CarPlay
Non of my maps are working like they supposed to be. Before the update everything was working fine in CarPlay but for some reason after updating I can’t click on anything on the car screen.

MKLocalSearch request limit
I'm a bit unsure about whether there’s a limit on the number of requests when using MKLocalSearch from MapKit. For example, if I have a large user base and need to make 200 requests per minute at peak times, will MapKit be able to handle this? Will the user be throttled after a number of requests? If there is a limit, is it based on the user or developer account? Additionally, if there is a limit, is it per day? Can you clarify? Just to give you an idea, here is an example of the request we make: let searchRequest = MKLocalSearch.Request() searchRequest.naturalLanguageQuery = myQueryStringHere localSearch?.cancel() // cancel the previous call if it exists localSearch = MKLocalSearch(request: searchRequest) localSearch?.start { (response, error) in guard error == nil else { completion(.failure(.myError)) return } let mapSearchLocations = response?.mapItems completion(.success(mapSearchLocations)) } } I appreciate your help in advance.

MKLocalSearch request limit
Hello, It’s unclear to me if there is a limit of requests when using MKLocalSearch from MapKit. Let’s say I have a very large user base and will use 1000 requests per minute at peak times. Will MapKit support this? But if there is a limit, is it by user or by developer account? Also, if there is a limit, is it per day? Here is an example of the request we use. let searchRequest = MKLocalSearch.Request() searchRequest.naturalLanguageQuery = myQueryStringHere localSearch?.cancel() // cancel the previous call if it exists localSearch = MKLocalSearch(request: searchRequest) localSearch?.start { (response, error) in guard error == nil else { completion(.failure(.myError)) return } let mapSearchLocations = response?.mapItems completion(.success(mapSearchLocations)) } }

requestWhenInUseAuthorization Crash iOS 18 Beta 4
When I call requestWhenInUseAuthorization in state kCLAuthorizationStatusNotDetermined on iOS 18 Beta 4 in the simulator, all my apps just terminate without any error message in the Xcode console (black screen with an activity indicator for a second or two and then it goes back to the springboard). I do have the NSLocationWhenInUseUsageDescription set in my Info.plist file. When running the exact same apps in Xcode 16.0 beta 4 (16A5211f) but with a iOS 17 simulator attached, it is working as expected by showing the location authorization dialog. Is this a known issue or am I missing something?

iPadOS Public Beta - Map Rendering
Been running the public beta for a few days. One significant anomaly. I run an app called Garmin Pilot. It is an aviation Electronic Flight Bag. Since loading the beta, the map rendering in the app has run into a problem. The two side-by-side photos are the same scene on the map except for the zoom level. At 10NM and above, it's fine. The US Sectional chart is viewable. Drop down to 5NM and the chart disappears. It is the same with other charts in the app. I am a user of multiple EFB apps and Pilot seems the only one affected. And yes, I reported it to the app developers as well.

Expected behavior of CLServiceSessions(.always) after device restart?
Hi! I was wondering what the expected behavior of CLServiceSession(authorization: .always) after a device restart was? What I am observing right now is that, after a device restart, location access from the background is denied until the app enters the foreground for the first time (CLServiceSession.Diagnostic says insufficientlyInUse: true; CLLocationUpdate additionally says serviceSessionRequired: true). Is this the expected behavior? If it is, then this seems like a somewhat suboptimal user experience to me, at least for my use case - the user's intention regarding the background location access won't have changed just because the device was rebooted. (In case this is relevant, my use case is transmitting the current location to connected Bluetooth devices, e.g. digital cameras. As such my app is setting UIBackgroundModes of ["bluetooth-central”]).

MapKit .standard doesn't allow for globe view when zoomed out
Hi, I'm writing because I've been trying to set the .standard map style to render as a globe on an iPhone 15 running iOS 17 when zoomed out similar to how it works in Apple Maps but can't find any resources on how to make that happen as every time it appears as a flat 2D map, much unlike the .hybrid and .satellite types. I found another thread on this forum a year ago where someone said .standard was bugged and couldn't become a globe, but I'm honestly quite surprised this issue hasn't been brought up more often.

Guideline 5.1.2 - Legal - Privacy - Data Use and Sharing
The app privacy information provided in App Store Connect indicates the app collects data in order to track the user, including Precise Location. However, the app does not use App Tracking Transparency to request the user's permission before tracking their activity. Apps need to receive the user’s permission through the AppTrackingTransparency framework before collecting data used to track them. This requirement protects the privacy of users. ---How do I fix this problem? I've submitted my app and in return they provided a screenshot of it clearly asking for permission before the app even loads the map in the background. Even though in the screenshot it's asking them for permission they are telling me it's not prompting the user before it starts tracking. I'm lost, help.

Location interval on the iOS platform, with Flutter's Geolocator
Hey guys. I'm building a cross-platform app using Flutter, which uses the Geolocator package to see how far the user has travelled from their starting point, aviation related. I do allow the user to select their own distance filter value from a set of pre-defined options, which could be as low as a metre, since the app is designed for use over relatively small distances, from say 200m to 1km. Therefore, having a large distance filter value wouldn't make much sense. However, the issue I am having is that with iOS, I can't seem to control the actual sample rate of the user's location. From what I gather, iOS measures the user's location approximately once every second, give or take a bit, but that value cannot be changed. That's quite different to Android, where I can specify this measurement interval to be whatever I want it to be. This lack of ability to control the measurement interval tends to cause quite a lag. When someone first starts to move, they aren't travelling fast enough to cause a noticeable lag. However, when someone's speed picks up, they could be travelling at around 70mph/32m/s (ish). If you're only measuring the user's location once every second, then it's likely they will have travelled over 30m before the next location update, which means the lag distance could potentially be huge relative to the maximum distance they will measure using the app. I do fully appreciate that this is native functionality to iOS but my question really is, is there perhaps a way around this? Is there any way to increase the frequency with which the user's location is retrieved, so that I can reduce this lag? If there isn't, that's no problem at all. I just thought I would ask the question, incase someone has come across this before and found a solution that works. These are the Apple-related settings that I have been able to control with Flutter, for the Geolocator package. Thank you in advance! locationSettings = AppleSettings( accuracy: LocationAccuracy.bestForNavigation, activityType: ActivityType.otherNavigation, distanceFilter: distanceFilterValue, pauseLocationUpdatesAutomatically: false, showBackgroundLocationIndicator: false, );

Getting "locationUnknown" as error code in Core Location delegation method didFailWithError for iOS v17.5 and v17.5.1
We have been observing a major spike in Core Location delegation method didFailWithError for iOS v17.5 and v17.5.1. Sharing the implementation of the code at our end - func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) { if let clError = error as? CLError { switch clError.code { case .locationUnknown: print("Location unknown") case .denied: print("Access denied") case .network: print("Network error") default: print("Other error: (clError.code)") } } else { print("Other error: (error.localizedDescription)") } } We are observing error responses with error code 0: locationUnknown in iOS 17.5 and above. Is anyone else facing the same issue? Not able to debug this at our end.

Siri can directly launch Map App for navigation
DESCRIPTION OF PROBLEM We discovered that Siri can directly launch Amap and Tencent Maps for navigation. Our app also wants to integrate this feature. After our research, we found that AppIntents cannot accomplish this functionality. Because the parameters of AppIntents are limited. How can we achieve this? Do we need to apply for certain permissions from Apple? STEPS TO REPRODUCE awake siri say "使用高德地图打车去南京南站"
