MapKit JS 401 Not Authorized (details empty) even with multiple token variants
Hi everyone, I’m troubleshooting a persistent MapKit JS auth issue and would appreciate any advice. I have: Active Apple Developer account/team Maps configuration created and linked Active Maps-enabled signing key Domain-restricted token setup I tested multiple JWT variants: with origin without origin (basic example style) with and without exp exact domain and wildcard domain variants I also tested using a minimal/basic MapKit JS integration and still got the same result. Bootstrap request: `curl -s --compressed -D - \ 'https://cdn.apple-mapkit.com/ma/bootstrap?apiVersion=2&mkjsVersion=5.81.60&poi=1' \ -H 'Authorization: Bearer <JWT>' \ -H 'Origin: https://<my-domain>' \ -H 'Referer: https://<my-domain>/...' Result is always:` HTTP 401 {"error":{"message":"Not Authorized","details":[]}} Important detail: mapkit.core.js loads successfully (HTTP 200) failure happens only on bootstrap auth Has anyone seen this exact behavior with empty details and found what was wrong? Any checklist for hidden misconfiguration points (key linkage, token generation method, domain restriction behavior, propagation timing) would help.

Maps tokens suddenly stopped working today and now return 401 everywhere
Hi, Our Apple Maps integration has been working normally for years, but starting today, newly created Maps tokens suddenly became unusable. Tokens created from the Apple Developer backend now return 401 Unauthorized everywhere we test them. We can reproduce this in: our own code Apple’s Try Maps Server API page MapKit JS So this does not appear to be limited to our app code. We also tested through a US network entry point to rule out a mainland China network issue, but the result was the same. At the moment, Maps tokens created in the backend seem to be unusable in all cases on our side. Has anyone else seen this today, or is there any known issue affecting Maps token creation or validation? Thanks.

MapKit JS Look Around not pointing camera towards the lat/lng entered
We are using MapKit JS Look Around and initializing it like this: window.lookAround = new mapkit.LookAround( document.getElementById('container'), new mapkit.Coordinate(listingLocation[1], listingLocation[0]), {openDialog: false}) ; This results in a Look Around scene being displayed correctly but the camera heading is not pointing towards the lat/lng that is passed to initialization. The example lat/lng that we're using is: lat=30.004195, lng=-95.59973 This lat/lng corresponds to the address: 11943 Laurel Meadow Dr, Tomball, TX 77377. The camera is pointing to the other side of the street to house number 11946. If you look for that address in Apple Maps the Look Around points to the correct house. Is there a way to either specify the heading so that Look Around points in the correct heading? Sample link: https://s.hartech.io/zFP2KnsCbsP

Does Nearby Interaction support UWB multicast communication?
Hello, I am currently working with the Nearby Interaction framework on iOS and exploring the capabilities of UWB-based communication. I would like to ask whether Nearby Interaction supports multicast communication over UWB. Specifically, is it possible for one device to interact simultaneously with multiple peer devices using UWB (e.g., broadcasting ranging or spatial information to multiple devices at once), or is the framework strictly limited to one-to-one peer interactions? If multicast is not supported, are there any recommended approaches or best practices for achieving similar functionality using the current APIs? Thank you for your help. Best regards,

How do you get a clickable location when building a subscribable event?
I am trying to provide my clients with subscribable calendar link so they can see their schedules from an App I have. I've got the basics working on building out the various fields for the VEVENT, however no matter what I have tried the LOCATION is always showing up as a text and not a location within Apple Maps that I can have them click on from the event. Any idea what the best way to go about this would be, and feeding the ICS an address, Apple Maps URL, GPS coordinates either in the location, Geo or the X-APPLE-STRUCTURED-LOCATION or combinations haven't been working. I am using/hosting on Google Scripts.

Inquiry regarding regional availability and restrictions of the Apple Find My Network
Hello, I am trying to gather information on the global availability of the Apple Find My Network. Specifically, I would like to know: Which countries currently support this feature? Is it available worldwide, with only a few specific countries/regions facing usage restrictions or complete unavailability? I have already reviewed the public Feature Availability page, but was unable to find any documentation addressing regional restrictions. Any clarification or pointers to relevant documentation would be greatly appreciated. Thank you!

Native Wind Animation Layer for Apple Maps / MapKit
Hey Apple team, I'd love to see a native wind animation layer added to Apple Maps and MapKit. A built-in, system-level wind visualization — similar to the animated weather layers seen in third-party apps — would be an incredibly powerful tool for developers building weather, aviation, marine, outdoor recreation, and navigation apps. Having this baked natively into MapKit would mean smoother performance, better battery efficiency, and a consistent experience across iOS, iPadOS, and macOS — rather than every developer having to reinvent the wheel with custom particle systems or third-party SDKs. Please Apple — this would be a fantastic addition to the Maps ecosystem. 🌬️🗺️

Scene-based Launch Detection
Our app supports UIScene. As a result, launchOptions in application(_:didFinishLaunchingWithOptions:) is always nil. However, the documentation mentions that UIApplication.LaunchOptionsKey.location should be present when the app is launched due to a location event. Given that our app is scene-based: How can we reliably determine whether the app was launched due to a location update, geofence, or significant location change? Is there a recommended pattern or API to detect this scenario in a Scene-based app lifecycle? This information is critical for us to correctly initialize location-related logic on launch. Relevant documentation: https://developer.apple.com/documentation/corelocation/cllocationmanager/startmonitoringsignificantlocationchanges()

🟡 Yellow Circle In front of my app Name. What does it mean ?
Hello everyone, a few months ago I started building an app using flutter, and a few days ago when I told one of my friends to test it trough Test Flight he asked me why it shows an 🟡 Yellow Circle in front of the app name ? is there an Apple documentation regarding this yellow circle so I can point others to that page ? I googled to find out about this behaviour and it says that my app uses the microphone, but I do not have any code, any library that is using the microphone, it is an Outdoor/GPS Recording app. Thank you.

iOS26 系统锁屏一段时间,蓝牙钥匙和数字钥匙都不能正常工作
Recently, we have received continuous feedback from users that the Bluetooth key and digital key are not working properly or are not functioning; Through analysis of App logs, it was found that after the iOS system locks the screen, the iBeacon background keep-alive function fails, Bluetooth connection also fails, and system callbacks cannot be obtained; the digital key also fails, and it fails simultaneously with the Bluetooth key; We have checked the specific permission configuration and it aligns with the recommended configuration in the official documentation, with no abnormalities. Although this type of issue is not a widespread problem, it has been continuously reported by users and is very troublesome. Does the official team have a clear explanation? Why are both Bluetooth keys and digital keys affected after the app is locked? Digital keys should be less affected. The following is a log analysis of a certain user 1: Step 2, the App entered the background; Step 3, the App's Bluetooth was disconnected; 3-4 The App remained in the background for 5 hours before being launched again 2: This type of issue is due to the system disconnecting the Bluetooth connection when the app enters the background; most likely, the app has been killed by the system when the user gets out of the car, and it has not been revived; the car key also does not work; During the time period from 2026-03-23T17:59:33 to 2026-03-23T21:23:49, why didn't carkey work properly 1:2026-03-23T16:52:11.676+08:00 new_carkey: key:, rssi:-89, AUTH_OK 2:2026-03-23T17:55:51.782+08:00 new_carkey: AppMonitor appDidEnterBackground bleStatus: success(Nimbus.NIOCarBLEKey.State.connected) 3:2026-03-23T17:59:33.747+08:00 new_carkey: ibeacon: didExitRegion, vid: NIO BLE Key, uuid: *** bleStatus: failure(Error Domain=CBErrorDomain Code=15 ""Failed to encrypt the connection, the connection has timed out unexpectedly.""

Maps: opening hours API / Property
I’m currently developing an iOS app that relies heavily on location details. I'm using MapKit and MKMapItem as my primary data source, which works perfectly for standard metadata. However, I’ve hit a roadblock: I want to display opening hours inline within my location details, but it seems Apple doesn't expose a public API or property for this in MKMapItem (even though the data is clearly visible in the native Apple Maps app). Since I'm building this as an indie developer/startup, the Google Places API is unfortunately too expensive for my current budget. ⁠Is there any legitimate, native way to get opening hours from Apple that I might have missed? ⁠If not, what are your best practices or recommended indie-friendly alternatives (e.g., Yelp Fusion API, OpenStreetMap, Foursquare)? Any tips on how to handle this elegantly and cost-efficiently would be highly appreciated! Thanks in advance.

Significant Location Change Event in two apps running on same device
I am using Significant Location Change (SLC) monitoring to relaunch my app after it has been terminated. I have implemented SLC in two separate apps installed on the same device, and I would like to understand how the system delivers SLC events in this scenario. Specifically: Will both apps receive the SLC event at the same time, or can there be differences in the timing of delivery? If there are differences, what factors influence when each app receives the event? What criteria or system conditions determine how and when SLC events are delivered to different apps on the same device? Any clarification on the event delivery behavior would be greatly appreciated.

Crash when iterating over CMSensorDataList via NSFastEnumeration
When iterating over a CMSensorDataList (which conforms to NSFastEnumeration) returned by CoreMotion's CMSensorRecorder's accelerometerData(from:to:) method, we sometimes see the crash below, with the frame above pointing to the close brace of the for loop iterating over the list. 0 CoreMotion 0x000000019fcf01dc CLInternalGetPinnedLocationAuthorizationState + 423316 1 CoreMotion 0x000000019fcf036b CLInternalGetPinnedLocationAuthorizationState + 423715 2 CoreMotion 0x000000019fcf02cb CLInternalGetPinnedLocationAuthorizationState + 423555 3 CoreMotion 0x000000019fbb8553 CLMotionActivity::isStatic() const + 1751823 It has been incredibly difficult to reproduce. We managed to reproduce a similar crash stack twice in a separate app that misused accelerometerData(from:to:) by providing a from and to Date that were more than 12 hours apart and iterating over the returned data, but it only occurred twice in many hours of testing. We hope to know if this could be a bug in Core Motion or it is definitely in our SDK, or if there is any way to fail gracefully in this scenario.

Direction data not available with U2 chip (iPhone 15 Pro and iPhone 16 Pro) when using Murata SR040/SR150 accessory
Hello, I am developing with the Nearby Interaction framework using third-party UWB accessories (Murata SR040/SR150). I observed a difference between U1-based and U2-based iPhones: iPhone 12 Pro (U1 chip) NINearbyObject.direction returns valid 3D vector (x, y, z). Distance and direction both work as expected. iPhone 15 Pro and iPhone 16 Pro (U2 chip) NINearbyObject.direction is always nil. Only distance is returned (around 0.35–0.40 m in my test). Effectively behaves as "distance-only mode". Environment: Hardware: iPhone 12 Pro, iPhone 15 Pro iOS version: 18.5 Accessory: Murata UWB SR040 / SR150 App: Using NINearbyAccessoryConfiguration with BLE-based discovery Info.plist includes NSNearbyInteractionUsageDescription Camera assistance was tested both ON and OFF Expectation: I expected the U2 chip to behave consistently with U1, i.e. provide direction vectors when possible. Instead, on iPhone 15 Pro, direction is always unavailable (nil) while distance is returned correctly. Questions: Is this an intentional limitation for U2 chip + third-party accessories? Is there a new requirement (e.g. certification, firmware update, capability flags) to enable direction on U2 devices? Could this be related to NIDeviceCapability or the new Extended Distance Measurement (EDM) mode in U2? Thanks in advance for any clarification.

Reliable region monitoring (geofence-based) while app is killed
I am developing an app used by public safety agencies. Part of the app is used to determine live agency staffing using geofences. For example, a geofence exists around a station, and when a user enters or exits that geofence, the app updates the staffing count at that station in real time. The issue I am having is reliably detecting when a user enters or exits the geofence while the app is killed (meaning the user force quit the app from the app launcher). I understand that iOS can relaunch an app in the background if the system terminated the process using Region Monitoring, but I haven't gotten a clear answer about whether or how this is possible if the user kills (force quits) the app. Thank you in advance for your assistance.

Significant change or restart app without location UIBackgroundModes key
Situation: We have an app that only uses location UIBackgroundModes key to restart our app on significant change events as we need it to connect with a BLE device (mounted in the car) when someone starts driving. We cannot use geofence as the car might be used by multiple people so position changes and we don't want to store locations and sent them to multiple users via our servers. So currently we use significant change and just ignore all other location data. During app review we got the following feedback: If the app does not require persistent real-time location updates, please remove the "location" setting from the UIBackgroundModes key. You may wish to use the significant-change location service or the region monitoring location service if persistent real-time location updates are not required for the app features. Question: How to use the significant-change location service without the "location" setting from the UIBackgroundModes key or is there any other way to start the app / connect with the BLE device when it is fully terminated/swiped away? Because the docs state that AuthorizationStatusAuthorizedAlways is required and without the UIBackgroundModes key location that wouldn't be triggered when app is in the background/swiped away. Reference: https://developer.apple.com/library/archive/documentation/UserExperience/Conceptual/LocationAwarenessPG/CoreLocation/CoreLocation.html#//apple_ref/doc/uid/TP40009497-CH2-SW8

Maps tokens suddenly stopped working today and now return 401 everywhere
Hi, Our Apple Maps integration has been working normally for years, but starting today, newly created Maps tokens suddenly became unusable. Tokens created from the Apple Developer backend now return 401 Unauthorized everywhere we test them. We can reproduce this in: our own code Apple’s Try Maps Server API page MapKit JS So this does not appear to be limited to our app code. We also tested through a US network entry point to rule out a mainland China network issue, but the result was the same. At the moment, Maps tokens created in the backend seem to be unusable in all cases on our side. Has anyone else seen this today, or is there any known issue affecting Maps token creation or validation? Thanks.

Direction data not available with U2 chip (iPhone 15 Pro and iPhone 16 Pro) when using Murata SR040/SR150 accessory
Hello, I am developing with the Nearby Interaction framework using third-party UWB accessories (Murata SR040/SR150). I observed a difference between U1-based and U2-based iPhones: iPhone 12 Pro (U1 chip) NINearbyObject.direction returns valid 3D vector (x, y, z). Distance and direction both work as expected. iPhone 15 Pro and iPhone 16 Pro (U2 chip) NINearbyObject.direction is always nil. Only distance is returned (around 0.35–0.40 m in my test). Effectively behaves as "distance-only mode". Environment: Hardware: iPhone 12 Pro, iPhone 15 Pro iOS version: 18.5 Accessory: Murata UWB SR040 / SR150 App: Using NINearbyAccessoryConfiguration with BLE-based discovery Info.plist includes NSNearbyInteractionUsageDescription Camera assistance was tested both ON and OFF Expectation: I expected the U2 chip to behave consistently with U1, i.e. provide direction vectors when possible. Instead, on iPhone 15 Pro, direction is always unavailable (nil) while distance is returned correctly. Questions: Is this an intentional limitation for U2 chip + third-party accessories? Is there a new requirement (e.g. certification, firmware update, capability flags) to enable direction on U2 devices? Could this be related to NIDeviceCapability or the new Extended Distance Measurement (EDM) mode in U2? Thanks in advance for any clarification.

Reliable region monitoring (geofence-based) while app is killed
I am developing an app used by public safety agencies. Part of the app is used to determine live agency staffing using geofences. For example, a geofence exists around a station, and when a user enters or exits that geofence, the app updates the staffing count at that station in real time. The issue I am having is reliably detecting when a user enters or exits the geofence while the app is killed (meaning the user force quit the app from the app launcher). I understand that iOS can relaunch an app in the background if the system terminated the process using Region Monitoring, but I haven't gotten a clear answer about whether or how this is possible if the user kills (force quits) the app. Thank you in advance for your assistance.

Significant change or restart app without location UIBackgroundModes key
Situation: We have an app that only uses location UIBackgroundModes key to restart our app on significant change events as we need it to connect with a BLE device (mounted in the car) when someone starts driving. We cannot use geofence as the car might be used by multiple people so position changes and we don't want to store locations and sent them to multiple users via our servers. So currently we use significant change and just ignore all other location data. During app review we got the following feedback: If the app does not require persistent real-time location updates, please remove the "location" setting from the UIBackgroundModes key. You may wish to use the significant-change location service or the region monitoring location service if persistent real-time location updates are not required for the app features. Question: How to use the significant-change location service without the "location" setting from the UIBackgroundModes key or is there any other way to start the app / connect with the BLE device when it is fully terminated/swiped away? Because the docs state that AuthorizationStatusAuthorizedAlways is required and without the UIBackgroundModes key location that wouldn't be triggered when app is in the background/swiped away.
