Hello eveybody,Currently I'm working on an app which connects to a device. During testing I encounter an internal error of NEHotspotConfigurationErrorDomain. See the log snippet:Domain=NEHotspotConfigurationErrorDomain Code=8 "internal error." UserInfo={NSLocalizedDescription=internal error.}This error appears randomly. In one day I encountered it three times. The only solution I can think of is catching this error somehow and then telling the user to restart the device.After this error appears, the wifi functionality of iOS in all third party apps seems to be broken. Only restarting helps as far as I know. Also there seems to be nothing we as app developers can do about it. Therefor I wonder if there is some way to prevent this error somehow? The only solution I can think of is catching this error somehow and then telling the user to restart the device.Also since there is not much information about this error on the web, it would be really nice if someone can clarify whats going on with this error.Regards.

Hi,
I am working on a use case where I want to read the wifi signal strength data in the terms of RSSI (Received Signal Strength Indicator) values (or) any other way of representation. when my iPhone is connected to the wifi and Move around the house.
Is this use case possible ? If yes, what are all the entitlements that I have to obtain?
I have some concerns related to shortening the lifetime of certificates, as per
https://support.apple.com/en-gb/102028
Does this apply to Private CA root certificates?
And if yes:
does it apply if I use ATS and higher level API like URLSession
does it apply it I carry my root CA cert in my app payload and use low level libraries without ATS support?
Hi everyone,
We are working on creating a virtual network interface using NEPacketTunnelProvider, with an MTU of 1500 bytes.
I would like to understand what will happen if we attempt to write packets of approximately 65,000 bytes to this interface. Specifically, will the packets be fragmented based on protocol and flags, will they be dropped, or is there another unexpected behaviour we should anticipate?
Thanks

I recently encountered an issue with incorrect progress reporting and timeout behavior when using NSURLSession to upload small data buffers.
Background
In my app, I split a large video file into smaller 1MB chunk files for upload. This approach facilitates error retries and concurrent uploads. Additionally, I monitor the upload speed for each request, and if the speed is too slow, I switch CDNs to re-upload the chunk.
Issue Description
When using NSURLSessionUploadTask or NSURLSessionDataTask to upload a 1MB HTTP body, I noticed that the progress callbacks are not accurate. I rely on the following callback to track progress:
- (void)URLSession:task:didSendBodyData:totalBytesSent:totalBytesExpectedToSend:
Even when using Network Link Conditioner to restrict bandwidth to a very low level, this callback reports identical values for totalBytesSent and totalBytesExpectedToSend right at the start of the request, indicating 100% upload progress. However, through network traffic inspection, I observed that the upload continues slowly and is far from complete.
Additionally, I noticed that even though the upload is still ongoing, the request times out after the duration specified in - NSURLSessionConfiguration.timeoutIntervalForRequest. According to the documentation:
"The request timeout interval controls how long (in seconds) a task should wait for additional data to arrive before giving up. The timer associated with this value is reset whenever new data arrives."
This behavior suggests that the timeout timer is not reset as the document says during slow uploads, likely because didSendBodyData is not updating as expected.
Consequently, the timer expires prematurely, causing 1MB chunks to frequently timeout under slow network conditions. This also prevents me from accurately calculating the real-time upload speed, making it impossible to implement my CDN switching strategy.
Some Investigation
I have found discussions on this forum regarding similar issues. Apple engineers mentioned that upload progress is reported based on the size of data written to the local buffer rather than the actual amount of data transmitted over the network. This can indeed explain the behaviour mentioned above:
https://developer.apple.com/forums/thread/63548
https://developer.apple.com/forums/thread/746523
Interestingly, I also noticed that progress reporting works correctly when uploading to some certain servers, which I suspect is related to the TCP receive window size configured on those servers. For example:
Accurate progress: https://www.w3schools.com
Inaccurate progress: Most servers, like https://developer.apple.com
I created a sample project to demostrate the progress & timeout issues and different behaviours when uploading to some servers:
https://github.com/Naituw/NSURLSessionUploadProgressTest
Questions
Is there any way to resolve or workaround this issue?
Like adjusting the size of the local send buffer?
or configuring NSURLSession to report progress based on acknowledged TCP packets instead of buffer writes?
Or are there any alternative solutions for implementing more accurate timeout mechanisms and monitoring real-time upload speed?

I am looking for a lightweight server that can run inside an app.
The key requirement is that it must support local IP communication over HTTPS.
I have searched Google and found several frameworks, but as far as I know, support for HTTPS in this environment has been discontinued or is no longer available.
If anyone knows a solution that meets these criteria, I would greatly appreciate your guidance.
Thank you in advance!😀

I created a self signed CA and use it to generate/sign a client cert using openssl. Then I use the self signed client cert to do TLS client authentication with my server (which also uses the self signed CA). The issue I have is when I validate the self signed CA, by calling SecTrustEvaluateAsyncWithError, it always complains this error “'DigiCert Global Root G3' certificate is not trusted". However that CA (DigiCert Global Root G3) is not my self signed CA (my CA is 'MQTTSampleCA' and I attached a dump of the my CA cert in the PR in the end of this post), so I'm confused why the API keeps complaining that CA. After some researching, I see that is a well known CA so I download its cert from https://www.digicert.com/kb/digicert-root-certificates.htm, install and trust it on my iOS device, but that doesn't help and I still get the same error. I provide all the repro steps in this PR: https://github.com/liumiaojq/EmCuTeeTee/pull/1, including how I generate the certs and the source codes of a test app that I used to do cert validation. I appreciate if anyone can share insights how to resolve this error.
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)
}
}
}
}
Hi, I am working on a case in our organisation where hundreds if not a thousand wireless network clients are affected by regular, usually 30 sometimes 60 minute sometime they are unnoticeable but often people having meetings notice that a lot.
We excluded wireless network configuration issue since disconnections happens to clients both connected to Cisco and Ubiquiti Access Points.
WLC logs mostly show EAP timeout errors - clients are getting disauthenticated and authenticated back - usually without any action needed - but the meeting is being interrupted.
What I found in Macbook logs with sudo log show [options] is the main reason of network disconnection:

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

Hi, I’m working on a case in our organisation where we encounter regular wireless network disconnections - 30 and 60 minutes. ~ 1800 sec session is widely seen across hundreds if not thousand Macbooks.
We excluded internal wireless configuration issue and vendor specific problem as the disconnections happen on both Cisco and Ubiquiti Access Points.
Wireless Controller debugging most often show EAP timeout error.
Sniffer shows that the disassociation is initiated by Macbook.
MacOS logs show wifianalyticsd performing some actions before the disconnection (generated with sudo log show --debug [time]):

Hey!
We are investigating a problem pf rules being ignored by some processes. Despite blocking all traffic, some outgoing unicast packets can be seen in tcpdump. Issue is present in MacOS 15.0.0 - 15.3.1 (Newest at the time of writing). I tested MacOS 14.7.4 and pf rules there behaved as expected. Steps to reproduce the issue:
$ cat pf.conf
block all
$ sudo pfctl -e -F all -f ./pf.conf
Password:
pfctl: Use of -f option, could result in flushing of rules
present in the main ruleset added by the system at startup.

Hello, I'm having some problems starting my DNS proxy network extension.
Even after I call NEDNSProxyManager.saveToPreference() successfully I don't see any logs from my dns proxy.
This is the code from the user space app:
import SwiftUI
import NetworkExtension
func configureDNSProxy() {
let dnsProxyManager = NEDNSProxyManager.shared()
dnsProxyManager.loadFromPreferences { error in
if let error = error {
print("Error loading DNS proxy preferences: \(error)")
return
}
dnsProxyManager.localizedDescription = "my DNS proxy"
let proto = NEDNSProxyProviderProtocol()
proto.providerBundleIdentifier = "com.myteam.dns-proxy-tests.ne"
dnsProxyManager.providerProtocol = proto
// Enable the DNS proxy.
dnsProxyManager.isEnabled = true
dnsProxyManager.saveToPreferences { error in
if let error = error {
print("Error saving DNS proxy preferences: \(error)")
} else {
NSLog("DNS Proxy enabled successfully")
}
}
}
}
@main
struct dns_proxy_testsApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
init() {
configureDNSProxy()
}
}
This is the code for my network extension(DNSProxyProvider.swift):
import NetworkExtension
class DNSProxyProvider: NEDNSProxyProvider {
override func startProxy(options:[String: Any]? = nil, completionHandler: @escaping (Error?) -> Void) {
NSLog("dns proxy ne started")
completionHandler(nil)
}
override func stopProxy(with reason: NEProviderStopReason, completionHandler: @escaping () -> Void) {
NSLog("dns proxy ne stopped")
completionHandler()
}
override func sleep(completionHandler: @escaping () -> Void) {
NSLog("dns proxy ne sleep")
completionHandler()
}
override func wake() {
NSLog("dns proxy ne wake")
}
override func handleNewFlow(_ flow: NEAppProxyFlow) -> Bool {
NSLog("dns proxy ne flow")
return true
}
}
The bundle identifier for my network extension is: com.myteam.dns-proxy-tests.ne and both the user space app and the network extension have the DNS Proxy capability. Both have the same app group capability with the same group name group.com.myteam.dns-proxy-test.
The info.plist from the network extension look like this(I didn't really modify it from the default template created by xcode)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

excludeAPNs = YES
excludeDeviceCommunication = YES
enforceRoutes = NO
pluginType = com.myteam.dns-proxy-tests
providerBundleIdentifier = com.myteam.dns-proxy-tests.ne
designatedRequirement = identifier "com.myteam.dns-proxy-tests.ne" <...> /* exists */
}
}
}
But then I see:
Checking for com.myteam.dns-proxy-tests.ne - com.apple.networkextension.dns-proxy
But then finally
Found 0 registrations for com.myteam.dns-proxy-tests.ne (com.apple.networkextension.dns-proxy)
So I think that last log probably indicates the problem.
I'm a bit lost at what I'm doing wrong so I'd be super thankful for any pointer!
Feedback Ticket: FB13812251
Problem Statement: We are currently facing internet connectivity issue with our VPN application where we try to disconnect the VPN from the Packet Tunnel Network Extension using - (void)cancelTunnelWithError:(nullable NSError *)error. Which API to use to disconnect the VPN from Packet Tunnel as VPN app is not running such that device retains its internet connectivity as soon as VPN disconnects.
Configuration: We have configured PacketTunnelProvider with the following settings:
(NETunnelProviderManager *)tunnelProvider.protocolConfiguration.includeAllNetworks = YES;
(NETunnelProviderManager *)tunnelProvider.protocolConfiguration.excludeLocalNetworks = NO;
(NETunnelProviderManager *)tunnelProvider.protocolConfiguration.enforceRoutes = NO;
These settings are applied from the VPN app and allow us to successfully establish a VPN connection, with all traffic being routed through the tunnel as expected.We are setting above properties to address local net attack.
Issue we are facing:
However, we encounter a problem when we attempt to disconnect the VPN from. When we call the following method from PacketTunnel network extension:
(void)cancelTunnelWithError:(nullable NSError *)error
Upon calling this method, the VPN disconnects as expected, but the device loses all internet connectivity and is unable to access any resources. This is not the desired behavior.
Observation : Interestingly, when we call the following method from the app side. The VPN disconnects and the device retains its internet connectivity.
[enabledConfig.connection stopVPNTunnel];
We would like to achieve the same behavior when disconnecting the VPN from the Network Extension. So we are looking for an API that could be called from NE without causing any internet connectivity issue.
Any guidance on how to resolve this issue would be greatly appreciated.
We use URLSessionWebSocketTask for web socket connection. When get error we reconnect - recreate new URLSessionWebSocketTask.
Test case: off wifi on iOS device; get error(s) URLError.notConnectedToInternet. When on wifi correct create new task with connect.
This working on iOS 12, 14, 15, 16, 17. But on iOS 18 we get error URLError.notConnectedToInternet without correct connection.
class WebSocketManager {
...
func openConnection() {
webSocketTask?.cancel(with: .goingAway, reason: nil)
webSocketTask = urlSession?.webSocketTask(with: urlRequest)
webSocketTask?.resume()
listen()
}
func closeConnection() {
webSocketTask?.cancel(with: .goingAway, reason: nil)
webSocketTask = nil
}
private func listen() {
webSocketTask?.receive { [weak self] result in
guard let self else { return }
switch result {
case .failure(let error):
delegate?.webSocketManager(self, error: error)
case .success(let message):
switch message {
case .string(let text):
delegate?.webSocketManager(self, message: .text(text))
case .data(let data):
delegate?.webSocketManager(self, message: .data(data))
@unknown default:
fatalError()
}
listen()
}
}
}
}
Delegate:
func webSocketManager(_ webSocketManager: WebSocketManagerType, error: Error) {
webSocketManager.openConnection()
}
Didn't get any response last time so reposting my query. I know procID is of no use in IOS but just for curiosity I am logging proc ID in control Filter and data Filter.
I was trying to log the flow description using control filter and data filter. But when I am trying to log the proc ID in control filter, it is always 0, but in data filter, it logs some value. Same goes with the eproc ID. I want to use the flow description data in some other target so I will be sending the data using sockets and I cannot share data from data filter due to its restrictions and control filter isn't providing the proc ID. What should I do?
Context: I work on Home Assistant App, a smart home platform which connects locally to their smart home server. The Apps essentially needs the local network permission and every single user gives the permission, but some in macOS 15.3 are reporting that even though the permission is given, the app still reports it is not, and logs also confirm that.
Since there is no way to reset local network permission on macOS I am kind of on a dead end here.
How can the user get out of this situation?
I also read https://developer.apple.com/forums/thread/763753?answerId=824036022&replyId=824036022 and the TN3179 but still no solutions for my case.
We have an app which is using CTSubscriber.simInserted (using the carrier entitlement com.apple.CommCenter.fine-grained).
In iOS 18, simInserted returns false for every sim (where it should instead be returning true).
Presumably this just is a temporary bug in 18 beta?
I was trying to fetch inBytes and outBytes in content filter. Each time it is logging 0 as inByte and outByte in handleNewFlow flow description. How to get inByte and outByte of the flow?
Hi,
We are developing an app using PacketTunnelProvider from Network Extension framework. It is packaged as a system extension.
We are trying to implement an "always-on" functionality, but cannot manage to start the extension before user login, with or without on-demand enabled.
However we see in other posts (1, 2) that a network extension packaged as sysex should automatically start before user login.
Are we missing something? Is it a limitation of PacketTunnelProvider?
Thanks
