Bonjour Conformance Test - Multiple Instance in Single Device
We are currently working on a zero-configuration networking compliant device thru avahi-daemon. Our Device want to have multiple Instance name for different services. Example InstanceA._ipps._tcp.local. InstanceA._ipp._tcp.local. InstanceB._ipps._tcp.local. InstanceB._ipp._tcp.local. Will BCT confuse this as multiple device connected in the network and cause it to fail? Does Bonjour only allows only a Single Instance name with multiple services?

Hide OS logs coming out of the Network framework (category: com.apple.network)
I'm establishing a connection with NWListener and NWConnection which is working great. However, if the listener disappears, a lot of logs are appearing: Is there a way to hide these logs? I'm aware of OS_ACTIVITY_MODE=disabled, but that will also hide a lot of other logs. I also know you can hide these using Xcode's filtering. I'm looking for a programmatically way to hide these completely. I'm not interested in seeing these at all, or, at least, I want to be in control. Thanks!

How can user allow a content filter after previously choosing "Don't Allow"?
Our enterprise product uses a content filter, normally customers deploy MDM profiles to authorise and allow the content filter to work. Some customers however do not use these profiles, requiring them to enable the system extension in System Settings and allow the content filter via the popup below. If the user selects "Don't Allow", intentionally or by mistake, there does not appear to be an mechanism for them to change their mind and allow it instead. If the user fails to enable the system extension on the first prompt, there is an option to enable if via System Settings. There doesn't seem to be a similar option if they "Don't Allow" the content filter. How can the user allow a previously denied content filter?

NWBrowser + NWListener + NWConnection
I am seeking assistance with how to properly handle / save / reuse NWConnections when it comes to the NWBrowser vs NWListener. Let me give some context surrounding why I am trying to do what I am. I am building an iOS app that has peer to peer functionality. The design is for a user (for our example the user is Bob) to have N number of devices that have my app installed on it. All these devices are near each other or on the same wifi network. As such I want all the devices to be able to discover each other and automatically connect to each other. For example if Bob had three devices (A, B, C) then A discovers B and C and has a connection to each, B discovers B and C and has a connection to each and finally C discovers A and B and has a connection to each. In the app there is a concept of a leader and a follower. A leader device issues commands to the follower devices. A follower device just waits for commands. For our example device A is the leader and devices B and C are followers. Any follower device can opt to become a leader. So if Bob taps the “become leader” button on device B - device B sends out a message to all the devices it’s connected to telling them it is becoming the new leader. Device B doesn’t need to do anything but device A needs to set itself as a follower. This detail is to show my need to have everyone connected to everyone. Please note that I am using .includePeerToPeer = true in my NWParameters. I am using http/3 and QUIC. I am using P12 identity for TLS1.3. I am successfully able to verify certs in sec_protocal_options_set_verify_block. I am able to establish connections - both from the NWBrowser and from NWListener. My issue is that it’s flaky. I found that I have to put a 3 second delay prior to establishing a connection to a peer found by the NWBrowser. I also opted to not save the incoming connection from NWListener. I only save the connection I created from the peer I found in NWBrowser. For this example there is Device X and Device Y. Device X discovers device Y and connects to it and saves the connection. Device Y discovers device X and connects to it and saves the connection. When things work they work great - I am able to send messages back and forth. Device X uses the saved connection to send a message to device Y and device Y uses the saved connection to send a message to device X. Now here come the questions. Do I save the connection I create from the peer I discovered from the NWBrowser? Do I save the connection I get from my NWListener via newConnectionHandler? And when I save a connection (be it from NWBrowser or NWListener) am I able to reuse it to send data over (ie “i am the new leader command”)? When my NWBrowser discovers a peer, should I be able to build a connection and connect to it immediately? I know if I save the connection I create from the peer I discover I am able to send messages with it. I know if I save the connection from NWListener - I am NOT able to send messages with it — but should I be able to? I have a deterministic algorithm for who makes a connection to who. Each device has an ID - it is a UUID I generate when the app loads - I store it in UserDefaults and the next time I try and fetch it so I’m not generating new UUIDs all the time. I set this deviceID as the name of the NWListener.Service I create. As a result the peer a NWBrowser discovers has the deviceID set as its name. Due to this the NWBrowser is able to determine if it should try and connect to the peer or if it should not because the discovered peer is going to try and connect to it. So the algorithm above would be great if I could save and use the connection from NWListener to send messages over.

NetworkFramework and UDP Broadcast Mode (2025)
So it seems the NetworkFramework is still not able to support Broastcast Mode am I correct?

iOS 18.4 key usage requirements fails TLS connections
iOS 18.4 introduced some requirements on the Key Usage of 802.1x server certificates, as described here. https://support.apple.com/en-us/121158 When using TLS_ECDHE_RSA or TLS_DHE_RSA cipher suites, 802.1X server certificates containing a Key Usage extension must have Digital Signature key usage set. When using the TLS_RSA cipher suite, 802.1X server certificates containing a Key Usage extension must have Key Encipherment key usage set. It reads like the change is supposed to affect 802.1x only. However, we have found out that the new restrictions are actually imposed on all TLS connections using the Network framework, including in Safari. Unlike other certificate errors which can be either ignored by users (as in Safari) or by code (via sec_protocol_options_set_verify_block), these new ones can't. Even if passing completion(true) in the TLS verification block, the connection still ends up in waiting state with error -9830: illegal parameter. I understand that these requirements are valid ones but as a generic TLS library I also expect that Network framework could at least allow overriding the behavior. The current treatment is not consistent with those on other certificate errors. Since I can't upload certificates, here is how to reproduce a certificate that fails. Create a OpenSSL config file test.cnf [ req ] default_bits = 2048 distinguished_name = dn x509_extensions = v3_ca prompt = no [ dn ] CN = example.com [ v3_ca ] subjectKeyIdentifier = hash authorityKeyIdentifier = keyid:always,issuer basicConstraints = CA:TRUE keyUsage = critical, keyCertSign, cRLSign Generate certificate and private key openssl req -x509 -new -nodes -keyout key.pem -out cert.pem -days 365 -config test.cnf And here is the client code to test. // Target server and port let host = NWEndpoint.Host("example.com") let port = NWEndpoint.Port("443")! // Configure insecure TLS options let tlsOptions = NWProtocolTLS.Options() sec_protocol_options_set_verify_block(tlsOptions.securityProtocolOptions, { _, _, completion in // Always trust completion(true) }, DispatchQueue.global()) let params = NWParameters(tls: tlsOptions) let connection = NWConnection(host: .init(host), port: .init(rawValue: port)!, using: params) connection.stateUpdateHandler = { newState in switch newState { case .ready: print("TLS connection established") case .failed(let error): print("Connection failed: \(error)") case .cancelled: print("Connection canceled") case .preparing: print("Connection preparing") case .waiting(let error): print("Connection waiting: \(error)") case .setup: print("Connection setup") default: break } } connection.start(queue: .global()) Output Connection preparing Connection waiting: -9830: illegal parameter Previously reported as FB17099740

Drop from URLSession to Network framework for SNI
Hi Dev Forums and Quinn "The Eskimo!", Short version Is there sample NWConnection code available that behaves in a similar way to the higher level URLSession and URLRequest APIs? Long version I have not been able to make this question get past the "sensitive language filter" on the dev forums. I figured it might be 'fool' or 'heck', or the X link, but removing each of those still triggers the sensitive language filter. Please see this gist: https://gist.github.com/lzell/8672c26ecb6ee1bb26d3aa3c7d67dd62 Thank you! Lou Zell

How to Access WiFi Connection Channel in iOS App?
Hi everyone, I'm developing an enterprise iOS application and need to access the WiFi connection channel. I understand that Apple's privacy and security policies restrict direct access to certain network details, including the WiFi connection channel. After some research, I found that this data might be accessible via the private API MobileWiFi.framework. However, when I tried to use this framework, I encountered the following error: Missing com.apple.wifi.manager-access entitlement I reached out to Apple regarding this entitlement, but they were not familiar with it, suggesting it might be deprecated. Here are my questions: Is there an official or supported way to access the WiFi connection channel in an enterprise iOS app? If not, is there any workaround or additional steps required to use the MobileWiFi.framework without encountering the entitlement error? Are there any specific entitlements or provisioning profile configurations that I need to be aware of to resolve this issue? Any guidance or suggestions would be greatly appreciated. Thank you!

macOS does not see an _smb._tcp service defined via Wide-Area DNS-SD
My laptop (M1 Pro, macOS 15.3.2) is connected to a dual stack network via Wi-Fi. The home.arpa. domain is supplied as a search domain via both DHCPv4 (options 15 and 119) and DHCPv6 (option 24). "Details…" for the network connection in System Settings show this domain under the DNS tab. The laptop uses a Forwarding DNS Resolver of my router, which in turn forwards requests for home.arpa. (including subdomains) to a local DNS server (CoreDNS) which is authoritative for this zone. The DNS server is configured via the following zone file: $ORIGIN home.arpa. $TTL 3600 @ IN SOA @ nobody.invalid.

Real time collaboration app
Good day, this is a concept maybe newbie question… what would be the best approach to develop the real time app… what I want is to be able to connect one device to other one within the app, and for example, if the app has a draggable object, then if one user drags the object, the other user see the object moving in real time I his own device, maybe using a ghost mode when interacting… this way both users using the app can interact with the objects in real-time. It’s not a game, so there’s no score… could I use gamecenter? or multipeer connectivity over BT? Is there a native framework? wich would be the easiest and less battery and system consuming approach someone could suggest? thank you in advance….

Connecting to a service found by Bonjour isn't working.
I'm using NWBrowser to search for a server that I hosted. The browser does find my service but when it tries to connect to it, it gets stuck in the preparing phase in NWConnection.stateUpdateHandler. When I hardcode the local IP address of my computer (where the server is hosted) into NWConnection it works perfectly fine and is able to connect. When it gets stuck in the preparing phase, it gives me the warnings and error messages in the image below. You can also see that the service name is correct and it is found. I have tried _http._tcp and _ssh._tcp types and neither work. This is what my code looks like: func findServerAndConnect(port: UInt16) { print("Searching for server...") let browser = NWBrowser(for: .bonjour(type: "_ssh._tcp", domain: "local."), using: .tcp) browser.browseResultsChangedHandler = { results, _ in print("Found results: \(results)") for result in results { if case let NWEndpoint.service(name, type_, domain, interface) = result.endpoint { if name == "PocketPadServer" { print("Found service: \(name) of type \(type_) in domain \(domain) on interface \(interface)") // Construct the full service name, including type and domain let fullServiceName = "\(name).\(type_).\(domain)" print("Full service name: \(fullServiceName), \(result.endpoint)") self.connect(to: result.endpoint, port: port) browser.cancel() break } } } } browser.start(queue: .main) } func connect(to endpoint: NWEndpoint, port: UInt16) { print("Connecting to \(endpoint) on port \(port)...") // endpoint = NWEndpoint( let tcpParams = NWProtocolTCP.Options() tcpParams.enableFastOpen = true tcpParams.keepaliveIdle = 2 let params = NWParameters(tls: nil, tcp: tcpParams) params.includePeerToPeer = true // connection = NWConnection(host: NWEndpoint.Host("xx.xxx.xxx.xxx"), port: NWEndpoint.Port(3000), using: params) connection = NWConnection(to: endpoint, using: params) connection?.pathUpdateHandler = { path in print("Connection path update: \(path)") if path.status == .satisfied { print("Connection path is satisfied") } else { print("Connection path is not satisfied: \(path.status)") } } connection?.stateUpdateHandler = { newState in DispatchQueue.main.async { switch newState { case .ready: print("Connected to server") self.pairing = true self.receiveMessage() case .failed(let error): print("Connection failed: \(error)") self.isConnected = false case .waiting(let error): print("Waiting for connection... \(error)") self.isConnected = false case .cancelled: print("Connection cancelled") self.isConnected = false case .preparing: print("Preparing connection...") self.isConnected = false default: print("Connection state changed: \(newState)") break } } } connection?.start(queue: .main) }

iOS 18.5 update live streaming bug
Our app supports live streaming (RTSP, RTMP, WebRTC) functionality. After updating to the 18.5 Developer Beta version, we’ve encountered an issue where streaming over LTE is not working for customers using SKT (SK Telecom) as their carrier. Upon investigation, it seems that a similar issue might be occurring with a streaming service app called "SOOP." I would appreciate it if you could share any information regarding this bug. Thank you.

virtio_net_hdr recommendations
Hey there! I’ve got some exciting news about Apple’s virtio_net_hdr implementation on macOS 15.4. It’s making communication a lot smoother, with a noticeable improvement! Now, I’d love to hear your thoughts on a couple of things. First, how do you think we can validate the populated values? And secondly, should we consider reusing populated values for the other endpoint, like the ‘flags’ field? Your insights would be invaluable!

iPhone failure to get IP from DHCP on WiFi model RN171
I have written an App which extracts data, over WiFi, from an instrument that creates its own WiFi Hotspot. The instrument provides no internet connection. The iPad version of this App is connects fine and is assigned an IP address by DHCP server running on a MicroChip RN171 wifi module. iOS assigns an obscure IP address on a completely different subnet. I understand this is iOS' way of "Complaining" that is wasn't assigned an IP address. Consequently in the case of the iPhone I am forced to manually assign an IP address for the iPhone, the mask and the gateway. Only then is the connection successful. Anyone know why the iPhone won't talk DHCP to a WiFi module not connected to the internet? Are there perhaps some parameters that I need to adjust on either the iPhone or WiFi module?

Can't connect to websocket from macOS game template
Hi, I'm trying to setup a simple websocket connection from the project game template. Using NWWebSocket 0.5.4 or urlSession.webSocketTask on the client and Vapor on the server. Haven't been able to connect since macOS ~14-15 with the same Xcode settings. I can send HTTP routes but the websocket itself does not connect. The closest I've got is connect but then immediate disconnect. I know the websocket works with CLI. Have plist allowing arbitrary loads and local networking. Also App Sandbox with network boxes checked in Debug mode. The error I get is: Error receiving: Error Domain=NSURLErrorDomain Code=-1011 "There was a bad response from the server." UserInfo={NSErrorFailingURLStringKey=http://localhost:8090/echo, NSErrorFailingURLKey=http://localhost:8090/echo, _NSURLErrorWebSocketHandshakeFailureReasonKey=5, NSLocalizedDescription=There was a bad response from the server.} Failed to send message: Error Domain=NSURLErrorDomain Code=-1011 "There was a bad response from the server." Thanks.

packet-tunnel-provider-systemextension doesn't work
I am currently creating a MacOS app that uses NetworkExtension and SystemExtension without going through the Store. Using entitlements, I manually codesign and create a pkg Installer, but when I run it I get an error message saying "No matching profile found." Below is the log /Applications/Runetale.app/Contents/MacOS/Runetale not valid: Error Domain=AppleMobileFileIntegrityError Code=-413 "No matching profile found" UserInfo={NSURL=file:///Applications/Runetale.app/, unsatisfiedEntitlements=&lt;CFArray 0x71c040fa0 [0x1f7bec120]&gt;{type = immutable, count = 3, values ​​= ( 0 : &lt;CFString 0x71c04f340 [0x1f7bec120]&gt;{contents = "com.apple.developer.system-extension.install"} 1 : &lt;CFString 0x71c1ccaf0 [0x1f7bec120]&gt;{contents = "com.apple.developer.networking.networkextension"} 2 : &lt;CFString 0x71c04fc00 [0x1f7bec120]&gt;{contents = "com.apple.developer.team-identifier"} )}, NSLocalizedDescription=No matching profile found} I looked into it myself and found that if you want to install the app without going through the Store, you need to use packet-tunnel-provider-systemextension instead of packet-tunnel-provider. here However, simply changing to packet-tunnel-provider-systemextension does not allow the build to pass. I use a build method that changes the value of entitlements only during codesign in order to pass the build. SYSEXT="$APP_BUNDLE/Contents/Library/SystemExtensions/com.runetale.desktop.PacketTunnel.systemextension" if [ -d "$SYSEXT" ]; then echo "Signing PacketTunnel system extension with entitlements..." cp macos/PacketTunnel/PacketTunnelRelease.entitlements macos/PacketTunnel/PacketTunnelRelease-sign.entitlements sed -i '' 's/packet-tunnel-provider/packet-tunnel-provider-systemextension/' macos/PacketTunnel/PacketTunnelRelease-sign.entitlements codesign --force --options runtime --timestamp --entitlements "$ENTITLEMENTS_FILE" --sign "$DEV_ID_APP_CERT" "$SYSEXT" fi # 3. Sign the entire .app bundle (deep sign by signing the outer app after inner ones) echo "Signing Runetale App with entitlements..." cp macos/Runner/Release.entitlements macos/PacketTunnel/Release-sign.entitlements sed -i '' 's/packet-tunnel-provider/packet-tunnel-provider-systemextension/' macos/PacketTunnel/Release-sign.entitlementsmacos/PacketTunnel/Release-sign.entitlements codesign --force --options runtime --timestamp --entitlements "$APP_ENTITLEMENTS_FILE" --sign "$DEV_ID_APP_CERT" "$APP_BUNDLE" Is this build method wrong? The next solution I'm thinking of is as follows. Is there a way to write packet-tunnel-provider-systemextension directly to entitlments and pass the build? (provisioning profile?) Apply to forum and get permission to use packet-tunnel-provider-systemextension Thank you.

wifi connect fail
Dear Apple: In our app, we will call the - (void) applyConfiguration:(NEHotspotConfiguration *) configuration completionHandler:(void (^)(NSError * error)) completionHandler; interface of NEHotspotConfigurationManager on Apple devices. However, we are encountering a problem where the connection to the 2.4G hotspot fails, and the error is nil when it fails. We checked the Wi-Fi air interface and found that the Apple phone does not send a probe request before connecting to the hotspot. However, we are unclear why the Apple device does not send the probe request frame. Could you please help us understand when the probe request frame is not sent during the hotspot connection and how to trigger it to send the probe request frame every time? Thank you.

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!
