Summary While parallel testing Core Location on the new iOS 26.1 beta (23B5044i), I observed what I believe to be a regression of the issue described here: https://developer.apple.com/forums/thread/779192 Specifically, user positioning underground subway stations is noticeably inaccurate on the beta, whereas the same scenarios remain accurate on the unupgraded device below. I work with the MTA (New York City) and work with the OP of that thread. Happy to provide additional testing or details if helpful. Please let me know what else you need. Test Info Riding NYCT from Wall St to 34th St Penn Station on the 2 train carrying two iphones Recording: https://limewire.com/d/dpTWi#pDC3GRYIdE Expected: Consistent underground positioning comparable to prior releases.

I am developing a navigation application. My goal is for this navigation app to also work in the background and provide the user with real-time directional updates. When apps request access to location services, users see a TCC (Transparency, Consent, and Control) prompt. This prompt allows the user to choose under what conditions the app can access location services (for example: “While Using the App”, “Always”, etc.). If the user selects the “While Using the App” option, can the navigation app still access location in the background and provide directional information to the user? Is something like this technically possible? Does Apple allow this behavior for navigation apps or similar use cases?

Hello, I'm working on an application that requires the use of significant location changes and visits, in addition to region monitoring and standard continuous location delivery (foreground and background). iOS 17 and iOS 18 introduced changes to how we can monitor distinct regions of interest (with CLMonitor) as well as receive location updates (with CLLocationUpdate). But I couldn't find any information regarding how to work with Significant location changes. Do we still need to create a location manager and call startMonitoringSignificantLocationChanges()? Where are the updates received in this case, in the locationManager(_:didUpdateLocations:) or in the liveUpdates async sequence? Visits. Same question here, for visit monitoring to work, do we still have to create a location manager then call startMonitoringVisits()? Where are the visits being notified? Still in locationManager(_:didVisit:) or in the liveUpdates asynchronous sequence? I just want to be sure I understand correctly how to use the updates, and if some features of Core Location still need to use a location manager and the delegate to receive the events. Maybe additional CLCondition will be added to cover both of these technologies as it seems highly related to monitoring conditions (significant location change, and visit). Thank you, Axel

Dear Apple Team, I am reaching out regarding the need for more sophisticated location verification APIs beyond basic IP lookup capabilities. As online fraud continues to evolve, IP-based geolocation has proven insufficient for many business use cases requiring accurate location verification. Would it be possible to discuss this proposal with your API development team? I believe this would be valuable for the entire iOS and macOS developer ecosystem while maintaining Apple's commitment to user privacy.

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!

We are developing a mileage tracking application that depends on continuous background location updates on iOS. Our app has the required background modes enabled: <key>UIBackgroundModes</key> <array> <string>remote-notification</string> <string>processing</string> <string>fetch</string> <string>location</string> </array> We are observing inconsistent behavior with background location tracking in app terminated state. In some cases, after a period of time, location updates stop completely. Sometimes iOS successfully relaunches the app when movement is detected and location updates resume correctly. However, in other cases, the app is not relaunched by the system, and we stop receiving location updates entirely. We reviewed Apple’s documentation on handling background location updates: https://developer.apple.com/documentation/corelocation/handling-location-updates-in-the-background Based on our observations, we would appreciate clarification on the following points: Is this considered expected iOS behavior or a system limitation? Under what conditions does iOS decide not to relaunch a terminated app for location events? Are there recommended best practices to improve the reliability of background location relaunch behavior? Is there any logging, diagnostics, or debugging mechanism available to determine why the app was not relaunched? Apple’s documentation mentions that location updates may be queued while the app is terminated and later delivered after relaunch. However, in some scenarios we do not receive those queued updates after the app restarts. Under what conditions can queued location updates be discarded or not delivered? Additional notes: We are using standard Core Location background updates. “Always” location permission is granted. Background App Refresh is enabled. The issue is observed intermittently across multiple iOS devices.

Hello, I’m planning to use MapKit JS for a production web/mobile application and I’m trying to better understand the quota limits and pricing model. From the documentation, I understand that MapKit JS provides a free daily limit of: 250,000 map views 25,000 service calls per Apple Developer Program membership. However, I’m not clear about what exactly happens if these limits are exceeded. My questions: If my application exceeds 250,000 map views or 25,000 service calls in a day, what happens? Will the API simply start returning errors (for example HTTP 429), or will Apple automatically charge for additional usage? Is there an official pricing model for usage above the free quota, or do we need to contact Apple to request higher limits? Are these limits strict daily hard limits that should never be exceeded in production? I’m trying to design the architecture of my application and would like to understand whether we must strictly stay below these limits or whether scaling beyond them is possible. Thank you.

I am building a Swift Playgrounds App project on iPad running iPadOS 26.0.1 using the latest version of Swift Playgrounds. I need to access Core Location for a plant location logging app. What I have done: • Created an App project (not a Playground) in Swift Playgrounds • Enabled ‘Core Location When in Use’ in the app capabilities (accessed by tapping the app name) • Implemented a CLLocationManager with CLLocationManagerDelegate • Called manager.requestWhenInUseAuthorization() from .onAppear in a SwiftUI view • Called manager.startUpdatingLocation() immediately after The problem: The location permission prompt never appears when the app runs. The app does not appear in Settings → Privacy & Security → Location Services at all. There are no error messages or crashes — the app simply never requests location access. What I have ruled out: • The capability IS enabled in Swift Playgrounds app settings • The app runs without errors otherwise • This is an App project, not a classic Playground, so it should support capabilities Questions: 1. Is CLLocationManager with requestWhenInUseAuthorization() supported in Swift Playgrounds App projects on iPadOS 26? 2. Has the location authorization API changed in iPadOS 26 in a way that affects Swift Playgrounds? 3. Is there a working code example for Core Location in a Swift Playgrounds App project on iPadOS 26? Any guidance would be greatly appreciated.

We want to implement continuous GPS tracking in a React Native iOS app for security purposes. We need the tracing in the following case scenarios: App is Terminated App is minimised (Not killed) App is open and device is put to sleep mode #Locked App is in minimised and device is put to sleep mode #Locked (sleep mode) Currently it works in following 2 scenarios: Working when the app open in foreground Works when the app is killed (Traces in background) We would like to understand: Is continuous background location tracking during device idle allowed in iOS ? If allowed, what is the recommended approach to ensure reliable tracking? Are there any specific configurations, permissions, or limitations (battery optimization, system restrictions) we should be aware of? We are using React-Native by transistersoft with background location updates enabled and required permissions configured. This use case is specifically for user safety and security tracking. Any guidance on best practices and platform limitations would be helpful.

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.

Issue from App Review: My app shows a custom explanation screen before triggering the system location permission dialog. This screen explains why location access is needed. It includes: A “Continue” button → triggers the system permission dialog A “Not Now” button → dismisses the explanation and delays the permission request Apple states that: “The user should always proceed to the permission request after the message.” They are asking me to remove the exit button from the pre-permission message. My Questions Is it now against policy to include a “Not Now” option in a pre-permission explainer screen? Are we required to immediately show the system permission dialog after any pre-permission explanation? What is the recommended UX pattern if the feature depends on location but I don’t want to force the permission immediately at launch? Would it be compliant to: Remove the “Not Now” button, OR Remove the custom pre-prompt entirely and rely only on the system dialog? The feature in question requires location to function properly, but I want to implement it in a user-friendly way that respects user choice and avoids unnecessary denial rates. If anyone has recently resolved a similar 5.1.1(iv) issue, I’d really appreciate hearing how you handled it. Thank you in advance for your help!

Hello, thanks for your effort! I found that when showsUserLocation is set to true (by default), the pulsing blue dot user location annotation is shown, which is cool and beautiful. However, it will automatically and periodically attempt to call the Apple Server API GET https://api.apple-mapkit.com/v1/reverseGeocode within userLocationDidChange() and updateUserLocationAnnotation() to display, I assume, the user's current address when single-tapping on the blue dot. It will significantly use the MapKit service calls quota since the user location is automatically updated. It almost runs out of quota even though the map initialization is plenty enough. Is there any way to disable the bubble behavior but preserve the user location blue dot, which is lovely and better than drawing my own user location dot? It seems I can only turn off all user location features. Many thanks!

I have a desktop application developed in SwiftUI that shows property locations on the map. That's NOT the main feature. IF you give the application permission to access your location, the blue dot will appear on the map. If you don't, the blue user dot won't appear. That's the only difference with location services. In other words, the application has no use of user's current position beyond showing it on the map. Since it's just the matter of showing or not showing the blue dot on the map, the application doesn't really need to use the location service. Anyway, the reviewer is talking about something else by rejecting the application in two aspects. Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage Guideline 5.1.5 - Legal - Privacy - Location Services As I said earlier, the application only wants to show the blue dot on the map so that you can see your property locations relative to your current location. In code, it's something like the following. Map(position: $propertyViewModel.mapPosition) { ForEach(propertyViewModel.properties) { property in Annotation("", coordinate: CLLocationCoordinate2D(latitude: property.lat, longitude: property.lon)) { ... } } UserAnnotation() } So I'm hit with two rejection reasons with this one line. UserAnnotation() And the reviewer is talking about something like the app is not functional when Location Services are disabled. To resolve this issue, please revise the app so that the app is fully functional without requiring the user to enable Location Services. Well, I can remove the UserAnnotation() line if I want to put this application through the review process. Nothing will become dysfunctional, though, if you decide to reject permission request. So would you remove it or would you play along with this reviewer if you were me? It's been three or four days since rejection. As you can imagine, the reviewer doesn't bother to answer as to What are the exact coordinates that the application has allegedly collected What won't work as a result of location permission request refusal. This isn't the first time I get my app rejected. I've probably had 150 to 200 of them rejected in the past 15 years. And just because a reviewer rejects your app for a bizarre reason, would you give in? Remove this feature and that feature because the reviewer is incompetent such that he or she makes his or her decision based on imagination? What do you think?

Is there an API to programmatically create a guide for iOS 14 Maps? I know third-parties are curating Guides. I'd like to programmatically create a guide.

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

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?

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!

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?

Hello, I’d like to ask about best practices for handling interactive snippet intents when working with the user’s location. My use case is: 1. Get the user’s location 2. Fetch nearby data 3. Display it My current flow is: try to show the snippet view in "loading" state while waiting for Core Location Manager, then fetch data and reload() the view. BUT I’m running into an issue where I sometimes receive Core Location error 1 (not authorized), even though the main app has “While In Use” authorization. It seems that in some cases, especially when the app has been force-closed, App Intents are unable to start location updates, even though I’m using supportedModes = .foreground(.dynamic). Any guidance would be appreciated. Cheers, Ondrej
