Dynamic Location Tracking using CLServiceSession and CLBackgroundActivitySession
Hello, I'm currently implementing code to track routes and determine if users have arrived at their destination using CLServiceSession, CLBackgroundActivitySession, and CLLocationUpdate.liveUpdates. I want to obtain location data across all app states: foreground, background, and terminated. I have two questions: Background Location Indicator Issue: I'm using CLBackgroundActivitySession to get location updates in the background. Normally, the background location indicator (blue bar) doesn't appear at the top left of the screen for my app. However, when another app (e.g., LiveUpdatesSample) activates CLBackgroundActivitySession, my app's background location indicator suddenly becomes visible. Can you explain why this happens? or Can I Control showsBackgroundLocationIndicator in CLBackgroundActivitySession Session Management: Is there a way to terminate all currently active CLBackgroundActivitySessions? I understand that when CLBackgroundActivitySession is activated and the app is terminated and then relaunched, a new CLBackgroundActivitySession needs to be created. In this case, are the previously created and running CLBackgroundActivitySessions automatically released when the app is relaunched?

Lifecycle and Usage of CLServiceSession after the app is terminated
Hi, I am creating a Driving Behaviour Monitoring app in which I range beacons and I require location updates in foreground, background and in terminated state all the time. I am using CLServiceSession with "Always Authorisation" to get location events. I create CLServiceSession object in the foreground and start monitoring driving and then re-create it when the app is relaunched after termination. Doing this works fine. But sometimes when app is terminated and is not opened again, the app runs on its own even when the device is stationary ( I can see the app is using Location in the Control Centre) and after that Location updates are not received and I am not able to track the driving behaviour. I tried to add diagnostics to know the cause and found "Insufficiently In Use" and then "Service Session Required" in the diagnostics. It would be of great help if the proper usage of CLServiceSession is provided. Important Question: When does the CLServiceSession gets invalidated or destroyed that was created when the app was in foreground ? What happens to the CLServiceSession which was created in the foreground if the app is not opened for long duration, let's say a day or two?

Bluetooth permissions Query
Hi Team, when our customers turn on bluetooth connectivity whether Apple creates a profile of the user or their locations and if it is used for any other purpose. Could you please clarify this? we are getting the below message in the Bluetooth permissions popup below the map "Information from Bluetooth devices can be used to determine your location and create a profile of you." What is this profile? and what is the purpose of creating it while the user uses Bluetooth in ios app.

Do I need to maintain CLServiceSession when app relaunches from terminated state due to CLMonitor events?
I'm currently testing the CLMonitor API and have a question about CLServiceSession management. When my app is relaunched from a terminated state in the background due to CLMonitor events, do I still need to create and maintain a CLServiceSession instance? I'm wondering if CLServiceSession is necessary even when I don't need to continuously receive GPS updates through liveUpdates. Since CLMonitor can trigger app launches for region monitoring events without requiring constant location updates, I'm unclear about whether the CLServiceSession is still required in this scenario. Any clarification on the proper implementation would be greatly appreciated. Thanks!

Country from MKReverseGeocoding
As GeoCoder is now deprecated I am struggling to get the country only information from the new MKReverseGeocoding. Maybe someone can guide me or give me direction? Or is this just not possible anymore? let request = MKReverseGeocodingRequest(location: self.lastLocation ?? fallbackLocation) request?.getMapItems { items, error in guard let items = items else { return } self.cityName = items.first?.addressRepresentations?.cityWithContext ?? "" self.countryName = items.first?.addressRepresentations?.regionName ?? "" } I couldn't find anything here, sure you can get the full Address but I need single values to store so the user can search for (example City, Country) In case the structure is always the same, let us say the country is always third part, sure I could split the string but it is not a reliable way to do this, at least for me. Any help would be much appreciated.

SwiftUI issue with onTap using Map using IOS 26
I have a sample that stop working on IOS 26, using the latest XCode and IOS sdk, the onTapGesture event is no longer happening. Maybe this is no longer the way to drop pins on the map. Also not working on the iPhone 17 sim or iPhone 16 max pro device upgrading to IOS 26 Thanks, any help Sample: import SwiftUI import MapKit import CoreLocation import Foundation struct Pin: Identifiable { let id = UUID() let coordinate: CLLocationCoordinate2D } struct ContentTestPinDropView: View { @State private var pins: [Pin] = [] var body: some View { MapReader { reader in Map(selection: .constant(nil)) { ForEach(pins) { pin in Marker("Pin", coordinate: pin.coordinate) } } .onTapGesture { screenPoint in if let coordinate = reader.convert(screenPoint, from: .local) { pins.append(Pin(coordinate: coordinate)) } } } } }

External GPS receiver
Hello, We are a software and hardware development company for the forestry and environmental sectors. We have been based in Quebec (Canada) for over 30 years now. Our Canadian market covers Quebec, Ontario, and the Maritime provinces in the east. We are currently expanding across Canada and into the northern United States. We are on Android platforms with several map and data entry applications. To ensure the success of our expansion, we aim to become part of the Apple family, which is why we are contacting you today. We have developed our own GNSS receiver to increase the location accuracy of our users. It uses Bluetooth BLE to communicate with mobile devices and a high-precision GPS that transmits its position using the NMEA protocol. We would like this device to be compatible with an iPhone/iPad. We have developed a mock location application in MAUI (multi-platform). Based on our interpretation of your documentation, we understand that the concept of mock location does not exist at Apple. How can we ensure that our Bluetooth GNSS device is compatible with your iPhone/iPad devices and that they can use the position of the Bluetooth device rather than the internal GPS of your devices? We are a reseller for Juniper Systems, and we know that they have an app on the App Store that has the same features as our product. https://junipersys.com/index.php/support/article/14709 We look forward to your follow-up and recommendations.

Maps: opening hours API / Property
I’m currently developing an iOS app that relies heavily on location details. I'm using MapKit and MKMapItem as my primary data source, which works perfectly for standard metadata. However, I’ve hit a roadblock: I want to display opening hours inline within my location details, but it seems Apple doesn't expose a public API or property for this in MKMapItem (even though the data is clearly visible in the native Apple Maps app). Since I'm building this as an indie developer/startup, the Google Places API is unfortunately too expensive for my current budget. ⁠Is there any legitimate, native way to get opening hours from Apple that I might have missed? ⁠If not, what are your best practices or recommended indie-friendly alternatives (e.g., Yelp Fusion API, OpenStreetMap, Foursquare)? Any tips on how to handle this elegantly and cost-efficiently would be highly appreciated! Thanks in advance.

Request of CarPlay Navigation Entitlement when having the Driving Task one
I have the CarPlay Entitlement "Driving Task" and two of my apps use it. Now, in both apps, I have implemented Navigation. I requested the Navigation CarPlay Entitlement when the feature was mature and builds were available in Test Flight, since I wanted to release the new versions of the apps with navigation available both on the iPhone and in CarPlay. I got no answer to my request, so I decided to release the apps with only navigation in the iPhone and the Driving Task functionality in CarPlay, thinking that maybe being live with navigation in the App Store was a requirement. I have asked permission again, and so far, the request is being ignored again. What are the requirements to get the Navigation CarPlay Entitlement? If the app is approved for navigation, is there something else the app must do to get the entitlement? Requirements for CarPlay Entitlements seem quite obscure, are they listed anywhere? Is there a technical problem to move from an existing CarPlay Entitlement to another? Can that be the reason the entitlement has not been granted? Some of my competitors have the CarPlay Navigation entitlement. My use case is the same (in a better app in my opinion, of course). But I am only getting bad reviews because "the app does not include the map in CarPlay" after the big investment in implementing navigation in the apps. Any help or insight would be appreciated.

Are rate limits for calculate, calculateETA, and reverse geocoding shared across an app?
Hi, I'm using MapKit's MKDirections.calculate, calculateETA, and reverse geocoding (via CLGeocoder.reverseGeocodeLocation) in my iOS app. I understand that there are undocumented rate limits for these services to prevent abuse, but I couldn't find official details. I would like to know: Are the rate limits applied per device, per app installation, or are they shared across all users of the same app bundle ID? Is there any guidance on how to design these features to avoid hitting rate limits in a production environment? What is the best practice if a user repeatedly triggers routing or reverse geocoding (e.g., typing or moving the map)? Any clarification or official documentation would be greatly appreciated. Thank you!

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!

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?
