SwiftUI creating MapCameraPosition from CLLocationManager initialiser/self error when trying to tie them? (see code)
Trying to use new Swift @Observable to monitor GPS position within SwiftUI content view. But how do I tie the latest locations to the SwiftUI Map's mapCameraPosition? Well ideally the answer could cover: How to fix this error - So get map tracking along with the User Position, but also How to include facility to turn on/off the map moving to track the user position (which I'll need to do next). So could be tracking, then disable, move map around and have a look at things, then click button to start syncing the mapcameraposition to the GPS location again Refer to error I'm embedded in the code below. import SwiftUI import MapKit @Observable final class NewLocationManager : NSObject, CLLocationManagerDelegate { var location: CLLocation? = nil private let locationManager = CLLocationManager() func startCurrentLocationUpdates() async throws { if locationManager.authorizationStatus == .notDetermined { locationManager.requestWhenInUseAuthorization() } for try await locationUpdate in CLLocationUpdate.liveUpdates() { guard let location = locationUpdate.location else { return } self.location = location } } } struct ContentView: View { var newlocationManager = NewLocationManager() @State private var cameraPosition: MapCameraPosition = .region(MKCoordinateRegion( center: newlocationManager.location?.coordinate ?? <#default value#>, span: MKCoordinateSpan(latitudeDelta: 0.25, longitudeDelta: 0.25) )) // GET ERROR: Cannot use instance member 'newlocationManager' within property initializer; property initializers run before 'self' is available var body: some View { ZStack { Map(position: $cameraPosition) Text("New location manager: \(newlocationManager.location?.description ?? "NIL" )") // works } .task { try? await newlocationManager.startCurrentLocationUpdates() } } } #Preview { ContentView() }

Requirement of location services to prevent fake orders
Hi all, I have a delivery app that requires the user's location on start up. For example to determine the list of services available to the user. So on start up the app asks for location permission. While the app does have a concept of creating addresses, we still require location services so that the user can only select an address close to their current GPS. This is done to prevent fake orders, many apps with similar functionality allow you to pick any location on the map even if you decline location services, which in turn causes a lot of trouble since there are constantly fake orders being created. So to counter that we're asking for the user's location. Now my question is: will apple force me to absolutely never require location access or will explaining to them the problem of fake orders allow me to pass the review? Another feature I have is a driving mode, it's a map for drivers to see routes to a specific order. Obviously I need location services for that to function, or will Apple's review team also cling to that and force me to implement some weird way of letting the user choose their current location? Because there are a lot of trolls that create fake orders, and then have 20 delivery drivers come to a place in a middle of a road. This is a serious issue and will literally kill our business if not countered somehow.

IOS 18 is blocking GPS connectivity for Waze/Google Maps…
On IOS 18, starting October this year, the location is not syncing in real time.You might drive for several kilometers and the location displayed on Waze will remain on the same position.This might put in position to miss the exit on the highway and have to drive another 40/50 km, lose time and energy, to get back in the original track. Reinstall the application twice is not correcting the behavior, as well as changing the device, the same issue is present on iPhone 16. Waze support team shared the following: ”Hey there! We'd like to apologize for any hassle that this has caused you. This article: https://tinyurl.com/3fu88jwj might help solve your issue. If you still need help, please open a support ticket by copying and pasting this link: https://tinyurl.com/mrx77ukz in a web browser, and someone from the team will get back to you soon." Based on the above facts, this is clearly an IOS 18 issue, that needs to be prioritized.

didEnterRegion and didExitRegion delegate methods are called twice
When I set the values of notifyOnExit and notifyOnEnter to true when registering CLCircularRegion, I checked that the didExitRegion and didEnterRegion functions are called well. However, there is a problem that they are called twice in a row every time they are called. I was wondering if this is an internal bug in the API. There is also a stackoverflow report related to the above issue. I would appreciate your confirmation. stackoverflow - why the didEnterRegion called twice? Thank you.

App Clip Not Launching From Approved Apple Maps Action Link
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

New CoreLocation APIs
Hi All, I am currently working on an app that has some navigation functionality, and since my minimum iOS is 18 wanted to incorporate the new APIs that yield a AsyncStream of locations. I have watched both WWDC sessions, the one where the new API is introduced to retrieve the location points, and also the other video where the new authorization process for location is simplified as well. I have an app currently working in its current state, but am noticing some weird quirks when using the CLBackgroundActivitySession to get the elevated background permission. What I am doing here is to create this stream and the background object is below: return AsyncThrowingStream { continuation in let task = Task { do { for try await update in CLLocationUpdate.liveUpdates(updateType) { if shouldStopUpdate { continuation.finish() break } continuation.yield(update) } } catch { continuation.finish(throwing: error) } } state = .started(locationTask: task, background: CLBackgroundActivitySession()) } When I have an active navigation session going and am strongly holding this object and the user force quits the app (or I stop the target through Xcode) the navigation activity indicator in the status bar (or dynamic island) remains present. Even if I relaunch the app, start navigation again, and then call the invalidate method on the CLBackgroundActivitySession I then am seeing that navigation indicator even if I delete my app, and often need to do a full restart to get out of this state. Is there a step I am missing, or do I not understand the way the new API works to run in the background?

Location Push Service Extension in Limbo
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!

iOS 18: startRangingBeacons Stops When Display is Off in Background (Worked on iOS 17.2.1)
Issue Summary After calling startRangingBeacons, the didRangeBeacons delegate method does not receive iBeacon scan data when the device display is turned off in the background. Expected Behavior On iOS 17.2.1 (iPhone 14), beacon ranging continues in the background even when the display is turned off. The same behavior is expected on iOS 18, but it is not working as intended. Observed Behavior On iOS 18, once the display turns off, beacon ranging stops, and the didRangeBeacons method is not triggered until the display is turned back on. • Location permission is set to “Always Allow.” • Background Modes are correctly configured (Location Updates enabled). Steps to Reproduce Ensure location permission is set to Always Allow. Enable Background Modes → Location Updates in Xcode settings. Call startRangingBeacons(in:) in the app. Put the app in the background and turn off the display. Observe that didRangeBeacons is not triggered while the display is off. Additional Notes • The issue does not occur on iOS 17.2.1 (iPhone 14), where beacon ranging continues even with the display off. • This behavior change is observed on iOS 18 across multiple devices. Could you confirm if this is an intended change in behavior or a bug? If this is expected behavior, what alternative approach is recommended to maintain continuous beacon ranging when the display is off in the background?

Underground location (in subway) doesn't update properly
We (at the NYC MTA) are building a new subway/bus app and diving deep into location tracking on iOS. We’re encountering an issue with how Core Location functions in the subway, specifically regarding how long it takes to update a passenger’s location as they travel from station to station. As an example, please see this video: https://drive.google.com/file/d/1yaddkjyPEETvTEmClPAJ2wks8b-_whqB/view?usp=sharing The red dot is set manually (via a tap gesture) and represents the ground truth of where the phone actually is at that moment. The most critical moment to observe is when the train physically arrives at a station (i.e., when I can see the platform outside my window). At this moment, I update the red dot to the center of the station on the map. Similarly, I adjust the red dot when the train departs a station, placing it just outside the station in the direction of travel. The trip shown is from Rector St to 14 St. All times are in EST. I’d like to investigate this issue further since providing a seamless underground location experience is crucial for customers. As a point of comparison, Android phones exhibit near-perfect behavior, proving that this is technically feasible. We want to ensure the iOS experience is just as smooth.

Simulator Location Authorization Issue: Authorization Status Remains notDetermined After Denying and Changing in System Settings
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" -&gt; "Privacy &amp; Security" -&gt; "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") } }

MapPolygon
I recently converted over my map from Mapbox Maps to MapKit Map. I have been able to add my polygons on the Map using MapPolygon. The issue I am having is being able to select the Polygon to be able to view information about the polygon. Has anyone been able to figure out a way to tap on the Polygon? I have tried selection but the Polygon doesn't recognize the tap. I would really appreciate it if anyone could point me in the right direction of how I can accomplish this.

Location Push Extension Cannot Wake after 10 mins
Hi team, I'm developing a feature that's collecting the device locations for home security app. We've been following https://developer.apple.com/documentation/corelocation/creating-a-location-push-service-extension apns-push-type set to location. apns-priority set to 5. during testing, we found that the device's notification extension cannot be triggered after device going into lock screen for 10 mins. Wonder should we set the priority to 10? Thanks!

The App Remembers Location Access Permission only for 24 Hours
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,

How to update business information on Apple Maps Ukraine?
Hello everyone, I need help updating business information on Apple Maps for locations in Ukraine. Unfortunately, the usual methods, like "Report an Issue" in the Maps app or using Apple Business Connect, don’t seem to be working properly for Ukrainian businesses. Many locations have outdated or missing details, which is frustrating for both business owners and customers. Given the current situation, keeping information accurate is more important than ever. Has anyone successfully updated business listings in Ukraine recently? If so, could you share the process or any contacts that might help? Any advice would be greatly appreciated! Thanks in advance!

Can I use ARGeoAnchor with simulated locations
I'm trying to evaluate if we can support AR navigation with MapKit. The feature is supposed to be available for users in US. I tried to run the sample on my iPhone: https://developer.apple.com/documentation/arkit/tracking-geographic-locations-in-ar?language=objc But I'm in a location that ARGeoTrackingConfiguration.checkAvailabilityWithCompletionHandler: always return false. I think ARGeoAnchor isn't supported in my location. I tried to use simulated locations by Adding a gpx file when launching the app. Enabling Xcode -> Debug -> Simulate Location -> New York, NY, US But the availability for ARGeoAnchor is still false. Is that possible for me to develop the ARGeoAnchor feature outside of the covered areas?

Notification Delivery Issues for Location Push Service Extension
We are currently testing the implementation of our Location Push Service Extension (LPSE) in both Ad Hoc and Release environments. We have encountered an issue where LPSE notifications, which were previously working correctly, suddenly fail to be delivered on some devices. After a period of several hours, the notifications resume arriving, but the issue remains intermittent. Notably, during these periods of suspected delivery restriction, regular push notifications (e.g., those using apns-push-type: alert) are delivered and displayed without any problem. [Detailed Situation] Test Environment and Scope We are testing LPSE after obtaining the necessary entitlements, in both Ad Hoc and Release environments. The issue is not observed on all test devices; only certain devices are affected. Observed Behavior Under normal circumstances, LPSE notifications are received and the extension is activated; however, on some devices the notifications suddenly stop arriving. During these periods, even when sending notifications with apns-push-type: location directly via the CloudKit Push Notification Console, no response is observed on the affected devices. The APNs server (api.push.apple.com) always returns a 200 OK response via HTTP/2, and our server-side logs and configurations (DNS resolution performed on every request, using the same JWT token for 59 minutes per session, communication via HTTP/2 with ALPN Protocol: h2) show no issues. Other app functionalities (network communication, UI responsiveness, etc.) work normally. Sending content When sending notifications from our server to APNs (api.push.apple.com), we use the following configuration (over HTTP/2): const payload = { aps: { 'content-available': 1 } }; const headers = { ':method': 'POST', ':path': /3/device/${apnsToken}, 'Authorization': bearer ${jwtToken}, 'apns-topic': 'ot.Here.location-query', 'apns-priority': '10', 'apns-push-type': 'location', 'Content-Type': 'application/json' }; We perform DNS resolution for every request, use the same JWT token for a 59-minute period per session, and communicate via HTTP/2 with ALPN Protocol: h2. Hypothesis on the Cause We suspect that due to an implementation issue, silent push notifications (using content-available: 1) were being sent every few minutes concurrently, which may have triggered an APNs delivery restriction (rate limiting). As a countermeasure, we have completely stopped sending silent pushes and any other background notifications aside from LPSE; however, the issue persists. Additionally, even after resetting affected devices, the delivery problem continues to occur. [Questions for Diagnosis] Given the above situation, is it reasonable to suspect that excessive silent push notifications have triggered an APNs delivery restriction? Does such a silent push restriction affect LPSE notifications (i.e., those sent with apns-push-type: location)? Do APNs delivery restrictions persist even after a device has been reset? Can a high volume of LPSE notifications alone (without silent pushes) also trigger a delivery restriction? → This is our primary concern since it poses a significant implementation challenge. Please let us know if any additional information is required for diagnosis.

Can a Location-Based Audio AR Experience Run in the Background on iOS?
Hi everyone! I’ve developed a location-based Audio AR app in Unity with FMOD &amp; Resonance Audio and AirPods Pro Head-Tracking to create a ubiquitous augmented soundscape experience. Think of it as an audio version of Pokémon Go, but with a more precise location requirement to ensure spatial audio is placed correctly. I want this experience to run in the background on iOS, but from what I’ve gathered, it seems Unity doesn’t support this well. So, I’m considering developing a Swift version instead. Since this is primarily for research purposes, privacy concerns are not a major issue in my case. However, I’ve come across some potential challenges: Real-time precise location updates – Can iOS provide fully instantaneous, high-accuracy location updates in the background? Continuous real-time data processing – Can an app continuously process spatial audio, head-tracking, and location data while running in the background? I’m not sure if newer iOS versions have improved in these areas or if there are workarounds to achieve this. Would this kind of experience be feasible to run in the background on iOS? Any insights or pointers would be greatly appreciated! I’m very new to iOS development, so apologies if this is a basic question. Thanks in advance!
