How to identify which minor user's authorization has been revoked by the parent/guardian?
I followed the method outlined in Apple's documentation to test "Revocation of Consent." Our server received the notification sent by Apple, but the parsed data only contains the following content (some data has been modified for privacy, but the fields remain unchanged): { "receiptType": "Sandbox", "bundleId": "com.xxx.xxxxx", "receiptCreationDate": 1764932591296, "requestDate": 1764932591296, "originalPurchaseDate": 1375340400000, "originalApplicationVersion": "1.0", "appTransactionId": "705020051250081000", "originalPlatform": "iOS" } How can we identify that "a parent/guardian has revoked authorization for a specific user"? We are unable to determine which minor user should be restricted from using certain features of our app. I hope to receive a prompt response from Apple's technical experts! Thanks A Lot !

blockedApplications api to HIDE app categories?
Is there any way to use blockedApplications to hide all apps in a category? Currently, I use blockedApplications to hide individual apps, but it doesn’t work when I select an entire category. I thought the only solution would be to use shield, which doesn’t hide the apps but creates a blocking shield. However, I found an app on the App Store called Fokus, and it’s able to select a category and block all the apps in it. Does anyone know how this could be possible?

Universal Link always shows “Open App A?” banner instead of redirecting automatically
We have a login flow where the user authenticates in Safari, and at the end of the process the authentication server redirects back to our app using a Universal Link. On most devices, the app opens automatically without any confirmation banner. However, on several iPads, Safari always shows the “Open App A?” banner after the redirect. The user must tap Open every time. Other devices running the same iOS version do not show this issue. Expected Flow (working devices): Start authentication Safari login Authentication server redirects using a Universal Link App A opens automatically Problematic Flow (several iPads): Start authentication Safari login Authentication server redirects using a Universal Link Safari shows “Open App A?” confirmation banner User must tap Open App A starts Questions: Is this a known issue in iOS? Or is this expected behavior under certain conditions (i.e., is there a specific Safari/iOS specification that causes this banner to appear)? Is there any way to prevent Safari from showing the “Open App A?” banner and allow automatic redirection? *This issue did not occur on iOS 16, but it started appearing after updating to iOS 17. Devices : iPad 9th Gen/iPad 10th Gen

ExtendedDistanceMeasurement in Nearby Interaction Framework not working on iOS 26
Problem Description: After upgrading to iOS 26, I discovered that the ExtendedDistanceMeasurement feature in the Nearby Interaction framework is not working as expected. On the same device model, the issue did not occur on iOS 18, but it is present on iOS 26 (including the latest iOS 26.2), and it has started affecting the functionality of my app. I hope this issue can be resolved as soon as possible. Problem Details: On iOS 26 and later versions (including iOS 26.2), when using an iPhone and an Apple Watch both equipped with second-generation UWB chips, enabling isExtendedDistanceMeasurementEnabled initiates the distance measurement process successfully, but the distance information fails to update. The real-time distance between the devices does not display within the app. Affected Devices and Versions: iPhone Model: iPhone 15 Pro Max iOS Version: iOS 26.2 Apple Watch Model: Apple Watch 10 watchOS Version: 26.2 Example Code: The issue can be reproduced by adding the following code to the official sample code: Nearby Interaction Framework Sample Code private func didReceiveDiscoveryToken(_ token: NIDiscoveryToken) { if session == nil { initializeNISession() } if !didSendDiscoveryToken { sendDiscoveryToken() } os_log("running NISession with peer token: \(token)") let config = NINearbyPeerConfiguration(peerToken: token) // The issue can be reproduced by adding the following code to the official sample code // Enable extended distance measurement if both devices support it if NISession.deviceCapabilities.supportsExtendedDistanceMeasurement && token.deviceCapabilities.supportsExtendedDistanceMeasurement { config.isExtendedDistanceMeasurementEnabled = true } session?.run(config) } Problem Behavior: When either the iPhone or the Apple Watch does not support the second-generation UWB chip (i.e., deviceCapabilities.supportsExtendedDistanceMeasurement = false), the code works as expected. However, when both the iPhone and the Apple Watch support the second-generation UWB chip (i.e., deviceCapabilities.supportsExtendedDistanceMeasurement = true), the code fails to work, and the distance does not update — meaning the real-time distance between the devices is not displayed. Expectation: I hope this issue can be resolved soon, as it is impacting my app. The problem persists in the latest iOS 26.2, and has yet to be fixed.

How to determine TX region when using Declared Age Range (SB2420 compliance)
Hello, I’m working on implementing SB2420 compliance using the Declared Age Range framework. While referring to the documentation at https://developer.apple.com/documentation/declaredagerange, I couldn’t find details on how the TX region (transaction region or territory) is determined when using Declared Age Range. Specifically, I’d like to confirm the following points: How does the system determine the TX region when the user’s declared age range is retrieved? Is it based on the App Store region, the device locale, or the user’s Apple ID country? If the app’s backend needs to verify or log the TX region, is there a way to obtain or infer it from the API response or receipt data? Is there any difference in TX region determination between Sandbox and Production environments? If anyone has experience implementing Declared Age Range (SB2420) and handling region determination, I’d appreciate your insights or best practices. Thank you.

Can the App Clip banner for full app download be disabled?
Hello, I have a question about the default UI in an App Clip. I know that when App Clip launches, a system banner appears at the top for a few seconds, prompting the user to download the full app from the App Store. I'd like to confirm if this is the standard, default behavior for all App Clips. More importantly, is there any way to disable or hide this banner? We would prefer to manage the prompt to download the full app within our own UI. Thanks in advance for your help!

SMS Filter Extension - No Categories showing
Hi, I developed an iOS app which will do SMS filtering by following this documentation. https://developer.apple.com/documentation/identitylookup/sms-and-mms-message-filtering) I built the app and send Test Flights to different testers. All the Testers from Sri Lanka (an asian country) says filtering is working and they can see all the enabled categories on the Messages too (including iOS 26). But the testers from Mexico cannot see the categories and filtering is not working. On official documentation there is nothing about supported countries. But I found true caller article https://support.truecaller.com/support/solutions/articles/81000406341-how-do-i-enable-sms-filtering-on-iphone mentioning it support only few countries for SMS filtering. Currently available in the following countries: India, Nigeria, South Africa, Kenya, Bangladesh, Sri Lanka. Our previous Categories filtering are still available for: Australia, Bahrain, Canada, Ghana, Tanzania, United Kingdom, United Arab Emirates, United States of America, Zambia Following article https://clearstream.io/blog/ios-26-iphone-new-text-message-filtering is saying some categories are supported by only Brazil and India. Still I could not find any official documentations saying different country supports.

FinanceKit - Any way to get merchant location info from transactions?
Hi all — I’m building a Wallet-style transaction details view using FinanceKit and I’m running into a gap around merchant location. What I’m seeing FinanceKit gives me great core fields (amount, currency, status, dates, MCC, merchantName, transactionDescription), but I’m not seeing any address or place/location metadata on a Transaction. For example, a small/local merchant where I can plausibly infer a single place: Fetched transaction: Transaction( id: 8D142B16-3E0E-40B8-945A-2E7C0CF65F1D, accountID: 14939CF4-DBC3-4A9D-8292-5FEA495B8461, transactionAmount: 47.24 USD, creditDebitIndicator: .debit, transactionDescription: "Local Dental Care", originalTransactionDescription: "Local Dental Care", merchantCategoryCode: 8021, merchantName: "Local Dental Care", transactionType: .pointOfSale, status: .booked, transactionDate: 2025-08-20 22:27:50 +0000, postedDate: 2025-08-21 11:22:06 +0000 ) Because this appears to be a single-location practice, I can usually resolve it to a place using MapKit search heuristics. But for big-box chains, I don’t get enough signal to determine which store: Fetched transaction: Transaction( id: 3F8E9F74-7565-4D24-9038-8FD709184799, accountID: 14939CF4-DBC3-4A9D-8292-5FEA495B8461, transactionAmount: 441.77 USD, creditDebitIndicator: .debit, transactionDescription: "The Home Depot", originalTransactionDescription: "The Home Depot", merchantCategoryCode: 5200, merchantName: "The Home Depot", transactionType: .pointOfSale, status: .booked, transactionDate: 2023-12-27 23:07:02 +0000, postedDate: 2023-12-29 03:09:41 +0000 ) There’s no store number, address, phone, or any stable identifier. With hundreds of locations, I can’t deterministically choose a map pin or fetch the right brand assets. What I’m trying to achieve I’d like to replicate the Apple Wallet experience: show a small map snapshot and merchant visuals (logo/name that match Apple Maps / the Place Card) on the transaction detail screen. Without a location hint, I have to either: Ask users to pick a store manually, or Make a guess based on a coarse, app-defined region …neither of which feels great. Questions Is there any way in FinanceKit today to access merchant location or a resolvable identifier (e.g., address, city/state, store number, Apple Maps place identifier, network merchant ID/MID, terminal ID, etc.)? If not, can FinanceKit expose additional merchant metadata (even opt-in / privacy-preserving) to enable Wallet-like enrichment? A few examples that would unblock this: merchantAddress (or components: street/city/region/postalCode/country) merchantPhone (often unique per store) merchantIdentifier (stable per physical location, e.g., network merchant ID / store number) mapsPlaceURL or mapsPlaceIdentifier (linkage to the Apple Maps Place Card) brandAssetURL (logo/brand reference similar to what Wallet shows) With even one of the above, I could reliably: Render an accurate map snapshot, Fetch the correct brand assets, and Avoid prompting the user or inferring via fuzzy search. Context / constraints I do not want to (and shouldn’t need to) request or monitor the user’s device location to resolve a merchant’s store location. For small merchants, MapKit text search is often enough. For large chains, I need a store-level identifier. If there’s an existing field or recommended approach I’m missing, I’d love pointers. If not, please consider this a feature request for richer merchant metadata in FinanceKit so developers can build Wallet-quality transaction details. Thanks!

ASAM supported App on MacOS
I'd like to write a MacOS App that makes use of the ASAM functonality as described here: https://developer.apple.com/documentation/devicemanagement/autonomoussingleappmode I have tried to use the example with Safari, and have enrolled a Mac with MDM and installed the profile. But when opening Safari it does not appear in Single App Mode. I've only tried it with Safari so far but eventually I want to be able to use my own App. Is there an API that has to be used to enter single app mode programmatically? I've found the whole Assessment API but as I do not have the required entitlements to use that API I'm looking for another solution. The documentation on ASAM does not mention the Assessment API at all, is it the only way to enter "a" single app mode on MacOS? How is the Assessment API linked to ASAM? As far as I have understood there's the com.apple.developer.automatic-assessment-configuration entitlement but apps having this do not need to be configured via MDM? I'm really confused as to what's actually required to be able to get into single app mode on MacOS. The app I'm trying to write isn't really related to an an assessment task, but I am doing this for an academic institution so maybe requesting the entitlement would be feasable. The documentation on ASAM also mentions that the App is granted access to the "Accessibility" API and I've found the whole UIAccessibility/requestGuidedAccessSession but this does not seem to be available on MacOS proper? Any help on this would be greatly appreciated.

iPad widget bug
Widgets on the widget is not responding to the touch properly. This issue is also affecting within the home screen widget in a way that the widget switches to light mode by itself even though I am in dark mode. Additionally, lock screen does not to respond once the lock screen widget has been edited. Is anyone else having this issue?

WeatherKit entitlement and key not propagated — WeatherDaemon fails to generate JWT (Code=2)
Hello Apple Developer Support Team, I am the Account Holder of my Apple Developer Program team (Team ID: T2BKUF6E93). My iOS app is using Swift WeatherKit (WeatherService) on device. Although my environment is completely configured, the system WeatherDaemon consistently fails to generate the WeatherKit JWT token. My environment: Team type: Apple Developer Program (paid) Team ID: T2BKUF6E93 Account role: Account Holder Xcode: latest version Device: iPhone (real device) Provisioning Profile: iOS Team Provisioning Profile (auto-managed) Entitlement: com.apple.developer.weatherkit included WeatherKit Key: created successfully (.p8 downloaded) Bundle ID: correct and WeatherKit capability enabled App reinstalled after each configuration change Device rebooted Even after enabling WeatherKit capability and generating a WeatherKit Key, the system still fails to generate JWT: Failed to generate jwt token for: com.apple.weatherkit.authservice Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" The error persists across: multiple device restarts full clean/rebuild in Xcode deleting and reinstalling the app pulling the latest provisioning profiles waiting more than several hours for backend propagation What I suspect My WeatherKit entitlement and/or WeatherKit Key may not be fully propagated to the provisioning server or WeatherDaemon backend, even though everything appears correctly configured on the Developer Center. I kindly request the support team to: Verify whether the WeatherKit Entitlement is correctly attached to my app ID and provisioning profile. Verify whether my WeatherKit Key is properly registered and propagated for my team. Check if there are any backend propagation delays or stuck states for my Team ID (T2BKUF6E93). Confirm whether WeatherDaemon has permission to generate JWT for my app. Thank you Please let me know if any logs, screenshots, or provisioning profile identifiers are needed. Thank you for your help! Best regards, Jiangyang

Create custom internet account on macOS
Hi, A lot of e-mail providers supports OAuth2 authentication. However, Mail.app on macOS and iOS do not support configuring a mail account that would use OAuth2 authentication, unless it's on its hardcoded list of account providers. Is there any framework that allows setting up a custom account for my institution, so that we could begin to offer OAuth2 authentication for mail and calendar?

A Summary of the WWDC25 Group Lab - watchOS (Part 1)
At WWDC25 we launched a new type of Lab event for the developer community - Group Labs. A Group Lab is a panel Q&A designed for a large audience of developers. Group Labs are a unique opportunity for the community to submit questions directly to a panel of Apple engineers and designers. Here are the highlights from the WWDC25 Group Lab for watchOS (part 1). 1. I'm really excited about the new design system on all platforms. Liquid Glass is super cool. What do developers need to keep in mind when building for watchOS 26? To adopt the new design system, start with updating your app for watchOS 10 – If you have done so, your app will be mostly ready for watchOS 26. For more information, see Design and build apps for WatchOS 10. You can then look into Liquid Glass specific APIs to fine tune your app. This topic is covered in Adopting Liquid Glass. If you have SwiftUI views using any custom style, make sure they are still legible and fit with the new design system. 2. Something that really stood out to me were updates to the Smart Stack, with the system prioritizing Widgets when they're most relevant. Tell me more about these new opportunities for apps. Workout apps that record workouts using HealthKit may be automatically suggested on the watch face and appear in the Smart Stack without adding a widget. Relevant widgets are a great way to present information related to a date, location, point-of-interest type, sleep schedule, or fitness condition in the Smart Stack when it is relevant. Relevant widgets don't need to display a empty state view when they are not relevant. They are only shown in the Smart Stack when relevant. The watchOS 26 Design ToolKit in the Apple Design Resources includes a set of templates that you can use to layout your widgets. 3. Is the Wrist Flick gesture available to developers in the same way as Double Tap is? The system uses Wrist Flick to dismiss notifications and incoming calls, silence timers and alarms, or return to the watch face. There is no separate API for the Wrist Flick gesture. Apps that are using XCUIAutomation to make sure their user interface behaves as intended can use the XCUIDeviceHandGesture.flick to automate tests that verify that their app responds appropriately to the Wrist Flick gesture. For apps using automated testing, the XCUIDeviceHandGesture.doubleTap can be also be used to automate testing of the app with the Double Tap gesture. See XCUIDevice.perform(handGesture:) 4. Can HRV measurements be triggered on demand via API in watchOS? Guidelines or processes for enabling energy-intensive biometric sampling on development devices for IRB-approved research? You don’t have direct control on the sampling rate in watchOS. You can use HealthKit (HKQuantityTypeIdentifierHeartRateVariabilitySDNN, to be specific) to query the HRV data, once the system has sampled and persisted the data to HealthKit. If that doesn’t help, we suggest that you file a feedback report with your concrete use case for us to investigate. Specific to IRB-approved research using Apple Watch or its companion iPhone, you might want to look at this FAQ and SensorKit to see if they can be of any help. 5. What is the best advice for someone who is new to making a watchOS app that’s been on iOS and iPadOS? You can start with exploring the system experience features on watchOS, such as notifications, controls, and widgets, and getting familiar with the system spaces, like Smart Stack, watch face, and control center. Knowing the watchOS app design principles and practices is important as well. Design and build apps for WatchOS 10 is a great resource for this topic. SwiftUI is an amazing across-platform framework, and you will use it to create your watchOS app. If you're already using it, great! Keep in mind some watch-only constraints. Comparing to iPhone or iPad, Apple Watch has a limited battery and smaller screen size, which significantly impacts how people use your app and how your app works. 6. Was there any extension this year to the 7 day limit on querying Apple Health data on the watch? There is no change on the limit this year. You can get this official limit at runtime using earliestPermittedSampleDate. There are some exceptions, and so don't be surprised if you see some data types are retained longer. The companion iPhone holds the full set of the health data. If you need to access the health data that has been purged from the Apple Watch, consider doing it with your iOS app, and then passing the result to your watchOS app.

Device Activity monitor extension Not working
anyone has the same problem which is that your device activity extension ain't working even tho all the code work perfectly in the console, I setup it in the right way , tried to make schedule and it did the same exact thing when I tried to create usage threshold. anyone know the reason for this bug? here is my extension code import ManagedSettings import FamilyControls import Foundation import OSLog import UserNotifications class MonitoringExtension: DeviceActivityMonitor { private let defaults = UserDefaults(suiteName: "group.com.William.app") private let logger = Logger(subsystem: "com.William.app", category: "MonitoringExtension") override func eventDidReachThreshold(_ event: DeviceActivityEvent.Name, activity: DeviceActivityName) { let activityRaw = activity.rawValue logger.info("Limite atteinte: \(activityRaw)") scheduleNotification(title: "Limite dépassée", body: "Tu as utilisé trop de temps sur \(activityRaw).") guard let data = defaults?.data(forKey: "\(activityRaw)_selection"), let selection = try? JSONDecoder().decode(FamilyActivitySelection.self, from: data) else { logger.warning("Pas de sélection pour \(activityRaw)") return } let store = ManagedSettingsStore() // ← LE SEUL QUI MARCHE store.shield.applications = selection.applicationTokens if !selection.categoryTokens.isEmpty { store.shield.applicationCategories = .specific(selection.categoryTokens) } logger.info("BLOCAGE ACTIF via ManagedSettingsStore.default") } override func intervalDidEnd(for activity: DeviceActivityName) { super.intervalDidEnd(for: activity) let store = ManagedSettingsStore() store.clearAllSettings() // ← Débloque à minuit logger.info("Restrictions levées à la fin de l'intervalle") } private func scheduleNotification(title: String, body: String) { UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound]) { granted, _ in guard granted else { return } let content = UNMutableNotificationContent() content.title = title content.body = body let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: nil) UNUserNotificationCenter.current().add(request) } } }

CarKeyErrorCode in the CarKey framework
I have a question regarding CarKeyErrorCode in the CarKey framework. I plan to use the following methods in the CarKey framework: CarKeyRemoteControl.start CarKeyRemoteControlSession.vehicleReports CarKeyRemoteControlSession.perform RemoteKeylessEntryAction.ExecutionRequest.results Each of the above methods throws an Error. Are these different from CarKeyErrorCode? Is CarKeyErrorCode only used in CarKeyRemoteControlSessionDelegate.remoteControlSession(_:didInvalidateWithError:)? If methods 1-4 do not return CarKeyErrorCode, what kind of Error do they return? Thank you in advance.

How can I open a GPX file in my app with iOS 26 “Files” app?
Hi, I’m trying to open a GPX file (route.gpx) from the Files app on my iPhone using my app (e.g., Aqua Map). Since the latest iOS update (iOS 26), when I long-press the file and tap “Open with…”, my app does not appear in the list anymore. I’ve checked that my app has the correct permissions for Files and Folders. I’m wondering: Is this a user-side issue (Settings on iPhone)? Or does it require developer-side changes in the app (Info.plist / UTI declarations) to make .gpx files appear in “Open with…” or “Share” menus? What is the proper way to make my app appear as an option to open GPX files in Files.app on iOS 26? Thanks in advance!

Can I use combine on a property in an @Observable class?
As the title suggests, I have a class marked with @Observable. Within the class I have multiple var's. When one of my var's changes (formation), I want to run an updateOrCreateContent(). I had thought I could just do this with a bit of combine, but I'm struggling to get it working... The code below has a compile error at $formation When I mark formation @Published, it generates a different compile error: "Invalid redeclaration of synthesized property '_formation'" any help appreciated thanks class LayoutModel { var players: [Player] = [] var formation: Formation = .f433 var cancellables = Set<AnyCancellable>() init(players: [Player], formation: Formation) { self.players = players self.formation = formation updateOrCreateContent() $formation.sink(receiveValue: { _ in self.updateOrCreateContent() }) .store(in: &cancellables) }
