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?

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)

Hello (:
I’m working with MapKitJS and would like to render polylines that follow roads — similar to the behavior seen on maps.apple.com. While I can align polylines to roads manually, I haven’t found a way to render them below street names and road shields. Currently, all polylines appear above labels, which reduces readability when displaying routes in urban areas.
On maps.apple.com, polylines are rendered under street labels, which provides a much cleaner appearance. Is there a way to achieve this layering behavior in MapKitJS? If not, are there plans to support this kind of layer control in the future?
Thanks in advance!

Hello, I have noticed that some users have modified their real location through an app called "MGU" to bypass my app's security checks. I want to know how to protect my app and detect users using virtual location. I have reproduced the process of virtual positioning here:
Insert a plug-in through the interface at the bottom of the phone and connect it via Bluetooth on the phone
Set the desired positioning target on the "MGU" app
Turn off your phone's WiFi, network, and location for 10 seconds, then turn it back on
At this point, virtual positioning is successful.
Please assist me in troubleshooting this issue and inform me of the principle of implementing virtual positioning in this app and how to prevent it.
The following is the screen recording of virtual positioning operation:

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.
Hello,
I’ve done a lot of testing of location services running in background with various settings, but in all scenarios location updates pause after a couple of hours, especially overnight In sleep mode.
My app, for personal safety, requires regular location updates to 5m accuracy every minute. The only solution I have found is to keep the app in foreground.
Location always stops updating. Background mode stops updating. Live location services stops updating.
Is there a solution I may have missed other than keeping app in foreground?
thank you,

Hi Apple Dev Team & Community,
We’ve encountered an issue with background location updates when using an XCFramework we’ve built from our main app.
Context:
We have a standalone app called TravelSafely that reliably performs background location updates and alerts, even during sleep mode.
From this app, we extracted some core functionality into an XCFramework, including location management, and provided it as an SDK to a client.
We created a demo app to test this SDK in isolation.
Problem:
In the demo app, we notice that location updates work fine in the foreground.
However, in the background or sleep mode, location updates sometimes stop completely.
When we bring the app to the foreground again, location resumes.
This does not happen in the original standalone app.
What We’ve Already Checked:
UIBackgroundModes includes location
Info.plist has the required permissions
Location is started correctly using startUpdatingLocation
We maintain strong references and use background tasks as needed
Question:
Why would an app using a binary XCFramework (with location logic) behave differently from the original app in terms of background execution?
Is there any known issue or recommendation when working with SDKs/XCFrameworks that need to manage background tasks and location updates?
Any insights or recommendations to maintain proper background behavior would be highly appreciated.
Thank you!

Hello,
I upgraded my Apple Developer account from free to paid (Individual), but I cannot enable “Background Modes” (specifically “Location updates”) for any of my App IDs—including both old App IDs created while on the free account and brand new App IDs created after upgrading.
When I go to Apple Developer Portal > Identifiers > [select App ID] > Edit, the option for “Background Modes” is missing from the list of capabilities.
This is preventing me from enabling required entitlements for background location in Xcode, and all provisioning profiles fail with errors such as:
Provisioning profile "iOS Team Provisioning Profile: [my bundle id]" doesn't include the com.apple.developer.location.always and com.apple.developer.location.background entitlements.
Steps I’ve Taken:
Upgraded to a paid Apple Developer Program (verified in my account).
Created new App IDs after upgrading—Background Modes is still missing.
Created new Xcode projects with new App IDs and bundle identifiers—same result.
Refreshed provisioning profiles, cleaned Xcode, logged out/in—no change.
Contacted Apple Support; advised to file a Code-Level Support request, but the issue is with the portal/App ID capabilities, not my code.
My Question:
Has anyone experienced this issue where Background Modes capability is missing for all App IDs, even after upgrading to a paid account?
Is there any workaround, or does this require intervention from Apple Developer Support to “unlock” the missing capabilities for my developer account?
Any insight or advice would be appreciated!
Thank you.
In reference to this webpage, I'm turning my iPad to an iBeacon device.
class BeaconViewModel: NSObject, ObservableObject, CBPeripheralManagerDelegate {
private var peripheralManager: CBPeripheralManager?
private var beaconRegion: CLBeaconRegion?
private var beaconIdentityConstraint: CLBeaconIdentityConstraint?
//private var beaconCondition: CLBeaconIdentityCondition?
override init() {
super.init()
if let uuid = UUID(uuidString: "abc") {
beaconIdentityConstraint = CLBeaconIdentityConstraint(uuid: uuid, major: 123, minor: 456)
beaconRegion = CLBeaconRegion(beaconIdentityConstraint: beaconIdentityConstraint!, identifier: "com.example.myDeviceRegion")
peripheralManager = CBPeripheralManager(delegate: self, queue: nil, options: nil)
}
}
func peripheralManagerDidUpdateState(_ peripheral: CBPeripheralManager) {
switch peripheral.state {
case .poweredOn:
startAdvertise()
case .poweredOff:
peripheralManager?.stopAdvertising()
default:
break
}
}
func startAdvertise() {
guard let beaconRegion = beaconRegion else { return }
let peripheralData = beaconRegion.peripheralData(withMeasuredPower: nil)
peripheralManager?.startAdvertising(((peripheralData as NSDictionary) as! [String: Any]))
}
func stopAdvertise() {
peripheralManager?.stopAdvertising()
}
}
In Line 10, I'm using CLBeaconidentityConstraint to constrain the beacon. Xcode says that this class is deprecated and suggests that we use CLBeaconIdentityCondition. But if I try to use it, Xcode says
Cannot find type 'CLBeaconIdentityCondition' in scope
I've just updated Xcode to 16.4. I still get the same error. So how do we use CLBeaconIdentityCondition to constrain the beacon? My macOS version is Sequoia 15.5. Thanks.
I'm building a weather map that shows the rain on the map. I'm able to retrieve PNG images that are used as tiles to put onto the map. I then reload all the tiles on the map with each timeframe (tile set for every 10 minutes).
I'm able to get the map loaded up and I'm able to place the tiles and reload the data for each time slot. But I'm getting a ton of spam on the console every time the tiles are reloaded.
Failed to locate resource named "sky20Grey0@2x.png"

Yet the images are showing on the map just fine. But I feel like it's a bit sluggish due to all the spam coming out as I'm reloading this every 0.5 seconds with a timer.
I've tried to load the data from a remote server on demand by overriding the - (void)loadTileAtPath:(MKTileOverlayPath)path result:(void (^)(NSData *tileData, NSError *error))result function. But due to the timer this can lead to the data not getting loaded fully before it switches to the next time slot of data. I therefore pre-load everything. I can then store the NSData in memory and use loadTileAtPath or the NSURL to a stored file and use - (NSURL *)URLForTilePath:(MKTileOverlayPath)path. Both cases work. But both cases have this spam.
I've further refined things such that the MKTileOverlayRenderer is reused but that didn't help. Here's the function for that..
- (MKOverlayRenderer*)mapView:(MKMapView*)mapView rendererForOverlay:(id<MKOverlay>)overlay
{
if ([overlay isKindOfClass:[MKTileOverlay class]]) {
if (!self.rainRenderer) {
self.rainRenderer = [[MKTileOverlayRenderer alloc] initWithTileOverlay:overlay];
self.rainRenderer.alpha = 0.5;
}
return self.rainRenderer;
}
return nil;
}
I'm using one MKOverlay and then just reloading the tiles as needed. Otherwise there is quite a pronounced flicker. Here's that function which is triggered by the NSTimer to happen every 0.5 seconds.
- (void) updateRainFrame {
self.currentFrameIndex = (self.currentFrameIndex + 1) % self.timestamps.count;
if ((self.currentFrameIndex >= 0) && (self.timestamps.count > self.currentFrameIndex)) {
NSLog (@"self.currentFrameIndex = %lu", self.currentFrameIndex);
NSString *timestamp = self.timestamps[self.currentFrameIndex];
[self.overlay setTimestamp:timestamp];
[self.rainRenderer reloadData];
}
}
In that function I'm updating the "timestamp" in the overlay which is the time slot that contains all the tiles for that time. This way my overridden MKTileOverlay can then pass the correct path for the tiles. For example for loading from a file:
- (NSURL *)URLForTilePath:(MKTileOverlayPath)path {
return [self getWeatherTileFileURLForPath:path];
}
Or NSData stored in memory
- (void)loadTileAtPath:(MKTileOverlayPath)path result:(void (^)(NSData *tileData, NSError *error))result
{
return [self getWeatherTileDataForPath:path];
}
But no matter which way I use I keep getting this spam and unfortunately there is no error or anything to point to why it is spamming out.
Also the tiles themselves are PNG files either 256x256 or 512x512 in pixel size.
I saw that this could be something to do with Metal but I'm assuming that's something that MapKit uses.
Very much welcome any thoughts to what could be causing this?
Hi, I am using Location Push Service Extension in my app but as soon as my app gets an update Location Extension fails to launch. From the console I can see OS is terminating this process. What could be the reason ? When user launches the app after update the extension starts to work as expected.
I have a Nissan Rogue 2021 and iPhone 14 Pro Max. Carplay was working fine until I decided to update to the new beta program and now my carplay does not seem to want to operate at all. I do the fixes online suggest in rebooting both systems, forgetting entirely and reconnecting. In the process of doing so, I can get the prompts to start with "Allow while unlocked?" But once selecting that I am unable to actually use the Carplay from the phone. It doesn't even give option to switch to it when I attempt to change audio output.
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?
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!
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?
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.

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!
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.
