New features for APNs token authentication now available
Team-scoped keys introduce the ability to restrict your token authentication keys to either development or production environments. Topic-specific keys in addition to environment isolation allow you to associate each key with a specific Bundle ID streamlining key management. For detailed instructions on accessing these features, read our updated documentation on establishing a token-based connection to APNs.

Offer Not Available: Your Account is Not Eligible for this offer. . .
We have in-app purchases live and working fine for standard subscriptions. We also have promotional offers active for existing users (to give existing users a discount as a thank you). Yet, regardless of the user type (existing vs new... we have tested with all types), we get the "Your account is not eligible for this offer" error message when clicking the discounted offer. What is the logic for determining eligibility? I'm trying to debug as it's not clear to me why this message would show up. We are using React Native IAP. In general, how does the eligibility check work? What conditions are being evaluated and compared? And what could break those conditions? I appreciate your help! DDD

MacOS Sequoia install error
Good day. Installed Sequoia Developer Beta. After that, the laptop started to behave incorrectly, programs over 1 GB stopped installing, updates were not installed, sometimes it rebooted spontaneously. Decided to roll back. With the help of another Macbook, I managed to install 14.6.1. Errors remained. Updates are not installed. Tried to restore through the recovery menu, error at 52 minutes, using a boot disk, the same error. What else can I do? Mac Book Pro M1 16gb/2tb

Handling failed transactions in Storekit 2
When simulating a Storekit error like an invalid device verification or others of that type, should we finish a failed transaction? When I test with a Storekit configuration file, all failed transactions persist after every restart. The Apple-provided sample code for Storekit 2 has transactions finished only when they are successful.

Issue with Missing Private Key After Adding Push Notification Certificate to Keychain
Hi All, I have created a Push Notification certificate from my Apple Developer account. After downloading the aps.cer file and adding it to my Keychain, the certificate was added successfully, but the private key is missing. Has anyone encountered a similar issue in the past? What could be causing this problem?

Merchant validation error on Apple Pay payment processing
Hi, I'm developer in fintech company, we have setup process for onboarding merchants for our partner and processing payments with usage of Apple Pay API. Daily system is processing ca. 10k payments but every day ca. 100 of transactions are declined because of merchant validation error: request to https://apple-pay-gateway.apple.com/paymentservices/paymentSession (with all required parameters in body) is returning response with status code 417 "statusMessage": "Payment Services Exception merchantId={root merchant id} unauthorized to process transactions on behalf of merchantId={merchant id hash} reason={merchant id hash} is not a registered merchant in WWDR and isn't properly authorized via Mass Enablement, either." Issue impacts recurring merchants, most of their transactions are processed successfully but randomly some of them are failing with such reason. All prerequisites are met: merchant have deployed 'apple-developer-merchantid-domain-association' certificate, certificates are valid and not expired. Apple Support is not able to provide any information based on provided requests timestamps. We would to know what may be the reason just part of the requests are failing and what 417 error code means.

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.

MapkitJS Snapshot
I am having issues loading in a mapkit snapshot. I get an error saying that https://domain.com and they're expecting domain.com. I have no idea what could be going wrong here. I set the domains properly in the mapkit tokens. When I click on the link it opens a new tab and loads what the data properly, but somehow in the application on production this error comes up.

AppGroup intermittent permission errors
I recently started saving a file, where I hold some app state, to an AppGroup in order to share it with my widget extension. Of the some 16k daily active users of my app, 55 are initially unable to read the file (it might not yet be created). And they are unable to write a file to the AppGroup as well. I only know this due to logging the error to Crashlytics. Error Reading: "The file “BFTPreferences” couldn’t be opened because you don’t have permission to view it. Error Code:257" My App sees this error and informs the user to restart their device. I have not been contacted by any of these users for support, so I assume the restart fixes things. Has anyone seen this before? Is restarting the device the only fix? Am I doing something wrong? The only solution I can think of currently is to save the file to the app's Documents directory and save a copy to the AppGroup for use in my extensions. At least then the main app won't have an issue and it will just be the widget unable to display data until a restart. Reading the file: do { // archive data let data = try PropertyListSerialization.data(fromPropertyList: preferences, format: .xml, options: 0) // write data do { if let groupURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: appGroupIdentifier) { let fullPath = groupURL.appendingPathComponent(preferencesFileName) try data.write(to: fullPath) } else { fatalError("Unable to find app group \(appGroupIdentifier)") } } catch { logthis("Failed to write dictionary data to disk. \(error.localizedDescription)") } } catch { logthis("Failed to archive dictionary. \(error.localizedDescription)") } Writing the file: do { if let groupURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: appGroupIdentifier) { let fullPath = groupURL.appendingPathComponent(preferencesFileName) let data = try Data(contentsOf: fullPath) if let dictionary = try PropertyListSerialization.propertyList(from: data, format: nil) as? NSMutableDictionary { preferences = dictionary } } else { fatalError("Unable to find app group \(appGroupIdentifier)") } } catch { if (error as NSError).code == NSFileReadNoSuchFileError { // file doesn't exist so create it } else { logthis("Couldn't read BFTPreferences:\(error.localizedDescription)\nError Code:\((error as NSError).code)") <--error code 257 is caught here } }

Message Filter Extension and multiple servers
In the documentation for a Message Filter Extension it states: If you have servers that can help your app extension determine how to handle a message, you must add the Associated Domains capability to your Xcode project and specify those domains. (https://developer.apple.com/documentation/sms_and_call_reporting/sms_and_mms_message_filtering/creating_a_message_filter_app_extension) The words servers and domains are in the plural. If it's possible to specify multiple servers/domains for a Message Filter Extension then how is that done? There's no documentation nor reference for that. If multiple domains can be added to the info.plist then what is the iOS behavior in that case? Can the extension supply/change which domain is used at run time?

Apple wallet pass nfc enable
on a span of 4 months we sent 2 for nfc entitlement requests and refused , no reason nothing . i mean all we want is the ability to use nfc on passes nothing else , no idea why this is so complex . with google you don’t even need a developer account and it’s for free , here we pay and we can’t even get the full functionality the passes offer , we got the hardware and the solution but we find out we need an nfc entitlement to allow passes to have nfc ? i mean our use case is very simple instead of having barcode on the passes we want them to be via nfc and we already got the nfc hardware but we find out we need nfc entitlement which we tried requesting but getting refused with no reason at all. at least tell u what is the problem what how to fix it not outright refuse without any reason at all. if anyone got any solution please provide.

AppleScript help
Hello everyone, I would like to use AppleScript to transform a .csv file. To make things easier to understand, I'm attaching two files: 1- The original file in csv format 2- The file as I'd like it to look after I've run it through the script. Here are the steps involved 1-Open the file in numbers (Note: the file is located in the download folder). 2-Delete the first 6 lines 3-Delete all font styles and cell colors 4-Combine all cells in the nature of operation column of the same operation belonging to the same date in the first cell of the operation, deleting all spaces in the text is not necessary for each operation. 5- Delete all empty lines. I hope I've made my request clear. If any of you have the knowledge to do this, if it can be done at all, I'd be very grateful for their help in writing the script. Thank you in advance. 1.csv 2.csv

macOS ImageCaptureCore does not recognise scanners
Hi All, I would like to develop a small macOS app using swift. I want to use ImageCaptureCore to access and control connected scanners ( via usb). I followed the official docs and wrote this ScannerManager. The code seems to be working without issues or warnings. I added the Hardened Runtime capability and both com.apple.security.personal-information.photos-library and com.apple.security.device.usb to the .entitlements file. As well added NSCameraUsageDescription to the Info.plist. Problem: None of my scanners do get detected (tested 2 different models). Of course, they are connected and do get recognized by the Image Capture App (and work as expected) and are listed in the systems app, too. When I connect my phone it does get detected by the func deviceBrowser(_ browser: ICDeviceBrowser, didAdd... delegate function. Thats why I believe my code is working but the app is lacking permissions to detect scanners somehow. Does anyone know something about this? I am using macOS 15.1.1 (24B91) on a M1 Pro. Many thanks in advance! class ScannerManager: NSObject, ICDeviceBrowserDelegate, ICDeviceDelegate { let deviceBrowser: ICDeviceBrowser private var currentDevice: ICDevice? private var scannerDeviceDelegate: ScannerDeviceDelegate? var isScanning = false var scanners: [ICDevice] = [] // MARK: - Initialization override init() { print("🚀 Initializing ScannerManager...") self.deviceBrowser = ICDeviceBrowser() super.init() self.deviceBrowser.delegate = self // Log the initial browsed device type mask self.deviceBrowser.browsedDeviceTypeMask = .scanner print("🔍 Starting device browser...") self.deviceBrowser.start() // Enhanced device logging if let devices = deviceBrowser.devices { print("\n📱 Connected devices overview:") print("Total devices found: \(devices.count)") if devices.isEmpty { print("⚠️ No devices currently connected") } else { devices.forEach { device in print("\n📌 Device Details:") print(" - Name: \(device.name ?? "unnamed")") print(" - Type: \(String(describing: device.type))") print(" - Transport Type: \(String(describing: device.transportType))") print(" - Status: \(device.hasOpenSession ? "In Use" : "Available")") print(" - Persistent ID: \(String(describing: device.persistentIDString))") print(" - Location: \(device.locationDescription ?? "Unknown")") print(" - Capabilities: \(String(describing: device.capabilities))") } } } else { print("⚠️ Unable to access device list") } } ...

Live Activity without Dynamic Island
Is it possible to display a live activity on the lock-screen without a dynamic island? Or at least without expanding the dynamic island more than just for a small icon? struct SomeWidgetLiveActivity: Widget { var body: some WidgetConfiguration { ActivityConfiguration(for: SomeAttributes.self) { context in } dynamicIsland: { context in DynamicIsland { DynamicIslandExpandedRegion(.leading) { // Seems to be mandatory, any way around it? } } compactLeading: { } compactTrailing: { } minimal: { } } I couldn't quite find a way. Thank you
