Since integrating MapKit JS, we’ve begun receiving production error reports with the following message: Uncaught DataCloneError: Failed to execute 'postMessage' on 'DedicatedWorkerGlobalScope': ArrayBuffer is not detachable and could not be cloned. It appears that MapKit JS’s internal worker occasionally calls postMessage() with an ArrayBuffer that cannot be detached under Chrome 120+. This causes the structured clone to fail and the error surfaces uncaught from within the worker. MapKit JS Version: 5.79.109 Browser: Chrome 120.0+ OS: Windows 10 Is this a known issue with MapKit JS? If so, are there recommended workarounds or planned fixes?

I have a List containing ItemRow views based on an ItemDetails object. The content is provided by a model which pulls it from Core Data. When I scroll through the list one or two of the rows will disappear and reappear when I scroll back up. I have a feeling it's because the state is being lost? Here's some relevant info (only necessary parts of the files are provided): -- ModelData.swift: @Observable class ModelData { var allItems: [ItemDetails] = coreData.getAllItems() ... } -- ItemDetails.swift: struct ItemDetails: Identifiable, Hashable, Equatable { public let id: UUID = UUID() public var itemId: String // Also unique, but used for a different reason ... } -- MainApp.swift: let modelData: ModelData = ModelData() // Created as a global class SceneDelegate: UIResponder, UIWindowSceneDelegate { // Methods in here (and in lots of other places) use `modelData`, which is why it's a global } @main struct MainApp: App { var body: some Scene { WindowGroup { MainView() } } ... } -- MainView.swift: struct MainView:

Hello, We use the Network API in our macOS ObjectiveC applications to create a small web server. With macOS Sequoia or Tahoe (not with Sonoma), downloading files from another computer using the built-in ethernet port is way too slow. Steps to reproduce: Computer A (using macOS Tahoe or Sonoma), run an application using the Network APIs to create a webserver Make sure that this computer connects to the network using the Ethernet port, there is no issue when using WiFi On computer B, make an HTTP request to download a 20MB file => it will take about 30 seconds to download => way too slow... We tested with: if on computer A you run a web server using the GCD API instead of Network, it takes 0.2 seconds to download the file => no issue on computer A disable TSO, it improves the results, but that's not a long term solution as it doesn't hold when rebooting I can provide sample code to demonstrate this if needed. This is a new issue as it's been a while we use that code,

Hi all, I work on a smart product that, for setup, uses a captive portal to allow users to connect and configure the device. It emits a WiFi network and runs a captive portal - an HTTP server operates at 10.0.0.1, and a DNS server responds to all requests with 10.0.0.1 to direct any and all request to the server. When iOS devices connect, they send a request to captive.apple.com/hotspot-detect.html; if it returns success, that means they're on the internet; if not, the typical behavior in the past has been to assume you're connected to a captive portal and display what's being served. I serve any requests to /hotspot-detect.html with my captive portal page (index.html). This has worked reliably on iOS18 for a long time (user selects my products WiFi network, iOS detects portal and opens it). But almost everyone who's now trying with iOS26 is having the automatic pop up behavior fail - usually it says Error opening page - Hotspot login cannot open the page

When I try to add the external test group to the current version of the test group, there is an error in processing the request.

Hi, I’m an iOS developer building an app with an use case that needs advanced playback on Apple Music subscription streams, specifically: • Real-time tempo change (BPM) during playback — i.e., time-stretch with key-lock, not just crossfade. • Beat-matched transitions between tracks. From what I can tell, this capability seems to exist only for approved partners and isn’t available through public MusicKit. Question: What’s the official request path to be evaluated for that restricted partner entitlement (application form, questionnaire, NDA, or internal team/BD contact)? If the entitlement identifier is internal, how can I get my account routed to the right Apple Music team? For reference, publicly announced partners include Algoriddim djay, Serato DJ Pro, rekordbox (AlphaTheta), and Engine DJ—all of which appear to implement mixing features that imply advanced playback (tempo/beat-matching) on Apple Music content. I’d prefer not to share product details publicly for the moment and can provide specifi

Our app is unable to write to its own sandbox container on macOS when run via “My Mac (Designed for iPad)”. This is not an issue when the app runs on iPhone or on iPad. This seems to affect all attempts to write to the file system including: UserDefaults Core Data (SQLite) Firebase (Analytics, Crashlytics, Sessions) File creation (PDFs, temp files, etc.) We're seeing the following errors in the console: Operation not permitted / NSCocoaErrorDomain Code=513: Permissions error when writing to disk. CFPrefsPlistSource: Path not accessible: Failure to write to UserDefaults. Cannot synchronize user defaults to disk: UserDefaults write blocked. CoreData: No permissions to create file: Core Data SQLite store can't be created. Firebase: Failed to open database: Firebase can't initialize local storage.
