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.

Is it work startMonitoring from DeviceActivityMonitorExtension's eventDidReachThreshold function?
I want to monitor again from the bellow function of DeviceActivityMonitorExtension. I have the function of startMonitoring like this. override func eventDidReachThreshold(_ event: DeviceActivityEvent.Name, activity: DeviceActivityName) { super.eventDidReachThreshold(event, activity: activity) startMonitoring() } public func startMonitoring() { let startTime = DateComponents(hour: 0, minute: 0, second: 0) let endTime = DateComponents(hour: 23, minute: 59, second: 59)//DateComponents(hour: 11, minute: 0, second: 0)// let schedule = DeviceActivitySchedule( intervalStart: startTime,//DateComponents(hour: 0, minute: 0, second: 0), intervalEnd: endTime, repeats: true //warningTime: DateComponents(minute:1) ) let selection: FamilyActivitySelection = savedSelection() ?? FamilyActivitySelection() let center = DeviceActivityCenter() let selections = self.savedSelection() ?? FamilyActivitySelection() let applications = selections.applicationTokens let categories = selections.categoryTokens let webCategories = selections.webDomainTokens let store = ManagedSettingsStore() store.shield.applicationCategories = ShieldSettings.ActivityCategoryPolicy.specific(categories, except: Set()) store.shield.applications = applications store.shield.webDomains = webCategories let scheduleHard = DeviceActivitySchedule( intervalStart: startTime,//DateComponents(hour: 0, minute: 0, second: 0), intervalEnd: endTime, repeats: true //warningTime: DateComponents(minute:1) ) let event = DeviceActivityEvent( applications: selection.applicationTokens, categories: selection.categoryTokens, webDomains: selection.webDomainTokens, threshold: DateComponents(minute: 0)//timeLimitToUseApp i.e for 15 mins ) do { try center.startMonitoring( .weekend, during: scheduleHard, events: [ .weekend: event, ] ) print("ScreenTime Monitoring Started") } catch let error { print(error.localizedDescription) } } Please provide us with a solution about starting monitoring from DeviceActivityMonitoringExtension's eventDidReachThreshold function or if there is any other way.

Live Activity don't show properly in Apple Watch
I'm facing an issue with Live Activity on the Apple Watch. I followed all the configurations outlined in Apple's official documentation, but during testing, I noticed inconsistent behavior. Some devices can display the Live Activity on the Apple Watch without any issues, while others can only see it on the iPhone, even though they are running the same system version. I've already checked the permissions, and everything is set up correctly, but I still haven't found what might be causing this difference. Has anyone experienced something similar or has any debugging suggestions?

How to check for cancellation of background task
When using the old withTaskCancellationHandler(operation:onCancel:isolation:) to run background tasks, you were notified that the background task gets cancelled via the handler being called. SwiftUI provides the backgroundTask(_:action:) modifier which looks quite handy. However how can I check if the background task will be cancelled to avoid being terminated by the system? I have tried to check that via Task.isCancelled but this always returns false no matter what. Is this not possible when using the modifier in which case I should file a bug report? Thanks for your help

How to update multiTokenContexts if ApplePayPaymentRequest does not initialize multiTokenContexts
https://developer.apple.com/documentation/apple_pay_on_the_web/applepaypaymentrequest/3955945-multitokencontexts According to this document, I know that I can initialize a multiTokenContexts when initializing ApplePayPaymentRequest. But I am now facing a tricky problem. If the user's order does not require multiTokenContexts, then I will not initialize this field when I first make ApplePayPaymentRequest. When the user is in the payment process, I may update multiTokenContexts. But this time, the update is not allowed, ApplePay will be cancelled and the payment will be closed. For example, if the user's address in Apple Pay is different, I need to update multiTokenContexts to support the payment of goods to multiple merchants, which will generate an update of multiTokenContexts. MultiTokenContexts can be updated in the onshippingcontactselected method. https://developer.apple.com/documentation/apple_pay_on_the_web/applepaysession/1778009-onshippingcontactselected My question is that from the beginning, there was no multiTokenContexts to update multiTokenContexts in onshippingcontactselected, which would cause the user to close the payment and need to manually click to pay again. This user experience is not very friendly. Is there a better way for me to go from no multiTokenContexts to multiTokenContexts without interrupting the user's payment process?

NSFileCoordinator Swift Concurrency
I'm working on implementing file moving with NSFileCoordinator. I'm using the slightly newer asynchronous API with the NSFileAccessIntents. My question is, how do I go about notifying the coordinator about the item move? Should I simply create a new instance in the asynchronous block? Or does it need to be the same coordinator instance? let writeQueue = OperationQueue() public func saveAndMove(data: String, to newURL: URL) { let oldURL = presentedItemURL! let sourceIntent = NSFileAccessIntent.writingIntent(with: oldURL, options: .forMoving) let destinationIntent = NSFileAccessIntent.writingIntent(with: newURL, options: .forReplacing) let coordinator = NSFileCoordinator() coordinator.coordinate(with: [sourceIntent, destinationIntent], queue: writeQueue) { error in if let error { return } do { // ERROR: Can't access NSFileCoordinator because it is not Sendable (Swift 6) coordinator.item(at: oldURL, willMoveTo: newURL) try FileManager.default.moveItem(at: oldURL, to: newURL) coordinator.item(at: oldURL, didMoveTo: newURL) } catch { print("Failed to move to \(newURL)") } } }

WeatherKit - missing ForecastHourly field documentation
where can we find documentation on the following fields included in payloads? They're not listed alongside the other fields in the documentation linked below: https://developer.apple.com/documentation/weatherkitrestapi/hourweatherconditions precipitationIntensity snowfallAmount Or if we can get the data type, unit used, and description here that would be great

FamilyActivityPicker: manage own device AND children device
Hello, I am unable to figure out how I tell the FamilyActivityPicker whether it should show apps installed on my personal device (to be used with AuthorizationCenter.shared.requestAuthorization(for: .individual)) or apps installed on my child’s device (authenticated their phone via AuthorizationCenter.shared.requestAuthorization(for: .child)). Is there any parameter or SwiftUI modifier I need to apply? Otherwise, how does the user or the app know which token belongs to them and which token belongs to their child’s device? Radar: FB17020977 Thanks a lot for your help!

Verify Receipt is not found - After successful payment for Annual subscription.
The application is developed with Xamarin Framework and it is live now. The customer installed the app and purchased the annual subscription. And for some reason, they uninstall and reinstall the application on the same device. Now user wants to restore the subscription. In the application, there is an option to Restore the subscription. But restore API not return purchase details. But when clicking the subscription button instead of restoring the subscription, it says you subscribed to this plan". is there any possibility of not getting VerifyRecipt even after a successful purchase?

Secure Integration of Apple Calendar (iCalendar) in a Third-Party App
Hi everyone, We’re integrating Apple Calendar (iCalendar) into our Codapet app but haven’t found any official Apple APIs for event management and synchronisation. Currently, we use CalDAV with Apple ID authentication and an app-specific password (ASP), storing the ASP encrypted in our database and decrypting it for each API call. We’re looking for a more secure and recommended approach to this integration. Does Apple provide dedicated APIs for calendar sync, or is there a better alternative to avoid sending the ASP with every request? Any guidance or best practices would be greatly appreciated! Thanks!

Issues with Integration of Promotional Offers in React Native app
Hi All, We are trying to integrate Promotional Offer in our app, We have a React Native app and are using react-native-iap for handling our in app purchases, as per the documentation we are generating signature in our BE and passing the proper details to the function as well, but for subscription request which have offer applied we are getting the apple pop up properly as well with offer details but when trying to subscribe it gives us SKErrroDomain: 12, for subscription without applying offer the subscription goes through but when we apply the offer we get the above error. Our app is currently in Development Stages and has not been sent for review sam for our subscription plans as well. Please let me know what could be the probable cause for this and help us resolve the issue. This is the code snippet of ours for the front end : export const buySubscription = async (subscriptionData: any) => { try { if (subscriptionData.offer_id) { const response = await getSubscriptionSignature( subscriptionData.productId, subscriptionData.offer_id, ); const offerData = response?.data; const offer = { identifier: offerData?.offer_id, keyIdentifier: offerData?.key_id, nonce: offerData?.nonce, signature: offerData?.signature, timestamp: Number(offerData?.timestamp), }; await requestSubscription({ sku: subscriptionData.productId, withOffer: offer, }); } else { await requestSubscription({ sku: subscriptionData.productId }); } } catch (err) { logger.error('Subscription error: ' + JSON.stringify(err)); throw err; } }; and 
from my python Backend which generates the signature:

def generate_signature(self, product_id: str, offer_id: str) -> dict: """ Generate signature for Apple StoreKit promotional offers. Args: product_id: The product identifier from App Store Connect offer_id: The promotional offer identifier Returns: dict: Contains signature and required metadata Reference: https://developer.apple.com/documentation/storekit/in-app_purchase/original_api_for_in-app_purchase/subscriptions_and_offers/implementing_promotional_offers_in_your_app """ try: # Generate UUID without dashes and use as nonce nonce = str(uuid.uuid4()) timestamp = get_current_time_ms() # milliseconds # Create the payload string in exact order required by Apple payload_components = [ self.bundle_id, # App Bundle ID self.key_id, # Key ID from App Store Connect product_id, # Product identifier offer_id, # Promotional offer identifier nonce, # UUID without dashes str(timestamp) # Current timestamp in milliseconds ] payload_str = "\u2063".join(payload_components) # Use Unicode separator logger.debug(f"Signing payload: {payload_str}") # Create SHA256 hash of the payload digest = hashes.Hash(hashes.SHA256()) digest.update(payload_str.encode('utf-8')) payload_hash = digest.finalize() # Sign the hash using ES256 (ECDSA with SHA-256) signature = self.private_key.sign( data=payload_hash, signature_algorithm=ec.ECDSA(hashes.SHA256()) ) # Encode signature in base64 signature_b64 = base64.b64encode(signature).decode('utf-8') logger.info(f"Generated signature for product {product_id} and offer {offer_id}") return { "key_id": self.key_id, # Changed to match Apple's naming "nonce": nonce, # UUID without dashes "timestamp": timestamp, # As integer "signature": signature_b64, # Base64 encoded signature "product_id": product_id, # Changed to match Apple's naming "offer_id": offer_id # Changed to match Apple's naming } except Exception as e: logger.error(f"Failed to generate signature: {str(e)}") raise HTTPException( status_code=500, detail=f"Failed to generate signature: {str(e)}" )

Unblocking Apps After a Scheduled Duration in FamilyControl
I am able to block apps using FamilyControl and Shield. Unblocking is also simple—just assign nil to store.shield.applications. However, I want to unblock them even when the app is not open. Use case: Let's say the app allows users to create a session where a particular app is blocked for a specific duration. Once the session starts, the app should remain blocked, and as soon as the session time ends, it should automatically be unblocked. Please help me with this. Thank you!

Is it possible to use an additional local ModelContainer in a document based SwiftData app?
I have a document based SwiftData app in which I would like to implement a persistent cache. For obvious reasons, I would not like to store the contents of the cache in the documents themselves, but in my app's data directory. Is a use case, in which a document based SwiftData app uses not only the ModelContainers from the currently open files, but also a ModelContainer writing a database file in the app's documents directory (for cache, settings, etc.) supported? If yes, how can you inject two different ModelContexts, one tied to the currently open file and one tied to the local database, into a SwiftUI view?

Gathering Required Information for Troubleshooting Wallet Issues
Hi, To ensure the issue is not caused by an error within your app or web service request, please review the following documentation: Wallet Passes Wallet Developer Guide If the resources above don’t help identify the cause of the error, please provide more information about your app or web services to get started. To prevent sending sensitive credentials in plain text, create a report in Feedback Assistant to share the details requested below. Additionally, if the error is something we need to investigate further, the appropriate engineering teams also have access to the same information and can communicate with you directly within Feedback Assistant for more information, as needed. Please follow the instructions below to submit your report. For issues occurring with your native app or web service, perform the following steps: Install the Wallet profile on your iOS or watchOS device. Reproduce the issue and make a note of the timestamp when the issue occurred, while optionally capturing screenshots or video. Gather a sysdiagnose on the same iOS or watchOS device. Create a Feedback Assistant report with the following information: The serial number of the device. Open Settings > General > About > Serial Number (tap and hold to copy). The SEID (Secure Element Identifier) of the device, represented as a HEX encoded string. Open Settings > General > About > SEID (tap and hold to copy). The sysdiagnose gathered after reproducing the issue. The .pkpass file(s), pass signing certificate(s) and pass type identiifier(s) (optional). The timestamp of when the issue was reproduced. Screenshots or videos of errors and unexpected behaviors (optional). Important: From the logs gathered above, you should be able to determine the cause of the failure from PassbookUIService, PassKit or PassKitCore, and by filtering for your SEID or pass type identifier in the Safari Web Inspector. See Inspecting Safari on macOS to learn more. Submitting your feedback Before you submit to Feedback Assistant, please confirm the requested information above is included in your feedback. Failure to provide the requested information will only delay my investigation into the reported issue within your Wallet pass implementation. After your submission to Feedback Assistant is complete, please respond in your existing Developer Forums post with the Feedback ID. Once received, I can begin my investigation and determine if this issue is caused by an error within your web implementation, a configuration issue within your developer account, or an underlying system bug. Cheers, Paris X Pinkney |  WWDR | DTS Engineer

Weatherkit API Historical 404 Errors Starting 3/5/25
We've been using the WeatherKit API for a few years now. Everything has been pretty stable. We'll periodically get 404 errors, but they usually disappear within a couple days. Starting March 5th we've again been getting 404 errors that slowly ramped up to March 20th and continued. We have had no code changes on our end, so something seems to have changed / broken on the server side of things. Here are some example API calls that are giving us a 404 error now https://weatherkit.apple.com/api/v1/weather/en/35.9981205/-78.8920444?dataSets=forecastDaily&dailyStart=2025-03-21T05:00:00Z&timezone=America/New_York&countryCode=US https://weatherkit.apple.com/api/v1/weather/en/41.4789363/-81.7404134?dataSets=forecastDaily&dailyStart=2025-03-21T04:56:00Z&timezone=America/New_York&countryCode=US Does anyone have any insights or information on this? Also if Apple is listening, an error more meaningful than 404 would be much much appreciated.

Dev Defined IAP Transaction Metadata
I have an app that works by being able to map IAP transactions to a predefined user ID. This means when I consume events from Apple's App Store Server Notifications endpoints I have to do a reverse lookup in order to assign permissions within my app. Workflow: User purchases subscription within the app via IAP. The app persists the subscriptionID from the Apple IAP library in my cloud database (Firestore). Cloud function receives the event from App Store Server Notifications endpoint and looks up the user ID containing the persisted transactionID (with retries to avoid race condition). Question: This workflow works but it seems an improvement would be to allow dev's to append metadata, like the user ID, to the transaction submitted to IAP that we can access within the signedTransactionInfo of the event from the App Store Server Notifications endpoint in order to facilitate a direct lookup of the user document needing it's permissions updated. This would greatly simplify workflows that use non-Apple systems as a source of truth for app permissions. Does this actually exist already? If not, is there a feature request platform?

iOS Blocking Websocket Reconnection After Multiple VoIP Push Notifications
Hello, We have a Push-to-Talk (PTT) application that is already well established and widely used. Our app has the proper VoIP entitlement, which we are using to wake up the app and establish a WebSocket connection for real-time communication. We are also using CallKit as a supporting mechanism, but not as the primary interaction upon receiving the VoIP Push, since our use case differs from traditional full-duplex VoIP calls. While our implementation works correctly in many cases, we have noticed a consistent issue where, after multiple VoIP Push notifications, the system still delivers the push, but prevents the WebSocket from reconnecting. At this point, all connection attempts return errors such as: • "Software caused connection abort" This issue persists until the app is manually relaunched, after which the behavior resets and repeats. We are aware that VoIP Push was originally designed for full-duplex calls, but since Apple allows its use for other purposes through the entitlement, we would like to understand why this limitation is occurring and how to handle it properly. Questions: 1. Is iOS enforcing stricter background execution rules after multiple VoIP Push events within a short period? 2. Are there any recommended best practices to ensure reliable WebSocket reconnection in this scenario?
