Getting ASAuthorizationError 1004 (notInteractive) when testing web credential sharing with Apple sample app
Using both the Apple sample app for passkeys (link below) and another barebones sample app from github (link below), we are getting this same error when trying to retrieve a user's passkey that has been created from our website associated with the sample app: ASAuthorizationController credential request failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 "(null)" Error: ["NSLocalizedFailureReason": Unable to verify webcredentials association of TEAMID.com.company.product with domain app.company.com. Please try again in a few seconds.] Note I have replaced TEAMID, the bundle id and the website id here, but the values match our site association file, which has this content: { "webcredentials": { "apps": [ "TEAMID.com.company.product" ] } } and is hosted at: https://app.company.com/.well-known/apple-app-site-association (returned with Content-Type: application/json header) The enum values for ASAuthorizationError.Code I believe are: canceled: 1000 failed: 1001 invalidResponse: 1002 notHandled: 1003 notInteractive: 1004 unknown: 1005 Thus we are getting notInteractive, which according to another forum post here, we should not be seeing. With both sample apps, I've made sure the request to perform authentication is triggered from a button press by the user. Can someone please help us figure out why we are getting this error? Xcode version: 16.2 MacOS version: 15.2 iOS version: 18.2 iPhone model: iPhone SE (MHGT3X/A) Link for Apple sample app: https://developer.apple.com/documentation/authenticationservices/connecting_to_a_service_with_passkeys Link for Github sample app: https://github.com/hansemannn/iOS16-Passkeys-Sample

Is original_transaction_id and transaction_id globally unique?
Hello, Apple App Store Server API Team! I have one questions about the identifiers provided by Apple App Store Server API. Could you please answer? We are running an iOS App. In our app, the transactionId we get from Apple App Store Server API is called T1. (Example) Q1. Is it correct that other iOS apps cannot get T1 for transactionId from Apple App Store Server API? (I'm wondering if the transactionId is globally unique across apps.) Thank you!

How to identify a user who performed action which is reported by Endpoint Security
Hello, My application monitors ES_EVENT_TYPE_NOTIFY_CLOSE. If a file is dragged to another location in Finder, the Endpoint Security reports the event ES_EVENT_TYPE_NOTIFY_CLOSE was performed by '/usr/libexec/xpcproxy'. So, xpcproxy is the process that performed ES_EVENT_TYPE_NOTIFY_CLOSE. Looks like the dragged file is copied by some XPC service. I have found the audit user id is equal to user who dragged a file. Can audit user id be used to identify a user who triggers copy file action in this case? If no, are there any way to define such info? Thank you in advance!

CloudKit Dashboard error "Failed to execute query"
Something has caused my CloudKit queries to fail. On the dashboard I get an error message "Failed to execute query" when I try to "SORT BY" a field. The field is listed under Indexes as "sortable". For a different field, when I enter the field under "FILTER BY", and before I tap "Query", I get "No results". That field is listed under the Indexes as "queryable". It used to work fine. I have described this further, with screenshots at FB16114560

Sleep Analysis inBed sample not recorded on Apple Watch in iOS 18
In this link, Apple states we can know when a user is in bed vs sleeping and compare their quality of sleep by it. Only, in iOS 18, Apple no longer reports inBed time samples for the Apple Watch. I get why they stopped doing this for the phone, but why the watch? Bug? My app was using the inBed times for this very purpose and now only works for Garmin and Oura who still report inBed times. https://developer.apple.com/documentation/healthkit/hkcategoryvaluesleepanalysis

Alternate App Icons not working in test flight
I've been working on implementing alternate app icons for my iOS app, and everything works perfectly in debug builds on both the simulator and a physical device. However, when testing on TestFlight, I encounter the following error: The requested operation couldn’t be completed because the feature is not supported. Has anyone faced this issue before? Is there a specific TestFlight configuration or setup I might be missing to enable alternate app icon functionality?

Handling Data Download Backpressure in URLSession
I am developing an application that processes a video file stored on a server. I use URLSessionDataTask with a delegate handler to download the file. It is not necessary to download the entire file at once. Instead, I can load small chunks of the file as needed. This approach helps minimize memory consumption. I am trying to design a network layer that supports this behavior. Ideally, I would like to have an interface similar to: func readMoreData(length: Int) async throws -> Data Problems I Encountered: It seems that URLSessionDataTask does not allow controlling how many bytes will be downloaded. It always downloads the entire request. If I call suspend on URLSessionDataTask, the network activity does not stop, and the file keeps downloading. If I upgrade the dataTask to a StreamTask, the file still downloads, though reading bytes can be done through the StreamTask API. I would prefer behavior similar to AsyncHTTPClient (a Swift Server library) or Network Framework. These frameworks allow controlling the number of bytes downloaded at a time. Unfortunately, they do not fit the specific requirements of my project. Am I correct in understanding that controlling the download process is not possible with URLSessionDataTask? As a possible solution, I am considering using HTTP Range Requests, though this would increase the number of additional server requests, which I would like to avoid.

Missing calls to L2CAP Stream Delegate
I have a C++/Objective-C command line application, running on MacOs (15.1.1 (24B91)), that communicates with a Bluetooth LE peripheral. The application is build with Apple clang 16.0.0 and CMake as build system using Boost.Asio. I'm able to establish a L2CAP channel and after the channel is established, the peripheral sends a first (quite small) SDU on that channel to the application. The PSM is 0x80 and was chosen by the peripherals BLE stack. The application receives the PSM via GATT notification. I can see the SDU being send in a single LL PDU with Wireshark. I can also see the SDU being received in Apples PacketLogger. But I miss the corresponding call to a stream event handler. For all other GATT related events, the corresponding delegates / callbacks are called. The code that creates a dispatch queue and passes it to the CBCentralManager looks like this: dispatch_queue = dispatch_queue_create("de.torrox.ble_event_queue", NULL); manager = [[CBCentralManager alloc] initWithDelegate:self queue:dispatch_queue options:nil]; When the L2CAP channel is established, the didOpenL2CAPChannel callback gets called from a thread within the dispatch_queue (has been verified with lldb): - (void)peripheral:(CBPeripheral *)peripheral didOpenL2CAPChannel:(CBL2CAPChannel *)channel error:(NSError *)error { [channel inputStream].delegate = self; [channel outputStream].delegate = self; [[channel inputStream] scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [[channel outputStream] scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [[channel inputStream] open]; [[channel outputStream] open]; ... // a reference to the channel is stored in the outside channel object [channel retain]; ... } Yet, not a single stream event is generated: - (void)stream:(NSStream *)stream handleEvent:(NSStreamEvent)event_code { Log( @"stream:handleEvent %@, %lu", stream, event_code ); ... } When I add a functionality, to poll the input stream, the stream will report the expected L2CAP input. But no event is generated. The main thread of execution is usually blocking on a boost::asio::io_context::run() call. The design is, to have the stream callback stream:handleEvent to post call back invocations on that io_context, and thus to wake up the main thread and get that callbacks being invoked on the main thread. All asynchronous GATT delegate calls are working as expected. The only missing events, are the events from the L2CAP streams. The same code worked in an older project on an older version of MacOs and an older version of Boost. How can I find out, why the stream delegates are not called?

Gift Subscription and Split Payment
I am the Lead iOS Developer for The Incc, an upcoming social networking application. The platform offers subscriptions that grant users access to premium content, primarily digital magazines showcasing diverse cultures, alongside standard social media features and additional unique functionalities. I am exploring two specific use cases for our subscription model. Promo Codes with Split Payments: We plan to collaborate with the our influencers (referred to as Mover Shakers) by providing them with promo codes for users to purchase subscriptions. For such purchases, we aim to implement a revenue split model, allocating 10% to the influencer and the remainder to us after Apple’s fees. Gifting Subscriptions: We also wish to enable users to gift subscriptions to others within the app. I understand that the Apple Subscription Service does not natively support these features. What other options do we have to achieve this that are also not against the Apple's guidelines.

The message filtering documentation is offline
Hello the documentation for message filtering has been offline for a few days now, is it possible to get it back, or is there somewhere else it can be viewed in the meanwhile? https://developer.apple.com/documentation/sms_and_call_reporting/sms_and_mms_message_filtering (I just chose topic/tags at random, there aren't any relevant for this)

IOUSBHostInterface::Open for interrupt interfaces works on iPad Air but not iPad Pro
I am trying to open the CommunicationControl class IOUSBHostInterface in my USB driver, but it only seems to open on iPad Airs and not iPad Pros. I'm calling ivars->interruptInterface->Open(this, 0, NULL); After retrieving the interruptInterface from the device's InterfaceIterator. I try and open this, but on iPad Pros it returns kIOReturnNotOpen. I've tried closing and reopening the IOUSBHostDevice, closing and reopening the Interface, AbortDeviceRequests before opening, etc. but it just seems to work on iPad Air and not iPad Pro. I've tried on both iPadOS 17.6.1 and 18.2 Has anyone else seen this?

SwiftData + CKSyncEngine
Hi, I'm building a habit tracking app for iOS and macOS. I want to use up to date technologies, so I'm using SwiftUI and SwiftData. I want to store user data locally on device and also sync data between device and iCloud server so that the user could use the app conveniently on multiple devices (iPhone, iPad, Mac). I already tried SwiftData + NSPersistentCloudKitContainer, but I need to control when to sync data, which I can't control with NSPersistentCloudKitContainer. For example, I want to upload data to server right after data is saved locally and download data from server on every app open, on pull-to-refresh etc. I also need to monitor sync progress, so I can update the UI and run code based on the progress. For example, when downloading data from server to device is in progress, show "Loading..." UI, and when downloading finishes, I want to run some app business logic code and update UI. So I'm considering switching from NSPersistentCloudKitContainer to CKSyncEngine, because it seems that with CKSyncEngine I can control when to upload and download data and also monitor the progress. My database schema (image below) has relationships - "1 to many" and "many to many" - so it's convenient to use SwiftData (and underlying CoreData). Development environment: Xcode 16.1, macOS 15.1.1 Run-time configuration: iOS 18.1.1, macOS 15.1.1 My questions: 1-Is it possible to use SwiftData for local data storage and CKSyncEngine to sync this local data storage with iCloud? 2-If yes, is there any example code to implement this? I've been studying the "CloudKit Samples: CKSyncEngine" demo app (https://github.com/apple/sample-cloudkit-sync-engine), but it uses a very primitive approach to local data storage by saving data to a JSON file on disk. It would be very helpful to have the same demo app with SwiftData implementation! 3-Also, to make sure I don't run into problems later - is it okay to fire data upload (sendChanges) and download (fetchChanges) manually with CKSyncEngine and do it often? Are there any limits how often these functions can be called to not get "blocked" by the server? 4-If it's not possible to use SwiftData for local data storage and CKSyncEngine to sync this local data storage with iCloud, then what to use for local storage instead of SwiftData to sync it with iCloud using CKSyncEngine? Maybe use SwiftData with the new DataStore protocol instead of the underlying CoreData? All information highly appreciated! Thanks, Martin
