do not trigger additional callbacks, which makes testing and development quite cumbersome. Are there any tools, commands, or workflows (e.g., via Xcode, Instruments, or system-level simulation) to reliably simulate multiple significant location change callbacks for testing purposes? If there aren't such tools, how do I test this behaviour reliably, robustly and rigidly?

Significant change or restart app without location UIBackgroundModes key
Situation: We have an app that only uses location UIBackgroundModes key to restart our app on significant change events as we need it to connect with a BLE device (mounted in the car) when someone starts driving. We cannot use geofence as the car might be used by multiple people so position changes and we don't want to store locations and sent them to multiple users via our servers. So currently we use significant change and just ignore all other location data. During app review we got the following feedback: If the app does not require persistent real-time location updates, please remove the "location" setting from the UIBackgroundModes key. You may wish to use the significant-change location service or the region monitoring location service if persistent real-time location updates are not required for the app features. Question: How to use the significant-change location service without the "location" setting from the UIBackgroundModes key or is there any other way to start the app / connect with the BLE device when it is fully terminated/swiped away? Because the docs state that AuthorizationStatusAuthorizedAlways is required and without the UIBackgroundModes key location that wouldn't be triggered when app is in the background/swiped away. Reference: https://developer.apple.com/library/archive/documentation/UserExperience/Conceptual/LocationAwarenessPG/CoreLocation/CoreLocation.html#//apple_ref/doc/uid/TP40009497-CH2-SW8

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 }

Background Modes - App Identifiers
Hey All, Seem to be in a loop and unable to proceed. New app specific for iOS being built on xCode. Project is configured only to deploy and use iOS, not macOS or anything else. Trying to create a new App iD always see it default to all platforms which means "Background Modes" is not visible or available. Automatic signing etc in xcode can't seem to get around this and just continues to flag I'm missing the entitlement for locations.background. Not sure what I am missing as I cannot manually configure the ID for iOS only and xcode is also generating new ID's with the same platform structure and constraints. Any thoughts or insights here please?

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() }

kCLErrorLocationUnknown becoming a big issue
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.
