Does Showing User's Current Location on the Map Require 'NSLocationWhenInUseUsageDescription'?
I have a desktop application that shows some real estate properties chosen by the user. The application shows those GPP locations on the map. The SwiftUI code is something like the following. import SwiftUI import MapKit struct ContentView: View { var body: some View ZStack { mapView } } private var mapView: some View { Map(position: $propertyViewModel.mapPosition) { ForEach(propertyViewModel.properties) { property in Annotation("", coordinate: CLLocationCoordinate2D(latitude: property.lat, longitude: property.lon)) { Button { } label: { VStack { Image(systemName: "house.circle.fill") .resizable() .scaledToFit() .frame(width: 48) .foregroundStyle(colorScheme == .light ? .white : .black) ... } } .buttonStyle(.borderless) } } UserAnnotation() } .mapControls { MapUserLocationButton() } .mapControlVisibility(.visible) .onAppear { CLLocationManager().requestWhenInUseAuthorization() } } } The application only wants to use the CLLocationManager class so that it can show those locations on the map relative to your current GPS position. And I'm hit with two review rejections. Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage Issue Description One or more purpose strings in the app do not sufficiently explain the use of protected resources. Purpose strings must clearly and completely describe the app's use of data and, in most cases, provide an example of how the data will be used. Guideline 5.1.5 - Legal - Privacy - Location Services The app uses location data for features that are not relevant to a user's location. Specifically, the app is not functional when Location Services are disabled. So I wonder if the application is even required to have 'NSLocationWhenInUseUsageDescription' and/or 'NSLocationUsageDescription'? just in order to show user's current location so that they can see property locations relative to it? The exact location privacy statement is the following. The application needs your permission in accessing your current location so that it will appear on the map

Does anyone know how to achieve this custom MKAnnotation?
I’ve notice that in Maps, some pins contain images and do not have the little triangle at the bottom of it, yet they still animate the same when clicked. How could this be achieved? I believe the name of this annotation is MKMapFeatureAnnotation. I've tried this and it did not give the same result. I'm able to create a custom MKMarkerAnnotationView but it does not animate the same (balloon animation like the MKMapFeatureAnnotation). I was looking forward to create a custom MKMapFeatureAnnotation similar in design which would animate the same. Unfortunately, I cannot create a custom MKMapFeatureAnnotation because everything is privated

NSLocationDefaultAccuracyReduced not taking effect after app update (YES -> NO) for first-time location authorization
Hello Apple Developer Technical Support / Core Location Team, I’m requesting clarification on the effective timing of the Info.plist key NSLocationDefaultAccuracyReduced. We shipped Version A with NSLocationDefaultAccuracyReduced = YES (reduced accuracy by default). In Version B we changed it to NO. After updating to Version B, on devices/users that have not previously granted location authorization for our app, the first authorization flow still behaves as if reduced accuracy is the default (i.e., the same behavior as Version A). Could you please confirm: When iOS evaluates/caches NSLocationDefaultAccuracyReduced (install time, app launch, or at first authorization prompt)? After an update changes this key from YES to NO, should the new value apply to users who have never authorized location for the app? Environment: Iphone 16 (IOS 26.0) I can provide a sysdiagnose and additional logs if needed. Thank you, Jack

why mapkit js does not have LookAroundSceneRequest
I want to update coordinate of the lookaround instance object. But mapkit.js does not have LookAroundSceneRequest class, how am I going to do. In swift, there is MKLookAroundSceneRequest class, you can specify a new coordinate with this class, to get a new LookAroundScene object, then attach new LookAroundScene to the existing lookAround object, But how am I going to do the same with mapkit.js ?? it missing LookAroundSceneRequest class in js

ITMS-90118: Invalid routing app setting:
Hi everyone, I’m running into an App Store Connect issue that seems to be a misclassification, and I’m hoping someone (or Apple staff) can help clarify or advise. App: Quick Quote Calculator Platform: iOS (built with Expo) App type: Business No navigation, routing, maps, or turn-by-turn directions When submitting a new build, App Store Connect returns: ITMS-90118: Invalid routing app setting To upload a routing app coverage file, you must define the app binary as a routing app. However: There is no “Routing & Navigation” section in App Information There is no “Routing App Coverage File” section under App Store No routing metadata or coverage file has ever been uploaded The app does not provide routing or navigation functionality It appears the binary itself is being classified as a routing app, but there is no UI in App Store Connect to view or remove this classification. What I’ve tried Verified app metadata and screenshots Confirmed no routing/navigation APIs are used Reviewed Info.plist permissions (no routing language) Uploaded a new build with incremented build number Has anyone run into a case where a routing flag is applied at the binary level and the Routing App options are not exposed in App Store Connect? Is the only resolution to have Apple manually remove the routing classification via App Review / Developer Support? Any insight from Apple staff or devs who’ve resolved this would be hugely appreciated. Thanks in advance! Yes — the app is strictly a business quote calculator for trades. It calculates distance (Miles via addresses) but does not display maps, routes, directions, or navigation of any kind.

LocationButton (SwiftUI) broken or changed in iOS 26?
I just spend the morning debugging LocationButton and the associated CLLocationManagerDelegate only to realise that it works perfectly in iOS 18.5 but no longer works for me in iOS 26.0, 26.2 or 26.2.1 (the latter on-device). It does work when I run my app on macOS 26.2 (Designed for iPad). Is there a change in behaviour or requirements on iOS I am missing? On iOS 18.5 I observe that the authorisation status changes from .notDetermined to .authorizedWhenInUse after the LocationButton has been tapped and my delegate is able to obtain the location through locationManager(_ , didUpdateLocations:). On iOS 26.x the authorisation status remains .notDetermined and my delegate receives locationManager(_:didFailWithError:) with error code .denied. Setting NSLocationWhenInUseUsageDescription in my Info.plistdid not help. Just in case ;) FB21798098 (SwiftUI LocationButton fails to acquire authorization on iOS 26)

Errors with PerfPowerTelemetryClientRegistrationService and PPSClientDonation when running iOS application in Xcode
I've suddenly started seeing hundreds of the same block of four error messages (see attached image) when running my app on my iOS device through Xcode. I've tried Cleaning the Build folder, but I keep seeing these messages in the console but can't find anything about them. Phone is running iOS 26.1. Xcode is at 16.4. Mac is on Sequoia 15.5. The app is primarily a MapKit SwiftUI based application.

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!

iOS suspends app after BLE discovery even though I start Always-authorized location udpates (Target deployment: 16.3+)
I’m hitting a specific edge case with background execution that I can’t figure out. I'm using Flutter for the UI, but all the logic handles are in Swift using CoreBluetooth and CoreLocation. I need the app to wake up from a suspended state when it detects my specific BLE peripheral (OBD sensor), connect to it, and immediately start continuous location tracking for the duration of the drive. If I start this process while the app is in the foreground, or very shortly after going to BG, it works perfectly. The app stays alive for the whole trip. The issue only happens when the sequence starts from the background: The app is suspended. scanForPeripherals wakes the app when the sensor is found. In didDiscover, I immediately call locationManager.startUpdatingLocation(). locationd actually delivers updates successfully. However, 5-15 minutes later, iOS suspends the app again. Crucially, I never see the blue "Location In Use" pill on the status bar, even though I have showsBackgroundLocationIndicator = true set. Also, distance filter is set to None. Logs for reference (around suspending) locationd: {"msg":"Sending location to client","Client":"[appName]:","desiredAccuracy":"-1.000000"} runningboardd: Invalidating assertion ... from originator \\\[osservice<com.apple.bluetoothd>:...\\\] runningboardd: Removed last relative-start-date-defining assertion for process app<[appName]...> runningboardd: Calculated state ... running-suspended runningboardd: Suspending task locationd: Client [appName]: disconnected bluetoothd: State of application "[appName]" is now "suspended" Questions Why does invalidating the Bluetooth assertion cause an immediate suspend even though I called startUpdatingLocation() and am receiving updates? Does the missing blue location pill imply that the OS never fully "accepted" the location session? Is there a specific "handshake" required to transition from a BLE wake-up to a long-running location session? I'm wondering if I need to use a background task identifier to bridge the gap between the BLE wake and the location manager taking over. More context: Digging deeper in the comments, I just noticed the following patterns when the application is not suspended vs when it is recently suspended and got awaken by a BLE event. Not suspended: 303948:Jan 23 20:59:35.640118 locationd[6491] <Debug>: {"msg":"Client is setting ContinuousBackgroundLocationRequested", "Client":"[appName]:", "ContinuousBackgroundLocationRequested":1} 303949:Jan 23 20:59:35.640155 locationd[6491] <Debug>: {"msg":"Allowing process assertion due to foreground-ish status", "ClientKeyPath":"[appName]:"} Recently suspended and awaken by BLE: 564296:Jan 23 21:00:23.179125 locationd[6491] <Debug>: {"msg":"Client is setting ContinuousBackgroundLocationRequested", "Client":"[appName]:", "ContinuousBackgroundLocationRequested":1} 564298:Jan 23 21:00:23.179195 locationd[6491] <Notice>: {"msg":"#Warning Denying process assertion", "ClientKeyPath":"[appName]:"} The assertion fails for the second case and that's why the app could not persist. Most importantly, following the logs in the second case, I see the following: locationd[6491] <Notice>: {"msg":"computing freshAuthorizationContext", "Client":"[appName]:", "ClientDictionary":"{\n AlwaysServiceSession = 0;\n I suspect that the flag AlwaysServiceSession being 0 has to do with process assertion being denied for location.

Z-Index for MarkerAnnotation
Hey there, is there a way to set the z-index for MarkerAnnotations in MapkitJS? I'm loading up to 200 markers dynamically as the map moves or the user zooms and I want a few specific markers to always be at the top (the best search results). The only way I found is to always remove all markers and then add them again in the right order, but that's visually so annoying to see them disappear and animate in with every tiny movement. I thought about using a default Annotation and setting the z-index myself and trying to rebuild the balloon, including the animation when it's clicked, but the big downside is probably the performance because I won't be able to use shadow DOM elements and have 200 real DOM elements instead. Is there a solution to this right now or is it planned to add a feature like that to Mapkit JS? It's a real blocker for me right now because all the bad content always gets rendered on top when a user zooms in, because I obviously want to show the best content first when the user isn't zoomed in yet. Thank you so much in advance. I really appreciate it. Manuel

The Example App for Monitoring Location Changes Doesn't Work
Downloaded example app from here Xcode version: Version 26.1.1 (17B100) Simulator iOS Version: 26.1 & 18.5 Set custom location in the simulator to the center of the condition being monitored in the example. The only log entry was "Setup Monitor". Tried a custom gpx starting at the same point and moving 500m away. Same logs. Didn't change any of the source code, granted always permissions, allowed notifications, tapped "AddCircularGeographicCondition". Let me know if there is something I am missing or more information I can provide.

Clarifying the intended scope of DL-TDoA ranging in Nearby Interaction
Does DL-TDoA ranging in the Nearby Interaction framework support building a traditional RTLS-style TDoA localization system, where a device’s absolute position is computed from time-difference measurements across multiple deployed anchors, or is DL-TDoA strictly limited to system-managed, relative ranging and direction estimation (distance/direction) between nearby devices? If DL-TDoA ranging in Nearby Interaction is not intended to support traditional RTLS-style TDoA localization, is there any public documentation or reference material that describes the intended DL-TDoA architecture, such as the expected system setup, device roles, and deployment constraints (for example, how ranging is expected to be performed between an iPhone and nearby accessories), beyond the high-level API documentation? Regards.

iPad Compass Calibration Issues: Impact of Magnetic Cover
We have developed an iPad application using the ARCL (AR + CoreLocation) library to render Point of Interest (POI) annotations in both an AR view and a standard MapView. The application performs as expected on standard devices. However, we have some iPad covered with strong magnet. This creates significant magnetic interference, resulting in a 90° to 180° heading offset, rendering the AR POI placement and MapView orientation unusable. Technical Challenges & Constraints: Hardware Lock: The magnetic cover is a mandatory business requirement and cannot be removed during field use. Sensor Failure: The internal magnetometer cannot provide an accurate North reference due to the proximity of the cover’s magnets. While CoreLocation and CoreMotion use sensor fusion, the magnetometer remains the primary source for absolute heading. Alternative Orientation Tracking: Is there a documented method to bypass the magnetometer and derive device orientation using only the Gyroscope and Accelerometer (e.g., relative tracking) while still maintaining alignment with geographic coordinates in CoreLocation? Programmatic Offsets: Are there known APIs or mathematical workarounds to programmatically "nullify" or offset a constant magnetic bias once the device is inside the cover? so we can use that offset for ARView and in Mapview as well.

Question about MFi token access
Hi all, Our company is applying for the Find My certification for our smartwearable product. Now we submitted the product plan and it's approved. The lab asked us to get the token but we searched on internet and the documents about it are limited. The CSR has approved and we already had .pem and .key file. I wonder what should we do next. Any helps are appreciated

Reverse geocoding rate limit of MKReverseGeocodingRequest compared to CLGeocoder
The documentation for CLGeocoder states Geocoding requests are rate-limited for each app, so making too many requests in a short period of time may cause some of the requests to fail. (When the maximum rate is exceeded, the geocoder returns an error object with the CLError.Code.network error to the associated completion handler.) And it provides helpful guidance on how and when to submit geocoding requests. The documentation for MKReverseGeocodingRequest does not mention requests are rate-limited. Does this mean it is not rate-limited? If it is rate-limited, is it similar to CLGeocoder, what is its behavior? It is important to understand behavior of the API in order to understand impact on my app’s use case and how users will be affected should I change the implementation. Thanks!

Altitude for MKAnnotation
In MapKit, the MKAnnotation takes a CLLocationCoordinate2D. However, in 3D/Flyover mode, the user marker has a height position on the map. We are currently plotting points which have altitude, speed, heading, etc, and I have a method for creating a CLLocation with this information. What I'm trying to figure out is if there's a way to pass that information along to the MapKit rendering engine / annotations / AnnotationViews to recognize and show when in 3D mode. Is there any support for that currently?

Apple Map App Crash, when witched to satellite view
hi, When changing the map to Satellite in Apple Maps and centering it on Ōmuta City, Fukuoka Prefecture, Japan (as shown in the image), the app crashes when swiping to the right. This issue also occurs in MapKit, and I confirmed it happens in Apple Maps as well. It seems that either the satellite map tiles are missing or an error is occurring. Our application is experiencing a crash, and this has become a serious issue. Since September 1, crashes have increased significantly. Initially, we suspected that the issue was due to our application’s implementation, but our investigation revealed that the problem lies with the map tiles being called through MapKit. Could you please investigate this issue and provide a fix?

Hey there, is there a way to set the z-index for MarkerAnnotations in MapkitJS? I'm loading up to 200 markers dynamically as the map moves or the user zooms and I want a few specific markers to always be at the top (the best search results). The only way I found is to always remove all markers and then add them again in the right order, but that's visually so annoying to see them disappear and animate in with every tiny movement. I thought about using a default Annotation and setting the z-index myself and trying to rebuild the balloon, including the animation when it's clicked, but the big downside is probably the performance because I won't be able to use shadow DOM elements and have 200 real DOM elements instead. Is there a solution to this right now or is it planned to add a feature like that to Mapkit JS? It's a real blocker for me right now because all the bad content always gets rendered on top when a user zooms in, because I obviously want to show the best content first when the user isn't zoomed in yet. Thank you so much in advance. I really appreciate it. Manuel

iOS 17: location permissions keeps changing on its own
I set the location permission to Always but it changes back to “when shared” after a few days. Is this a bug?

The Example App for Monitoring Location Changes Doesn't Work
Downloaded example app from here Xcode version: Version 26.1.1 (17B100) Simulator iOS Version: 26.1 & 18.5 Set custom location in the simulator to the center of the condition being monitored in the example. The only log entry was "Setup Monitor". Tried a custom gpx starting at the same point and moving 500m away. Same logs. Didn't change any of the source code, granted always permissions, allowed notifications, tapped "AddCircularGeographicCondition". Let me know if there is something I am missing or more information I can provide.

Why is MKTileOverlay not available on watchOS?
As title says. Surely rendering bitmaps is something the hardware could handle, right? Please enable MKTileOverlay for watchOS.

Clarifying the intended scope of DL-TDoA ranging in Nearby Interaction
Does DL-TDoA ranging in the Nearby Interaction framework support building a traditional RTLS-style TDoA localization system, where a device’s absolute position is computed from time-difference measurements across multiple deployed anchors, or is DL-TDoA strictly limited to system-managed, relative ranging and direction estimation (distance/direction) between nearby devices? If DL-TDoA ranging in Nearby Interaction is not intended to support traditional RTLS-style TDoA localization, is there any public documentation or reference material that describes the intended DL-TDoA architecture, such as the expected system setup, device roles, and deployment constraints (for example, how ranging is expected to be performed between an iPhone and nearby accessories), beyond the high-level API documentation? Regards.

iPad Compass Calibration Issues: Impact of Magnetic Cover
We have developed an iPad application using the ARCL (AR + CoreLocation) library to render Point of Interest (POI) annotations in both an AR view and a standard MapView. The application performs as expected on standard devices. However, we have some iPad covered with strong magnet. This creates significant magnetic interference, resulting in a 90° to 180° heading offset, rendering the AR POI placement and MapView orientation unusable. Technical Challenges & Constraints: Hardware Lock: The magnetic cover is a mandatory business requirement and cannot be removed during field use. Sensor Failure: The internal magnetometer cannot provide an accurate North reference due to the proximity of the cover’s magnets. While CoreLocation and CoreMotion use sensor fusion, the magnetometer remains the primary source for absolute heading. Alternative Orientation Tracking: Is there a documented method to bypass the magnetometer and derive device orientation using only the Gyroscope and Accelerometer (e.g., relative tracking) while still maintaining alignment with geographic coordinates in CoreLocation? Programmatic Offsets: Are there known APIs or mathematical workarounds to programmatically "nullify" or offset a constant magnetic bias once the device is inside the cover? so we can use that offset for ARView and in Mapview as well.

Question about MFi token access
Hi all, Our company is applying for the Find My certification for our smartwearable product. Now we submitted the product plan and it's approved. The lab asked us to get the token but we searched on internet and the documents about it are limited. The CSR has approved and we already had .pem and .key file. I wonder what should we do next. Any helps are appreciated

Reverse geocoding rate limit of MKReverseGeocodingRequest compared to CLGeocoder
The documentation for CLGeocoder states Geocoding requests are rate-limited for each app, so making too many requests in a short period of time may cause some of the requests to fail. (When the maximum rate is exceeded, the geocoder returns an error object with the CLError.Code.network error to the associated completion handler.) And it provides helpful guidance on how and when to submit geocoding requests. The documentation for MKReverseGeocodingRequest does not mention requests are rate-limited. Does this mean it is not rate-limited? If it is rate-limited, is it similar to CLGeocoder, what is its behavior? It is important to understand behavior of the API in order to understand impact on my app’s use case and how users will be affected should I change the implementation. Thanks!

Altitude for MKAnnotation
In MapKit, the MKAnnotation takes a CLLocationCoordinate2D. However, in 3D/Flyover mode, the user marker has a height position on the map. We are currently plotting points which have altitude, speed, heading, etc, and I have a method for creating a CLLocation with this information. What I'm trying to figure out is if there's a way to pass that information along to the MapKit rendering engine / annotations / AnnotationViews to recognize and show when in 3D mode. Is there any support for that currently?

Apple Map App Crash, when witched to satellite view
hi, When changing the map to Satellite in Apple Maps and centering it on Ōmuta City, Fukuoka Prefecture, Japan (as shown in the image), the app crashes when swiping to the right. This issue also occurs in MapKit, and I confirmed it happens in Apple Maps as well. It seems that either the satellite map tiles are missing or an error is occurring. Our application is experiencing a crash, and this has become a serious issue. Since September 1, crashes have increased significantly. Initially, we suspected that the issue was due to our application’s implementation, but our investigation revealed that the problem lies with the map tiles being called through MapKit. Could you please investigate this issue and provide a fix?
