What is the purpose of the `alert` field for live activities payloads?
Does the alert only serve the following purposes: required for start events require for any event that needs to alert the user (with sound or having the live activity show in expanded presentation) while its content DO NOT matter. Only the presence of the field and its attributes matter. The only time its content matter are when the receiving device is an Apple Watch. Is that correct?

Sandbox Testing
Hi, I set up a Sandbox Tester account in my company’s Apple Developer Program and signed in on my iPhone under Settings → App Store → Sandbox Account. When I go to Wallet → Add, I only see options for Credit or Debit Card or Travel Card. The option to add an Apple Pay Sandbox Card is missing, and when I try entering the test card numbers from Apple’s documentation (developer.apple.com/apple-pay/sandbox-testing), the card is not valid. Has anyone experienced this and found a solution? Thanks! PS: I can't post this to Wallet Category, I keep getting error that it contains sensitive text.

[Core Bluetooth] The Application which is acting as a CBCentral should automatically connect back with the CBPeripheral in case user has turned OFF the peripheral Device and turned ON the peripheral Device again
Application has specified the bluetooth-central background mode. Peripheral Device(BLE) is connected to the iPhone. Application will initiate a request 'retrieveConnectedPeripheralsWithServices' along with list of services to scan for. Application will receive a list of peripherals connected to the system whose service UUID's match. From the list of peripherals, application will initiate a request 'connectPeripheral' with the interested peripheral along with the option set to 'CBConnectPeripheralOptionEnableAutoReconnect'. This option is available from iOS 17+. CBConnectPeripheralOptionEnableAutoReconnect - This option will help in reconnect back to peripheral when peripheral becomes available. (Turn OFF and Turn ON) How do we achieve the same thing in earlier IOS version

Set the icon displayed in the battery widget
Hi all, In InfiniTime, somebody finally implemented ANCS which forced iOS to encrypt the ble connection. As a result, my PineTime appears in the battery widget. Unfortunately, I only get a Bluetooth logo as the icon. Ideally it would be a smartwatch glyph. The GAP appearance value is being set to 0xC2 (smartwatch) Note: I've used CMF watches in the past, and they display with a smartwatch icon Any thoughts?

BGTaskScheduler fails to match unique identifiers to a registered wildcard handler for BGContinuedProcessingTask
Testing Environment: iOS Version: 26.0 Beta 7 Xcode Version: 17.0 Beta 6 Device: iPhone 16 Pro Description: We are implementing the new BGContinuedProcessingTask API and are using the wildcard identifier notation as described in the official documentation. Our Info.plist is correctly configured with a permitted identifier pattern, such as com.our-bundle.export.*. We then register a single launch handler for this exact wildcard pattern. We are performing this registration within a UIViewController, which is a supported pattern as BGContinuedProcessingTask is explicitly exempt from the "register before applicationDidFinishLaunching" requirement, according to the BGTaskScheduler.h header file. The register method correctly returns true, indicating the registration was successful. However, when we then try to submit a task with a unique identifier that matches this pattern (e.g., com.our-bundle.export.UUID), the BGTaskScheduler.shared.submit() call throws an NSInternalInconsistencyException and terminates the app. The error reason is: 'No launch handler registered for task with identifier com.our-bundle.export.UUID'. This indicates that the system is not correctly matching the specific, unique identifier from the submit call to the registered wildcard pattern handler. This behavior contradicts the official documentation. Steps to Reproduce: Create a new Xcode project. In Signing & Capabilities, add "Background Modes" (with "Background processing" checked) and "Background GPU Access". Add a permitted identifier (e.g., "com.company.test.*") to BGTaskSchedulerPermittedIdentifiers in Info.plist. In a UIViewController's viewDidLoad, register a handler for the wildcard pattern. Check that the register method returns true. Immediately after, try to submit a BGContinuedProcessingTaskRequest with a unique identifier that matches the pattern. Expected Results: The submit call should succeed without crashing, and the task should be scheduled. Actual Results: The app crashes immediately upon calling submit(). The console shows an uncaught NSInternalInconsistencyException with the reason: 'No launch handler registered for task with identifier com.company.test.UUID'. Workaround: The issue can be bypassed if we register a new handler for each unique identifier immediately before submitting a request with that same unique identifier. This strongly suggests the bug is in the system's wildcard pattern-matching logic.

Do I need to maintain CLServiceSession when app relaunches from terminated state due to CLMonitor events?
I'm currently testing the CLMonitor API and have a question about CLServiceSession management. When my app is relaunched from a terminated state in the background due to CLMonitor events, do I still need to create and maintain a CLServiceSession instance? I'm wondering if CLServiceSession is necessary even when I don't need to continuously receive GPS updates through liveUpdates. Since CLMonitor can trigger app launches for region monitoring events without requiring constant location updates, I'm unclear about whether the CLServiceSession is still required in this scenario. Any clarification on the proper implementation would be greatly appreciated. Thanks!

Extremely persistent HealthKit read permissions issue
Overview of Issue My implementation of HealthKit is no longer able to read values due to authorization issues (ex. "HealthKitService: Not authorized to read HKQuantityTypeIdentifierHeight. Status: 0"). I have been through every conceivable debugging step including building a minimal project that just requests HealthKit data and the issue has persisted. I've tried my personal as well as Organizational developer teams. My MacOS and Mac Mini. Simulator and personal device. Rechecked entitlements, reprovisioned certificates. This makes no sense. And I have been unable to find anything similar in the Developer forums or documentation. The problem occurs during the onboarding flow when the app requests HealthKit permissions. Even when the user grants permission in the HealthKit authorization sheet, the authorizationStatus for characteristic data types (like Biological s3x and Date of Birth) and quantity data types (like Height and Weight) consistently returns as .sharingDenied. This prevents the app from pre-filling the user's profile with their HealthKit data, forcing them to enter it manually. The issue seems to be environmental rather than a specific code bug, as it has been reproduced in a minimal test case app and persists despite extensive troubleshooting. Minimal test project: https://github.com/ChristopherJones72521/HealthKitTestApp** STEPS TO REPRODUCE Build app, attempt to sign in. No data is imported into the respective fields in the main app. Console logs confirm. PLATFORM AND VERSION iOS Development environment: Xcode Version 16.4 (16F6), macOS 15.5 (24F74) Run-time configuration: iOS 18.5 Relevant Code Snippets Here are the key pieces of code that illustrate the implementation and the problem: 1. Requesting HealthKit Permissions (HealthKitService.swift) This function is called to request authorization for the required HealthKit data types. The typesToRead and typesToWrite are defined in a centralized HealthKitTypes struct. // HealthKitService.swift func requestPermissions(completion: @escaping (Bool, Error?) -> Void) { guard HKHealthStore.isHealthDataAvailable() else { completion(false, HealthKitError.notAvailable) return } let typesToRead: Set<HKObjectType> = [ HKObjectType.characteristicType(forIdentifier: .dateOfBirth)!, HKObjectType.characteristicType(forIdentifier: .biologicals3x)!, HKObjectType.quantityType(forIdentifier: .height)!, HKObjectType.quantityType(forIdentifier: .bodyMass)! ] let typesToWrite: Set<HKSampleType> = [ HKObjectType.workoutType(), HKObjectType.quantityType(forIdentifier: .activeEnergyBurned)! ] healthStore.requestAuthorization(toShare: typesToWrite, read: typesToRead) { success, error in DispatchQueue.main.async { if let error = error { print("HealthKitService: Error requesting authorization: \(error.localizedDescription)") completion(false, error) } else { print("HealthKitService: Authorization request completed. Success: \(success)") completion(success, nil) } } } } 2. Reading Biological s3x (HealthKitService.swift) This function attempts to read the user's biological s3x. The print statements are included to show the authorization status check, which is where the issue is observed. // HealthKitService.swift func readBiologicals3x() async throws -> HKBiologicals3xObject? { guard HKHealthStore.isHealthDataAvailable() else { throw HealthKitError.notAvailable } let s3xAuthStatus = healthStore.authorizationStatus(for: HKObjectType.characteristicType(forIdentifier: .biologicals3x)!) print("HealthKitService: Auth status for Biological s3x: \(s3xAuthStatus.rawValue)") guard s3xAuthStatus == .sharingAuthorized else { print("HealthKitService: Not authorized to read Biological s3x.") throw HealthKitError.notAuthorized } do { return try healthStore.biologicals3x() } catch { print("HealthKitService: Error executing biologicals3x query: \(error.localizedDescription)") throw HealthKitError.queryFailed(error) } } 3. Calling HealthKit Functions During Onboarding (OnboardingFlowView.swift) This is how the HealthKitService is used within the onboarding flow. The requestHealthKitAndPrefillData function is called after the user signs in, and it attempts to read the data to pre-fill the profile form. // OnboardingFlowView.swift func readHealthKitDataAsync() async { print("Attempting to read HealthKit data async...") // ... (calls to HealthKitService.shared.readDateOfBirth(), readHeight(), etc.) do { if let biologicals3xObject = try await HealthKitService.shared.readBiologicals3x() { if self.selectedGender == nil { switch biologicals3xObject.biologicals3x { case .female: self.selectedGender = .female case .male: self.selectedGender = .male case .other: self.selectedGender = .other default: break } } } } catch { print("OnboardingFlowView: Error reading Biological s3x: (error.localizedDescription)") } print("OnboardingFlowView: Finished HealthKit data processing.") } Console Logs Attempting to read HealthKit data async... HealthKitService: Reading Date of Birth... HealthKitService: Current auth status for DOB (during read attempt): 0 HealthKitService: Not authorized to read Date of Birth. Status: 0 OnboardingFlowView: Error reading Date of Birth: The operation couldn’t be completed. (Strike_Force.HealthKitError error 2.) HealthKitService: Reading Height...

BLE SMP pairing failed due to unspecified reason
Hello, dear Apple engineers. We have recently tried to pair our Android phones and iPhones via BLE SMP, but have encountered a very high probability of pairing failures. Through PacketLogger and Android phone HCI, we have determined that the issue is caused by the iOS side sending an SMP Pairing Failed message during the SMP process. Please help us analyze the reason for this.

[iOS 26] [CallKit] [SDK 26] Application got crashed while App was Inactive
The crash log, an IPS file, indicates a crash occurred at a specific time, with the exception backtrace pointing to _terminateAppIfThereAreUnhandledVoIPPushes. However, cross-reference with the SysDiagnose logs, there is no corresponding process or activity for the application at the reported crash time. The app was not active, nor was it woken up by any event. IPS file and SysDiagnose logs have been attached in the Feedback. Feedback - FB20044587

Apple Pay button not clickable in Safari for some users
Hello, We’re seeing an issue where the Apple Pay button is visible in Safari but not clickable for certain users, while it works normally for others. This happens on our site (https://store-qa2.enphase.com/ ) as well as on other sites for the same affected users. Currently, we display the Apple Pay button based on the following condition: Boolean(window.ApplePaySession) && ApplePaySession.canMakePayments(); For affected users, the button shows up as expected, but it’s not interactive. All users (both affected and unaffected) are on the latest versions of Safari and macOS/iOS. Could someone clarify what additional conditions Safari/Apple Pay requires for the button to be fully functional? And under what circumstances could it be visible but not clickable?

HCE Permission and Background Access for Corporate NFC Integration
Hello, We are currently developing an application that uses the Host-based Card Emulation (HCE) entitlement to enable corporate access functionality. With this entitlement, we have successfully established HCE communication and can interact with our access control systems to unlock doors. Our question is related to improving the user experience: We would like this access functionality to work without requiring the app to be in the foreground, as this adds friction for users during entry. Specifically, we would like to know: Is it possible for our app to coexist with Apple Wallet as the default contactless app, so that: Our app handles NFC interactions for corporate access (e.g., opening doors). Apple Wallet remains the default for payments. If that coexistence is not possible, and our app is set as the default contactless app, Will the system still need to launch our app into the foreground to complete a transaction (e.g., to emulate the NFC card)? Or is there a way to trigger HCE responses in the background (e.g., using a background process or service extension)? Any guidance on how to configure the app for optimal background access behavior, while maintaining compatibility with Wallet, would be greatly appreciated. Thank you in advance.

When referencing the value of an instance variable of type NSString, it may sometimes appear as <__NSMallocBlock__: 0x106452d60>.
When the app launches, it assigns the correct string stored in NSUserDefaults to the instance variable (serverAddress) of type NSString.
Afterwards, when the app transitions to a suspended state and receives a VoIP Push notification approximately 4 hours later, causing the app to enter the background state, referencing the value of serverAddress may result in it showing as &lt;NSMallocBlock: 0x106452d60&gt; even though it hasn't been deallocated. This does not occur every time. The specific class definitions are as follows. @implementation NewPAPEOPLEClient
{
    NSString* serverAddress;
    NSString* apiKey;
    dispatch_semaphore_t lock;
    NSMutableArray* errCallID;
} #define PREF_STR(key)  [[NSUserDefaults standardUserDefaults] stringForKey:(key) The global instance variable (serverAddress) is set with the following value when the application starts: serverAddress = PREF_STR(@"APP_CONTACT_SERVICE_SERVER_ADDRESS") Based on the above, please answer the following questions. (1) If the instance variable's value becomes &lt;NSMallocBlock: 0x106452d60&gt;, does that mean the memory area has been released? (2) Can the memory area of an instance variable be automatically released without being explicitly released?
 Can an instance variable of type NSString that is not autoreleased be automatically released? (3) Please tell me how to prevent the memory area from being automatically released. Will using retain prevent automatic release?
