Hi all! I’m having trouble distributing an iOS app with a DNS Proxy NetworkExtension via AdHoc. The app and extension work perfectly with development profiles, but when I export and install the AdHoc IPA, I get a “permission denied” error when trying to install/enable the DNS Proxy extension. What I’ve done: Both the app and the DNS Proxy extension have their own App IDs in the Apple Developer portal. Both App IDs have the same App Group enabled: group.com.irakai.SafeLinkApp2. The extension App ID has the NetworkExtension capability with dns-proxy enabled. I created two AdHoc provisioning profiles (one for the app, one for the extension), both including the same devices and the correct entitlements. I assigned the correct AdHoc profiles to each target in Xcode and exported the IPA via Organizer. I install the IPA on a registered device using Apple Configurator. Entitlements (extracted from the signed binaries on device): App: <key>application-identifier</key><string>6PBG234246.com.irakai.SafeLinkApp2</string> <key>com.apple.developer.networking.networkextension</key><array> <string>packet-tunnel-provider</string> <string>dns-proxy</string> </array> <key>com.apple.developer.team-identifier</key><string>6PBG234246</string> <key>com.apple.security.application-groups</key><array> <string>group.com.irakai.SafeLinkApp2</string> </array> <key>get-task-allow</key><false/> DNSProxy Extension: <key>application-identifier</key><string>6PBG234246.com.irakai.SafeLinkApp2.DNSProxy</string> <key>com.apple.developer.networking.networkextension</key><array> <string>dns-proxy</string> </array> <key>com.apple.developer.team-identifier</key><string>6PBG234246</string> <key>com.apple.security.application-groups</key><array> <string>group.com.irakai.SafeLinkApp2</string> </array> <key>get-task-allow</key><false/> Error message (from my app’s logs): Error instalando DNS Proxy: permission denied Usuario: Roberto AppGroup: group.com.irakai.SafeLinkApp2 AppGroupPath: /private/var/mobile/Containers/Shared/AppGroup/D8AD2DED-AD96-4915-9B7A-648C9504679B Entitlements: BundleId: com.irakai.SafeLinkApp2 Debug info: Error Domain=NEDNSProxyErrorDomain Code=1 "permission denied" UserInfo={NSLocalizedDescription=permission denied} Other details: The device is included in both AdHoc profiles. The App Group is present and identical in both entitlements. The extension’s bundle identifier matches the App ID in the portal. The extension is signed with the correct AdHoc profile. I have tried rebooting the device and reinstalling the IPA. The error only occurs with AdHoc; development builds work fine. Questions: Is there anything else I should check regarding AdHoc provisioning for NetworkExtension DNS Proxy? Are there any known issues with AdHoc and NetworkExtension on recent iOS versions? Is there a way to get more detailed diagnostics from the system about why the permission is denied? Could this be a bug in iOS, or am I missing a subtle configuration step? Any help or suggestions would be greatly appreciated. Thank you!

Hi everyone, I'm developing an enterprise iOS application and need to access the WiFi connection channel. I understand that Apple's privacy and security policies restrict direct access to certain network details, including the WiFi connection channel. After some research, I found that this data might be accessible via the private API MobileWiFi.framework. However, when I tried to use this framework, I encountered the following error: Missing com.apple.wifi.manager-access entitlement I reached out to Apple regarding this entitlement, but they were not familiar with it, suggesting it might be deprecated. Here are my questions: Is there an official or supported way to access the WiFi connection channel in an enterprise iOS app? If not, is there any workaround or additional steps required to use the MobileWiFi.framework without encountering the entitlement error? Are there any specific entitlements or provisioning profile configurations that I need to be aware of to resolve this issue? Any guidance or suggestions would be greatly appreciated. Thank you!

I am seeking clarification regarding the capabilities and limitations of deploying content filter profiles, such as web content filters, on unsupervised iOS devices through MDM solutions. Specifically, is per-app content filtering supported on unsupervised devices, or is it restricted to supervised devices only? If such restrictions exist, are there recognized workarounds? Additionally, I would like to understand if there are specific permissions or entitlements that enable apps to perform advanced filtering or monitoring functions on unsupervised devices. Any guidance or references to official documentation would be greatly appreciated.

I am trying to commission an ESP32-H2 Matter device using the chip-tool. It's running the Light Switch sample. I can commissioning it using the iOS Home App, so I know the code on it's working okay. I would like to understand more about the Fabric process, so I'd like to use the Home Pod powered Thread network rather than setting up an instance of Open Thread Border Router. I have created a simple iOS app and can fetch the activeOperationalDataSet from the Preferred network using func obtainPreferredNetworkCredentials() async -> (Void) { let client = THClient() let bIsPreferredAvailable = await client.isPreferredAvailable() if bIsPreferredAvailable == true { var credential: THCredentials? do { credential = try await client.preferredCredentials() if let dataset = credential?.activeOperationalDataSet { print(dataset.hexDescription) } } catch { print("Failed to get the credentials") } } } The hexDescription comes from this extension extension Data { var hexDescription: String { return reduce("") {$0 + String(format: "%02x", $1)} } } I am decoding the Data and displaying it as a hex string. It looks something like this: 0e080000000000000000000300001935060004001fffc002089f651677026f48070708fd9f65167702000ee90914b5d1097de9bb0818dc94690c0402a0f7f8 However, when I attempt to commission the device, it fails during ThreadSetup. Googling the issue says most likely the Operational Dataset is wrong in some way. Before I spend too much time on this, I want to make sure I'm doing the right thing in terms of getting the Operational Dataset to use with the chip-tool. Any help is appreciated!

I'm able to discover a service with Bonjour, which gets me an nw_browse_result_t from which I can get an nw_endpoint_t and then an nw_connection_t. That's all fine. But this particular service runs on 3 ports. The port numbers of the other 2 ports are in the txt record (but they are well-known and stable anyway). How can I create 2 more nw_connection_t to the same host/IP but on a different port? I already have this working with NSNetService, but am trying to update to Network.framework. I've found nw_endpoint_get_address() but the docs say it returns null "if the endpoint is not of type nw_endpoint_type_address" and indeed nw_browse_result_t gives me an nw_endpoint_type_bonjour_service.

Question: Best Practice for NEFilterRule and NENetworkRule Initializers with Deprecated NEHostEndpoint? Hi all, I'm looking for guidance on the right way to construct an NEFilterRule that takes a NENetworkRule parameter. Reading the latest documentation, it looks like: All initializers for NENetworkRule that accept an NEHostEndpoint are now deprecated, including initWithDestinationHost:protocol: and those using the various *Network:prefix: forms. NEHostEndpoint itself is also deprecated; Apple recommends using the nw_endpoint_t type from the Network framework instead. However, NEFilterRule still requires a NENetworkRule for its initializer (docs). With all NENetworkRule initializers that take NEHostEndpoint deprecated, it’s unclear what the recommended way is to create a NENetworkRule (and thus an NEFilterRule) that matches host/domain or network traffic. What’s the proper way to construct these objects now—should we create the endpoints using nw_endpoint_t and use new/undocumented initializers, or is there an updated approach that’s considered best practice? Helpful doc links for reference: NEFilterRule docs NENetworkRule docs NWHostEndpoint (now deprecated)

I'm using NETransparentProxyProvider to intercept udp sockets using the method handleNewUDPFlow. An application may create a UDP socket and set the DONTFRAG using setsockopt method setsockopt(s, IPPROTO_IP, IP_DONTFRAG, &val, sizeof(val)) In this case, do I have option in this case, to get the connection settings inside the callback (void)handleNewUDPFlow:(NEAppProxyUDPFlow *)flow initialRemoteEndpoint:(NWEndpoint *)remoteEndpoint; So in this case, I would be able to create the outgoing socket with the exact same characteristics, after the original app socket got intercepted by my proxy provider ?

Our application currently uses NEFilterPacketProvider to filter network traffic based on Layer 4 rules (5-tuple: source IP, destination IP, source port, destination port, and protocol) on a packet-by-packet basis. We now want to extend this filtering to also consider the associated process—for example, allowing traffic from a specific source IP to a destination IP and port only if it's associated with a specific local process. That is, we’d like to make filtering decisions not just based on the 5-tuple, but also on the identity of the process either sending or receiving the traffic. We’ve looked into NEFilterSocketProvider, which does expose Layer 7 information such as process identifiers. However, it doesn’t seem to be tightly synchronized with the packet flow handled by NEFilterPacketProvider. As a result, there’s a risk that we might only get process information after the TCP handshake is complete, or before the socket is fully bound—at which point some of the 5-tuple fields (such as the local port) may still be unavailable. What we need is a way to correlate the 5-tuple with the relevant process name (either sender or receiver) at the time the first packet—e.g., a SYN packet—is about to be sent or received. Is there a recommended way to achieve this kind of early, process-aware filtering using NetworkExtension APIs?

Hi, I am making a AI-Powered app that makes api requests to the openai API. However, for security, I set up a vercel backend that handles the API calls securely, while my frontend makes a call to my vercel-hosted https endpoint. Interestingly, whenever I try to make that call on my device, an iPhone, I get this error: Task <91AE4DE0-2845-4348-89B4-D3DD1CF51B65>.<10> finished with error [-1003] Error Domain=NSURLErrorDomain Code=-1003 "A server with the specified hostname could not be found."

Running my endpoint on terminal with curl also works as intended, as I see api key usages. But for some reason, on my project, it does not work. I've looked through almost every single post I could find online, but a lot all of the solutions are outdated and unhelpful. I'm willing to schedule a call, meeting, whatever to resolve this issue and get help more in depth as well.

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?

Hi everyone, I’m developing an app called FindMyNet that allows users to find the best internet provider based on their postal code (CAP). The app is built with Xcode and the macOS simulator. I’ve set up a FastAPI backend that communicates with an Excel database containing internet provider data for each postal code. Unfortunately, when I try to run the app, I encounter an error that prevents me from retrieving data from the database and displaying the correct provider. Task <6B5C86B6-181A-4235-AE68-23AAF6645683>.<1> finished with error [1] Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" UserInfo={_NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <6B5C86B6-181A-4235-AE68-23AAF6645683>.<1>, _kCFStreamErrorDomainKey=1, _kCFStreamErrorCodeKey=1, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask <6B5C86B6-181A-4235-AE68-23AAF6645683>.<1>" ), _NSURLErrorNWPathKey=satisfied (Path is satisfied), interface: en0[802.11], ipv4, dns, uses wifi} Problem description: • The FastAPI backend is running on a Raspberry Pi and communicates with the app via an HTTP request. • When I enter a postal code, the app should return the best provider for that region, but I only get a 500 error. • I’ve verified that the FastAPI server is running, but it seems there’s an issue with communication between the app and the server. Steps taken so far: • I’ve checked the logs on the FastAPI server, but there are no obvious errors. • I’ve manually tested the API using Postman, and it works fine, so the issue seems to be app-side. Support request: I’d like to understand better what could be causing this error and if anyone has had similar experiences. Any advice on diagnosing the problem or solutions for resolving it would be greatly appreciated. Thanks in advance for your help!

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

Hi all, I’m developing a companion iOS app that connects to a device-created Wi-Fi hotspot to transfer videos or other files WebSocket. The challenge is: once the iPhone connects to this hotspot, it loses internet access because iOS routes all traffic through Wi-Fi. However, I’d like to keep the iPhone’s cellular data active and usable while staying connected to the local hotspot — so the app can access cloud APIs, or the user can continue using other apps that require internet access. I understand that iOS prioritizes Wi-Fi over cellular, but are there any supported workarounds or patterns (e.g., MFi programs, local-only Wi-Fi access, NEHotspotConfiguration behavior, etc.) that : • Using Wi-Fi only for local communication; • cellular to remain active for internet access. Any insights or Apple-recommended best practices would be greatly appreciated — especially any official references regarding MFi Accessory setup or NEHotspotConfiguration behavior in this context. Thanks in !

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 trying to programmatically block some egress and ingress connections using bsd packet filters. My program writes rules in a file and this file is loaded using an anchor in /etc/pf.conf (main ruleset) . Rules work as intended. But when there is network change like turn on/off wifi , and change in wifi nw the main ruleset is getting flushed and i have to reapply (pfctl -q -f /etc/pf.conf) to get the rules back in place. Looking for guidance to keep the main ruleset intact irrespective of system changes.

Using NEHotspotConfigurationManager.joinAccessoryHotspot(_ accessory: ASAccessory, passphrase: String) to connect the WiFi, but this function implicitly sets joinOnce to YES. Is there any api that can use ASAccessory to connect to WiFi while maintaining JoinOnce = false. Is it possible to open up this feature？

WiFi and Bluetooth are both enabled on Mac and iPhone, neither device is connected to a network Running MultipeerConnectivity on the Mac as Advertiser and iPhone as Browser, the invitation is sent from the phone and accepted by the mac, but the connection is then dropped. This doesn’t happen when the Advertiser is another iOS device. STEPS TO REPRODUCE THE PROBLEM We have created a small sample project that demonstrates the problem. It can be found at: https://github.com/eidria/Multipeer-Progress-Demo.git. It contains both a Mac app and a iOS app. Run the Mac app and start Advertising Run iOS app and start Browsing The iOS app automatically issues an invitation to the browser (Mac) which accepts. Shortly after the connection is dropped.

I have few API's written with URLSession. Will they work in Carrier-constrained network / satellite mode ?

I use eapolcfg in Apple's open source eap8021x repository to connect to the enterprise network. 1.https://github.com/gfleury/eap8021x-debug https://opensource.apple.com/source/eap8021x/eap8021x-304.100.1/ Our enterprise network authentication is PEAP. So far, I have created a profile using the following commands and have done the access. ./eapolcfg createProfile --authType PEAP --SSID myssid --securityType WPA2 --userDefinedName MyProfile ./eapolcfg setPasswordItem --password mypassword --name myname --SSID myssid ./eapolcfg startAuthentication --interface en0 --SSID myssid After I performed this series of operations, I passed BOOL success = [self.interface associateToEnterpriseNetwork:network identity:nil username:username password:password error:&amp;error]; Connection will pop up the following pop-up window, sometimes associateToEnterpriseNetwork will fail. I don't know what went wrong, is it that I missed some steps through the eapolcfg [tool?] This function also reports the following error：Error Domain=com.apple.coreWLAN.EAPOL.error Code=1 "(null)" Please answer my questions. Thank you very much
