Hi all,
We’re running into a challenge with our iOS app DriveSmarter, which uses background location updates when connected to a physical Bluetooth device (e.g., dash cam, radar detector). For battery efficiency, we disable location services in the background when no device is connected. The problem we’re now facing is:
How can we programmatically re-enable location services when a Bluetooth device reconnects while the app is still in the background?
From what I understand, Core Location doesn’t allow re-enabling background location updates unless the app returns to the foreground. But our core use case requires this to happen seamlessly in the background when the user starts driving and the device connects again.
To clarify:
We stop location updates when the device disconnects.
We want to resume location updates only when the device reconnects, even if the app is still in the background.
Manually bringing the app to the foreground is not a reliable or user-friendly option.
So my questions:
Is it possible to programmatically restart background location services upon a Bluetooth connection event while staying in the background?
If not, are there any best practices or Apple-recommended alternatives to achieve a similar result?
Any guidance, patterns, or creative solutions would be greatly appreciated!
Thanks in advance
I’ve just updated to Simulator 16.0 (104.1)
I’m currently developing my first app, which relies heavily on location data. It was simulating correctly before I updated Simulator. Since the update it is no longer receiving location data.
Is anyone else experiencing this problem?
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!
The other day I was playing with iBeacon and found out that CLBeaconIdentityConstraint will be deprecated after iOS 18.5. So I've written code with BeaconIdentityCondition in reference to this Apple's sample project.
import Foundation
import CoreLocation
let monitorName = "BeaconMonitor"
@MainActor
public class BeaconViewModel: ObservableObject {
private let manager: CLLocationManager
static let shared = BeaconViewModel()
public var monitor: CLMonitor?
@Published var UIRows: [String: [CLMonitor.Event]] = [:]
init() {
self.manager = CLLocationManager()
self.manager.requestWhenInUseAuthorization()
}
func startMonitoringConditions() {
Task {
print("Set up monitor")
monitor = await CLMonitor(monitorName)
await monitor!.add(getBeaconIdentityCondition(), identifier: "TestBeacon")
for identifier in await monitor!.identifiers {
guard let lastEvent = await monitor!.record(for: identifier)?.lastEvent else { continue }
UIRows[identifier] = [lastEvent]
}
for try await event in await monitor!.events {
guard let lastEvent = await monitor!.record(for: event.identifier)?.lastEvent else { continue }
if event.state == lastEvent.state {
continue
}
UIRows[event.identifier] = [event]
UIRows[event.identifier]?.append(lastEvent)
}
}
}
func updateRecords() async {
UIRows = [:]
for identifier in await monitor?.identifiers ?? [] {
guard let lastEvent = await monitor!.record(for: identifier)?.lastEvent else { continue }
UIRows[identifier] = [lastEvent]
}
}
func getBeaconIdentityCondition() -> CLMonitor.BeaconIdentityCondition {
CLMonitor.BeaconIdentityCondition(uuid: UUID(uuidString: "abc")!, major: 123, minor: 789)
}
}
It works except that my sample app can take as long as 90 seconds to see event changes. You would get an instant update with an fashion (CLBeacon and CLBeaconIdentityConstraint). Is there anything that I can do to see changes faster? Thanks.
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.
Is there a way to simulate altitude, longitude and latitude using the API?
For now I only found longitude and latitude to be simulated.

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,
Brendan
We are currently experiencing a very interesting issue when accessing the location in the background with CLLocationManager.
The user has given our app the "whenInUse" permission for locations and in most cases the app provides location updates even when it's in the background.
However, when we started to use other navigation apps in the foreground we saw that the func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) method was called with (kCLErrorDomain error 1.).
The user hasn't changed the location permission and we saw that locations were delivered once the user opened the app again.
I don't see anything in the documentation explaining this issue, but I chatted with other developers that confirm that specific behavior.
Am I missing something here?
We have background location updates enabled in our app that updates the location on our servers to deliver realtime weather alerts. We see that we are receiving these location updates when the app is backgrounded by the user.
However, when the user removes our app from the background using the App Switcher, we no longer see notifications happening. We have the app delegate's "didFinishLaunchingWithOptions" method setup to check for .location in the launch options, and start location tracking immediately.
Is it the intention of the OS to no longer send our app background location updates if the user manually removes our app from the background?

Summary
The onLongPress callback on MapViewcomponent is not working on iOS devices. The callback is properly implemented but never gets triggered on iOS, while it works as expected on Android.
Reproducible sample code
<MapView
onLongPress={(e) => {
console.log("onLongPress", e);
setAddLocation(e.nativeEvent.coordinate);
}}
// ... other props
Steps to reproduce
Just put onLongPress callback on MapView and notice it won't be triggered.
Expected result
Long press on the map should trigger the onLongPress callback
The callback should receive the event object with coordinates
Actual result
Long press on the map does not trigger the callback on iOS
No console logs are shown when long pressing
The functionality works as expected on Android

Hello,
I'm encountering a runtime crash when building my visionOS app with Xcode 16.3 for visionOS 2.5. Our existing AppStore/Testflight app is also instantly crashing on visionOS 2.5 when opened but works fine on e.g visionOS 2.4.
The app builds successfully but crashes on launch with this symbol lookup error (slightly adjusted because the forum complained regarding sensitive data):
Symbol not found: _$sSo22CLLocationCoordinate2DVSE12CoreLocationMc
Referenced from: <XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX> /private/var/containers/Bundle/Application/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/MyApp.app/MyApp.debug.dylib

I've already implemented my own Codable conformance for CLLocationCoordinate2D:
extension CLLocationCoordinate2D: Codable {
// implementation details...
}
This worked fine on previous visionOS/Xcode versions. Has anyone encountered this issue or found a solution?
System details:
macOS version: 15.3.2
Xcode version: 16.3
visionOS target: 2.5
Thank you!
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.
I am using CLLocationUpdate.liveUpdates() to build a location sharing app. Most of the time it works fine, including in the background, giving acceptably frequent updates. However, soon after the user puts their phone away for the night, the updates stop coming.
I've checked all the instance properties (.stationary, .locationUnavailable, etc.) but none of them are ever set to true, even for the last update before updates end.
Is there some way to keep the updates coming through the night?
I've included some relevant parts of my code here:
func startLocationUpdates() {
if self.manager.authorizationStatus == .notDetermined {
self.manager.requestWhenInUseAuthorization()
}
Task {
do {
self.background = CLBackgroundActivitySession()
self.session = CLServiceSession(authorization: CLServiceSession.AuthorizationRequirement.always)
let updates = CLLocationUpdate.liveUpdates()
for try await update in updates {
if let loc = update.location {
BackgroundServiceKt.onLocationUpdate(arg: loc)
}
// check all the instance properties
}
} catch {
// error
}
return
}
}
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
LocationsHandler.shared.startLocationUpdates()
return true
}
}
Hello,
I'm experiencing an issue with the Apple Maps URL scheme when using raw latitude and longitude coordinates in the daddr parameter.
Until recently, using a URL like this worked reliably:
https://maps.apple.com/?daddr=37.7749,-122.4194
This would open Apple Maps and show directions from the current location to the specified coordinates.
However, on recent iOS versions, this URL no longer behaves as expected.
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?
We have a setup that's really close to the one used in the example project - Monitoring location changes with Core Location.
In short, we have a flag that indicates whether or not we should start background location monitoring. If the flag is on, after the app starts, we
Create a CLServiceSession with authorization: .always
Create a CLBackgroundActivitySession
The user can perform an action (press a button) to toggle the flag off, in which case we invalidate and dispose of the CLServiceSession and CLBackgroundActivitySession instances and cancel any liveUpdates observation.
So far, so good, everything works as expected.
However, we're experiencing a weird behavior on iPhones with Dynamic Island after there's an app update.
When the user is on the same app version, the behavior is correct.
have the flag on,
background location monitoring works fine,
when the app is in the the background, there's correctly a location indicator in Dynamic Island
the user can go back to the app and turn the flag off (disposing of instances, cancelling location observation), and when the app is in the background, there is no location indicator in Dynamic Island
The problem arises when the user updates the app
open version 1.0 of the app
have the flag on,
background location monitoring works fine,
when the app is in the the background, there's correctly a location indicator in Dynamic Island
download an app update - version 2.0
the app restarts, didFinishLaunchingWithOptions gets called again and we start the background services
dynamic island indicator is correctly showing a location indicator
the user goes into the app, toggles the flag off - turning location observation off, we dispose of everything
now, when the app is moved to the background, there's still a location indicator in the Dynamic Island, even though we're no longer observing location
The indicator is hard to get rid of, there are only 2 ways we've found
restart the device, or
uninstall the app
The question is - is this a bug in the system? Or is there anything we should be doing actively after an app update?
Thank you!
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:

Hello (:
I have a question regarding the current pricing model for Apple Maps APIs, specifically MapKitJS, the Maps Snapshot API, and the Maps Server API. Previously, the documentation and my understanding indicated that the usage limits were defined per day — for example, 250,000 map loads per day for MapKitJS and 25,000 snapshots per day. However, in the Apple Developer Dashboard, I’m now seeing these limits shown on a per-month basis, such as only 25,000 snapshots per-month. This appears to contradict the publicly available information on the official website, which still states daily limits. Has the pricing model officially changed, or is this just a display issue in the dashboard?
I need to know this because we're going into release soon, and then we might have thousands of users.
