Message Filter Extension won't use Basic Auth
I am trying to set up a message filter extension that will use shared web credentials for basic auth when calling to its ILMessageFilterExtensionNetworkURL. I have associated domains set up for both "messagefilter:" and "webcredentials:" and the message filter IS correctly calling the ILMessageFilterExtensionNetworkURL with each message - so that part is working. As detailed here, I have set up Shared Web Credentials and my view controller is using SecAddSharedWebCredential() to save the creds to the correct domain. Using Authorization services, the creds are auto-filled into my app's login screen. When I go under Settings > Passwords, I see the creds are saved and they are the correct creds to the corrent website that matches ILMessageFilterExtensionNetworkURL. Regardless of all of this, the deferQueryRequestToNetwork() refuses to use the creds and implement Basic Auth in its URL call. It makes the call to the correct URL, it just won't use the Shared Web Creds for basic auth. Any help would be greatly appreciated.

Title: DNS Proxy Not Capturing Traffic When Public DNS Is Set in WiFi Settings
I'm working on a Network Extension using NEDNSProxyProvider to inspect DNS traffic. However, I've run into a couple of issues: DNS Proxy is not capturing traffic when a public DNS (like 8.8.8.8 or 1.1.1.1) is manually configured in the WiFi settings. It seems like the system bypasses the proxy in this case. Is this expected behavior? Is there a way to force DNS traffic through the proxy even if a public DNS is set? Using DNS Proxy and DNS Settings simultaneously doesn't work. Is there a known limitation or a correct way to combine these? How to set DNS or DNSSettings using DNSProxy? import NetworkExtension import SystemExtensions import SwiftUI protocol DNSProxyManagerDelegate { func managerStateDidChange(_ manager: DNSProxyManager) } class DNSProxyManager: NSObject { private let manager = NEDNSProxyManager.shared() var delegate: DNSProxyManagerDelegate? private(set) var isEnabled: Bool = false { didSet { delegate?.managerStateDidChange(self) } } var completion: (() -> Void)? override init() { super.init() self.load() } func toggle() { isEnabled ? disable() : start() } private func start() { let request = OSSystemExtensionRequest .activationRequest(forExtensionWithIdentifier: Constants.extensionBundleID, queue: DispatchQueue.main) request.delegate = self OSSystemExtensionManager.shared.submitRequest(request) log.info("Submitted extension activation request") } private func enable() { update { self.manager.localizedDescription = "DNS Proxy" let proto = NEDNSProxyProviderProtocol() proto.providerBundleIdentifier = Constants.extensionBundleID self.manager.providerProtocol = proto self.manager.isEnabled = true } } private func disable() { update { self.manager.isEnabled = false } } private func remove() { update { self.manager.removeFromPreferences { _ in self.isEnabled = self.manager.isEnabled } } } private func update(_ body: @escaping () -> Void) { self.manager.loadFromPreferences { (error) in if let error = error { log.error("Failed to load DNS manager: \(error)") return } self.manager.saveToPreferences { (error) in if let error = error { return } log.info("Saved DNS manager") self.isEnabled = self.manager.isEnabled } } } private func load() { manager.loadFromPreferences { error in guard error == nil else { return } self.isEnabled = self.manager.isEnabled } } } extension DNSProxyManager: OSSystemExtensionRequestDelegate { func requestNeedsUserApproval(_ request: OSSystemExtensionRequest) { log.info("Extension activation request needs user approval") } func request(_ request: OSSystemExtensionRequest, didFailWithError error: Error) { log.error("Extension activation request failed: \(error)") } func request(_ request: OSSystemExtensionRequest, foundProperties properties: [OSSystemExtensionProperties]) { log.info("Extension activation request found properties: \(properties)") } func request(_ request: OSSystemExtensionRequest, didFinishWithResult result: OSSystemExtensionRequest.Result) { guard result == .completed else { log.error("Unexpected result \(result.description) for system extension request") return } log.info("Extension activation request did finish with result: \(result.description)") enable() } func request(_ request: OSSystemExtensionRequest, actionForReplacingExtension existing: OSSystemExtensionProperties, withExtension ext: OSSystemExtensionProperties) -> OSSystemExtensionRequest.ReplacementAction { log.info("Existing extension willt be replaced: \(existing.bundleIdentifier) -> \(ext.bundleIdentifier)") return .replace } } import NetworkExtension class DNSProxyProvider: NEDNSProxyProvider { var handlers: [String: FlowHandler] = [:] var isReady = false let queue = DispatchQueue(label: "DNSProxyProvider") override func startProxy(options:[String: Any]? = nil, completionHandler: @escaping (Error?) -> Void) { completionHandler(nil) } override func stopProxy(with reason: NEProviderStopReason, completionHandler: @escaping () -> Void) { completionHandler() } override func handleNewUDPFlow(_ flow: NEAppProxyUDPFlow, initialRemoteEndpoint remoteEndpoint: NWEndpoint) -> Bool { let id = shortUUID() handlers[id] = FlowHandler(flow: flow, remoteEndpoint: remoteEndpoint, id: id, delegate: self) return true } override func handleNewFlow(_ flow: NEAppProxyFlow) -> Bool { return false } } class FlowHandler { let id: String let flow: NEAppProxyUDPFlow let remoteEndpoint: NWHostEndpoint let delegate: FlowHandlerDelegate private var connections: [String: RemoteConnection] = [:] private var pendingPacketsByDomain: [String: [(packet: Data, endpoint: NWEndpoint, uniqueID: String, timestamp: Date)]] = [:] private let packetQueue = DispatchQueue(label: "com.flowhandler.packetQueue") init(flow: NEAppProxyUDPFlow, remoteEndpoint: NWEndpoint, id: String, delegate: FlowHandlerDelegate) { log.info("Flow received for \(id) flow: \(String(describing: flow))") self.flow = flow self.remoteEndpoint = remoteEndpoint as!

Bluetooth 5 Coded PHY (Long Range) removed in iOS 14
I am pretty sure iOS 13.4 (beta and later) did support Coded PHY (Long Range). Tested devices are iPhone SE2 and iPhone 11 Pro. However, it seems iOS 14 removed the support of Coded PHY, accidentally or on purpose, I don't know? The same PHY update request returns "1M PHY" in iOS 14, but "Coded PHY" in iOS 13 (13.4 beta and later). Anyone knows why? Samson

URLSessionWebSocketTask reports closeCode as invalid when state is completed
I am using a URLSessionWebSocketTask. When trying to receive messages while the app is backgrounded, the receive() method fails with an NSError where the domain is NSPOSIXErrorDomain and the code is ECONNABORTED. That behavior is good. However, when this happens, the URLSessionWebSocketTask reports a closeCode of invalid, which is supposed to denote that the connection is still open. However, the connection state property is reporting completed. I feel that the closeCode property should be reporting something like abnormalClosure in this case. Either way, this seems like a bug or the documentation is incorrect.

'openAppWhenRun' property causing AppIntentsExtension to fail
I have added an "App Intents Extension" target to my main application in macOS. This generated the below two files: TWAppIntent.swift import AppIntents struct TWAppIntent: AppIntent { static var title: LocalizedStringResource = "TWAppIntentExtension" static var parameterSummary: some ParameterSummary { Summary("Get information on \(\.$TWType)") } //launch app on running action static var openAppWhenRun: Bool = true // we can have multiple parameter of diff types @Parameter(title: "TWType") var TWType: String func perform() async throws -> some IntentResult & ReturnsValue<String> & ProvidesDialog { return .result(value: TWType, dialog: "Logged break.") } } TWAppIntentExtension.swift import AppIntents @main struct TWAppIntentExtension: AppIntentsExtension { } I m able to build the extension target and I my intent action is available in the shortcuts app. However, on launching a shortcut with the above created intent action. I m getting the below popups: I have identified what is causing this error. Setting the openAppWhenRun to true is causing this error. I don't get this when it is set to false. This property is supposed to launch the application, but can someone help me understand why is it happening? This is only causing the error when using this property for AppIntent Extension and not for In app handling for the AppIntent. Can we not launch our application from AppIntent extension?

StoreKit 2 AppTransaction failing
We have had a small number of users of our mac app complaining that the app suddenly can't detect their subscription or previous purchase history. These users are not new, and have been using the app successfully for some time. In the app we do this using the following (very standard) code at app startup: let result: VerificationResult<AppTransaction> = try await AppTransaction.shared For those users experiencing the failure, the result is coming back as unverified. So far we've been unable to find the cause or a solution, but it seems to have become worse with the release of macOS 15.4. We've tried resetting, rebooting and reinstalling the app. It's worth adding the (probably obvious) that it's impossible to test or fault-find with this, because we can't replicate the issue in a development environment. Any suggestions gratefully received.

Error Domain=PKPassKitErrorDomain Code=2
This error occurs in Apple Pay Wallet In-App Provisioning Flow for Credit / Debit Cards When the data received from the PNO (Visa) is passed to PKAddPaymentPassRequest this error is seen in addPaymentPassViewController, in the finalize stage. Docs provide no clue as to what could be wrong. iOS 18.2.1 XCode 15.2 Error description mentions "unsupportedVersionError" Is the pass version not supported? Is the wallet version not supported? Is it an app implementation error or error in the data received from the PNO?

AlarmKit Volume and Volume Buttons
Excited for AlarmKit! I have found two concerns that I cannot find answers for though. The volume of my alarms seems to be very quite relative to the full volume capability of the device. For example, if I turn the volume all the way up and play the audio file, the sound is very loud. However then, if I set the alarm using alarm kit with the same audio, the track played during the alerting phase is not that loud. I am afraid that it will not be loud enough in real life. Will there be future support to set the volume level of the alarm to maximum settings? When I press the volume buttons (with the app open) during an active alarm, the audio stops, but the alarm manager does not clear these events. The alarm manager does clear the alarm event if the alarm is stopped through a live activity.

HKObserverQuery stops delivering updates in background on watchOS 26
Hello, I’m building a health-related app for both watchOS and iOS, which needs to monitor certain health data (e.g., heart rate, active energy). Before updating to watchOS 26, the queries worked reliably without any issues. However, after adapting to watchOS 26, some users have reported that health data updates stop being delivered. What I’ve observed: HKObserverQuery with enableBackgroundDelivery is set up normally. On WatchOS 26, the query sometimes stops delivering updates entirely after a certain point, and once an update is missed, it may stop delivering further updates completely. Restarting the Apple Watch temporarily restores delivery, but the problem reoccurs after some time. This makes background health data monitoring unreliable for my app. Here’s a simplified version of the code we are using: guard let heartType = HKObjectType.quantityType(forIdentifier: .heartRate) else { return } let query = HKObserverQuery(sampleType: heartType, predicate: nil) { query, completionHandler, error in if let error = error { logEvent("Observer error: \(error.localizedDescription)") return } logEvent("Heart rate changed") MyNotificationManager.shared.sendNotification() // Send a local notification completionHandler() } healthStore.execute(query) healthStore.enableBackgroundDelivery(for: heartType, frequency: .hourly) { success, error in if success { logEvent("Background heart rate delivery enabled") } else { logEvent("Failed to enable background heart rate delivery: \(error?.localizedDescription ?? "Unknown error")") } } Could you please clarify: Is this a known issue with HKObserverQuery and enableBackgroundDelivery on watchOS 26? Are there any recommended workarounds or best practices to ensure continuous background delivery of health data? Thank you in advance for your help.

Background location stops with (kCLErrorDomain error 1.) but permission was granted
We are currently experiencing a very interesting issue when accessing the location in the background with CLLocationManager. The user has given our app the "whenInUse" permission for locations and in most cases the app provides location updates even when it's in the background. However, when we started to use other navigation apps in the foreground we saw that the func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) method was called with (kCLErrorDomain error 1.). The user hasn't changed the location permission and we saw that locations were delivered once the user opened the app again. I don't see anything in the documentation explaining this issue, but I chatted with other developers that confirm that specific behavior. Am I missing something here?

URLSession downloadTask(with:) TimeOut Error NSURLErrorDomain Code=-1001, _kCFStreamErrorCodeKey=-2103
I have been battling this intermittent error for some time. It is generally random and has been difficult to reproduce until yesterday when I stumbled across a way to reproduce it each time. I can cause the code to throw this error: Task <70E3909F-8C30-4F34-A8B0-4AF3B41DD81B>.<1> finished with error [-1001] Error Domain=NSURLErrorDomain Code=-1001 "The request timed out."

URLSession errors Random timed out error on app start Because I was able to reproduce it, I have been able to get the following logs: Console Logs.txt Last bit of information is that I had Network Instruments running, and when this error occurred, I found that the Connection ID was "No Connection" and it appears the request was never actually sent, though it waited the full time out for a backend response. Any help would be appreciated. This data request is being used after sending a certain APNs to update necessary data in the background, and has been the source of many user complaints.

Xcode 16.4 and above build error with Network Extension and WireGuard library
I have added a Network Extension to my iOS project to use the WireGuard library. Everything was working fine up to Xcode 16, but after updating, I’m facing a build issue. The build fails with the following error: No such file or directory: '@rpath/WireGuardNetworkExtensioniOS.debug.dylib' I haven’t explicitly added any .dylib to my project. The Network Extension target builds and runs fine on Xcode 16.

Transaction ID Misassociation in IAP Subscription API
Dear Apple Support Team, Hello! I am currently developing the in-app subscription functionality using Apple IAP API and have encountered a serious technical issue while processing subscription data. I would like to report this issue to you. Issue Description: When calling the subscription API endpoint, the same OriginalTransactionId returns inconsistent results. Specifically, a particular transaction ID (let's call it TransactionId_A) should belong to the subscription order with OriginalTransactionId_A, but it is currently incorrectly associated with OriginalTransactionId_B. This issue severely affects our ability to accurately manage and process subscription data. Here are the relevant log details for your reference: API Endpoint Requested: https://api.storekit.itunes.apple.com/inApps/v1/subscriptions/{TransactionId_A} (Note: The link is a placeholder for the actual API endpoint.) Log Information on February 21, 2025, at 09:40:09: { "AppAccountToken": "{AppAccountToken}", "BundleId": "{BundleId}", "Currency": "CNY", "Environment": "Production", "ExpiresDate": {ExpiresDate}, "InAppOwnershipType": "PURCHASED", "IsUpgraded": false, "OfferDiscountType": "", "OfferIdentifier": "", "OfferType": 0, "OriginalPurchaseDate": {OriginalPurchaseDate}, "OriginalTransactionId": "{OriginalTransactionId_A}", "Price": {Price}, "ProductId": "{ProductId}", "PurchaseDate": {PurchaseDate}, "Quantity": 1, "RevocationDate": 0, "RevocationReason": 0, "SignedDate": {SignedDate}, "Storefront": "CHN", "StorefrontId": {StorefrontId}, "SubscriptionGroupIdentifier": "{SubscriptionGroupIdentifier}", "TransactionId": "{TransactionId_A}", "TransactionReason": "PURCHASE", "Type": "Auto-Renewable Subscription", "WebOrderLineItemId": "{WebOrderLineItemId}" } Log Information on March 21, 2025, at 09:38:49: { "AppAccountToken": "{AppAccountToken}", "BundleId": "{BundleId}", "Currency": "CNY", "Environment": "Production", "ExpiresDate": {ExpiresDate}, "InAppOwnershipType": "PURCHASED", "IsUpgraded": false, "OfferDiscountType": "", "OfferIdentifier": "", "OfferType": 0, "OriginalPurchaseDate": {OriginalPurchaseDate}, "OriginalTransactionId": "{OriginalTransactionId_B}", "Price": {Price}, "ProductId": "{ProductId}", "PurchaseDate": {PurchaseDate}, "Quantity": 1, "RevocationDate": 0, "RevocationReason": 0, "SignedDate": {SignedDate}, "Storefront": "CHN", "StorefrontId": {StorefrontId}, "SubscriptionGroupIdentifier": "{SubscriptionGroupIdentifier}", "TransactionId": "{TransactionId_A}", "TransactionReason": "PURCHASE", "Type": "Auto-Renewable Subscription", "WebOrderLineItemId": "{WebOrderLineItemId}" } From the above logs, it is evident that the same transaction (TransactionId_A) returns different OriginalTransactionId values at different times, which is clearly not expected and severely impacts our ability to correctly process and manage subscription data. I hope you can address and investigate this issue as soon as possible. If you need any further information or assistance, please feel free to contact me. Thank you for your support! Best regards!

Trying to make the URL filter sample work
Hello, I've been experimenting with the new NEURLFilter API and so far the results are kind of strange. SimpleURLFilter sample contains a bloom filter that seems to be built from this dataset in pir-service-example. I was able to run SimpleURLFilter sample and configure it to use PIRService from the example repo. I also observed the requests that iOS has been sending: requesting config and then sending /queries request. What I haven't seen is any .deny verdict for any URL. Even when calling NEURLFilter.verdict(for: url) directly I cannot see a .deny verdict. Is there anything wrong with the sample or is there a known issue with NEURLFilter in the current beta (beta 8) that prevents it from working?

[iOS 18 Beta 4] DeviceActivityMonitor extension is more likely to deadlock
Hi there, My app uses all the Screen Time API's with individual FamilyControls authorization. I've been using the API's for over 2 years (since they came out). In iOS 18 Beta (maybe started in Beta 3?), I've been experiencing random issues. I tracked it down to where it seems like DeviceActivityMonitor extension is more likely to deadlock in iOS 18. To reproduce: when DeviceActivityMonitorExtension.intervalDidEnd gets called, IF you call DeviceActivityCenter.startMonitoring for that SAME DeviceActivityName from the DeviceActivityMonitorExtension , the startMonitoring call deadlocks (if I pause debugger, it does not advance past DeviceActivityCenter.startMonitoring). The bug is reported in FB14664238. It also contains a sample project where you can reproduce this. I also note in the comment section that this is not the only way to encounter this problem. My application code (which is a lot more complicated) seems to deadlock on calling DeviceActivityCenter.activities. As a result, there seems to be an "overall trend" where, due to some changes, DeviceActivityMonitor extension is more likely to deadlock. The steps are not reproducible on iOS 17.6. This is built using Xcode 17.4. Thank you! 🙏

In-tunnel networking when `includeAllNetworks` is set.
When setting up a packet tunnel with a profile that has includeAllNetworks set to true, we seemingly cannot send any traffic inside the tunnel using any kind of an API. We've tried using BSD sockets, as we ping a host only reachable within the tunnel to establish whether we have connectivity - this does not work. When using NWConnection from the Network framework and specifying the required interface via virtualInterface from the packet tunnel, the connection state never reaches ready. Our interim solution is to, as ridiculous as it sounds, include a whole userspace networking stack so we can produce valid TCP packets just to send into our own tunnel. We require a TCP connection within our own tunnel to do some configuration during tunnel setup. Is there no better solution?

APNs Auth Key download error after revoking old key — “already downloaded” for new key
I created an APNs Auth Key in the Apple Developer portal and downloaded it successfully once. Later, due to some issues, I revoked that key. After that, I created a new APNs Auth Key. The download button appears, but when I click it, I get the message: "Auth Key can only be downloaded once. This auth key has already been downloaded." This is incorrect because: The key is newly created in my account. I have tried multiple browsers (Safari, Chrome), private/incognito mode, and even a different laptop. I have no other active APNs Auth Keys in my account. Without this .p8 file, I cannot configure push notifications for my iOS app (using Firebase Cloud Messaging). This is blocking my production release. Has anyone else experienced this? Is there a way to reset or force a fresh APNs Auth Key when this happens?

Disable URLSession auto retry policy
We are developing an iOS application that is interacting with HTTP APIs that requires us to put a unique UUID (a nonce) as an header on every request (obviously there's more than that, but that's irrilevant to the question here). If the same nonce is sent on two subsequent requests the server returns a 412 error. We should avoid generating this kind of errors as, if repeated, they may be flagged as a malicious activity by the HTTP APIs. We are using URLSession.shared.dataTaskPublisher(for: request) to call the HTTP APIs with request being generated with the unique nonce as an header. On our field tests we are seeing a few cases of the same HTTP request (same nonce) being repeated a few seconds on after the other. Our code has some retry logic only on 401 errors, but that involves a token refresh, and this is not what we are seeing from logs. We were able to replicate this behaviour on our own device using Network Link Conditioner with very bad performance, with XCode's Network inspector attached we can be certain that two HTTP requests with identical headers are actually made automatically, the first request has an "End Reason" of "Retry", the second is "Success" with Status 412. Our questions are: can we disable this behaviour? can we provide a new request for the retry (so that we can update headers)? Thanks, Francesco

Custom HCE payment UI
We are currently developing a wallet solution that uses the iOS EEA HCE API. During the development of our solution we have been unable to identify how we can opt out of using the native HCE payment modal screen or biometric authentication UI so that we can customise the experience to align with our overall customer experience. The only available customisation is a label below the title of the screen which does not meet our needs. Please can you advise how we can opt out of using the native HCE payment modal screen. If it is not possible to opt out of using the native HCE payment modal screen, please can you provide the rationale for this given the Digital Marketing Act interoperability guidelines and EU Commitments in case AT.40452.
