MapKit JS authorization token invalid for Chinese network
Hello 👋🏼, We are using MapKit JS to display maps on our application working on two domains .com and .cn. Everything is working for all ours users in the world except for users using Chinese local network. After investigation, there is an error display in the browser console: [MapKit] Initialization failed because the authorization token is invalid. As the tokens are used as they are for the rest of the world, we know that they are valid... 😕 Problem appears on all browsers: Current versions of MapKit JS mapkit-typescript @ 5.18.2 https://cdn.apple-mapkit.com/mk/5.49.x/mapkit.js Do you have any tips, suggestions to help us 🙏 ? Aurélien.

Background location stops with (kCLErrorDomain error 1.) but permission was granted
We are currently experiencing a very interesting issue when accessing the location in the background with CLLocationManager. The user has given our app the "whenInUse" permission for locations and in most cases the app provides location updates even when it's in the background. However, when we started to use other navigation apps in the foreground we saw that the func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) method was called with (kCLErrorDomain error 1.). The user hasn't changed the location permission and we saw that locations were delivered once the user opened the app again. I don't see anything in the documentation explaining this issue, but I chatted with other developers that confirm that specific behavior. Am I missing something here?

UIKit mapView color annotations
I have tried to make colored annotations in mapView (shown in the commented sections) but they always appear in black.

Request of CarPlay Navigation Entitlement when having the Driving Task one
I have the CarPlay Entitlement "Driving Task" and two of my apps use it. Now, in both apps, I have implemented Navigation. I requested the Navigation CarPlay Entitlement when the feature was mature and builds were available in Test Flight, since I wanted to release the new versions of the apps with navigation available both on the iPhone and in CarPlay. I got no answer to my request, so I decided to release the apps with only navigation in the iPhone and the Driving Task functionality in CarPlay, thinking that maybe being live with navigation in the App Store was a requirement. I have asked permission again, and so far, the request is being ignored again. What are the requirements to get the Navigation CarPlay Entitlement? If the app is approved for navigation, is there something else the app must do to get the entitlement? Requirements for CarPlay Entitlements seem quite obscure, are they listed anywhere? Is there a technical problem to move from an existing CarPlay Entitlement to another? Can that be the reason the entitlement has not been granted? Some of my competitors have the CarPlay Navigation entitlement. My use case is the same (in a better app in my opinion, of course). But I am only getting bad reviews because "the app does not include the map in CarPlay" after the big investment in implementing navigation in the apps. Any help or insight would be appreciated.

Clarification needed regarding requirements for geofencing
In my app, I am using geofencing to perform an action when the user enter or leaves a specified location. The geofencing (CLMonitor) is active permanently, and should work across multiple app sessions or after the device is restarted. It should also work after the app was minimized or terminated. This worked perfectly with iOS 17 and prior, but with iOS 18, things changed. As soon as iOS 18 dropped, users were informing me that the app does no longer perform the entry/exit action reliably (without me making any changes to the app). Most of the times, events are missed entirely. Sometimes, after the user opens or resumes the app, duplicate events are delivered and/or events with the current time instead of the correct time of entry/exit. I am making sure that the app has the "Always" location permission before geofencing is enabled The gefocence radius is between 20 and 500m, but even with the max. radius specified, the geofencing is unreliable For the same user and geofence, the entry/exit event is delivered occasionally, but not always I am currently not using CLLocationManager.allowsBackgroundLocationUpdates (even though it's documented as "Apps that receive location updates when running in the background must include the UIBackgroundModes key (with the location value) in their app’s Info.plist file") because it wasn't necessary on iOS 17 and in my tests, using it didn't yield any improvements In my search for what could have caused this change, I found this WWDC video about location authorization: . It appears that with iOS 18, it is now required to have an active CLServiceSession to ensure that location updates are delivered to my app. Even though the video is long (and I've watched it multiple times), some things are still unclear. For example, the docs state: If your app actively receives and processes location updates and terminates, it should restart those APIs upon launch in order to continue receiving updates. Also, in the video it is stated that: ... So your job, ..., is to make sure that your process launch logic knows what features it has been tasked with pursuing, and re-takes session objects... But on the other hand it's also said that: you can only start holding one (a CLServiceSession) when your app is in the foreground and also ... CLMonitor.events won’t yield results when it is not in use, unless a session which was started in the foreground, .... To summarize my questions, for the geofencing to work as described above: when exactly do I need to create a CLServiceSession if the app is launched into the backgorund? Immediately in the applicationDidFinishLaunching method, even though the app is still in the background (applicationState is background)? Or later on, when the app is opened again by the user, e.g. in applicationDidBecomeActive (and applicationState is active)? do I need to specify the background mode capability as noted in the Handling location updates in the background article? do I need to create a CLBackgroundActivitySession as noted in the Handling location updates in the background article? does it matter, which of the four initializer methods I am using to create the CLServiceSession (with CLServiceSessionAuthorizationRequirementAlways)? does it matter if I specify NSLocationRequireExplicitServiceSession in the Info.plist or not when I already do ensure that the app has the "Always" location permission when the feature is being enabled Does a CLServiceSession last indefinitely and should it only be invalidated once the user disables the feature?

Unable to use altitude for our use case (NYC MTA)
We’re building a new subway/bus app at the MTA. Our system includes roughly 300 underground stations, around 150 elevated stations (i.e., above street level), and about 5 at-grade stations (i.e., at street level). We serve roughly 5 million riders a day. We’re diving deep into Core Location on iOS and have found that the altitude values returned from two fields we’re testing aren’t accurate enough for our use case: CLLocation.altitude CMAbsoluteAltitudeData.altitude We need to reliably distinguish whether a user is: At street level On an elevated platform (see attached picture) On any platform in an underground station — most have a single platform level, but some, like 59 St (see attached), have multiple platforms at different elevations. These levels typically differ by at least 15 feet, which should in theory be well within the precision range of a properly calibrated barometric pressure sensor. However, the absolute altitude values we’re seeing from these APIs are often inaccurate and inconsistent — not only compared to ground truth, but also across devices. For example, holding two phones side-by-side frequently yields altitude readings that differ by more than 15 feet. That level of variation makes the data unreliable for our needs. Please see the below photos for more context. URLs.md

Core Location reports incorrect location update especially with underground travel
Description of the Bug: Core Location intermittently reports inaccurate location updates, albeit with a high accuracy value. This problem occurs almost exclusively while travelling in metros underground affecting the ability to rely on the framework effectively. Steps to Reproduce: The user starts travelling on ground level at point A The user continues travelling and, after some time, is now underground at point B. A stationary beacon scanned at point B confirms this. Core Location is observed to deliver a location update with a high-accuracy value but with the coordinates around point A when the user is actually around point B. Expected Behaviour: Accurate locations should be delivered at all times. In other words, Core Location should not report location updates with high accuracy when its certainty is low.

Zspeedaccuracy question
Hello everyone, I'm doing some work on validating some data to do with the zpseed functionality around corelocations, i've read up on the speedaccuracy field but the wording doesn't make sense to me. It says if its a positive number it is plus or minus the value in the zspeed column so would this be for example zspeed of 35 mps with an accuracy of 3 mps would it be 32 mps 38 mps or is it a range? so would it be anywhere between 32-38 mps. Or is it just plus or minus the 3mps and if this is the case how would it be worked out if its plus or minus when all the numbers will be a positive numbers as any negative numbers are deemed inaccurate ?

GPS HDOP
I have a marine navigation app which displays GPS quality information when receiving NMEA message from an external GPS. These include the number of satellites and Horizontal Dilution of Precision (HDOP). As far as I can see, the only additional information available through location services (for devices with built in GPS) is horizontal and vertical accuracy. Am I missing anything? Also does anyone know how horizontal accuracy is derived from HDOP?

MapKitJS Pricing
Hello (: I have a question regarding the current pricing model for Apple Maps APIs, specifically MapKitJS, the Maps Snapshot API, and the Maps Server API. Previously, the documentation and my understanding indicated that the usage limits were defined per day — for example, 250,000 map loads per day for MapKitJS and 25,000 snapshots per day. However, in the Apple Developer Dashboard, I’m now seeing these limits shown on a per-month basis, such as only 25,000 snapshots per-month. This appears to contradict the publicly available information on the official website, which still states daily limits. Has the pricing model officially changed, or is this just a display issue in the dashboard? I need to know this because we're going into release soon, and then we might have thousands of users.

Or later on, when the app is opened again by the user, e.g. in applicationDidBecomeActive (and applicationState is active)? do I need to specify the background mode capability as noted in the Handling location updates in the background article? do I need to create a CLBackgroundActivitySession as noted in the Handling location updates in the background article? does it matter, which of the four initializer methods I am using to create the CLServiceSession (with CLServiceSessionAuthorizationRequirementAlways)? does it matter if I specify NSLocationRequireExplicitServiceSession in the Info.plist or not when I already do ensure that the app has the "Always" location permission when the feature is being enabled Does a CLServiceSession last indefinitely and should it only be invalidated once the user disables the feature?

Not able to create map id
I'm following: https://developer.apple.com/documentation/applemapsserverapi/creating-a-maps-identifier-and-a-private-key#Create-a-Maps-ID to create map id and private key. On step #4 I can't find "Maps IDs checkbox" on the web page, blow is the screen capture which contains all options I have on my page:

Unable to use altitude for our use case (NYC MTA)
We’re building a new subway/bus app at the MTA. Our system includes roughly 300 underground stations, around 150 elevated stations (i.e., above street level), and about 5 at-grade stations (i.e., at street level). We serve roughly 5 million riders a day. We’re diving deep into Core Location on iOS and have found that the altitude values returned from two fields we’re testing aren’t accurate enough for our use case: CLLocation.altitude CMAbsoluteAltitudeData.altitude We need to reliably distinguish whether a user is: At street level On an elevated platform (see attached picture) On any platform in an underground station — most have a single platform level, but some, like 59 St (see attached), have multiple platforms at different elevations. These levels typically differ by at least 15 feet, which should in theory be well within the precision range of a properly calibrated barometric pressure sensor. However, the absolute altitude values we’re seeing from these APIs are often inaccurate and inconsistent — not only compared to ground truth, but also across devices. For example, holding two phones side-by-side frequently yields altitude readings that differ by more than 15 feet. That level of variation makes the data unreliable for our needs. Please see the below photos for more context. URLs.md

Core Location reports incorrect location update especially with underground travel
Description of the Bug: Core Location intermittently reports inaccurate location updates, albeit with a high accuracy value. This problem occurs almost exclusively while travelling in metros underground affecting the ability to rely on the framework effectively. Steps to Reproduce: The user starts travelling on ground level at point A The user continues travelling and, after some time, is now underground at point B. A stationary beacon scanned at point B confirms this. Core Location is observed to deliver a location update with a high-accuracy value but with the coordinates around point A when the user is actually around point B. Expected Behaviour: Accurate locations should be delivered at all times. In other words, Core Location should not report location updates with high accuracy when its certainty is low.

Zspeedaccuracy question
Hello everyone, I'm doing some work on validating some data to do with the zpseed functionality around corelocations, i've read up on the speedaccuracy field but the wording doesn't make sense to me. It says if its a positive number it is plus or minus the value in the zspeed column so would this be for example zspeed of 35 mps with an accuracy of 3 mps would it be 32 mps 38 mps or is it a range? so would it be anywhere between 32-38 mps. Or is it just plus or minus the 3mps and if this is the case how would it be worked out if its plus or minus when all the numbers will be a positive numbers as any negative numbers are deemed inaccurate ?

GPS HDOP
I have a marine navigation app which displays GPS quality information when receiving NMEA message from an external GPS. These include the number of satellites and Horizontal Dilution of Precision (HDOP). As far as I can see, the only additional information available through location services (for devices with built in GPS) is horizontal and vertical accuracy. Am I missing anything? Also does anyone know how horizontal accuracy is derived from HDOP?

MapKitJS Pricing
Hello (: I have a question regarding the current pricing model for Apple Maps APIs, specifically MapKitJS, the Maps Snapshot API, and the Maps Server API. Previously, the documentation and my understanding indicated that the usage limits were defined per day — for example, 250,000 map loads per day for MapKitJS and 25,000 snapshots per day. However, in the Apple Developer Dashboard, I’m now seeing these limits shown on a per-month basis, such as only 25,000 snapshots per-month. This appears to contradict the publicly available information on the official website, which still states daily limits. Has the pricing model officially changed, or is this just a display issue in the dashboard? I need to know this because we're going into release soon, and then we might have thousands of users.
