Standalone watchOS not displaying location authorisation dialog
This is a standalone SwiftUI app w/ watchOS 11. To make things simple, I'm using the new concurrent API, like that: for try await update in CLLocationUpdate.liveUpdates() { … } watchOS is supposed to show the auth dialog, but it doesn't show up, even though update.authorizationRequestInProgress is true. What could be the reason? (Note that I also tried with the procedural old CLLocationManager API, it doesn't work that way as well)

CLLocationUpdate.liveUpdates does not work after recovery from termination with insufficientlyInUse option
In iOS 18, we use CLLocationUpdate.liveUpdates to resume location updates after the app has been terminated. While the app successfully relaunches and I attempt to restart CLLocationUpdate.liveUpdates, the updates frequently come with the insufficientlyInUse flag set to true. At the same time, the locationUnavailable flag is false, but the location value remains nil. Could you clarify what the insufficientlyInUse option indicates and why the location updates are not returning valid data?

MKLocalSearch for cities not returning location identities
Hi fellow developers, I'm encountering an issue when using MKLocalSearch to search for cities. Here's my setup: I'm using MKLocalSearch with an MKLocalSearch.Request object. I've set the resultTypes to .address to focus on address results. The problem: When I receive the search response, it includes the locations as expected. However, these locations don't have an identity or alternative identities. Questions: Is this the expected behavior when searching for cities? Without an identity, how can I uniquely identify and store these city results in my database? Would it be appropriate to store the city name, country, and coordinates instead? Thanks in advance!

CLLocationManager didUpdateLocations called in an infinite loop on macOS Sequoia, despite no startUpdatingLocation called
In my app, I need a one-time location update, which I do with CLLocationManager’s requestLocation(). On iOS, it works fine, but on macOS Sequoia, the CLLocationManagerDelegate’s didUpdateLocations function is called indefinitely in the loop, until I call stopUpdatingLocation() on a manager. This should not be necessary unless I was calling startUpdatingLocation (which I am not), and seems like a newly introduced bug in Sequoia (or Xcode 16). So, just a heads-up to everyone, it's necessary to call stopUpdatingLocation() after obtaining the location (or on error).

How to find coordinates for Map Overlay placement
Hello everyone - I created a navigation app that uses a map overlay for finite spaces such as a zoo. I get these overlays created by a designer in .PNG - the designer creates the overlays and then puts a square or rectangle box around the overlay because it needs to be placed in 9 pieces making it easier to render when user zooms in/out... I used to have my Swift devs place the overlay using the correct coordinates that were given by a single person, but we never found out exactly how they did it - and now I can no longer contact the dev. Can anyone help me by telling me how I can get the coordinates (I am thinking that any opposite vertices would do - and maybe the center point?). I also have a few other questions: a. Is .SVG best to use for map overlays? b. Should we continue to chop into 9 pieces for faster rendering or is there a better way to do this in MapKit (we have been doing this for 4 years, maybe there is a better way) I would be so thankful for any help. Best, Michael

Ellipsoidal Altitude is always zero
I am trying to retrieve the ellipsoidal altitude from a CLLocation but it seems like an invalid value is always returned, no matter the vertical accuracy (which according to the documentation should just be > 0) I first encountered this problem while developing a tool to retrieve workouts from healthkit, but i tried this code in a playground and i still get zero. import CoreLocation var location = CLLocation(coordinate: CLLocationCoordinate2D(latitude: 46.071067, longitude: 13.234579), altitude: 113, horizontalAccuracy: CLLocationAccuracy(floatLiteral: 1.0), verticalAccuracy: CLLocationAccuracy(floatLiteral: 1.0), timestamp: Date()) print(location.ellipsoidalAltitude) Am I doing something wrong or is this a bug?

Prevent pausing location updates on background when stationary?
Hello, I'm trying to receive location updates on background mode but it only lasts about 10 minutes then it stops when API detected the "isStationary" is true. Is there any way to continue receiving updates even when the device is stationary? Btw app is not terminated by the user. I'm using CLLocationUpdate.liveUpdates(.otherNavigation) API. CLBackgroundActivitySession is created before calling the liveUpdates. CLLocationManager: let manager: CLLocationManager = { let manager = CLLocationManager() manager.distanceFilter = kCLDistanceFilterNone manager.desiredAccuracy = kCLLocationAccuracyThreeKilometers manager.pausesLocationUpdatesAutomatically = false manager.activityType = .other manager.showsBackgroundLocationIndicator = true manager.allowsBackgroundLocationUpdates = true return manager }() Thank you!

Image using MKLookAroundSnapshotter with Updated Scene
I'm trying to create a UIImage from a MKLookAroundScene, after the user has moved the scene, by looking (and moving) around. Is this possible? When I use MKLookAroundSnapshotter with the modified scene, I always get an image of the original (starting) scene. STEPS TO REPRODUCE Create a scene using MKLookAroundSceneRequest with coordinates. Use LookAroundPreview with a binding to MKLookAroundScene to get changes to the scene (based on looking around). User begins LookAround, moving the scene location and view. User ends LookAround The preview displays the updated scene properly. The scene's cameraFrameOverride values reflect the pitch, roll, yaw, and location changes. Pass the updated scene to MKLookAroundSnapshotter to get an image. Display the Image. The Image is the original scene (not what is displayed in the preview).

Using CPVoiceControlTemplate in my CarPlay app to capture voice
I have a CarPlay navigation app and I would like to allow the user to speak an address and have our app search at that location. In the Waze app, it provides a button to tap, then it brings up a CPVoiceControlTemplate and you can give it directions or a location and it will then show you search results including the text you spoke as the title. I assume that app would have the same limitations as I do, so I am wondering how another app might do this? It was suggested that I use an App Intent with suggested phrases and then a Shortcut could perform the action. Is there documentation on this somewhere or am I going in the wrong direction here? Obviously Waze is doing what I am wanting so there must be a way. Can anyone point me in the right direction?

Add the capability of "Access Wi-Fi information" and show the location access indicator
We met a question recently in our project, we try to achieve the SSID,so we need to do the following two things : request location permission add the capability of "Access Wi-Fi information" then the app always shows the location access indicator. , In the app privacy report , we see the app always request the location. But when I try to remove "Access Wi-Fi information" the capability , the scenario disappear. Any ideas can explain this ? How can I remove the location access indicator with out remove the "Access Wi-Fi information" . I indeed need this. Thanks in advance.

App Clips Advanced Experiences not showing up in Apple Maps and Siri Suggestions
Hello everyone, I’m experiencing an issue with App Clips Advanced Experiences and Apple Maps/Siri Suggestions. We have already contacted Apple Support before, but they are investigating the cause of this issue and it has not been resolved til date. The App Clip is bundled with the main app and has been already available on the App Store for several months. The business running the app has several physical shops and wants to offer the App Clip to show up in Apple Maps and Siri Suggestions at each location. The App Clip is correctly exposed in the AASA file, and it's also validated correctly by the AASA APIs available at https://app-site-association.cdn-apple.com/a/v1. { "applinks": { "apps": [], "details": [ { "appID": "TEAMID.bundleid", "paths": [] } ] }, "appclips": { "apps": [ "TEAMID.bundleid.Clip" ] } } (with TEAMID and bundleid being the team and bundle identifiers of the app) The App Clip is displayed correctly when loading the website and when scanning a QR code or App Clip code, but doesn't appear in the Maps app or in Siri suggestions. We have set up the App Clip Advanced Experiences on the App Store Connect page of the app, and each URL has been linked to a physical shop. All URLs are in the "Received" state, so they should appear correctly on Maps. Unfortunately, I don't see any "Order" button in Apple Maps at any location card. We tried with both iOS 17 and 16. According to feedbacks from people in the shops, they don't see the app suggested in the Siri Suggestions. I have just submitted a Custom Action Link on Apple Business Connect for one of the shops, but without success: the App Clip doesn't appear. Any idea why is this happening?

What is the reason for the CLLocationmanager.locationServicesEnabled() "invoked on main thread" warning?
I am looking into a piece of old code where the mentioned method is called. + (bool)isLocationServicesEnabled { return [CLLocationManager locationServicesEnabled]; } I'm getting the classic "This method can cause UI unresponsiveness if invoked on the main thread. Instead, consider waiting for the -locationManagerDidChangeAuthorization: callback and checking authorizationStatus first." I have 2 questions: What is that error about, really? The locationServicesEnabled() has nothing to do with authorisation, it's just about the "location services" settings global on-off switch? (the authorisation check is .authorizationStatus) I don't understand why that call is such a big issue? It's just a setting? Why would that be so costly? Thankful for pointers! Have a good one

How can I get something similar to launchOptions[UIApplication.LaunchOptionsKey.location] in SceneDelegate for iOS 13+ apps
I'm making an app for iOS 13+ devices. My project has both app delegate and scene delegate files. I'm using core location for significant location changes. I was able to detect significant location changes and system waking up my app in simulator using SignificantlyChanged app’s scheme. But when the launch options dictionary has 0 elements and the value for the key UIApplication.LaunchOptionsKey.location is always nil. Here is my AppDelegate.swift where the system will launch the app in background state when a significant location change is detected and execute the location fetch code. And location manager class. I want to know if the app is launched my the system or if it is launched by the user so I want to check if UIApplication.LaunchOptionsKey.location key has a value. But it is always nil and there is no alternative to it in SceneDelegate. When and how can I find a solution to this long due issue. import CoreLocation @main class AppDelegate: UIResponder, UIApplicationDelegate { func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { // Override point for customization after application launch. if launchOptions != nil{ if launchOptions![UIApplication.LaunchOptionsKey.location] != nil{ print("Called from background location fetch") } } LocationService.shared.askForPermission() LocationService.shared.delegate = self return true } // MARK: UISceneSession Lifecycle func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration { // Called when a new scene session is being created. // Use this method to select a configuration to create the new scene with. return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role) } func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) { // Called when the user discards a scene session. // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions. // Use this method to release any resources that were specific to the discarded scenes, as they will not return. } } extension AppDelegate: LocationMangerDelegate{ func didFetchLocation(coordinate: CLLocationCoordinate2D) { print(coordinate) } func didFailToFetchLocation(error: Error?, message: String) { print(message) } }``` import Foundation import CoreLocation protocol LocationMangerDelegate: AnyObject{ func didFetchLocation(coordinate: CLLocationCoordinate2D) func didFailToFetchLocation(error: Error?,message: String) } class LocationService: NSObject{ private override init() { } weak var delegate: LocationMangerDelegate? static var shared = LocationService() lazy var locationManager: CLLocationManager = { var manager = CLLocationManager() manager.desiredAccuracy = kCLLocationAccuracyBest manager.allowsBackgroundLocationUpdates = true manager.pausesLocationUpdatesAutomatically = false manager.delegate = self return manager }() func askForPermission(){ print("INSIDE") locationManager.requestWhenInUseAuthorization() } func startLocationUpdates(){ self.locationManager.startUpdatingLocation() } func stopLocationUpdates(){ self.locationManager.stopUpdatingLocation() } } extension LocationService: CLLocationManagerDelegate{ func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) { let status = manager.authorizationStatus switch status { case .notDetermined: self.askForPermission() case .restricted: self.delegate?.didFailToFetchLocation(error: nil, message: "Location permission is restricted by the user") case .denied: self.delegate?.didFailToFetchLocation(error: nil, message: "Location permission is denied by the user") case .authorizedWhenInUse: self.locationManager.requestAlwaysAuthorization() case .authorizedAlways: self.locationManager.startMonitoringSignificantLocationChanges() @unknown default: break } } func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { if let location = locations.first{ print(location) self.delegate?.didFetchLocation(coordinate: location.coordinate) self.stopLocationUpdates() } } func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) { print(error) self.delegate?.didFailToFetchLocation(error: error, message: error.localizedDescription) } }

Did WeatherKit minutely precipitation intentionally change units?
I've noticed in the past few weeks that the minutely precipitation values reported by WeatherKit are much bigger than they were before. Specifically I'm referring to WeatherKit.MinuteWeather.precipitationIntensity. In my app, I convert to mm per hour: let mmPerHour = $0.precipitationIntensity.converted(to: UnitSpeed.kilometersPerHour).value * 1e6 This has worked perfectly since WeatherKit came out, but now when I look at rainy locations and compare with the built-in Apple Weather app on my phone, it seems that the new values are about 3x what they should be. I have checked this in multiple locations across the USA. My intuition says this is an inches/cm conversion issue (2.54x). Is this an intentional change in WeatherKit that requires me to update my app, or is this a bug on Apple's end??
