This is a major issue. After my iPhone 12 Pro was upgraded to iOS 26 beta 6, Apple's official Wi-Fi Aware Sample APP crashed immediately and couldn't be opened. It just force closes. Has any developer encountered this problem?

iPhone 12 pro with iOS 26.0 (23A5276f) App: https://developer.apple.com/documentation/wifiaware/building-peer-to-peer-apps We aim to use Wi-Fi Aware to establish file transfer between Android and Apple devices. Apple will act as the Publisher, and Android will act as the Subscriber. According to the pairing process outlined in the Wi-Fi Aware protocol (Figure 49 in the Wi-Fi Aware 4.0 specification), the three PASN Authentication frames have been successfully exchanged. Subsequently, Android sends the encrypted Follow-up PMF to Apple, but the Apple log shows: Failed to parse event. Please refer to the attached complete log. We request Apple to provide a solution. apple Log-20250808a.txt

we use the api as NEHotspotConfigurationManager.shared.apply(hotspotConfig) to join a wifi, but we find that in in iphone 17+, some user report the time to join wifi is very slow the full code as let hotspotConfig = NEHotspotConfiguration(ssid: sSSID, passphrase: sPassword, isWEP: false) hotspotConfig.joinOnce = bJoinOnce if #available(iOS 13.0, *) { hotspotConfig.hidden = true } NEHotspotConfigurationManager.shared.apply(hotspotConfig) { [weak self] (error) in guard let self else { return } if let error = error { log.i("connectSSID Error while configuring WiFi: \(error.localizedDescription)") if error.localizedDescription.contains("already associated") { log.i("connectSSID Already connected to this WiFi.") result(["status": 0]) } else { result(["status": 0]) } } else { log.i("connectSSID Successfully connected to WiFi network \(sSSID)") result(["status": 1]) } } Normally it might only take 5-10 seconds, but on the iPhone 17+ it might take 20-30 seconds.

Hi! My project has the Local Push Connectivity entitlement for a feature we have requiring us to send low-latency critical notifications over a local, private Wi-Fi network. We have our NEAppPushProvider creating a SSE connection using the Network framework with our hardware running a server. The server sends a keep-alive message every second. On an iPhone 16 with iOS 18+, the connection is reliable and remains stable for hours, regardless of whether the iOS app is in the foreground, background, or killed. One of our QA engineers has been testing on an iPhone 13 running iOS 16, and has notice shortly after locking the phone, specifically when not connected to power the device seems to turn off the Wi-Fi radio. So when the server sends a notification, it is not received. About 30s later, it seems to be back on. This happens on regular intervals. When looking at our log data, the provider does seem to be getting stopped, then restarted shortly after. The reason code is NEProviderStopReasonNoNetworkAvailable, which further validates that the network is getting dropped by the device in regular intervals. My questions are: Were there possibly silent changes to the framework between iOS versions that could be the reason we're seeing inconsistent behavior? Is there a connection type we could use, instead of SSE, that would prevent the device from disconnecting and reconnecting to the Wi-Fi network? Is there an alternative approach to allow us to maintain a persistent network connection with the extension or app?

Hello, I am currently developing a headless macOS daemon (HarmonBridge) that requires extremely low-latency, high-bandwidth UDP video streaming between a Mac and a Linux host over a dedicated 2.5GbE/5GbE local network link. We are utilizing widely available Realtek RTL8156 / RTL8156B based USB 2.5G network adapters. Under macOS, these adapters default to the generic com.apple.DriverKit.AppleUserECM driver. The hardware itself natively supports Jumbo Frames (MTU 9000), but the DriverKit implementation artificially restricts the MTU cap to 1500 bytes. Because we are forced through MTU 1500, we are incurring significant performance penalties: Excessive IP fragmentation for our large UDP video payloads. Unnecessary CPU overhead due to increased hardware interrupts and header processing at 2.5Gbps speeds. For a latency-critical application like ours, reducing CPU interrupts and utilizing true hardware-level Jumbo Frames is essential. My Questions: Is there an undocumented boot-arg or network sysctl parameter that permits overriding the AppleUserECM 1500 MTU hard-limit for 2.5G USB adapters on Apple Silicon? Are there any roadmap plans from the DriverKit/Networking team to re-enable standard Jumbo Frame negotiation for RTL8156 hardware using the generic ECM driver? If the answer to both is no, does Apple grant NetworkingDriverKit Entitlements to independent developers specifically for the purpose of writing custom hardware overrides to patch missing MTU features in the default ECM stack? Because AppleUserECM effectively acts as a gatekeeper to the underlying MAC/PHY capabilities of these modern USB NICs, any guidance on achieving wire-native MTU 9000 under the current DriverKit paradigm would be hugely appreciated. Thank you!

We’ve noticed an issue where after running a network extension, if the phone’s language is changed the Locale.preferredLanguages array is not updated and still returns the old array. It only returns the updated array when the app is reinstalled or the phone is restarted. This is unlike the app itself where using the same Locale.preferredLanguages API immediately returns the updated array. We think this issue is also the cause of notifications that are sent by the network extension being in the previous language as long as the app isn’t reinstalled or the phone is restarted, despite our Localizable file having localised strings for the new language. Feedback ID: FB20086051 The feedback report includes a sample project with steps on how to reproduce the issue.

We have an application which is written in Swift, which activates Transparent Proxy network 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 are using JAMF MDM profile for installing our transparent proxy in customer environment. We are using VPN payload(https://developer.apple.com/documentation/devicemanagement/vpn) for this network system extension. This payload does not have any field for order. As per https://developer.apple.com/documentation/devicemanagement/vpn/transparentproxy-data.dictionary documentation there is another payload for TransparentProxy and we could create a Transparent Proxy profile using iMazingProfile Editor. Noticed that, if we add the Order attribute to the VPN/TransparentProxy payload, while installing the extension, the save to preferences fails with "Error in saving TP configuration in updateOnDemandRule permission denied" error. Can we use this Order field to ordering the installed Transparent Proxy extension in a machine? Customer devices will likely have other Transparent Proxy network extensions as well. We want to allow the Customer to control the order in which each Transparent Proxy network extension receives the network traffic. How can we set the order of the Transparent proxy extension that can be deployed using MDM profile with VPN/TransparentProxy payload? Attached the TransparentProxy payload profile for the reference.

Hello, We are facing what we believe is a compatibility issue with two networking APIs. If the Network extension VPN configuration has includeAllNetworks flag enabled and the NEHotspotHelper is registered. The user has internet connection but it is blocked, and there user will get internet back only after restarting the device. VPN Configuration is as below while connecting to VPN, { localizedDescription = WLVPN WireGuard Configuration enabled = YES protocolConfiguration = { serverAddress = <18-char-str> passwordReference = {length = 20, bytes = 0x67656e70ed0d05c06b1b4896bf4fef2031e1a92d} disconnectOnSleep = NO includeAllNetworks = YES excludeLocalNetworks = YES excludeCellularServices = YES excludeAPNs = YES excludeDeviceCommunication = YES enforceRoutes = NO providerBundleIdentifier = com.wlvpn.ios.consumervpn.network-extension } onDemandEnabled = NO onDemandRules = () } After running the code shown below. Regardless if the VPN is connected or not, the user needs to restart his device to regain internet access. private let neHelperQueue = DispatchQueue(label: "com.wlvpn.ios.consumervpn.hotspot", attributes: DispatchQueue.Attributes.concurrent) let options: [String: NSObject] = [kNEHotspotHelperOptionDisplayName : "" as NSObject] let status = NEHotspotHelper.register(options: nil, queue: neHelperQueue) { cmd in NSLog("Received command: \(cmd.commandType.rawValue)") } We need to use the includeAllNetworks flag to prevent the novel "Tunnel vision" vulnerability. Can we please have some help getting confirmation if both functionalities are compatible or if there's a way to enable them at the same time?

how can I prevent handshake when certificate is user installed for example if user is using Proxyman or Charles proxy and they install their own certificates now system is trusting those certificates I wanna prevent that, and exclude those certificates that are installed by user, and accept the handshake if CA certificate is in a real valid certificate defined in OS I know this can be done in android by setting something like <network-security-config> <base-config> <trust-anchors> <certificates src="system" /> </trust-anchors> </base-config> </network-security-config>

For a past few days, I have been exploring control Filter and data filter. I am unable to understand how control moves from various functions of data filter to control Filter. One thing that I am unable to figure out is that when I pass verdict as .allow in dataFilter's handleNewFlow and mark .shouldReport as true, I get inBytes and outbytes in the flow report of handle() in controlFilter. But when I pass verdict as needRules and wait till the handle is called in controlFilter when the report.event == .flowClosed, I don't get inBytes and outBytes. I am unable to understand this complete flow of network extension from the apple documentation. Can someone provide me with some flow chart or some pictorial representation or detailed explanation of network extension for iOS? Also is there some way to imitate the ..statisticsReportFrequency for iOS as it is not available for iOS?

On macOS Tahoe26.0, iOS 26.0 (23A5287g), Xcode 26.0 beta 3 (17A5276g) 1、Follow this tutorial Downloading asset packs hosted by Apple When i download a background asset packs hosted by Apple, Xcode callback "Download failed: The helper received an invalid server response with the status code “400”." Before downloading, I uploaded the three aar files to the Apple server using the Transporter app. Three Manifest.json content is： {"assetPackID":"bdassets2","downloadPolicy":{"onDemand":{}},"fileSelectors":[{"file":"1.jpg"},{"file":"2.pag"},{"file":"3.mp4"}],"platforms":["iOS"]} and {"assetPackID":"bdassets1","downloadPolicy":{"prefetch":{"installationEventTypes":["firstInstallation","subsequentUpdate"]}},"fileSelectors":[{"file":"1.jpg"},{"file":"2.pag"},{"file":"3.mp4"},{"directory":"a1"}],"platforms":["iOS"]} and {"assetPackID":"bdassets0","downloadPolicy":{"essential":{"installationEventTypes":["firstInstallation","subsequentUpdate"]}},"fileSelectors":[{"file":"1.jpg"},{"file":"2.pag"},{"file":"3.mp4"},{"directory":"a1"}],"platforms":["iOS"]} The same error was reported when the three aar files were obtained. I obtained it using the following code: do {       let assetPack = try await AssetPackManager.shared.assetPack(withID: "bdassets2")       try await AssetPackManager.shared.ensureLocalAvailability(of: assetPack)     } catch {       print("Download failed:", error)     } 2、Follow this tutorial Testing your asset packs locally I use this command line to start the test server：xcrun ba-serve --host 172.17.9.62 bdassets2.aar, The content displayed on the terminal is： Loading asset packs… Loading the asset pack at “bdassets2.aar”… Choose an identity in the panel to continue. Listening on port 56061… When running the project, Xcode reports an error:Download failed: Could not connect to the server. I use iPhone directly visit this website: https://172.17.9.62:56061, on the page display "Hello, world!" There are too few error messages in both of the above questions. I have no idea what the specific reasons are.I hope someone can offer some guidance. Best Regards.

I'm currently testing URLFilter for use in a macOS product. After calling loadFromPreferences, I set the following configuration parameters: pirServerURL = URL(string: "http://localhost:8080")! pirAuthenticationToken = "AAAA" controlProviderBundleIdentifier = "{extension app bundle identifier}" However, when I call saveToPreferences, I get an Invalid Configuration error. Is there a way to determine which parameter is invalid or incorrectly set? Also, I would appreciate any macOS-specific examples of using NEURLFilterManager, as most of the documentation I’ve found seems to focus on iOS. Thank you.

send a request and it returns with timeout Integration Team are Using Fortigate as a firewall and NGINX for some reasons so we use VPN TO Access , requests always succeed but at once it failed with timeout in randomize request not specific one we are using URLSession as a network layer when I retry the same failed request again, it success the request cannot connect apigee Sec Team concern { app session hits the security gateway with lots of SYN step to try to initiate a new session and doesn’t wait for (SYN-ACK / ACK) steps to happen to make sure the connection initiated correctly and gateway consider it flooding attack }

I haven’t come across any official documentation regarding the limit on the number of Network Extensions macOS can run. However, I did see some discussions suggesting that Apple might restrict this to 5 extensions in macOS Tahoe. Is there any official confirmation on this?

Hi,I am trying to create an NAT64 Network with Sharing options to test my Apps.I did follow the guide provided here https://forums.developer.apple.com/thread/14213But even with the option key pressed the "Create NAT64 Network" check box is still missing.I am using a OS X 10.11Any ideas?!

Goal : Block all outbound connections to a static list of hosts (both In-app requests and WKWebView/Safari). App & both extensions have Network Extension entitlement with content-filter-provider and filter-control-provider What’s working: Safari and WKWebView requests matching the block list are dropped. What’s broken: In-app traffic never reaches the Data Provider—those requests always succeed. Setup: • NEFilterProviderConfiguration with both Data & Control providers, filterBrowsers = true, filterSockets = true • Data Provider implements handleNewFlow for socket/browser flows • Control Provider implements handleNewFlow for browser flows • Enabled via saveToPreferences() and toggled ON in Settings

Hello, I encountered a memory management issue while developing VPN functionality and would like to seek your advice. The specific phenomenon is as follows: Problem description: After multiple calls to the 'createTCPConnectToEndpoint' and 'create UDPSessionToEndpoint' interfaces to create connection objects, the application memory continues to grow. Even if the cancel interface is immediately called to actively release the object, the memory does not fall back. 3. Confirm that there is no other code referencing these objects, but the system does not seem to automatically reclaim memory. Attempted measures: Immediately call the cancel method after creating the object, and the memory is not reduced Use tools such as Profiler to monitor memory and confirm that objects have not been released. doubt: Is this phenomenon normal? Is there a known memory management mechanism (such as cache pooling) that causes delayed release? 2. Are there any other interfaces or methods (such as release, dispose) that need to be explicitly called? Supplementary Information: Development environment: [iOS 16, 14pm] Reproduction steps: After continuously creating connection objects, the memory grows without falling back. Could you please help confirm if there are any abnormalities and the correct memory release posture. Thank you for your support!

I am seeking assistance with how to properly handle / save / reuse NWConnections when it comes to the NWBrowser vs NWListener. Let me give some context surrounding why I am trying to do what I am. I am building an iOS app that has peer to peer functionality. The design is for a user (for our example the user is Bob) to have N number of devices that have my app installed on it. All these devices are near each other or on the same wifi network. As such I want all the devices to be able to discover each other and automatically connect to each other. For example if Bob had three devices (A, B, C) then A discovers B and C and has a connection to each, B discovers B and C and has a connection to each and finally C discovers A and B and has a connection to each. In the app there is a concept of a leader and a follower. A leader device issues commands to the follower devices. A follower device just waits for commands. For our example device A is the leader and devices B and C are followers. Any follower device can opt to become a leader. So if Bob taps the “become leader” button on device B - device B sends out a message to all the devices it’s connected to telling them it is becoming the new leader. Device B doesn’t need to do anything but device A needs to set itself as a follower. This detail is to show my need to have everyone connected to everyone. Please note that I am using .includePeerToPeer = true in my NWParameters. I am using http/3 and QUIC. I am using P12 identity for TLS1.3. I am successfully able to verify certs in sec_protocal_options_set_verify_block. I am able to establish connections - both from the NWBrowser and from NWListener. My issue is that it’s flaky. I found that I have to put a 3 second delay prior to establishing a connection to a peer found by the NWBrowser. I also opted to not save the incoming connection from NWListener. I only save the connection I created from the peer I found in NWBrowser. For this example there is Device X and Device Y. Device X discovers device Y and connects to it and saves the connection. Device Y discovers device X and connects to it and saves the connection. When things work they work great - I am able to send messages back and forth. Device X uses the saved connection to send a message to device Y and device Y uses the saved connection to send a message to device X. Now here come the questions. Do I save the connection I create from the peer I discovered from the NWBrowser? Do I save the connection I get from my NWListener via newConnectionHandler? And when I save a connection (be it from NWBrowser or NWListener) am I able to reuse it to send data over (ie “i am the new leader command”)? When my NWBrowser discovers a peer, should I be able to build a connection and connect to it immediately? I know if I save the connection I create from the peer I discover I am able to send messages with it. I know if I save the connection from NWListener - I am NOT able to send messages with it — but should I be able to? I have a deterministic algorithm for who makes a connection to who. Each device has an ID - it is a UUID I generate when the app loads - I store it in UserDefaults and the next time I try and fetch it so I’m not generating new UUIDs all the time. I set this deviceID as the name of the NWListener.Service I create. As a result the peer a NWBrowser discovers has the deviceID set as its name. Due to this the NWBrowser is able to determine if it should try and connect to the peer or if it should not because the discovered peer is going to try and connect to it. So the algorithm above would be great if I could save and use the connection from NWListener to send messages over.

Greetings I'm trying to get on iPad the SSID from the wifi I'm connected to. For that, I added the wifi entitlement and I'm requesting permission to the user for Location. Once I have it, I'm using the function CNCopySupportedInterfaces to get the interfaces, but I can only receive the en0, which using the method CNCopyCurrentNetworkInfo returns nil. I also tried using the NEHotspotNetwork.fetchCurrent and the SSID keeps being nil. So right now I'm drawing a blank. Is there any way to make it work? Thanks.
