Weather App
I keep getting severe weather warnings in CA but I’m in NY. I have checked my locations and I have no CA weather requests selected. I clicked on the alert and it said it was from weatherkit. How do I make these CA go away for good? Thanks!

GPS Icon Appears on App Launch Despite No CLLocationManager Usage – Need Help Tracing Cause
Hello everyone, I’m facing an issue with my iOS app where the GPS/location services icon appears in the status bar immediately when the app is launched, even though I’m not intentionally accessing location services at that point. Issue Summary: • GPS Icon Activation: When I launch my app, the GPS icon turns on. It turns off when the app is minimized or closed. • No Intentional Location Usage at Launch: I have ensured that no instances of CLLocationManager are created when the app is launched. What I’ve Tried So Far: 1. Checked Controllers and Related Classes: • Reviewed all the code for the controllers that are active at launch. • Verified that none of these controllers create instances of CLLocationManager or call location-related methods. 2. Commented Out startUpdatingLocation: • Commented out all calls to startUpdatingLocation throughout the entire project. 3. Ensured No CLLocationManager Instances at Launch: • Searched for any code that might instantiate CLLocationManager during app launch. • Confirmed that no such instances are being created. 4. Commented Out Google Maps SDK Configuration: • In AppDelegate, commented out the Google Maps SDK configuration, so it’s not initialized with the API key. • No map views (GMSMapView, MKMapView) are initialized or used when the app is launched. 5. Tested Location Permissions: • When I change the location permission for the app to “Never” in the Settings app, the GPS icon does not appear upon app launch. • This suggests that the app is accessing location services when it has permission, even though I haven’t explicitly requested it at launch. Objective: • Control GPS Activation: I want to ensure that the GPS does not turn on when the app is launched. I intend to activate location services only when needed later in the app. Request for Assistance: I’m seeking guidance on the following: 1. Debugging Techniques: • How can I trace the code that’s causing the GPS to turn on at app launch? • Are there tools or methods to identify hidden or indirect calls to location services? 2. Forcing Location Services Off at Launch: • Is there a way to programmatically prevent location services from activating during app launch? • Can I defer any implicit location service initialization until I explicitly enable it? 3. Potential Hidden Triggers: • Are there known scenarios where location services could be activated without direct use of CLLocationManager? • Could frameworks like Google Maps SDK trigger location services even if not fully initialized? 4. Additional Suggestions: • Any other insights or suggestions to prevent the GPS icon from appearing on app launch. Additional Information: • Third-Party Frameworks: • I have not removed third-party frameworks yet, as I wanted to check other possibilities first. • Open to the idea that a third-party framework might be causing this, but need guidance on how to confirm. • Code Availability: • I’m happy to provide specific code snippets if that would help diagnose the issue. Environment: • Xcode Version: Xcode 15.4, Xcode 16.0 • iOS Deployment Target: iOS 15.0 • Devices Tested: iPhone SE 2nd and 3rd gen, iPhone 15, iPhone 15 pro, iPhone 11 • Programming Language: Swift What I’m Looking For: • Assistance in tracing the cause of the GPS activation on app launch. • Suggestions on how to prevent location services from starting until explicitly needed. • Insights into any hidden triggers or indirect usages that might cause this behavior. Thank you for your time and assistance. Any help to resolve this issue would be greatly appreciated.

Iphone is deleting my messages automatically
I have checked the setting and it is and has always been set to forever when it comes to settings-messages-message history. Yet since I upgraded to ios 18.1, my messages have started to delete by themselves every other day or so. In the last week, I have had to go into the recently deleted and recovered the messages at least 3-4 times. It does not delete all my messages just random messages from whom I have messaged recently. I have message that have been there for at least 6 years and those are not deleting. Please help before I lose some valuable messages.

MKLocalSearch for cities - How to uniquely identify results?
I'm using MKLocalSearch with resultTypes set to .address to search for cities. The search results don't include an ID for each city, which I need for database storage (which from my understanding is the only thing we can store). If I can't store the city name, country, and coordinates in my database, and I'm not allowed to use third-party data (like a pre-made list of cities with coordinates), what are my options for uniquely identifying and storing these city results? Any suggestions would be greatly appreciated.

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.
