I am using CLServiceSession(authorization: .always) to start a service session for tracking Zone entry and exit in the background in my app. It has been working fine on iOS 18 until recently when we added some BGProcessingTasks.
The task runs when the user is not moving and the device is on charge, this task runs fro a bit in the background, however we are seeing that even though we are reinitializing then session upon app launch.
We have even tried to just explicitly reinitialize a session within the background task callback, but the zone tracking still continues to fail. Significant location changes are unaffected.
Timeline of events:
User Opens App,
CLServiceSession(authorization: .always) is called (assume permissions have already been granted.)
App is backgrounded
User moves outside zone and app captures the data correctly (this can happen any amount of times)
User plugs in Phone
BGProcessingTask callback is run, it may or may not be terminated early. The service session is recreated as the first action in the callback. (we have also tried putting it in the main init() function for the app, same outcome)
User moves outside zone later and app does NOT capture the data.
User is sad :(
The session seems to be reinitialized correctly when the app is launched due to CoreLocation updates.
Is this expected behaviour or a bug? Is there a good way to debug what is happening with the sessions?
Unfortunately, the WWDC sessions on this have not enlightened us about the cause of this behaviour.

Hello, dear engineer:
The UWB Accessory used by my APP has inconsistent code callbacks on iOS17 and iOS18.
I have connected multiple UWB Accessory by Accessory Single Configuration Data (UUID: 95e8d9d5-d8ef-4721-9a4e-807375f53328) in the APP.
In iOS17.5.1, the unconnected Accessory calls the func session in the NiSessionDelegate (_ session: NISession, didRemove nearbyObjects: [NINearbyObject], "reason: NINearbyObject RemovalReason)," reason is the timeout.
iOS18.0.1 does not call didRemove and fails to connect automatically after 10 minutes on the disconnected Accessory.
iOS18.2 does not call didRemove. After 10 minutes, when the Accessory is not connected, it automatically connects and starts ranging.
Therefore, I would like to ask what is updated in iOS18 UWB? Is there a document for reference, or can you provide the callback performance of each iOS version for UWB?
The code is as follows:
niConfiguration = try NINearbyAccessoryConfiguration(data: Data(AccessoryUwbConfigData))
uwbSession.run(niConfiguration)

We’ve set up an advanced App Clip experience that successfully launches when a user scans our QR code. However, the same App Clip invocation URL does not launch when tapping the associated Action Link on our Apple Place Card in Apple Maps. Instead of opening the App Clip, the link falls back to the website.
What We Have Done So Far:
App Clip Launched in App Store Connect: Our App Clip is approved and live on the App Store. Here is the invocation URL: https://appclip.parkzenapp.com/park?q=oJrbSIgx
Below is the QR code for our Advanced App Clip experience we are attempting to open in our Apple Maps Place card
When scanning the QR code that uses the same App Clip invocation URL, the App Clip reliably launches as expected. Here is our apple-app-site-association file, thats correctly served from the associated domain: https://appclip.parkzenapp.com/.well-known/apple-app-site-association
Add here is a screenshot showing how the appclip.parkzenapp.com domain is correctly validated.
Advanced App Clip Experience: We created and submitted an advanced App Clip Experience specifically tied to our location on Apple Maps. This App Clip Experience is approved and live. Below is an image of our set up of this Advanced App Clip Experience
Business Connect: We've created the Apple Maps Location in business connect and added the advanced App Clip experience invocation URL as an Action Link in the place card. See screenshot below.
Apple Maps Place:
https://maps.apple.com/place?auid=906421750045811407
Despite meeting these conditions, when a user taps the Action Link (the "Reserve" button in the Apple Maps Place Card), the fallback website opens rather than the App Clip.
Question:
What additional step or configuration might we be missing to ensure the Action Link on our Apple Maps place card triggers the App Clip instead of the website?
Thank you
If I change MKMapView's .preferredConfiguration property from .realistic to .flat, or .mapType from .hybridFlyover to .hybrid, subsequent scrolling causes a crash:
-[MTLDebugRenderCommandEncoder validateDrawIndexedPrimitives:indexCount:indexType:indexBuffer:indexBufferOffset:instanceCount:function:]:6179: failed assertion `Draw Indexed Primitives Validation
indexBufferOffset(0) + (indexCount(864) * 2) must be <= [indexBuffer length] (12).
For example, changing:
mapView.preferredConfiguration = MKHybridMapConfiguration(elevationStyle: .realistic)
to:
mapView.preferredConfiguration = MKHybridMapConfiguration(elevationStyle: .flat)
Then, scroll the map view, and it will crash. It is OK the other way around.
Or change:
self.mapView.mapType = .hybridFlyover
to:
self.mapView.mapType = .hybrid
I've tried everything I can think of, including calling functions like these after the change:
mapView.setNeedsDisplay()
mapView.setRegion(self.mapView.region, animated: false)
.mapType and .preferredConfiguration are settable properties, so they should be possible to change. I could create a new MKMapview, but I'd have to perfectly recreate the state which is not trivial and far from ideal.
I'm just trying to work around the issue FB14553276 so my map tiles don't show tiling seems in 2D which is a new issue introduced with iOS 18. This potential workaround still shows the seems in 3D, but is better than always showing seems. Seems like whatever I do, I just can't defeat MapKit bugs and puts me in an impossible situation. :(

Hi everyone,
I submitted a request for the Location Push Service Extension entitlement back in November. I received an acknowledgment email from Apple confirming they had received my request, but I never heard back. Assuming the November request might have been lost in the shuffle, I submitted another request in January. It's been a week since then, and I still haven’t received any response.
To follow up, I contacted Apple Support with my case number. Unfortunately, it seems they didn’t review the case properly, as the support assistant just sent me generic links about what to do when an app is rejected—which doesn’t apply here.
Has anyone else experienced similar delays with this entitlement? Could there be specific reasons for such delays? Any tips on how to escalate this or get it addressed effectively would be greatly appreciated.
Thank you in advance for your help!
Hello
I'd like to be able to rotate an mapkit.ImageAnnotation.
From this post on Stack Overflow https://stackoverflow.com/questions/78686475/need-to-style-a-mapkit-js-marker-annotation/78702266#78702266 I understand that it's possible, for example, to the following: map.annotations[0].element.style.cursor = "pointer"; and this works for me.
However, I need to do something like the following, but it doesn't work: map.annotations[0].element.style.transform = "rotate(90deg) ";
Any ideas how a mapkit.ImageAnnotation and mapkit.MarkerAnnotation can be rotated?
Thanks in advance
Sam
using the UseAnnotation in the map content does not show the blue user location. I added the info.plist info.

I am having issues loading in a mapkit snapshot. I get an error saying that https://domain.com and they're expecting domain.com. I have no idea what could be going wrong here. I set the domains properly in the mapkit tokens. When I click on the link it opens a new tab and loads what the data properly, but somehow in the application on production this error comes up.
Note: I have had issues with CMAltimeter since whats seems to have been a major undocumented modification since iOS 17.4.
So I'm using the CMAltimeter absolute locations delivery.
Sometimes, the altimeter seems to be in an uncalibrated mode and therefore, no altitude delivery happens.
Is there a way to be inform of such state? Currently, it just doesn't work and I can't inform the user about this. They just think the app is broken
What message should I give to the users to accelerate the calibration such that the CMAltimeter will work again?
Also, users have reported that the CMAltimeter can temporarily stop delivering altitude updates, even though it should.
So I guess my question resumes to this:
Whats the best practice to handle an uncalibrated CMAltimeter?
Thanks!
I'm currently developing an app with mapkit which I may submit to the Swift Student Challenge. So anyways, the app will be used completely offline. I was wondering if there was any way to include very low resolution map tiles with the app files. That way, the app never needs wifi. However, I'm not sure if this is possible, especially since the map would need to be under 20 mb. Thanks.

When I quit the app from the background task list, CLLocationUpdate.liveUpdates does not resume properly and start location updates. However, if I kill the app directly, it can recover and start location updates.

Hello everyone,
I'm encountering a strange location authorization issue in the iOS simulator, and I'm hoping someone can help me analyze it.
Problem Description:
When my app runs for the first time in the simulator, it requests location permissions.
I select "Deny" for the authorization.
Then, I go to the simulator's "Settings" -> "Privacy & Security" -> "Location Services" and enable location permissions for my app.
However, when I return to the app, CLLocationManager.authorizationStatus still returns .notDetermined, and the authorization request pop-up does not appear again.
This issue persists even after resetting the simulator settings multiple times.
import CoreLocation
@Observable
final class LocationManager: NSObject, CLLocationManagerDelegate {
var locationManager = CLLocationManager()
var currentLocation: CLLocationCoordinate2D?
override init() {
super.init()
locationManager.delegate = self
}
func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) {
let status = manager.authorizationStatus
print("Authorize Status: \(status)")
switch status {
case .authorizedWhenInUse, .authorizedAlways:
locationManager.startUpdatingLocation()
case .denied, .restricted:
stopLocation()
case .notDetermined:
locationManager.requestWhenInUseAuthorization()
print("Location permission not determined.")
@unknown default:
break
}
}
func requestLocation() {
let status = locationManager.authorizationStatus
if status == .authorizedWhenInUse || status == .authorizedAlways {
locationManager.requestLocation()
} else {
locationManager.requestWhenInUseAuthorization()
}
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
guard let newLocation = locations.first else { return }
currentLocation = newLocation.coordinate
print("Updated location: \(newLocation.coordinate)")
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print("Location update failed with error: \(error.localizedDescription)")
currentLocation = nil
}
func stopLocation() {
locationManager.stopUpdatingLocation()
print("Stopped updating location")
}
}

We have a PWA app developed by our company. In order to distribute this app to users' iPhones, we put this PWA app inside an XCode app. That means we put a WebView in XCode to display the PWA URL. Everything works perfect, except for location access.
The PWA app access the device location. When the first time the app acess location, it asks for user consent two times, by PWA app and by the XCode app. This is fine. When the user clicks Allow, the XCode app preserves the user choice and never asks again. However, the PWA app keeps on asking user permission every day. If we close the app open again, it will ask one more time. That means twice daily. But if we close and open the app for a third time, it will not ask. It remembers the user choice only for 24 hours.
If we install the PWA app directly in iPhone (that means if we add the URL as bookmark in home screen), it is asking for location permission only once. However, when we put this app inside an XCode app it is asking every day.
This affects the user experience, and as our users are not tech savvy, causing many issues. Is there a way to force the PWA app inside XCode app to remember the user choice?
Any help is very much appreciated.
Thanks,
Hello developers! I am working with a team of North Carolina State University researchers to create an app or program that can retrieve real-time traffic events, such as hazards, road closures, and road construction alerts, in a similar manner to the Apple Maps app, but with the added functionality of collecting them over a historical period given a start and end date.
I'm looking through the MapKit documentation, but there doesn't appear to be any functions exposing granular traffic data (i.e. road hazards), just travel times and level of congestion. Could anyone point me in the right direction? Is what I'm looking to do even possible using just Apple data?

Apple Feedback Ticket: FB16804936
Background
We develop a parental control application called Adora Kids (https://apps.apple.com/us/app/adora-kids/id6443787669) that requires "Location Always" permission to function properly. Our app has Screen Time authorization and provides monitoring services for parents.
Issue
We are experiencing a recurring problem where child users receive the system notification "Adora accessed your location in the background" every few days. This frequently results in children disabling location permissions, which prevents our app from functioning as intended.
Current Approach and Limitations
We have explored using Content & Privacy Restrictions for Location Services as a potential solution, but have encountered two significant limitations:
These restrictions cannot be accessed programmatically via the ManagedSettings framework (unlike AppStoreSettings and other restrictions).
The current implementation is "all-or-nothing" - enabling location restrictions blocks permission changes for ALL apps on the device, preventing children from granting legitimate location access to other applications.
Questions
Is there a way to programmatically access and manage Content & Privacy Restrictions for Location Services through the ManagedSettings framework that we might have overlooked?
Are there any recommended approaches for apps with Screen Time authorization to prevent users from changing specific permissions (particularly location) while still allowing them to manage permissions for other apps?
Does Apple have plans to implement app-specific permission locking for apps with Screen Time authorization in future iOS releases?
Are there any alternative approaches or workarounds that other developers have successfully implemented for this use case?
Any guidance from the developer community or Apple engineers would be greatly appreciated. This is a critical functionality issue affecting the reliability of our parental control service.
Thank you in advance for your assistance.

There is no official documentation specifying the exact criteria for determining a CLVisit.
For example, if a user starts at a target location, will the following method be called?
func locationManager(_ manager: CLLocationManager, didVisit visit: CLVisit)
This did not work during my testing.
It was only successfully triggered when starting from a distant location and arriving at the target point.
It would be helpful to know the exact conditions, such as how long a user must stay at a location for it to be considered a visit. Are there any specific thresholds (e.g., minimum duration, distance moved) that determine when this method is triggered?

It seems like find my mac is able to fetch the device location even if the device is in locked state. Why can’t other apps do the same.
Greetings,
I recently submitted a request for the Location Push Service Extension Entitlement.
Does anybody have insight into how long I would have to wait until Apple responds?
Thanks
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.
I am developing an iOS app that uses CLLocationManager to collect location continuously in both foreground and background. But it has the following 4 issues and I don’t understand why:
After a while of not using the app, I can not get location updates regularly. Even after that, I go into the app more often or even turn OFF and turn ON the permission again, but the problem still doesn’t improve until I reinstall the app.
Previously, I used SilentLog SDK to collect location. Since the cost was quite high, we developed our own SDK that also handles location tracking. After updating the app from the old version using SilentLog SDK to the new version using my own SDK, I can not get location updates regularly. However, when I reinstalled the app, it worked perfectly.
It seems that apps downloaded from TestFlight can get location more continuously than apps downloaded from the App Store
We sometimes encounter this error in the logs:
Error Domain=kCLErrorDomain Code=0 “(null)”
I think my app was not terminated in the background because I still collect location but it is not as frequent. I want to know if Apple has any mechanism to prevent such apps from getting location data continuously?
I use CLLocationManager with the following configuration:
self.locationManager.distanceFilter = 20
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager.allowsBackgroundLocationUpdates = true
self.locationManager.showsBackgroundLocationIndicator = false
self.locationManager.pausesLocationUpdatesAutomatically = false
I also filter the location updates using:
guard let location = locations.last else { return }
guard location.horizontalAccuracy <= 100 else { return }
guard location.speedAccuracy >= 0 else { return }
I use a background task to wake up the device every 15 minutes, and I also use silent push notifications in a similar manner. Each time the task is executed, I usually call stopLocation and then startLocation again. This happens quite frequently — will it have any impact or cause any issues?
