Hello, We've been working on an app that uses the new NEUrlFilter API and we've got a question. Currently, the system is designed with the assumption that a single app == usecase == single remote database. But what if we would like to give the user the ability to use different blocklists? For example, the user may want to: Block scam domains Block tracking domains Block adult domains Or any composition of these 3 What should we do to give the user this option? It seems that we could differentiate different databases by using different PIR service hostnames, but that would also mean that we'll have to send several requests for the same usecase but with different PIR service hostnames (and they'll all share the same app bundle ID). Will these requests be accepted then? If not, is there an alternative? PS: By sending a request I mean submitting this form

I'm working with Apple's SimpleURLFilter sample project and consistently encountering an error when trying to implement the URL filter. Here are the details: Setup: Downloaded the official SimpleURLFilter sample project from Apple Set the developer team for both targets (main app and extension) Built and ran the PIR server on my laptop using Docker as per the sample instructions Built the iOS project on my iPhone running iOS 26.0.1 Server is accessible at my Mac's IP address on port 8080 Configuration: PIR Server URL: http://[my-mac-ip]:8080 Authentication Token: AAAA (as specified in service-config.json) Privacy Pass Issuer URL: (left empty) Fail Closed: enabled Code Changes: The only modifications I made were: Updated bundle identifiers to include my team identifier Updated PIR server's service-config.json to match: com.example.apple-samplecode.SimpleURLFilter[TEAM_ID].url.filtering Modified URLFilterControlProvider.swift: Added existingPrefilterTag: String? parameter to fetchPrefilter() method Added tag: "bloom_filter" parameter to NEURLFilterPrefilter initializer Issue: After configuring the filter and entering my passcode in Settings, I consistently see: Received filter status change: <FilterStatus: 'starting'> Received filter status change: <FilterStatus: 'stopped' errorMessage: 'The operation couldn't be completed. (NetworkExtension.NEURLFilterManager.Error error 9.)'> Questions: What does NEURLFilterManager.Error error 9 specifically indicate? Could the URLFilterControlProvider modifications be causing this issue? Are there debugging steps to get more detailed error information? Any guidance would be appreciated!

Summary NetworkConnection<WebSocket> in iOS 26 Network framework throws POSIXErrorCode(rawValue: 22): Invalid argument when receiving WebSocket ping (opcode 9) or pong (opcode 10) control frames. This prevents proper WebSocket keep-alive functionality. Environment iOS 26.0 (Simulator) macOS 26.1 Xcode 26.0 Note: This issue was initially discovered on iOS 26 Simulator. The same behavior was confirmed on macOS 26, suggesting a shared bug in the Network framework. The attached sample code is for macOS for easier reproduction. Description When using the new NetworkConnection<WebSocket> API introduced in iOS 26 or macOS 26, the receive() method throws EINVAL error whenever a ping or pong control frame is received from the server. This is a critical issue because: WebSocket servers commonly send ping frames to keep connections alive Clients send ping frames to verify connection health The receive callback never receives the ping/pong frame - the error occurs before the frame reaches user code Steps to Reproduce Create a WebSocket connection to any server that supports ping/pong (e.g., wss://echo.websocket.org): import Foundation import Network // MARK: - WebSocket Ping/Pong EINVAL Bug Reproduction // This sample demonstrates that NetworkConnection<WebSocket> throws EINVAL // when receiving ping or pong control frames. @main struct WebSocketPingPongBug { static func main() async { print("=== WebSocket Ping/Pong EINVAL Bug Reproduction ===\n") do { try await testPingPong() } catch { print("Test failed with error: \(error)") } } static func testPingPong() async throws { let host = "echo.websocket.org" let port: UInt16 = 443 print("Connecting to wss://\(host)...") let endpoint = NWEndpoint.hostPort( host: NWEndpoint.Host(host), port: NWEndpoint.Port(rawValue: port)! ) try await withNetworkConnection(to: endpoint, using: { WebSocket { TLS { TCP() } } }) { connection in print("Connected!\n") // Start receive loop in background let receiveTask = Task { var messageCount = 0 while !Task.isCancelled { do { let (data, metadata) = try await connection.receive() messageCount += 1 print("[\(messageCount)] Received frame - opcode: \(metadata.opcode)") if let text = String(data: data, encoding: .utf8) { print("[\(messageCount)] Content: \(text)") } else { print("[\(messageCount)] Binary data: \(data.count) bytes") } } catch let error as NWError { if case .posix(let code) = error, code == .EINVAL { print("❌ EINVAL error occurred! (POSIXErrorCode 22: Invalid argument)") print(" This is the bug - ping/pong frame caused EINVAL") // Continue to demonstrate workaround continue } print("Receive error: \(error)") break } catch { print("Receive error: \(error)") break } } } // Wait for initial message from server try await Task.sleep(for: .seconds(2)) // Test 1: Send text message (should work) print("\n--- Test 1: Sending text message ---") try await connection.send("Hello, WebSocket!") print("✅ Text message sent") try await Task.sleep(for: .seconds(1)) // Test 2: Send ping (pong response will cause EINVAL) print("\n--- Test 2: Sending ping frame ---") print("Expecting EINVAL when pong is received...") let pingMetadata = NWProtocolWebSocket.Metadata(opcode: .ping) try await connection.ping(Data()) { pingMetadata } print("✅ Ping sent, waiting for pong...") // Wait for pong response try await Task.sleep(for: .seconds(2)) // Cleanup receiveTask.cancel() print("\n=== Test Complete ===") print("If you saw 'EINVAL error occurred!' above, the bug is reproduced.") } } } The receive() call fails with error when pong arrives: ❌ EINVAL error occurred! (POSIXErrorCode 22: Invalid argument) Test Results Scenario Result Send/receive text (opcode 1) ✅ OK Client sends ping, receives pong ❌ EINVAL on pong receive Expected Behavior The receive() method should successfully return ping and pong frames, or at minimum, handle them internally without throwing an error. The autoReplyPing option should allow automatic pong responses without disrupting the receive loop. Actual Behavior When a ping or pong control frame is received: The receive() method throws NWError.posix(.EINVAL) The frame never reaches user code (no opcode check is possible) The connection remains valid, but the receive loop is interrupted Workaround Catch the EINVAL error and restart the receive loop: while !Task.isCancelled { do { let received = try await connection.receive() // Process message } catch let error as NWError { if case .posix(let code) = error, code == .EINVAL { // Control frame caused EINVAL, continue receiving continue } throw error } } This workaround allows continued operation but: Cannot distinguish between ping-related EINVAL and other EINVAL errors Cannot access the ping/pong frame content Cannot implement custom ping/pong handling Impact WebSocket connections to servers that send periodic pings will experience repeated EINVAL errors Applications must implement workarounds that may mask other legitimate errors Additional Information Packet capture confirms ping/pong frames are correctly transmitted at the network level The error occurs in the Network framework's internal processing, before reaching user code

We have a content filter system extension as part of our macOS app. The filter normally works correctly, activation and deactivation works as expected but occasionally we see an issue when the content filter is activated. When this issues occurs, the filter activation appears to behave correctly, no errors are reported. Using "systemextensionsctl list" we see the filter is labelled as "[activated enabled]". However, the installed content filter executable does not run. We have seen this issue on macOS 15.3 and later and on the beta macOS 26.1 RC. It happens only occasionally but when it does there is no indication as to why the executable is not running. There are no crash logs or errors in launchd logs. Both rebooting and deactivating/activating the filter do not resolve the issue. The only fix appears to be completely uninstalling the app (including content filter) and reinstalling. I have raised a FB ticket, FB20866080. Does anyone have any idea what could cause this?

The environment: macOS 12.0 ~ 15.6 A NetworkExtension NEFilterDataProvider configured with filterSockets = YES, filterPackets = NO, and it doesn't actually block any network connection. QQMusic (download: https://y.qq.com/n/ryqq/download_detail/mac?ADTAG=YQQ) is constantly playing. Any of the following operations can reproduce the issue: Kill the NetworkExtension process and then restarted by the system. Disable the NEFilterDataProvider, and then enable it. When this problem occurs, there are two different phenomena on the NetworkExtension process: It is zombie, or is in high CPU state (100%). When the NetworkExtension process is zombie, obviously, the new network connections will enter it, and they can't be disposed by the old zombie process, so the network is disconnected. Spindump-qqmusic-ne-zombie When the NetworkExtension process is in high CPU state, its thread DispatchQueue "NEFilterExtensionProviderContext queue" is blocked in the kernel when calling close. Spindump-qqmusic-ne-cpuhigh In most cases, the network will recover after stopping QQ Music, that is the suspended zombie NetworkExtension process will exist or the cpu of it return to normal. To reproduce the issue in a simple environment, I have tried many ways to simulate the network behavior of QQMusic, but all failed. It seems that this issue is caused by UDP traffic of QQMusic, because everything is ok after blocking the UDP connections of QQMusic (the music is still playing at this time) in the NEFilterDataProvider.

When I try to implement the new Background Task options in the same way as they show in the WWDC video (on watchOS) likes this: let config = URLSessionConfiguration.background(withIdentifier: "SESSION_ID") config.sessionSendsLaunchEvents = true let session = URLSession(configuration: config) let response = await withTaskCancellationHandler {       try? await session.data(for: request) } onCancel: {       let task = session.downloadTask(with: request))       task.resume() } I'm receiving the following error: Terminating app due to uncaught exception 'NSGenericException', reason: 'Completion handler blocks are not supported in background sessions. Use a delegate instead.' Did I forget something?

Hi all, We've been exploring the capabilities of the Network.framework for peer-to-peer communication and have run into some behavior that we haven't been able to fully explain with the existing documentation. In our tests, we’re working with 12 iOS devices, all disconnected from Wi-Fi to force communication over Apple Wireless Direct Link (AWDL). While using the Network.framework to create peer-to-peer connections, we observed that the number of connected peers never exceeded 8, despite all 12 devices being active and configured identically. Some questions we’re hoping to get clarification or discussion on: Is there a known upper limit to the number of peer-to-peer connections supported via AWDL? Are there conditions under which the framework or system limits or throttles visible peers? Does AWDL behavior vary by hardware model, iOS version, or backgrounding state of the app? Is there any official documentation or guidance around peer discovery or connection limits when using NWBrowser and NWConnection in a peer-to-peer context? We’d appreciate any insights from the Apple engineering team or other developers who have worked with larger peer groups using Network.framework in peer-to-peer mode.

I have been playing around with the new URL Filtering API. I have successfully installed and configured the sample code, Installed the example app to my iPhone, and am also running the PIR server locally on my Mac. In my input.txtpb file, I simply have 2 endpoints: rows: [{ keyword: "instagram.com", value: "1" }, { keyword: "youtube.com/shorts", value: "1" }] Neither of these are blocked when I attempt to load them from either a browser, or their dedicated apps. Are there any debugging tips I should know about? Additionally, I have also noticed a few times I have left the filter running on my phone, after leaving my LAN (where the PIR server is running), suddenly throughout the day I'm having random, completely unrelated endpoints blocked on my phone. I thought this API was never supposed to produce false positives (without calling back to the PIR server for confirmation).

Hello, we are developing hardware that needs to connect to an iPhone via Wi-Fi to send requests to a server. On Android, we have managed to create a programmatic local hotspot within the app to facilitate connection and improve the user experience. On iOS, however, Personal Hotspot must be manually enabled from the system settings, and the user must manually enter the SSID and password, which significantly degrades the UX. My questions are: Is there a workaround, unofficial method, or private API to generate a local hotspot from an app on iOS, similar to what can be done on Android? Is there an alternative within the MFi program or through specific frameworks to facilitate a quick and automatic connection between the hardware and the iPhone without relying on the manual Personal Hotspot? Are there any best practices for improving the local Wi-Fi connection experience between an accessory and an iPhone in the absence of hotspot controls? I would appreciate any guidance, experience, or resources that would help me better understand the feasible options in iOS for scenarios where fast and direct communication between hardware and mobile devices via Wi-Fi is required.

We use as content filter in our app to monitor flows, we gather data about the flow and block flows deemed suspicious. Our content filter is activated/deactivated by a UI app but the flows are reported via XPC to a separate daemon process for analysis. As of macOS 15, we are seeing cases where flows are missing or flows are not received at all by the content filter. The behaviour is not consistent, some devices seem to receive flows normally but others don't. It appears Intel devices are much less prone to showing the problem, whereas Arm devices routinely exhibit missing flows. On macOS 14 or earlier, there is no sign of missing flows. Testing on earlier beta versions of macOS 15 did not appear to show the problem, however I can't rule out if issue was present but it wasn't spotted. Experimenting with simple examples of using a content filter (e.g. QNE2FilterMac) does not appear to reproduce the issue. Questions, What has changed between macOS 14 and 15 that could be the cause of the lack of flows? Is our approach to using an app activated content filter reporting to a daemon connected via XPC unsupported?

Hello, I have been playing around the the SimpleURLFilter sample code. I keep getting this error upon installed the filter profile on the device: mapError unexpected error domain NEVPNConnectionErrorDomainPlugin code 7 which then causes this error: Received filter status change: <FilterStatus: 'stopped' errorMessage: 'The operation couldn’t be completed.

This problem doesn’t appear to relate to the app as everything worked when using http (although an https setup issue may still be the problem). The problem appears to relate to the SSL server certificate on the Ubuntu server and the fact that apple does not accept that it is secure. However I have no problem with the equivalent Android app or web browser connections to the same rest API web services. There are numerous posts on these problems on Apple and other Forums, but none have helped me successfully address the issue. I ran an SSL server test on https://www.ssllabs.com/ssltest/ which gives ratings for SSL sites. The test gave an A rating although a number of minor issues were shown that may be crucial to the iOS failure. Some Sectigo certificates said self signed, which I couldn't understand.

We’ve noticed an issue where after running a network extension, if the phone’s language is changed the Locale.preferredLanguages array is not updated and still returns the old array. It only returns the updated array when the app is reinstalled or the phone is restarted. This is unlike the app itself where using the same Locale.preferredLanguages API immediately returns the updated array. We think this issue is also the cause of notifications that are sent by the network extension being in the previous language as long as the app isn’t reinstalled or the phone is restarted, despite our Localizable file having localised strings for the new language. Feedback ID: FB20086051 The feedback report includes a sample project with steps on how to reproduce the issue.

Our product (rockhawk.ca) uses the Multipeer Connectivity framework for peer-to-peer communication between multiple iOS/iPadOS devices. My understanding is that MC framework communicates via three methods: 1) infrastructure wifi (i.e. multiple iOS/iPadOS devices are connected to the same wifi network), 2) peer-to-peer wifi, or 3) Bluetooth. In my experience, I don't believe I've seen MC use Bluetooth. With wifi turned off on the devices, and Bluetooth turned on, no connection is established. With wifi on and Bluetooth off, MC works and I presume either infrastructure wifi (if available) or peer-to-peer wifi are used. I'm trying to overcome two issues: Over time (since iOS 9.x), the radio transmit strength for MC over peer-to-peer wifi has decreased to the point that range is unacceptable for our use case. We need at least 150 feet range. We would like to extend this support to watchOS and the MC framework is not available. Regarding #1, I'd like to confirm that if infrastructure wifi is available, MC uses it. If infrastructure wifi is not available, MC uses peer-to-peer wifi. If this is true, then we can assure our customers that if infrastructure wifi is available at the venue, then with all devices connected to it, range will be adequate. If infrastructure wifi is not available at the venue, perhaps a mobile wifi router (battery operated) could be set up, devices connected to it, then range would be adequate. We are about to test this. Reasonable? Can we be assured that if infrastructure wifi is available, MC uses it? Regarding #2, given we are targeting minimum watchOS 7.0, would the available networking APIs and frameworks be adequate to implement our own equivalent of the MC framework so our app on iOS/iPadOS and watchOS devices could communicate? How much work? Where would I start? I'm new to implementing networking but experienced in using the MC framework. I'm assuming that I would write the networking code to use infrastructure wifi to achieve acceptable range. Many thanks! Tim

I have a Vision Pro app, which I intend to use Apple-Hosted Background Assets for some of my videos after watching: https://developer.apple.com/videos/play/wwdc2025/325 I added a Apple-Hosted, Managed extension. New Target -> Background Download -> Apple-Hosted, Managed After creating an Archive, I tried uploading it to TestFlight, it complains about a DTPlatformName error in my Info.plist. So I added the following : <key>DTPlatformName</key> <string>xros</string> With which, I managed to upload the app with the extension to TestFlight. However, when I tried installing the app on TestFlight to Vision Pro, it gives me an error that says the app cannot be verified. Any help or pointers is greatly appreciated. Info.plist Entitlements

Hi, We have an issue (https://github.com/actions/runner-images/issues/10924) raised by a user requesting to add 'local network access' permission for macOS 15 and macOS 15-arm64 image runners. Apple introduced a new LNP policy with macOS Sequoia that is not controlled by TCC or MDM. Could you please guide us on how to add 'local network access' permission for macOS 15 and macOS 15-arm64 image runners? Thanks.

iOS Development environment Xcode 16.4, macOS 15.6.1 (24G90) Run-time configuration: iOS 17.2+ Short Description After having successfully established an NWConnection (either as UDP or TCP), and subsequently receiving the error code: UDP Connection failed: 57 The operation couldn't be completed. (Network.NWError error 57 - Socket is not connected), available Interfaces: [enO] via NWConnection.stateUpdateHandler = { (newState) in ... } while newState == .failed the data connection does not restart by itself once cellular (RF) telephony coverage is established again. Detailed Description Context: my app has a continuous cellular data connection while in use. Either a UDP or a TCP connection is established depending on the user settings. The setup data connection works fine until the data connection gets disconnected by loss of connection to a available cellular phone base station. This disconnection simply occurs in very poor UMTS or GSM cellular phone coverage. This is totally normal behavior in bad reception areas like in mountains with signal loss. STEPS TO REPRODUCE Pre-condition App is running with active data connection. Action iPhone does loss the cellular data connection previously setup. Typically reported as network error code 57. Observed The programmed connection.stateUpdateHandler() is called in network connection state '.failed' (OK). The self-programmed data re-connection includes: a call to self.connection.cancel() a call to self.setupUDPConnection() or self.setupConnection() depending on the user settings to re-establish an operative data connection. However, the iPhone's UMTS/GSM network data (re-)connection state is not properly identified/notified via NWConnection API. There's no further network state notification by means of NWConnection even though the iPhone has recovered a cellular data network. Expected The iPhone or any other means automatically reconnects the interrupted data connection on its own. The connection.stateUpdateHandler() is called at time of the device's networking data connection (RF) recovering, subsequently to a connection state failed with error code 57, as the RF module is continuously (independently from the app) for available telephony networks. QUESTION How to systematically/properly detect a cellular phone data network reconnection readiness in order to causally reinitialize the NWConnection data connection available used in app. Relevant code extract Setup UDP connection (or similarly setup a TCP connection) func setupUDPConnection() { let udp = NWProtocolUDP.Options.init() udp.preferNoChecksum = false let params = NWParameters.init(dtls: nil, udp: udp) params.serviceClass = .responsiveData // service type for medium-delay tolerant, elastic and inelastic flow, bursty, and long-lived connections connection = NWConnection(host: NWEndpoint.Host.name(AppConstant.Web.urlWebSafeSky, nil), port: NWEndpoint.Port(rawValue: AppConstant.Web.urlWebSafeSkyPort)!, using: params) connection.stateUpdateHandler = { (newState) in switch (newState) { case .ready: //print("UDP Socket State: Ready") self.receiveUDPConnection(). // data reception works fine until network loss break case .setup: //print("UDP Socket State: Setup") break case .cancelled: //print("UDP Socket State: Cancelled") break case .preparing: //print("UDP Socket State: Preparing") break case .waiting(let error): Logger.logMessage(message: "UDP Connection waiting: "+error.errorCode.description+" \(error.localizedDescription), available Interfaces: \(self.connection.currentPath!.availableInterfaces.description)", LoggerLevels.Error) break case .failed(let error): Logger.logMessage(message: "UDP Connection failed: "+error.errorCode.description+" \(error.localizedDescription), available Interfaces: \(self.connection.currentPath!.availableInterfaces.description)", LoggerLevels.Error) // data connection retry (expecting network transport layer to be available) self.reConnectionServer() break default: //print("UDP Socket State: Waiting or Failed") break } self.handleStateChange() } connection.start(queue: queue) } Handling of network data connection loss private func reConnectionServer() { self.connection.cancel() // Re Init Connection - Give a little time to network recovery let delayInSec = 30.0. // expecting actually a notification for network data connection availability, instead of a time-triggered retry self.queue.asyncAfter(deadline: .now() + delayInSec) { switch NetworkConnectionType { case 1: self.setupUDPConnection() // UDP break case 2: self.setupConnection() // TCP break default: break } } } Does it necessarily require the use of CoreTelephony class CTTelephonyNetworkInfo or class CTCellularData to get notifications of changes to the user’s cellular service provider?

We have developed a DNS filter based on NEDNSProxyProvider. It works great for a minute, then it stops responding. Our logs indicate that during the outage our extension gets DNS requests and formulates DNS responses that it hands back to the OS, but from outside of our code it is as though our extension is not responding.

This is a major issue. After my iPhone 12 Pro was upgraded to iOS 26 beta 6, Apple's official Wi-Fi Aware Sample APP crashed immediately and couldn't be opened. It just force closes. Has any developer encountered this problem?
