I added a Content Filter to my app, and when running it in Xcode (Debug/Release), I get the expected permission prompt: "Would like to filter network content (Allow / Don't Allow)". However, when I install the app via TestFlight, this prompt doesn’t appear at all, and the feature doesn’t work. Is there a special configuration required for TestFlight? Has anyone encountered this issue before? Thanks!

I've implemented func urlSession(_ session: URLSession, task: URLSessionTask, willPerformHTTPRedirection response: HTTPURLResponse, newRequest request: URLRequest, completionHandler: @escaping (URLRequest?) -> Void) and func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didWriteData bytesWritten: Int64, totalBytesWritten: Int64, totalBytesExpectedToWrite: Int64) I've put a breakpoint in each but the BP in willPerformHTTPRedirection never fires. When the didWriteData fires and I inspect downloadTask.originalRequest I see my original request URL When I inspect downloadTask.currentRequest the returned request contains a different URL. I'm the farthest thing from an HTTP wizard, but I had thought when originalRequest differs from currentRequest there had been some sort of server-side 'redirection'. Is there a way for my code to receive a callback when something like this happens? NOTE: my download code works fine, I'm just hoping to detect the case when currentRequest changes. any/all guidance greatly appreciated on the off chance it helps, are are my original and current request values: (lldb) po downloadTask.originalRequest ▿ Optional<URLRequest> ▿ some : https://audio.listennotes.com/e/p/c524803c1a90412f922948274ecc3625/ (lldb) po downloadTask.currentRequest ▿ Optional<URLRequest> ▿ some : https://26973.mc.tritondigital.com:443/OMNY_HAPPIERWITHGRETCHENRUBIN_PODCAST_P/media-session/76cfceb2-1801-4570-b830-ded57611a9cf/d/clips/796469f9-ea34-46a2-8776-ad0f015d6beb/e1b22d0b-6974-4bb8-81ba-b2480119983c/2f35a8ca-b982-44e9-8122-b3dc000ae0e1/audio/direct/t1769587393/Ep_571_Want_to_Join_Us_for_a_No-Spend_February_Plus_a_Better_Word_for_Squats.mp3?t=1769587393&in_playlist=751ada7f-ded3-44b9-bfb8-b2480119985b&utm_source=Podcast

Case-ID: 17935956 In the NetworkExtension framework, for the NETransparentProxyProvider and NEDNSProxyProvider classes: when calling the open func writeDatagrams(_ datagrams: [Data], sentBy remoteEndpoints: [NWEndpoint]) async throwsin the NEDNSProxyProvider class, and the open func write(_ data: Data, withCompletionHandler completionHandler: @escaping @Sendable ((any Error)?) -> Void)in the NETransparentProxyProvider class, errors such as "The operation could not be completed because the flow is not connected" and "Error Domain=NEAppProxyFlowErrorDomain Code=1 "The operation could not be completed because the flow is not connected"" occur. Once this issue arises, if it occurs in the NEDNSProxyProvider, the entire system's DNS will fail to function properly; if it occurs in the NETransparentProxyProvider, the entire network will become unavailable.

I’m trying to determine the actual Wi-Fi band (e.g. 2.4GHz, 5GHz, or 6GHz) of the network that is currently connected on macOS. I’m not looking for a heuristic based on the Wi-Fi name (SSID), such as checking whether it contains “5G” or “6G”. Instead, I want a reliable and accurate method that reflects the real connection parameters reported by the system. Specifically, I’m interested in: Whether macOS exposes the current Wi-Fi band or channel information through public APIs (e.g. CoreWLAN) Or if there is any supported system-level way to retrieve this information programmatically If this information is not directly accessible, I’d also like to understand: Why macOS does not expose it And whether there is a recommended alternative approach Any insights or examples would be greatly appreciated.

Hi, i programmed an app the uses MultipeerConnectivity to connect iOS-Devices to exchange Video-Files from the camera (https://pellepepper.my.canva.site/jumpcontrol). In general the solution works fine but I have some challenges: The connection is pretty stable when there are only few other devices around. It seems to become more fragile when there are more other iOS-Devices in the area Testing of the App worked with several meters of distance (up to 10). In real environments of athletics venues the solution is only stable in a region of about 2 meters It seems that newer iOS-Releases make the connection more unstable. Last weekend we used it with iOS 18-Devices on older hardware, what worked fine. Integrating an iOS 26 device made trouble. Working on iPhone 13 with iOS 26 is hardly not usable. What can I do to improve stability of the connection and therefore the App. What are the metrics to look for? Is there something I can do on the code base to make to connection more stable? Many thx Rainer

I have noticed race conditions on macOS when tearing down and re-configuring an NEPacketTunnelProvider. My goal is to handle switching out one VPN profile for another identical/near identical one (I'll add some context for this below). The flow that I have tested was to wait for the NEVPNStatusDidChange notification to report a NEVPNStatus.disconnected state, and then start the process of re-configuring the VPN with a new profile. In practice however, I have noticed that I must wait a couple of seconds between NEVPNStatus.disconnected state being reported and setting up a new tunnel. Otherwise, the system routing table gets messed up but the VPN reports being in NEVPNStatus.connected state, resulting in a tunnel that appears healthy but can't be accessed. With this, I wanted to ask if you have any suggestions on any OS items I can observer, in order to deterministically know that the system has fully cleaned up my packet tunnel, and that I am safe to configure another? This would be much more optimal than a hard-coded delay. Additional context: Jamf is a common solution for deploying MDM configuration profiles. However, in my tests, it doesn't support Apple's recommended approach of using the PayloadIdentifier to mark profiles for replacement, as PayloadIdentifiers are automatically updated to match the PayloadUUID of that same profile on upload. Although given what I've observed, I'm not sure the Apple recommended approach would work here in any case. Additionally, it would be nice to transition from non-MDM to MDM cleanly, however, this also requires an indeterminate wait time between the non-MDM configuration being disconnected and subsequently removed, and the MDM one being configured. With these scenarios, we need to be able to add a second configuration, with possibly identical VPN settings, then remove the old one, allowing the system to transition to the new configuration. For the MDM case, the pattern I've noticed on the system is that when the current profile is suddenly deleted, the connection will go into disconnected state, then NEVPNConfigurationChange will fire. The new profile can be configured from NEVPNConfigurationChange, however some time is needed to avoid races. For non-MDM, I had experimented with an approach of polling for MDM configurations appearing. When they do, I'd remove my previous notification observers, and set up a new NEVPNStatusDidChange notification observer, to remove the non-MDM VPN configuration after. it enters a disconnected state. Following the removal, I would call a function to reconfigure the VPN with new configuration. When this logic is in place, the call to stopVPNTunnel() is made. Again, a hardcoded delay is required between stopping and removing the old configuration and setting up a new one. Thanks!

We’re developing an enterprise VPN client for macOS using NetworkExtension (PacketTunnelProvider) with Always-On / On-Demand VPN, deployed via MDM. On macOS 14.x and 15.x we observe the following log message from nesessionmanager: nesessionmanager: NESMVPNSession[...] Resetting VPN On Demand This most commonly occurs after sleep → wake. After this happens, the VPN no longer reconnects automatically, even though isOnDemandEnabled remains true and On-Demand rules are still present. Then a manual user action is required to reconnect. Questions: Is the “Resetting VPN On Demand” log message expected during sleep/wake transitions? Under what conditions does macOS reset On-Demand VPN state? Is there a supported way to detect or recover from this state programmatically? Any guidance on expected behavior or best practices would be appreciated.

I’m developing an iOS idle game (guild management). To detect manual device time changes that would break progression, I need a trusted “current real-world time” reference. I’m considering querying Apple’s NTP host time.apple.com, but I couldn’t find any official guidance about whether third-party apps may use time.apple.com directly (acceptable use, rate limits, whether it’s discouraged, etc.). Apple Developer Support couldn’t provide info and suggested asking on the forums. Questions: 1. Is it permitted for a third-party iOS app to query time.apple.com via NTP/SNTP (Yes/No or conditional)? 2. If permitted, are there any published or recommended constraints (rate limits, caching, prohibited patterns, commercial app considerations)? 3. If not permitted / not recommended, what is the recommended alternative approach (run our own time service, use public NTP pool, or any Apple-recommended mechanism)? 4. If there is any official document / policy covering this, could you point me to it? For context: I do not need sub-second accuracy and I do not intend high-frequency polling. If implemented at all, it would be very low frequency (e.g., first launch + once per 24h) with caching and graceful fallback on failure. My main goal is policy clarity rather than implementation details.

Hi, I’m implementing a macOS DNS Proxy as a system extension and running into a persistent activation error: OSSystemExtensionErrorDomain error 9 (validationFailed) with the message: extension category returned error This happens both on an MDM‑managed Mac and on a completely clean Mac (no MDM, fresh install). Setup macOS: 15.x (clean machine, no MDM) Xcode: 16.x Team ID: AAAAAAA111 (test) Host app bundle ID: com.example.agent.NetShieldProxy DNS Proxy system extension bundle ID: com.example.agent.NetShieldProxy.dnsProxy The DNS Proxy is implemented as a NetworkExtension system extension, not an app extension.

Activation code In the host app, I use: swift import SystemExtensions final class SystemExtensionActivator: NSObject, OSSystemExtensionRequestDelegate { private let extensionIdentifier = "com.example.agent.NetShieldProxy.dnsProxy" func activate(completion: @escaping (Bool) -> Void) { let request = OSSystemExtensionRequest.activationRequest( forExtensionWithIdentifier: extensionIdentifier, queue: .main ) request.delegate = self OSSystemExtensionManager.shared.submitRequest(request) } func request(_ request: OSSystemExtensionRequest, didFailWithError error: Error) { let nsError = error as NSError print("Activation failed:", nsError) } func request(_ request: OSSystemExtensionRequest, didFinishWithResult result: OSSystemExtensionRequest.Result) { print("Result:", result.rawValue) } } Runtime behavior on a clean Mac (no MDM) config.plist is created under /Library/Application Support/NetShield (via a root shell script). A daemon runs, contacts our backend, and writes /Library/Application Support/NetShield/state.plist with a valid dnsToken and other fields. The app NetShieldProxy.app is installed via a notarized, stapled Developer ID .pkg. The extension bundle is present at: /Applications/NetShieldProxy.app/Contents/Library/SystemExtensions/com.example.agent.NetShieldProxy.dnsProxy.systemextension. When I press Activate DNS Proxy in the UI, I see in the unified log: text NetShieldProxy: [com.example.agent:SystemExtensionActivator] Requesting activation for system extension: com.example.agent.NetShieldProxy.dnsProxy NetShieldProxy: [com.example.agent:SystemExtensionActivator] SystemExtensionActivator - activation failed: extension category returned error (domain=OSSystemExtensionErrorDomain code=9) NetShieldProxy: [com.example.agent:SystemExtensionActivator] SystemExtensionActivator - OSSystemExtensionError code enum: 9 NetShieldProxy: [com.example.agent:SystemExtensionActivator] SystemExtensionActivator - validationFailed And: bash systemextensionsctl list -> 0 extension(s) There is no prompt in Privacy & Security on this clean Mac. Question Given: The extension is packaged as a system extension (CFBundlePackageType = SYSX) with NSExtensionPointIdentifier = "com.apple.dns-proxy". Host and extension share the same Team ID and Developer ID Application cert. Entitlements on the target machine match the provisioning profile and Apple’s docs for DNS Proxy system extensions (dns-proxy-systemextension). This is happening on a clean Mac with no MDM profiles at all. What are the likely reasons for OSSystemExtensionErrorDomain error 9 (validationFailed) with "extension category returned error" in this DNS Proxy system extension scenario? Is there any additional configuration required for DNS Proxy system extensions (beyond entitlements and Info.plist) that could trigger this category-level validation failure? Any guidance or examples of a working DNS Proxy system extension configuration (host entitlements + extension Info.plist + entitlements) would be greatly appreciated. Thanks!

When installing a new version the app while a tunnel is connected, seemingly the old packet tunnel process gets stopped but the new one does not come back up. Reportedly, a path monitor is reporting that the device has no connectivity. Is this the expected behavior? When installing an update from TestFlight or the App store, the packet tunnel instance from the old tunnel is stopped, but, due to the profile being on-demand and incldueAllNetworks, the path monitoring believes the device has no connectivity - so the new app is never downloaded. Is this the expected behavior? During development, the old packet tunnel gets stopped, the new app is installed, but the new packet tunnel is never started. To start it, the user has to toggle the VPN twice from the Settings app. The tunnel could be started from the VPN app too, if we chose to not take the path monitor into account, but then the user still needs to attempt to start the tunnel twice - it only works on the second try. As far as we can tell, the first time around, the packet tunnel never gets started, the app receives an update about NEVPNStatus being set to disconnecting yet NEVPNConnection does not throw. The behavior I was naively expecting was that the packet tunnel process would be stopped only when the new app is fully downloaded and when the update is installed, Are we doing something horribly wrong here?

I want to know the right way/API/usage to use NWConnectionGroup to send both datagram and non-datagram stream. I am currently working on an P2P video streaming app. I want to leverage NWConnectionGroup over QUIC to handle both message channel (traditionally handled by a TCP connection) and media channel (traditionally handled by sth. over UDP) to transmit SRT packets back and forth. I created a NWConnectionGroup and it worked fine on non-datagram parts. The problems are with datagram part. I tried extracting a connection with datagram = true either from the group or from message, doesn't and in some cases it breaks other non-datagram connections. I currently send datagram directly using the NWConnectionGroup.send(content:completion). It kinda works but I keep seeing it canceled a lot of messages, which breaks SRT shortly after start. The warnings belong flooded my console. (Seems like want me to create a connection to transmit datagram, how?) nw_connection_create_with_connection [C1600] Original connection not yet connected nw_connection_group_create_connection_for_endpoint_and_parameters [G1] failed to create connection with parameters quic, local: fe80::439:68b4:6ec2:694%en0.60517, definite, attribution: developer, server I must use it in wrong way. What should I do to fix it?

I have an app that has been using the following code to down load audio files: if let url = URL(string: episode.fetchPath()) { var request = URLRequest(url: url) request.httpMethod = "get" let task = session.downloadTask(with: request) And then the following completionHandler code: func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didFinishDownloadingTo location: URL) { try FileManager.default.moveItem(at: location, to: localUrl) In the spirit of modernization, I'm trying to update this code to use async await: var request = URLRequest(url: url) request.httpMethod = "get" let (data, response) = try await URLSession.shared.data(for: request) try data.write(to: localUrl, options: [.atomicWrite, .completeFileProtection]) Both these code paths use the same url value. Both return the same Data blobs (they return the same hash value) Unfortunately the second code path (using await) introduces a problem. When the audio is playing and the iPhone goes to sleep, after 15 seconds, the audio stops. This problem does not occur when running the first code (using the didFinish completion handler) Same data, stored in the same URL, but using different URLSession calls. I would like to use async/await and not have to experience the audio ending after just 15 seconds of the device screen being asleep. any guidance greatly appreciated.

Hi everyone 👋 As a network engineer and indie iOS developer, I couldn’t find a lightweight mobile tool that fully supports IPv4/IPv6 dual-stack diagnostics — so I built NetToolbox -All-In-One Utility for engineers, DevOps, and developers. Here are its core features that solve real mobile networking pain points: One-Click Full Diagnostics: Integrates ping, traceroute, and multi-type DNS queries (A/AAAA/CNAME) — no need to switch between apps IPv4/IPv6 Dual-Stack Support: Seamlessly works in IPv6-only networks, with the ability to test connectivity differences between dual-stack environments LAN Device Scanning: Quickly identifies all devices on the same network segment and checks port availability Offline Functionality: Diagnostic logic is stored locally, enabling LAN troubleshooting without an internet connection Lightweight Design: 5MB install size, no storage bloat, and low power consumption during operation Dark Mode Support: Tailored for developers who work late at night During development, I leveraged Apple Intelligence alongside Claude Code and Gemini 3 to accelerate the process, optimize iOS native networking stack adaptation and local storage logic, and significantly boost development efficiency. I’d love to hear from the community: What must-have features are missing from mobile network diagnostic tools? Do you have experience optimizing iOS workflows with Apple Intelligence? 👉 You can try the app here: https://apps.apple.com/us/app/nettoolbox-all-in-one-utility/id6757392404 Feedback is highly appreciated — I’ll keep iterating to make it better! 🚀

Apple supports Wi‑Fi Aware, but it’s not clear what channel bandwidth Apple’s Wi‑Fi Aware uses. Is it 80 MHz or 40 MHz? Also, what is the channel bandwidth used by AirDrop?

Hello, is there a way to get MCC/MNC carrier codes on iOS? I'm also wondering if there's a private API. I want to obtain network information while I am abroad to determine the country of residence.

We've often observed connectivity issues from our VPN app that can only be remedied by removing the VPN profile. It happens to a small but significant amount of our users, this often happens more when the app is updated, but the VPN profile corruption can happen without that too. The behavior we're observing is that any socket opened by the packet tunnel process just fails to send any data whatsoever. Stopping and restarting the packet tunnel does not help. The only solution is to remove the profile and create a new one. We believe our app is not the only one suffering from this issue as other VPN apps have added a specific button to refresh their VPN profile, which seemingly deletes and re-created the VPN configuration profile. Previously, we've caught glimpses of this in a sysdiagnose, but that was a while ago and we found nothing of interest. Alas, the sysdiagnose was not captured on a device with the network extension diagnostic profile (it was not a developer device). I would love to get technical support with this, as our bug reports have gone unanswered for long enough, yet we are still struggling with this issue. But of course, there is no minimum viable xcodeproject that reproduces this. Is there anything we can feasibly do to help with this issue? Is it even an acknowledged issue?

Hey there Are there any recommendations or guidance for apps on alternatives to certificate pinning to secure their device network traffic? I want to move away from the overhead and risk associated with rotating certificates when using leaf pinning. However, I also don't want people to be able to perform a MITM attack easily using something like Charles Proxy with a self‑signed certificate added to the trust store. My understanding is that an app cannot distinguish between user‑trusted certificates and system‑trusted certificates in the trust store, so it cannot block traffic that uses user‑trusted certificates.

We have a Java application built for macOS. On the first launch, the application prompts the user to allow local network access. We've correctly added the NSLocalNetworkUsageDescription key to the Info.plist, and the provided description appears in the system prompt. After the user grants permission, the application can successfully connect to a local server using its hostname. However, the issue arises after the system is rebooted. When the application is launched again, macOS does not prompt for local network access a second time—which is expected, as the permission was already granted. Despite this, the application is unable to connect to the local server. It appears the previously granted permission is being ignored after a reboot. A temporary workaround is to manually toggle the Local Network permission off and back on via System Settings &gt; Privacy &amp; Security, which restores connectivity—until the next reboot. This behavior is highly disruptive, both for us and for a significant number of our users. We can reproduce this on multiple systems... The issues started from macOS Sequoia 15.0 By opening the application bundle using "Show Package Contents," we can launch the application via "JavaAppLauncher" without any issues. Once started, the application is able to connect to our server over the local network. This seems to bypass the granted permissions? "JavaAppLauncher" is also been used in our Info.plist file
