I'm seeing behaviour that I'm struggling to work out when making GraphQL related network requests (these are POST requests). I note that QA1941 covers the "lost connection" errors that I see in my responses, but I'd like to understand more, because just retrying the connection without understanding why I need to seems problematic. Here's the (partially redacted) logs I see when the error occurs: quic_conn_keepalive_handler [C69.1.1.1:2] [-0178f8467262b9e978791446c6629ddb66b2efc1] keep-alive timer fired, exceeding 2 outstanding keep-alives nw_read_request_report [C69] Receive failed with error "Operation timed out" nw_read_request_report [C69] Receive failed with error "Operation timed out" nw_read_request_report [C69] Receive failed with error "Operation timed out" nw_read_request_report [C69] Receive failed with error "Operation timed out" nw_read_request_report [C69] Receive failed with error "Operation timed out" 0x16264d818 69 stalled, attempting fallback Task <A6CC8D4D-83E1-4C61-96C7-BDDF2F04A35F>.<11> HTTP load failed, 1822/0 bytes (error code: -1005 [4:-4]) Task <3B0AAA67-3162-4F80-A930-D93F8A7EF1A4>.<12> HTTP load failed, 1823/0 bytes (error code: -1005 [4:-4]) nw_endpoint_flow_fillout_data_transfer_snapshot copy_info() returned NULL Task <A6CC8D4D-83E1-4C61-96C7-BDDF2F04A35F>.<11> finished with error [-1005] Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."

I have a pretty straightforward code to connect to a given ip address and port using NWConnection. On the first attempt to connect to the Local Network I see the "Local Network Privacy" dialog and sometimes if I press "Don't Allow" on that dialog everything starts to fail. No matter I do I keep receiving the following error: POSIXErrorCode(rawValue: 50): Network is down Obviously going to settings and allowing local network access to the app doesn't fix the issue. Neither deleting the app and installing it again. The only workaround I found is to restart my device which is unacceptable for a user. My code is really simple, I tried a lot of different approaches to connect but neither approach worked. I am on iOS 18. Is it a known bug? could be possible a bug on my code? Any idea would be really appreciated, thanks!

We want to ressolve dns for predefined sets of private app domains. We've added this rule: NENetworkRule(destinationHost: NWHostEndpoint(hostname: Private Domain1(example.com), port: 53), protocol: .UDP) As per apple documentation: A rule that matches all DNS queries/responses for hosts in the example.com domain. do you think it will work i.e it will forward DNS requests UDP flow to transparent provider in all the cases? or do you think the text is a bit misleading. it should instead say: "A rule that matches all DNS queries/responses for nameservers in the example.com domain"? This rule that look for port 53 of that domain only works if the system really asks a nameserver of that specific domain, right? So, what if a local DNS server or a different nameserver are taking care of the resolution?

So I have a small homebuilt device that has a simple Arduino-like chip with wifi capabilities (to be precise, the Xiao Seeed ESP32C, for anyone who cares), and I need my iOS app to talk to this device. Using the CoreBluetooth framework, we've had no problems --- except that in "noisy" environments sometimes we have disconnects. So we want to try wifi. We assume that there is no public wifi network available. We'd love to do peer-to-peer networking using Network, but that's only if both devices are from Apple. They're not. Now, the Xiao device can act as an access point, and presumably I could put my iPhone on that network and use regular TCP calls to talk to it. The problem is that my app wants to both talk to this home-built device, but ALSO make http calls to my server an amazon. So: how do I let my iOS app talk over wifi to this simple chip, while not losing the ability to also have my app reach a general server (and receive push notifications, etc.) To be more concrete, imagine that my app needs to be able to discover the access point provided by my device, use low-level TCP socket calls to talk to this local wifi device, all without losing the ability to also make general http calls and be just accessible to push notifications as it was before connecting to this purely local (and very short range, i.e. no more than 30 meters distant) device. Does this make sense? Have I explained it well enough?

Whenever I'm working on my content filter for macOS, I usually keep SIP disabled and with developer mode on (systemextensionsctl) as a convenience. The issue: content filter stopped receiving any kind of traffic when SIP is disabled. I don't see any log lines in Console for new flows, and the filter can't block anything, since it doesn't get any flows. Issue started yesterday. I tried several things and did some investigation, here are some findings: Reboot: rebooting did not fix the issue (while keeping SIP disabled). Reenabling SIP fixes the issue for both App Store and Xcode builds. Code: latest published version also stopped working with SIP disabled. This version is stable and confirmed to work as reported by users. Clean Xcode + rebuild did not fix the issue. Lastly, I inspected the logs and did not see any errors standing out. I noticed the filter does get started (startFilter is called) and registered, but after that there are no errors/new flows or anything, just silence (logs below). com.apple.networkextension default 15:22:22.270746-0300 : Calling startFilterWithCompletionHandler com.extension.MyExtension info 15:22:22.270998-0300 Success applying filter settings com.apple.networkextension debug 15:22:22.272705-0300 NESMFilterSession[My Extension:B9F3F30E-E0E0-4E53-8B32-EFC285E3CF6A]: Checking providerBundleIdentifier com.extension.MyExtension for pluginClass 4 com.apple.networkextension debug 15:22:22.272717-0300 Checking for com.extension.MyExtension - com.apple.networkextension.filter-data com.apple.networkextension default 15:22:22.272728-0300 Found 1 registrations for com.extension.MyExtension (com.apple.networkextension.filter-data) com.apple.networkextension debug 15:22:22.272778-0300 NESMFilterSession[My Extension:B9F3F30E-E0E0-4E53-8B32-EFC285E3CF6A]: com.extension.MyExtension is registered for pluginClass 4 Here are some additional info about my system: macOS 15.1 Between yesterday and today, the only new Installation is XProtectPlistConfigData at 12:10AM Thanks!

Hi, TLDR: On iOS, when my PacketTunnel is running, can I exclude DNS requests from going into the tunnel? I have a test app, using Apple's AsyncDNSResolver, that makes a DNS call and it works when the tunnel is not running. If the tunnel is running it times out after 30 seconds and I get the error -65568. Here's how I'm setting up the tunnel func setup(tunnelRemoteAddress: String) { let settings = NEPacketTunnelNetworkSettings(tunnelRemoteAddress: tunnelRemoteAddress) settings.ipv4Settings = NEIPv4Settings(addresses: [tunnelRemoteAddress], subnetMasks: ["255.255.255.255"]) settings.ipv4Settings?.includedRoutes = [NEIPv4Route.default()] let proxySettings = NEProxySettings() proxySettings.httpEnabled = true proxySettings.httpServer = NEProxyServer(address: ProxyServerConfiguration.host, port: ProxyServerConfiguration.port) proxySettings.httpsEnabled = true proxySettings.httpsServer = NEProxyServer(address: LocalProxyServerConfiguration.host, port: LocalProxyServerConfiguration.port) proxySettings.excludeSimpleHostnames = true proxySettings.exceptionList = nil let dnsSettings = NEDNSSettings(servers: ["8.8.8.8"]) settings.dnsSettings = dnsSettings settings.proxySettings = proxySettings setTunnelNetworkSettings(settings) { error in // ... } } I've tried all combinations of setting/excluding the NEDNSSettings but the DNS call always fails when the tunnel is running. Thanks for any help.

On iOS beta, monitoring network usage using the getifaddrs API sporadically causes system volume spikes. This happens even though the application does not interact with any audio-related code. The issue persists across different polling intervals (e.g., 0.05s to 1s) and only occurs when invoking getifaddrs. Replacing the API calls with mock data eliminates the problem, suggesting a potential issue with getifaddrs in the beta environment. The application updates UI elements based on network activity, but the volume spikes occur independently of UI or other observable app behavior. Steps to Reproduce: Create an app that monitors network usage using the getifaddrs API. Fetch network statistics on a timer (e.g., every 0.05 seconds). Observe system behavior while running the app on iOS beta. Note sporadic volume spikes during app runtime. Expected Result: Polling network usage with getifaddrs should not affect system volume or other unrelated resources. Actual Result: System volume spikes occasionally when network statistics are retrieved using getifaddrs. iOS 18.2 Beta, Tested on physical device ( iPhone 15 Pro )

Hi, On macOS 15 beta 7, we get a network popup while launching application, "Allow "App" to find the devices on local network?" This popup we are not seeing in older versions of macOS. We also see a a new option in "System Settings->Privacy & Security->Local Network". Is there way to add the application entry in "Local Network" through a command so that we can suppress this popup on launching the applications? Regards Prema Kumar

I'm unable to set the "secure" property of HTTPCookieProperty (for initializing HTTPCookie) to false. tried: .secure: "FALSE" .secure: "false" .secure: false but all of above resulted in "cookie.isSecure" being true. The only thing that worked was not providing the field at all (which made the property default to false). Seems like a niche bug?

Hi Team, OS is prompting for local network permission for our application which runs as root level daemon. As per the our analysis, it looks like it is prompting from our own library which is trying to get network info ' using /usr/sbin/system_profiler with "-xml -detailLevel basic SPNetworkDataType" and then trying to iterate to find DNS.ServerAddresses for each item. Then using [NSHost hostWithAddress:IPAddress];(When this library is not linked to the app then there is no prompt, so most likely this is the code that is resulting in the prompt). Is this expected ? . Is there any other way that we can get DNS host name without being prompted for local network permission on mac OS 15

Hey,I want to get nearby Wi-Fi network's SSID into the app using network extension framework.Right now I can get scan list by visiting the setting---&amp;gt;Wifi Screen but I want to get those Scan Result into the app without visiting the setting wifi screen.If anyone idea about it please let me know

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 all, I have a question, I am developing an application that uses the apply() function of the NEHotspotConfigurationManager class to switch the Wifi of the device. In the completionHandler of the apply() function, the error argument contains “Internal Error(8)” and the wifi switching may fail. We have never seen this problem during development, and since it occurs only in the market, we are at a loss as to the cause and countermeasure. Do you know the cause of the “Internal Error(8)” and how to fix it? A similar phenomenon has already been discussed in the following thread, but after countermeasures were taken in iOS12, it also occurs in iOS13 and later and no progress has been made since then. https://developer.apple.com/forums/thread/107851 I would appreciate it if someone could clarify what is happening with this error, as there is not much information on the web regarding this error. Thank you in advance.

Is it possible to build an iOS app with the purpose of content filtering? I'll give an example. This app would block access to example.com, therefore if I were on the Safari or any iOS compatible browser, if I were to try to navigate to example.com access would be blocked. The same would happen if I were on let's say Instagram and it attempted to make an outbound api call to example.com, that too would fail. Is this device wide content filtering possible on the iOS platform? Furthermore would you be able to implement redirect logic. As in the user tries to visit example.com but it is redirected to google.com?

Ex Windows programmer trying to evolve to Mac... please go easy. :-) As part of my transition I'm trying to get some older stuff I wrote for myself to work. I have a command line utility program which uses socket(), connect(), send(), select/recv() to create a RAW socket and send a ICMP_ECHO packet to a host and then await its return. Essentially, PING with some minor variation in its output. Got it built in Xcode. Found that socket() with SOCK_RAW failed until I ran as root (via SUDO). OK, no problem. Now it sends, but it never receives a response. The select() always times out rather than receiving the reply. When I run my Windows cmd line version on the same machine under Parallels, it works fine. So I'm confident the other host is able to be reached from my network, etc. I can use actual PING from the command line just fine too. Is there some other permission facility in MacOS that would prevent me from receiving the reply packets? What would it be called, how would I either turn it off or work with it? Thanks for any help!

I am planning to implement Peer to Peer data exchange between 2 iOS devices. I have the following queries. My devices are connected through Ethernet. I would prefer to use this route if possible before switching over to Wifi. I can see there is an option to use prohibitedInterfaceTypes but that doesn't guarantee the route to use Ethernet when there are multiple available. Does the connection automatically switch between ethernet and Wifi or does that have to be handled via isViable and betterPathAvailable? I'm unsure when I should be using a custom framing protocol. I just need to exchange codable objects between the devices. Is the custom protocol required only if I use TCP as the underlying protocol? Can NSURLSessionStreamTask be used for this use case?

Kindly suggest the best approach for the below requirement. Requirement Summary: I have a camera that generates its own Wi-Fi network with some specifications, and I need my iOS app to automatically connect to that Wi-Fi whenever it's in range. This Wi-Fi network is used for transferring files between the camera and the iOS app and to give commands to camera to do certain actions. This Wi-Fi does not provide internet access. Details: The iOS app should automatically connect to the camera's Wi-Fi network once it launches. The camera's Wi-Fi does not have internet access; it is purely for file transfers (e.g., photos/videos) between the camera and the iOS app and to command camera to do certain actions The iOS device should still use mobile data for internet access while connected to the camera's Wi-Fi. The mobile data will be used to upload files to the cloud, as I have a large data plan available for internet use. The app should maintain the connection to the camera's Wi-Fi as long as the iOS device is within proximity of the camera. If the device moves out of range and then comes back, the iOS app should prefer and reconnect to the camera's Wi-Fi over any other available networks. I am looking for a solution or approach that can make this seamless, ensuring a stable connection between the camera and the iOS app while prioritizing mobile data for internet connectivity.
