CarPlay Display Issue: Missing Images After Extended Navigation
I am experiencing a persistent issue with my CarPlay application where images rendered within the CarPlay Template interface disappear after the application has been used for an extended period, typically during prolonged navigation. Images used directly within the CarPlay Template framework disappear. In the attached image showing the issue (IMG_1022.PNG), you can see that the icons for 'parking', 'gasstation', 'conveniencestore', and 'favoritespot' are missing. The side bar icons (car, battery, etc.) remain visible, and the text labels are present, but the Template-specific images/icons vanish. Problem Description Images displayed on a custom UIViewController remain visible. Some of our screens integrate a UIViewController (e.g., for map display), and any images rendered on that view controller (not the template itself) continue to display correctly without issue. Example Images IMG_1021.PNG (Normal/Correct Display): This image shows the SearchMenu screen with all icons displayed correctly next to their respective labels ('word', 'home', 'route', 'history', 'parking', 'gasstation', 'conveniencestore', 'favoritespot'). IMG_1022.PNG (Problem State): This image shows the same screen after prolonged use, where the icons next to 'parking', 'gasstation', 'conveniencestore', and 'favoritespot' have disappeared, leaving only the text labels. Question Has anyone encountered a similar issue? This seems to be a rendering or resource management problem specific to images within the CarPlay Template components when the application runs for an extended duration.

How can I keep my app running in the background even after it has been force‑killed?
Recently I noticed an app called “Lookus”. Even if I force‑kill it, it still seems to obtain information such as my charging status and network status, and it can even send real‑time notifications. I’m curious how this is technically possible. Does anyone know how this could be achieved?

Altitude for MKAnnotation
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?

Snippet Intents and location
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

Where is Find My network Supplementary Agreement?
I am new to Find My network development and i am going to use Nordic solution for my FMN application. I have asked the MFi representative to enable the "Find My network" in our MFi portal. But there are just a sets of PDF in the "Find My network" under "Technology" in MFi Portal. Is there any Find My network Supplementary Agreement in MFi portal? Is it a PDF or where can i find it? Because I need to sign this document back to Nordic solution representative. But it seems there are no such FMN Supplementary Agreement.

iPad Compass Calibration Issues: Impact of Magnetic Cover
We have developed an iPad application using the ARCL (AR + CoreLocation) library to render Point of Interest (POI) annotations in both an AR view and a standard MapView. The application performs as expected on standard devices. However, we have some iPad covered with strong magnet. This creates significant magnetic interference, resulting in a 90° to 180° heading offset, rendering the AR POI placement and MapView orientation unusable. Technical Challenges & Constraints: Hardware Lock: The magnetic cover is a mandatory business requirement and cannot be removed during field use. Sensor Failure: The internal magnetometer cannot provide an accurate North reference due to the proximity of the cover’s magnets. While CoreLocation and CoreMotion use sensor fusion, the magnetometer remains the primary source for absolute heading. Alternative Orientation Tracking: Is there a documented method to bypass the magnetometer and derive device orientation using only the Gyroscope and Accelerometer (e.g., relative tracking) while still maintaining alignment with geographic coordinates in CoreLocation? Programmatic Offsets: Are there known APIs or mathematical workarounds to programmatically "nullify" or offset a constant magnetic bias once the device is inside the cover? so we can use that offset for ARView and in Mapview as well.

Question about MFi token access
Hi all, Our company is applying for the Find My certification for our smartwearable product. Now we submitted the product plan and it's approved. The lab asked us to get the token but we searched on internet and the documents about it are limited. The CSR has approved and we already had .pem and .key file. I wonder what should we do next. Any helps are appreciated

CLMonitor API Missing Geofence Entry Events After Initial Registration
We are experiencing a failure in CLMonitor event delivery when the application is launched into the background via an APNS (Remote Push Notification). Even when a CLBackgroundActivitySession is instantiated immediately upon background launch, CLCircularGeographicCondition "Enter" events are suppressed. The system fails to deliver these events until the user manually brings the application to the Foreground. This indicates that CLBackgroundActivitySession does not correctly maintain background persistence when the session begins in a background state rather than transitioning from the foreground. Comparison of API Behavior (Background State) Launch via APNS: CLMonitor: Fails to trigger "Enter" events until the app is manually brought to the foreground. Legacy API: Successfully triggers and delivers "Enter" events immediately upon background launch. Exit Event Reliability: CLMonitor: Reliably triggers exit events even in the background. Legacy API: Reliably triggers exit events. Foreground Dependency: CLMonitor: Requires a foreground transition to "flush" or activate the delivery of pending entry events. Legacy API: No foreground transition required; events are delivered directly to the background process. Event Recovery: CLMonitor: Relies on the developer re-instantiating the CLMonitor and awaiting the events stream, which appears to "stall" during warm-starts. Legacy API: Relies on the CLLocationManagerDelegate which remains active as long as the manager instance exists. Steps to Reproduce Preconditions: Location Permissions: Set to "Always Allow". Background Modes: "Location updates" and "Remote notifications" enabled. App State: Terminated or Killed (by the user or the OS). Reproduction Path: Trigger Background Launch: Send a silent push notification (APNS) to wake the app in the background. Initialize Session: Within the background launch sequence (e.g., didFinishLaunchingWithOptions), immediately create and hold a strong reference to a CLBackgroundActivitySession. Register Monitor: * Initialize CLMonitor using requestMonitorWithConfiguration. Add a geofence using addConditionForMonitoring with a CLCircularGeographicCondition. Simulate Entry: Move the physical device (or simulate location) into the geofence boundary while the app remains in the background state. Observe: No "Enter" event is received in the CLMonitor event stream. Foreground Transition: Bring the app to the foreground. Actual Result: The "Enter" event is only delivered the moment the app enters the Foreground. Expected Result: The CLBackgroundActivitySession should enable CLMonitor to deliver "Enter" events immediately in the background, parity with the deprecated startMonitoringForRegion API.

Clarifying the intended scope of DL-TDoA ranging in Nearby Interaction
Does DL-TDoA ranging in the Nearby Interaction framework support building a traditional RTLS-style TDoA localization system, where a device’s absolute position is computed from time-difference measurements across multiple deployed anchors, or is DL-TDoA strictly limited to system-managed, relative ranging and direction estimation (distance/direction) between nearby devices? If DL-TDoA ranging in Nearby Interaction is not intended to support traditional RTLS-style TDoA localization, is there any public documentation or reference material that describes the intended DL-TDoA architecture, such as the expected system setup, device roles, and deployment constraints (for example, how ranging is expected to be performed between an iPhone and nearby accessories), beyond the high-level API documentation? Regards.

The Example App for Monitoring Location Changes Doesn't Work
Downloaded example app from here Xcode version: Version 26.1.1 (17B100) Simulator iOS Version: 26.1 & 18.5 Set custom location in the simulator to the center of the condition being monitored in the example. The only log entry was "Setup Monitor". Tried a custom gpx starting at the same point and moving 500m away. Same logs. Didn't change any of the source code, granted always permissions, allowed notifications, tapped "AddCircularGeographicCondition". Let me know if there is something I am missing or more information I can provide.

iOS suspends app after BLE discovery even though I start Always-authorized location udpates (Target deployment: 16.3+)
I’m hitting a specific edge case with background execution that I can’t figure out. I'm using Flutter for the UI, but all the logic handles are in Swift using CoreBluetooth and CoreLocation. I need the app to wake up from a suspended state when it detects my specific BLE peripheral (OBD sensor), connect to it, and immediately start continuous location tracking for the duration of the drive. If I start this process while the app is in the foreground, or very shortly after going to BG, it works perfectly. The app stays alive for the whole trip. The issue only happens when the sequence starts from the background: The app is suspended. scanForPeripherals wakes the app when the sensor is found. In didDiscover, I immediately call locationManager.startUpdatingLocation(). locationd actually delivers updates successfully. However, 5-15 minutes later, iOS suspends the app again. Crucially, I never see the blue "Location In Use" pill on the status bar, even though I have showsBackgroundLocationIndicator = true set. Also, distance filter is set to None. Logs for reference (around suspending) locationd: {"msg":"Sending location to client","Client":"[appName]:","desiredAccuracy":"-1.000000"} runningboardd: Invalidating assertion ... from originator \\\[osservice<com.apple.bluetoothd>:...\\\] runningboardd: Removed last relative-start-date-defining assertion for process app<[appName]...> runningboardd: Calculated state ... running-suspended runningboardd: Suspending task locationd: Client [appName]: disconnected bluetoothd: State of application "[appName]" is now "suspended" Questions Why does invalidating the Bluetooth assertion cause an immediate suspend even though I called startUpdatingLocation() and am receiving updates? Does the missing blue location pill imply that the OS never fully "accepted" the location session? Is there a specific "handshake" required to transition from a BLE wake-up to a long-running location session? I'm wondering if I need to use a background task identifier to bridge the gap between the BLE wake and the location manager taking over. More context: Digging deeper in the comments, I just noticed the following patterns when the application is not suspended vs when it is recently suspended and got awaken by a BLE event. Not suspended: 303948:Jan 23 20:59:35.640118 locationd[6491] <Debug>: {"msg":"Client is setting ContinuousBackgroundLocationRequested", "Client":"[appName]:", "ContinuousBackgroundLocationRequested":1} 303949:Jan 23 20:59:35.640155 locationd[6491] <Debug>: {"msg":"Allowing process assertion due to foreground-ish status", "ClientKeyPath":"[appName]:"} Recently suspended and awaken by BLE: 564296:Jan 23 21:00:23.179125 locationd[6491] <Debug>: {"msg":"Client is setting ContinuousBackgroundLocationRequested", "Client":"[appName]:", "ContinuousBackgroundLocationRequested":1} 564298:Jan 23 21:00:23.179195 locationd[6491] <Notice>: {"msg":"#Warning Denying process assertion", "ClientKeyPath":"[appName]:"} The assertion fails for the second case and that's why the app could not persist. Most importantly, following the logs in the second case, I see the following: locationd[6491] <Notice>: {"msg":"computing freshAuthorizationContext", "Client":"[appName]:", "ClientDictionary":"{\n AlwaysServiceSession = 0;\n I suspect that the flag AlwaysServiceSession being 0 has to do with process assertion being denied for location.

why mapkit js does not have LookAroundSceneRequest
I want to update coordinate of the lookaround instance object. But mapkit.js does not have LookAroundSceneRequest class, how am I going to do. In swift, there is MKLookAroundSceneRequest class, you can specify a new coordinate with this class, to get a new LookAroundScene object, then attach new LookAroundScene to the existing lookAround object, But how am I going to do the same with mapkit.js ?? it missing LookAroundSceneRequest class in js

Does anyone know how to achieve this custom MKAnnotation?
I’ve notice that in Maps, some pins contain images and do not have the little triangle at the bottom of it, yet they still animate the same when clicked. How could this be achieved? I believe the name of this annotation is MKMapFeatureAnnotation. I've tried this and it did not give the same result. I'm able to create a custom MKMarkerAnnotationView but it does not animate the same (balloon animation like the MKMapFeatureAnnotation). I was looking forward to create a custom MKMapFeatureAnnotation similar in design which would animate the same. Unfortunately, I cannot create a custom MKMapFeatureAnnotation because everything is privated

Does Showing User's Current Location on the Map Require 'NSLocationWhenInUseUsageDescription'?
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

iBeacon Monitoring in Flutter App: Background Wake-Up from Killed State, Time Limits for BLE, and Handling Multiple Regions/Identifiers
Hello Apple Developer Community, I'm developing a cross-platform app using Flutter and the flutter_beacon library to handle iBeacon detection on iOS. My goal is to wake up the app in the background when it's in a killed/terminated state upon entering/exiting beacon regions, allowing for BLE communication (e.g., ranging or connecting to beacons). I've configured the necessary Info.plist keys for always location access and background location modes, and it works partially for single regions, but I have some specific questions/issues regarding reliability and limitations: Background Execution Time After Wake-Up: When the app is woken in the background by a region monitoring event (enter/exit) from a killed state, approximately how much time (in seconds) does iOS allocate for the app to run before suspending it again? Is this sufficient for performing BLE operations like ranging beacons or establishing a short connection, or are there stricter limits in terminated wake-ups compared to standard background modes? Monitoring Multiple iBeacons with Unique Identifiers: I need to monitor multiple iBeacon devices, each with potentially different UUIDs, majors, and minors. Can I add and monitor up to 20 regions simultaneously, each with a unique string identifier? If multiple beacons (from different regions) enter their respective ranges at around the same time, will the app receive separate callbacks for each region/identifier, or is there coalescing/prioritization that might cause only the last-added identifier to trigger notifications/events? Reliability in Killed State: In a fully killed state (e.g., force-quit via app switcher), does iOS reliably relaunch the app in the background for region monitoring events? Are there any known caveats, such as requiring specific hardware (e.g., iPhone models with certain Bluetooth chips) or iOS versions (targeting iOS 14+), and how does this interact with Flutter's background execution handling via the flutter_beacon library?

Disable userLocationAnnotation bubble
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!

Background execution window after CLBeaconRegion wake from terminated state
Hello, I am using CLLocationManager to monitor multiple CLBeaconRegion instances (up to 20). When the app is terminated by the system (not force-quit) and a region enter event occurs, the app is relaunched in the background. I have two questions: What is the expected execution time window after relaunch before the app is suspended again? Is it supported to start short CoreBluetooth operations (e.g., scanning or connecting briefly) within this window? I understand that force-quitting the app disables background relaunch, so this question applies only to system-terminated apps.

`MKLocalSearchRequest` change in behavior
aka MKLocalSearch.Request in Swift. Today my users reported that our address auto-complete functionality was returning strange results. We narrowed the issue down to pointOfInterestFilter being set. Sample code below: MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc] init]; request.region = self.region; request.naturalLanguageQuery = addressString; request.resultTypes = MKLocalSearchResultTypeAddress; request.pointOfInterestFilter = [MKPointOfInterestFilter filterIncludingAllCategories]; That last line is the problem. When I stopped setting request.pointOfInterestFilter the MKLocalSearch started working as it always had. To further hammer home the point, with request.pointOfInterestFilter unset I set resultTypes to MKLocalSearchCompleterResultTypePointOfInterest (aka .pointOfInterest) and the issue returned. It seems Apple made a change on their backend recently such that pointOfInterestFilter now overrides resultTypes.

Crucially, I never see the blue "Location In Use" pill on the status bar, even though I have showsBackgroundLocationIndicator = true set. Also, distance filter is set to None. Logs for reference (around suspending) locationd: {"msg":"Sending location to client","Client":"[appName]:","desiredAccuracy":"-1.000000"} runningboardd: Invalidating assertion ... from originator \\\[osservice<com.apple.bluetoothd>:...\\\] runningboardd: Removed last relative-start-date-defining assertion for process app<[appName]...> runningboardd: Calculated state ... running-suspended runningboardd: Suspending task locationd: Client [appName]: disconnected bluetoothd: State of application "[appName]" is now "suspended" Questions Why does invalidating the Bluetooth assertion cause an immediate suspend even though I called startUpdatingLocation() and am receiving updates? Does the missing blue location pill imply that the OS never fully "accepted" the location session? Is there a specific "handshake" required to transition from a BLE wake-up to a long-running location session? I'm wondering if I need to use a background task identifier to bridge the gap between the BLE wake and the location manager taking over. More context: Digging deeper in the comments, I just noticed the following patterns when the application is not suspended vs when it is recently suspended and got awaken by a BLE event. Not suspended: 303948:Jan 23 20:59:35.640118 locationd[6491] <Debug>: {"msg":"Client is setting ContinuousBackgroundLocationRequested", "Client":"[appName]:", "ContinuousBackgroundLocationRequested":1} 303949:Jan 23 20:59:35.640155 locationd[6491] <Debug>: {"msg":"Allowing process assertion due to foreground-ish status", "ClientKeyPath":"[appName]:"} Recently suspended and awaken by BLE: 564296:Jan 23 21:00:23.179125 locationd[6491] <Debug>: {"msg":"Client is setting ContinuousBackgroundLocationRequested", "Client":"[appName]:", "ContinuousBackgroundLocationRequested":1} 564298:Jan 23 21:00:23.179195 locationd[6491] <Notice>: {"msg":"#Warning Denying process assertion", "ClientKeyPath":"[appName]:"} The assertion fails for the second case and that's why the app could not persist. Most importantly, following the logs in the second case, I see the following: locationd[6491] <Notice>: {"msg":"computing freshAuthorizationContext", "Client":"[appName]:", "ClientDictionary":"{\n AlwaysServiceSession = 0;\n I suspect that the flag AlwaysServiceSession being 0 has to do with process assertion being denied for location.

why mapkit js does not have LookAroundSceneRequest
I want to update coordinate of the lookaround instance object. But mapkit.js does not have LookAroundSceneRequest class, how am I going to do. In swift, there is MKLookAroundSceneRequest class, you can specify a new coordinate with this class, to get a new LookAroundScene object, then attach new LookAroundScene to the existing lookAround object, But how am I going to do the same with mapkit.js ?? it missing LookAroundSceneRequest class in js

Does anyone know how to achieve this custom MKAnnotation?
I’ve notice that in Maps, some pins contain images and do not have the little triangle at the bottom of it, yet they still animate the same when clicked. How could this be achieved? I believe the name of this annotation is MKMapFeatureAnnotation. I've tried this and it did not give the same result. I'm able to create a custom MKMarkerAnnotationView but it does not animate the same (balloon animation like the MKMapFeatureAnnotation). I was looking forward to create a custom MKMapFeatureAnnotation similar in design which would animate the same. Unfortunately, I cannot create a custom MKMapFeatureAnnotation because everything is privated

Does Showing User's Current Location on the Map Require 'NSLocationWhenInUseUsageDescription'?
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

iBeacon Monitoring in Flutter App: Background Wake-Up from Killed State, Time Limits for BLE, and Handling Multiple Regions/Identifiers
Hello Apple Developer Community, I'm developing a cross-platform app using Flutter and the flutter_beacon library to handle iBeacon detection on iOS. My goal is to wake up the app in the background when it's in a killed/terminated state upon entering/exiting beacon regions, allowing for BLE communication (e.g., ranging or connecting to beacons). I've configured the necessary Info.plist keys for always location access and background location modes, and it works partially for single regions, but I have some specific questions/issues regarding reliability and limitations: Background Execution Time After Wake-Up: When the app is woken in the background by a region monitoring event (enter/exit) from a killed state, approximately how much time (in seconds) does iOS allocate for the app to run before suspending it again? Is this sufficient for performing BLE operations like ranging beacons or establishing a short connection, or are there stricter limits in terminated wake-ups compared to standard background modes? Monitoring Multiple iBeacons with Unique Identifiers: I need to monitor multiple iBeacon devices, each with potentially different UUIDs, majors, and minors. Can I add and monitor up to 20 regions simultaneously, each with a unique string identifier? If multiple beacons (from different regions) enter their respective ranges at around the same time, will the app receive separate callbacks for each region/identifier, or is there coalescing/prioritization that might cause only the last-added identifier to trigger notifications/events? Reliability in Killed State: In a fully killed state (e.g., force-quit via app switcher), does iOS reliably relaunch the app in the background for region monitoring events? Are there any known caveats, such as requiring specific hardware (e.g., iPhone models with certain Bluetooth chips) or iOS versions (targeting iOS 14+), and how does this interact with Flutter's background execution handling via the flutter_beacon library?

Disable userLocationAnnotation bubble
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!

Background execution window after CLBeaconRegion wake from terminated state
Hello, I am using CLLocationManager to monitor multiple CLBeaconRegion instances (up to 20). When the app is terminated by the system (not force-quit) and a region enter event occurs, the app is relaunched in the background. I have two questions: What is the expected execution time window after relaunch before the app is suspended again? Is it supported to start short CoreBluetooth operations (e.g., scanning or connecting briefly) within this window? I understand that force-quitting the app disables background relaunch, so this question applies only to system-terminated apps.

`MKLocalSearchRequest` change in behavior
aka MKLocalSearch.Request in Swift. Today my users reported that our address auto-complete functionality was returning strange results. We narrowed the issue down to pointOfInterestFilter being set. Sample code below: MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc] init]; request.region = self.region; request.naturalLanguageQuery = addressString; request.resultTypes = MKLocalSearchResultTypeAddress; request.pointOfInterestFilter = [MKPointOfInterestFilter filterIncludingAllCategories]; That last line is the problem. When I stopped setting request.pointOfInterestFilter the MKLocalSearch started working as it always had. To further hammer home the point, with request.pointOfInterestFilter unset I set resultTypes to MKLocalSearchCompleterResultTypePointOfInterest (aka .pointOfInterest) and the issue returned. It seems Apple made a change on their backend recently such that pointOfInterestFilter now overrides resultTypes.
