I am working on a VPN app featuring Wireguard. The app was working fine. I planned to make a Framework for the Wireguard Target, Network Extension Target and the Code managing VPN, Now after removing all errors, resolving Bundle IDs and making all the targets compatible to iOS 16.0, I am getting this error in the Settings app as shown in the following In short, same code is not working when moved into the framework. I have read the similar thread talking about lowering the minimum deployments. All of my minimum deployments are set to iOS 16.0. Any suggestions would be appreciated. Thanking you in anticipation.

On the [documentation page](Implement a completely custom DNS proxying protocol) it says For example, a DNS proxy provider might: Implement a completely custom DNS proxying protocol I would like to add some filtering logic to the NEDNSProxyProvider (for example, return nxdomain if the flow is not passing the filtering process). Is it possible to implement with NEDNSProxyProvider? It also says that func handleNewFlow(_ flow: NEAppProxyFlow) -> Bool from NEDNSProxyProvider returns a Boolean value set to true if the proxy implementation decides to handle the flow, or false if it instead decides to terminate the flow link. Does it mean that the filtering logic could be added here by just returning false for the flows that are not matching the rules? Because I first tried to handle UDP flows like this in handleNewFlow(_ flow: NEAppProxyUDPFlow) function and form my own packets in connection.transferData, by first passing empty Data object and then by setting RCODE to 3, which is supposedly a nxdomain response code. However, both implementations didn't work: even though I was getting logs about handling failure, the flow was still able to go through. try await flow.open(withLocalEndpoint: flow.localEndpoint as? NWHostEndpoint) let datagrams = try await flow.readDatagrams() let results = try await datagrams.parallelMap { let connection = try DatagramConnection($0) return try await connection.transferData() } try await flow.writeDatagrams(results) flow.closeReadWithError(nil) flow.closeWriteWithError(nil) I am new to NEDNSProxyProvider and my networking knowledge is on a pretty basic level, so I would be very grateful to hear any suggestions. Thank you!

I want to use Network Extension Relay to implement a system-wide proxy. First, I will setup a local http2 proxy and forward to a local http proxy. The problem is How to implement this http2relayurl link to? Is it a regular http2 proxy protocol? What should I pass to raw public keys? Is it a bytes like rsa public key, or is .pem, .pub like plain text string? And I will use self signed certificate, will it be a problem?

hi, I made an interface for VPN applications for iOS, and I just need to make a connection to the protocol, I wanted to use wireguard, but I can’t do it, what can you suggest me?

How can you change the behaviour of the system resolver on iOS? need help eskimo..!

Hello, we are developing an open source vpn program that is developed with Flutter and native parts with Swift, and we plan to publish it on the App Store soon, but the project programmers say that you must have an account to publish this app on the App Store. On the other hand, my other friends say that this is not the case, and to publish a vpn app, only one Apple Developer account is enough, and there is no need for a business account!

Hey everyone, I'm currently working on an app where I've already implemented a packet tunnel provider. Now, I'm looking to introduce a content filter. One crucial feature I need is the ability to read the bundle ID of the app originating the network flows. However, I've hit a roadblock when combining both components; When I run the content filter sans packet tunnel provider, I can read the originating app's bundle ID for network flows just fine. But when I add packet tunnel provider, the app's bundle ID defaults to my own app's bundle ID, which is unexpected. Has anyone else encountered this? Any thoughts on why it's happening or how to fix it? Cheers!

Hi, I was working on some new filtering logic for my Content Filter that I would like to add. It involves making requests to remote DNS resolvers. Is it possible to use it within sync override func handleNewFlow(_ flow: NEFilterFlow) -> NEFilterNewFlowVerdict of the NEFilterDataProvider? As of right now, I have a concept working in Command Line Tool and playground, however, when I try to add working module to the main project, it's not working (connections are not loading). Function that makes requests to the servers: In this function I use DispatchGroup and notify for non-main queue @available(iOS 12, *) public class NetworkService { private let nonMainQueue: DispatchQueue = DispatchQueue(label: "non-main-queue") func isBlocked(hostname: String, completion: @escaping (Bool) -> Void) { var isAnyBlocked = false let group = DispatchGroup() for server in servers { group.enter() let endpoint = NWEndpoint.Host(server) query(host: endpoint, domain: hostname, queue: .global()) { response, error in defer { group.leave() } /* * some code that determines the filtering logic * if condition is true => isAnyBlocked = true & return */ } } group.notify(queue: nonMainQueue) { completion(isAnyBlocked) } } } And, for example, in playground Semaphores make it work as expected, but the same approach doesn't work with the NEFilterDataProvider playground code sample let hostname = "google.com" func returnResponse() -> String { var result = "" let semaphore = DispatchSemaphore(value: 0) DispatchQueue.global().async { NetworkService.isBlocked(hostname: hostname) { isBlocked in result = isBlocked ? "blocked" : "allowed" semaphore.signal() } } semaphore.wait() return result } print(returnResponse()) Output: allowed

MacOS Version: 14.3 (23D56) In my testing of PacketTunnelProvider on MacOS I have observed that when I do a system shutdown or reboot, PacketTunnelProvider::stopTunnelWithReason() is getting called with reason: NEProviderStopReasonUserInitiated. Note: when I try to disconnect the VPN from system settings PacketTunnelProvider::stopTunnelWithReason() is called with the same reason: NEProviderStopReasonUserInitiated. I am facing an issue here to identify what caused PacketTunnelProvider::stopTunnelWithReason(), system shutdown or any user action?

We want to display our application name should be suggested on wifi network which are insecure. Similar like following: Please suggest, which class or extension we can use for achieve this.

hello everyone, I want to create VPN app with swiftUI but i do not know where to start. I have already created some beautiful UI but now i want to configurate network to connect another country server. any suggestions?

Description: I am experiencing a persistent issue with establishing a VPN connection through a custom app I've developed using Swift. While the VPN configuration appears to be loaded successfully, attempts to connect result in immediate disconnection. Here are the details: Problem Summary: I have implemented a VPN connection using Swift with the NetworkExtension and TunnelKit frameworks. My application successfully loads the VPN configuration, but when attempting to connect, the VPN status quickly changes from connecting to disconnected without ever achieving a stable connection. Manually attempting to toggle the connection from device settings results in the toggle switching off as soon as it is turned on. The console logs indicate a transition from 'connecting' to 'disconnected' almost simultaneously. Technical Details: Here is an overview of the relevant part of the code used for setting up and managing the VPN connection: import TunnelKitOpenVPNCore import NetworkExtension import TunnelKit class VPNManager { static let shared = VPNManager() private var providerManager: NETunnelProviderManager? init() { NotificationCenter.default.addObserver(self, selector: #selector(vpnStatusDidChange), name: .NEVPNStatusDidChange, object: nil) } deinit { NotificationCenter.default.removeObserver(self) } @objc func vpnStatusDidChange(notification: Notification) { guard let status = self.providerManager?.connection.status else { return } switch status { case .connecting: print("VPN is connecting") case .connected: print("VPN is connected") case .disconnecting: print("VPN is disconnecting") case .disconnected: print("VPN is disconnected") case .invalid: print("VPN configuration is invalid") case .reasserting: print("VPN is reasserting") @unknown default: print("Unknown VPN status") } } func loadAndCreateVPNProfile(completion: @escaping (Bool, Error?) -> Void) { self.providerManager = NETunnelProviderManager() guard let ovpnURL = Bundle.main.url(forResource: "client", withExtension: "ovpn"), let ovpnContents = try? String(contentsOf: ovpnURL) else { completion(false, NSError(domain: "VPNManagerError", code: 1, userInfo: [NSLocalizedDescriptionKey: "Configuration file could not be read or found."])) return } // Parsing and configuration logic here... self.providerManager?.saveToPreferences { error in if let error = error { print("Error saving preferences: \(error.localizedDescription)") completion(false, error) } else { print("VPN profile saved successfully.") completion(true, nil) } } } func connect() { self.providerManager?.loadFromPreferences { [weak self] error in guard let strongSelf = self else { print("Reference to VPNManager lost.") return } if let error = error { print("Failed to load preferences: \(error.localizedDescription)") return } do { try strongSelf.providerManager?.connection.startVPNTunnel() } catch NEVPNError.configurationInvalid { print("VPN Configuration is invalid.") } catch NEVPNError.configurationDisabled { print("VPN Configuration is disabled.") } catch let error { print("Unexpected error: \(error.localizedDescription)") } } } func disconnect() { providerManager?.connection.stopVPNTunnel() } }

I work on an app that includes a network extension. The app is essentially just to activate the extension, and the extension typically has long-running background sessions. Analyzing/monitoring metrics for the network extension is very important for us. However, in the Xcode Organizer screen, only the app itself is shown in the drop down menu - the associated network extension is not an option. For Xcode Organizer screens like Termination metrics and Battery Usage metrics, does the app's background metrics include the network extension, or just the app itself? If just the app, is there any way to get these metrics for the network extension?

I've implemented a NEPacketTunnelProvider implementation, but I can't see any packets in packet flow. Here is the settings override func startTunnel(options: [String : NSObject]?, completionHandler: @escaping (Error?) -> Void) { ... let networkSettings = self.initTunnelSettings() setTunnelNetworkSettings(networkSettings) { (error) in if let error = error { completionHandler(error) return } NSLog("Proxy address: \(networkSettings.proxySettings?.httpsServer?.address)") self.readPackets() completionHandler(nil) } private func initTunnelSettings() -> NEPacketTunnelNetworkSettings { let settings: NEPacketTunnelNetworkSettings = NEPacketTunnelNetworkSettings(tunnelRemoteAddress: "85.182.68.10") /* ipv4 settings */ settings.ipv4Settings = NEIPv4Settings(addresses: ["1.2.3.4"], subnetMasks: ["255.255.255.255"]) settings.ipv4Settings?.includedRoutes = [NEIPv4Route.default()] /* MTU */ settings.mtu = 1500 return settings } There is even more strange thing. If I add more specific route into includedRoutes array, I can see packets from that route traffic settings.ipv4Settings?.includedRoutes = [NEIPv4Route.default(), NEIPv4Route(destinationAddress: "192.168.0.103", subnetMask: "255.255.255.252")] With this changes I will see packets with the destination IP "192.168.0.103", but if change mask to 255.255.255.0 no packet in the packet flow again settings.ipv4Settings?.includedRoutes = [NEIPv4Route.default(), NEIPv4Route(destinationAddress: "192.168.0.103", subnetMask: "255.255.255.0")] Anyway my goal is to route all traffic through virtual interface and get all packets in the packetFlow. Can you help me? What should I change?

HI Team, We have recently observed a network issue, followed by device hang-ups when users come out of sleep while using the Transparent app proxy provider in Sonoma 14.4. and users are required to restart the system to resolve the problem. In the client logs, we observed that State:/Network/Global/IPv4 does not have any PrimaryInterface and there is no internet connectivity, although the internet works fine on other devices. this issue start coming in sonoma 14.4 and happen with Transparent app proxy provider. We are currently unable to pinpoint the exact issue. Are there any known issues with Sonoma 14.4?

Even when it is disabled (that is, our app says "don't do anything" and all it does is start logging things). On the mac, when I try to make an outgoing audio-only call (it's a mac mini with no camera), it seems to connect as far as the outside is concerned, but nothing happens -- I get a request on my other devices, with the wrong account, and the mac mini says it's failed while the ipad or iphone keep connected. I am logging everything I can think of in our extensions, and they don't seem to show anything of interest. And I can't figure out what to look for in the entirety of system logs. I do see Messages dropped during live streaming (use log show to see what they were)... but I'm not sure what to look for in the log show. If I try to make a call in, it results in what seems to be an iOS FaceTime bug -- the phone tells me to log into FaceTime. Even though I am logged in.

I am running into an issue with running a PacketTunnelProvider as a system extension, and fast user switching. Since the VPN is running as root, it runs outside any user context, and is accessible to all users on the machine. I can see the following behavior: Login to User A Connect VPN Fast switch to user B Open Safari, observe that traffic is directed and sent out the VPN. (As noted by the ability to browse otherwise un-reachable websites). Is there a way to detect that a fast user switch is happening? And disconnect the VPN when user B takes control of the screen. I know NSWorkspace is not a daemon-safe API. So NSWorkspaceSessionDidResignActiveNotification and like will not be useful here. One alternative would be to use NSWorkspace notifications in the GUI and alert the system extension via XPC. But that wouldn't work in the case where there isn't a GUI, such as with ConnectOnDemand. Is there a daemon-safe API to use or some other alternative? Thanks

In iOS, how to use code to turn on the system's hotspot?

I would like to know, do we have any support from iOS in order to turn on wifi and bluetooth using internal apis on tap of a button in my IOS App, I am struggling to find information over this, more precisely , I want to turn on wifi from my custom widget in I phone, is it possible then please share info.
