iOS 26 NWPathMonitor dont handle any updates - always all good.

plateform: iPadOS 16.3.1 xcode:15.2 code: self.queue = Queue() self.monitor = NWPathMonitor() self.monitor.pathUpdateHandler = { [weak self] path in queue.async { } }

Apple's Wi-Fi Aware demo shows that pairing is required before establishing a connection. Is this pairing mandatory? Can Android devices pair with Apple devices? My Android device strictly supports Wi-Fi Aware 4.0 and I want to achieve interoperability with Apple devices.

I'm writing a SwiftUI LDAP Browser. I built a command line swift app to do some testing and it works fine. I had to add the certificates from the LDAP server to the system keychain before it would work with TLS/SSL. Then I ported the same code into a SwiftUI app but I cannot get it to connect via TLS/SSL. On the same machine with the same certs it errors with: An unexpected error occurred: message("Can't contact LDAP server") It connect fine with our TLS/SSL. I suspect this may have to do with App Transport Security. Can anyone point me in the right direction to resolve this? App is MacOS only.

Simulator: iPhone 16 pro (iOS 26) Minimum Deployments: iOS 16.0+, not iOS 17. Here is the demo: import SwiftUI import NetworkExtension struct ContentView: View { private var monitor = NWPathMonitor() var body: some View { VStack { Text("Hello, world!") } .task { let _ = URLSession.shared } } }

Hello, I have encountered an issue with an iPhone 15PM with iOS 18.5. The NSHTTPCookieStorage failed to clear cookies, after clearing them, I was still able to retrieve them. However, on the same system NSHTTPCookie *cookie; NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage]; for (cookie in [storage cookies]) { [storage deleteCookie:cookie]; } NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:[[self url] absoluteURL]]; // still able to get cookies,why???

We're experiencing an issue with Local Network Permission. When trying to connect to a socket, the Local Network Permission alert pops up. To trigger the permission request at the start of the app, we used the following code to ask for permission and receive a callback on whether it's granted. However, this approach doesn't always trigger the permission alert, or it gets automatically dismissed after 30 seconds, only to reappear later. What could be causing this inconsistent behavior? func checkLocalNetworkPermission(_ completed: Optional<(Bool) -> Void> = .none) { DispatchQueue.global(qos: .userInitiated).async { let hostName = ProcessInfo.processInfo.hostName let isGranted = hostName.contains(".local") if let completed { DispatchQueue.main.async { completed(isGranted) } } } }

We are developers of an app, we found that there's no LN prompt for users to install the app for the 1st time on ios18. We used the following method to prompt the "allow/not allow" alert: // Attempts to trigger the local network privacy alert. /// /// This builds a list of link-local IPv6 addresses and then creates a connected /// UDP socket to each in turn. Connecting a UDP socket triggers the local /// network alert without actually sending any traffic. /// /// This is a ‘best effort’ approach, and it handles errors by ignoring them. /// There’s no guarantee that it’ll actually trigger the alert (FB8711182). func triggerLocalNetworkPrivacyAlert() { let addresses = selectedLinkLocalIPv6Addresses() for address in addresses { let sock6 = socket(AF_INET6, SOCK_DGRAM, 0) guard sock6 >= 0 else { return } defer { close(sock6) } withUnsafePointer(to: address) { sa6 in sa6.withMemoryRebound(to: sockaddr.self, capacity: 1) { sa in _ = connect(sock6, sa, socklen_t(sa.pointee.sa_len)) >= 0 } } } }

I have a question regarding /etc/pf.conf. If I use this rule, rdr pass on bridge100 inet proto tcp from 192.168.2.104 to any port {80, 443, 8883} -> 127.0.0.1 port 8080 all other traffic on bridge100 will not function properly, even the traffic that is not destined for 192.168.2.104. Additionally, the hotspot generated through bridge100 will also become unavailable. Even if I comment out this rule and run sudo pfctl -e -f /etc/pf.conf, the problem still persists. The situation will only return to normal when I restart my Mac. my macos:15.3.2 my /etc/pf.conf # scrub-anchor "com.apple/*" nat-anchor "com.apple/*" rdr-anchor "com.apple/*" rdr pass on bridge100 inet proto tcp from 192.168.2.104 to any port {80, 443, 8883} -> 127.0.0.1 port 8080 dummynet-anchor "com.apple/*" anchor "com.apple/*" load anchor "com.apple" from "/etc/pf.anchors/com.apple"

We have an application which is written in Swift, which activates network extension (Transparent Proxy). We want to use MDM deployment for this network system extension. Our Transparent Proxy module is a system extension, which is exposing an app proxy provider interface (We are using NETransparentProxyProvider class and in extension’s Info.plist we use com.apple.networkextension.app-proxy key.) We don’t have any remote server setup to forward the traffic, instead we open a connection with a certain localhost:port to redirect the traffic which is received in our transparent proxy. We have another module that listens to the particular localhost:port to process the traffic further. As per https://developer.apple.com/documentation/devicemanagement/vpn/transparentproxy documentation, we noticed that we can use the VPN payload with app-proxy as Provider Type for Transparent Proxy. We were able to install the profile created via Jamf Pro and also while in stalling our product the Transparent Proxy gets mapped with the one which is installed via profile. However after that the network is broken and hence unable to browse anything. We are suspecting the remote server filed is causing this. So we tried creating the custom profile without remote server address for VPN payload, but we are unable to install the profile. It throws below error: 2025-02-11 16:43:55.193348+0530 0x2f880 Error 0x0 6815 0 mdmclient: (NetworkExtension) [com.apple.networkextension:] Failed to save configuration DGWebProxy because it is invalid: Error Domain=NEConfigurationErrorDomain Code=2 "configuration is invalid: Missing server address" UserInfo={NSLocalizedDescription=configuration is invalid: Missing server address}

I'm using Network framework for communication between devices. The first time I instantiate an NWBrowser, it will prompt the user with a popup that says: Allow &lt;app name&gt; to find devices on local networks? The problem is, once I upgraded from Xcode 15.4 to Xcode 16.4, the popup doesn't appear; it says in the debug window: nw_browser_fail_on_dns_error_locked [B1] nw_browser_dns_service_browse_callback failed: PolicyDenied(18,446,744,073,709,486,046) I do have the info.plist keys Privacy-Local Network Usage Description (NSLocalNetworkUsageDescription) and Bonjour Services (NSBonjourServices) so it's not that. Also, It still works on a real device. I think something changed with Xcode 16 that tightened the security on a simulator, or maybe disabled Network framework entirely. It's not the firewall on my computer because that is turned off. I'm using an M1 MacBook Pro.

Hi guys, I try to create a content filter app by using network extension api. When it comes to a https/tls remote endpoint, the remoteEndpoint.hostname will always be "" instead of the actual hostname. How can I extract the actual hostname? private func filterTraffic(flow: NEFilterSocketFlow) -> NEFilterNewFlowVerdict { // Default action from settings will be used if no rules match logger.error("filter traffic...") guard let remoteEndpoint = flow.remoteEndpoint as? NWHostEndpoint else { logger.error("not a NWHostEndpoint)") return .allow() } logger.error("host name: \(remoteEndpoint.hostname)") if remoteEndpoint.hostname.hasSuffix("google.com"){ logger.error("google.com") return .drop() } return .allow() } code-block

NEFilterManager.shared().loadFromPreferences { loadError in DispatchQueue.global.async { ... } } the code above is executed in an app-like deamon and completionHandler was never invoked, same code in an application works fine.(they are both packed with content filter network system extension) is it because of the restriction of app-like deamon?

I am making a USB attached IoT device that follows the Matter approach to connectivity (IP/mDNS/DHCP). I am having conflicts with it as it appears to MacOS as an Ethernet adapter and this is causing it to be assigned as a "default" route, interfering with routing when my Mac is connected to NAT based WiFi. I'd like to be able to hint to MacOS & iPadOS that this is not a routable private network, the subnet should be respected and a default route should not be assigned to it, otherwise the order of the device connection is used by the IP routing tables and I am concerned my non-routable private network will initialize before Wifi and block NAT based internet connectivity. How can I hint to MacOS/iPadOS "this is not a routable private network, this is not a NAT, do not assign me a default route beyond the subnet I have provided you."

Hi~ I implemented network filtering on iOS using NEFilterControlProvider and NEFilterDataProvider. However, I found that their usage is restricted when distributing through the App Store. Does ADEP-based distribution allow the use of NEFilterControlProvider and NEFilterDataProvider? In TN3134, it states that NEPacketTunnelProvider requires MDM. Should I assume that NEFilterControlProvider and NEFilterDataProvider also require MDM in the same way? Thanks

Hello, I’m developing an iOS app with Xcode (Objective-C / Swift), and I would like to know if there is any supported way to retrieve a list of nearby Wi-Fi networks (their SSID and signal strength). I know that NEHotspotConfigurationManager allows to configure a specific network, and the Access WiFi Information entitlement allows getting the current connected network. But is there any API (public, private, or special entitlement) that allows scanning nearby Wi-Fi networks — even for limited purposes like configuration of IoT equipment, or MFi devices? I have seen some apps doing this in the past (probably via private API), but I want to know what is the current official solution. Thanks a lot!

I am creating an application that needs to connect to an Iot device, so i want to make a wifi hotspot with a custom SSID and password and WPA3. Could you please provide an example code in Objective-C to get started?

We have a setup where the system uses proxy settings configured via a PAC file. We are investigating how NWConnection behaves inside a Network Extension (NETransparentProxyProvider) with a transparent proxy configuration based on this PAC file. Scenario: The browser makes a connection which the PAC file resolves as "DIRECT" (bypassing the proxy) Our Network Extension intercepts this traffic for analysis The extension creates a new connection using NWConnection to the original remote address. The issue: despite the PAC file’s "DIRECT" decision, NWConnection still respects the system proxy settings and routes the connection through the proxy. Our questions: Is it correct that NWConnection always uses the system proxy if configured ? Does setting preferNoProxies = true guarantee bypassing the system proxy? Additionally: Whitelisting IPs in the Network Extension to avoid interception is not a viable solution because IPs may correspond to multiple services, and the extension only sees IP addresses, not domains (e.g., we want to skip scanning meet.google.com traffic but still scan other Google services on the same IP range). Are there any recommended approaches or best practices to ensure that connections initiated from a Network Extension can truly bypass the proxy (for example, for specific IP ranges or domains)?

i unfortunatly upgraded to Sequoia since then I see when: i select XCode -&gt;Product-&gt;run i see Error: No route to host i cannot grant access to local network for XCode i can no longer debug my program as i did with Sonora

I’m developing an app designed for hospital environments, where public internet access may not be available. The app includes two components: the main app and a Local Connectivity Extension. Both rely on persistent TCP socket connections to communicate with a local server. We’re observing a recurring issue where the extension’s socket becomes unresponsive every 1–3 hours, but only when the device is on the lock screen, even if the main app remains in the foreground. When the screen is not locked, the connection is stable and no disconnections occur. ❗ Issue Details: • What’s going on: The extension sends a keep-alive ping packet every second, and the server replies with a pong and a system time packet. • The bug: The server stops receiving keep alive packets from the extension.  • On the server, we detect about 30 second gap on the server, a gap that shows no packets were received by the extension. This was confirmed via server logs and Wireshark).  • On the extension, from our logs there was no gap in sending packets. From it’s perspective, all packets were sent with no error.  • Because no packet are being received by the server, no packets will be sent to the extension. Eventually the server closes the connection due to keep-alive timeout.  • FYI we log when the NEAppPushProvider subclass sleeps and it did NOT go to sleep while we were debugging. 🧾 Example Logs: Extension log: 2025-03-24 18:34:48.808 sendKeepAliveRequest() 2025-03-24 18:34:49.717 sendKeepAliveRequest() 2025-03-24 18:34:50.692 sendKeepAliveRequest() ... // continuous sending of the ping packet to the server, no problems here 2025-03-24 18:35:55.063 sendKeepAliveRequest() 2025-03-24 18:35:55.063 keepAliveTimer IS TIME OUT... in CoreService. // this is triggered because we did not receive any packets from the server 2025-03-24 18:34:16.298 No keep-alive received for 16 seconds... connection ID=95b3... // this shows that there has been no packets being received by the extension ... 2025-03-24 18:34:30.298 Connection timed out on keep-alive. connection ID=95b3... // eventually closes due to no packets being received 2025-03-24 18:34:30.298 Remote Subsystem Disconnected {name=iPhone|Replica-Ext|...} ✅ Observations: • The extension process continues running and logging keep-alive attempts. • However, network traffic stops reaching the server, and no inbound packets are received by the extension. • It looks like the socket becomes silently suspended or frozen, without being properly closed or throwing an error. ❓Questions: • Do you know why this might happen within a Local Connectivity Extension, especially under foreground conditions and locked ? • Is there any known system behavior that might cause the socket to be suspended or blocked in this way after running for a few hours? Any insights or recommendations would be greatly appreciated. Thank you!
