I am developing an iOS application based on Objective-C, and I have encountered a requirement where I need to determine if the password for the currently connected Wi-Fi is empty. If it is empty, the user is allowed to proceed to the next step. If it is not empty, they must enter a password. This will be used in the next process, which is the network configuration of a physical device. After researching documentation, I found two possible approaches to determine if the Wi-Fi password is empty. The first approach is to directly check the encryption type of the current Wi-Fi. If there is no encryption type, the Wi-Fi password is empty. The second approach is to use Apple's NEHotspotConfiguration class to attempt connecting to the Wi-Fi and determine if the password is empty. However, both approaches have encountered issues. For the first approach, there seems to be no public API available to directly retrieve the Wi-Fi encryption type. For the second approach, when using NEHotspotConfiguration to connect, I first get the Wi-Fi's SSID and then attempt to connect with an empty password. I am using [NEHotspotConfiguration alloc] initWithSSID:ssid] to create a configuration, and then I call [NEHotspotConfigurationManager sharedManager] applyConfiguration: to connect. However, regardless of whether the Wi-Fi is actually encrypted or unencrypted, no error is returned. The code is as follows: NSString *ssid = [NetInterface getCurrent_SSID]; // The Wi-Fi SSID that needs to be checked NEHotspotConfiguration *configuration = [[NEHotspotConfiguration alloc] initWithSSID:ssid]; configuration.joinOnce = YES; // Remove previous configuration (optional) [[NEHotspotConfigurationManager sharedManager] removeConfigurationForSSID:ssid]; self.isWiFiEmptyOperateState = 1; // Attempt to apply the new configuration [[NEHotspotConfigurationManager sharedManager] applyConfiguration:configuration completionHandler:^(NSError * _Nullable error) { self.isWiFiEmptyOperateState = 2; if (error) { if (error.code == NEHotspotConfigurationErrorInvalid) { NSLog(@"Wi-Fi %@ is encrypted, a password is required", ssid); } else if (error.code == NEHotspotConfigurationErrorUserDenied) { NSLog(@"User denied the Wi-Fi configuration"); } else { NSLog(@"Other error: %@", error.localizedDescription); } } else { NSLog(@"Successfully connected to Wi-Fi %@, this network might be open", ssid); } }]; In the code above, it always ends up logging "Successfully connected to Wi-Fi." Is there any other approach that can fulfill my functional requirement? I noticed that some apps on the App Store have implemented this functionality, but all my attempts so far have failed.

Hi everyone, I developed an Android version of a VPN app built with Flutter using OpenVPN, and it works perfectly on Android. However, when porting it to iOS, I’ve encountered an issue: the app connects successfully but then automatically disconnects when tested via TestFlight. We’ve already added all the necessary network extensions. Despite this, we decided to submit the app to the App Store. It’s been five days now, and the app is still 'Waiting for Review.' Could anyone share their experience deploying and working on an iOS version of a VPN app? I’d really appreciate your insights!

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: 2025-02-04 14:16:31.219192+0100 0xc01342 Default 0x0 86459 0 wifianalyticsd: [com.apple.wifi.analytics:Default] -[DPSQuickRecoveryRecommendationEngine updateTimeSincePreviousTriggerForStudy:msgKey:dictKey:]::913:msgkey:WFAAWDWASDS_symptomsDnsTimeSincePreviousTriggerMinutes dictKey:dps_lastSymptomsDpsTrigger previous_TS:(null) current_TS:Tue Feb 4 14:16:31 2025 difference:0 2025-02-04 14:16:31.219704+0100 0xc01342 Default 0x0 86459 0 wifianalyticsd: [com.apple.wifi.analytics:Default] -[DPSQuickRecoveryRecommendationEngine updateScreenState]::198:DPS Fast Reset Recommendation Engine: (screenON & foreGrnd traffic) is DETECTED 2025-02-04 14:16:31.219713+0100 0xc01342 Default 0x0 86459 0 wifianalyticsd: [com.apple.wifi.analytics:Default] -[DPSQuickRecoveryRecommendationEngine recommendSymptomsDpsRecovery:symptomsDnsStats:awdlState:currentSymptomsCondition:isLANPingSuccessful:appUsage:averageCCA:]::966:PeerDiagnostics: Data not received from peerDiagnostics 2025-02-04 14:16:31.219714+0100 0xc01342 Default 0x0 86459 0 wifianalyticsd: [com.apple.wifi.analytics:Default] -[DPSQuickRecoveryRecommendationEngine checkForPriorityNetwork]::256:Priority Network Check Disabled: NO IsPriorityNetwork: YES 2025-02-04 14:16:31.219732+0100 0xc01342 Default 0x0 86459 0 wifianalyticsd: [com.apple.wifi.analytics:Default] -[DPSQuickRecoveryRecommendationEngine isResetAllowedForKey:forPrefSelector:]::330:key:symptomsDps_lastScreenOnRecoveryWD previousWD_TS:(null) currentWD_TS:Tue Feb 4 14:16:31 2025 recommendation:YES 2025-02-04 14:16:31.219735+0100 0xc01342 Default 0x0 86459 0 wifianalyticsd: [com.apple.wifi.analytics:Default] -[DPSQuickRecoveryRecommendationEngine updateSymptomsDPSRecoveryWDStatsForKey:]::210:Added key: symptomsDps_numRecommendedScreenOnRecoveryWD value:1 dict:(null) 2025-02-04 14:16:31.219737+0100 0xc01342 Default 0x0 86459 0 wifianalyticsd: [com.apple.wifi.analytics:Default] -[DPSQuickRecoveryRecommendationEngine recommendSymptomsDpsRecovery:symptomsDnsStats:awdlState:currentSymptomsCondition:isLANPingSuccessful:appUsage:averageCCA:]::1023:PeerDiagnostics: Recommendation for DNS Symptoms Recovery: Reassoc Do you guys have any idea where can I see that DNS symptoms?

Hello there, I'm trying to consume graph.microsoft.com API by using URLSession. But I'm getting Error 400 from the server every time when I send a request with URLSession, but not if I use Postman for the same request. And when I examined the requests with Fiddler, I noticed that URLSession use HTTP/2, and Postman use HTTP/1.1. According to the Microsoft's documentation graph.microsoft.com supports only HTTP/1.1. As I understand URLSession decides to which version of HTTP to use during ALPN and will use HTTP/2 only if the server support it. My question is it possible the graph server to advertise itself as its support HTTP/2 and how to determinate this? Or maybe, which is more likely URLSession has bug that make it to do the wrong assumption about the HTTP/2. And most important there is there a mechanism to make URLSession to use a certain version of HTTP? Thank you in advance, Emil

Hi I just encountered an reachability detection problem by calling SCNetworkReachabilityGetFlags function in iOS 16. what did I do: on device iPhone 12, iOS 16.1.1, turn on Airplane Mode, call SCNetworkReachabilityGetFlags, got flags = kSCNetworkReachabilityFlagsTransientConnection | kSCNetworkReachabilityFlagsReachable on device iPhone 7, iOS 14.5.1, turn on Airplane Mode, call SCNetworkReachabilityGetFlags, got flags = 0 what I expect: I'm expecting SCNetworkReachabilityGetFlags on my iOS 16.1 device behave same as my iOS 14.5 device, returning flags = 0. It's inappropriate returning kSCNetworkReachabilityFlagsReachable in this case. Thank you!

System extensions on iOS have very low limits on allowed memory. For instance the DNS proxy extensions seem to be limited to 15MB. When I try to monitor the extension with instruments it quickly runs out of memory, most likely due to the way instruments tracks memory usage. I did find that there are two entitlements related to memory usage but it is unclear if these would work for extensions or only for applications. What are the best techniques for debugging extensions that run out of memory? Is there a way to temporarily increase the limit while debugging?

Could anyone tell me how to detect status of Local Network for iOS 18+ systems ?

I am currently developing a custom-protocol VPN application for iOS using PacketTunnelProvider. I have also integrated an HTTP proxy service, which is launched via a dylib. The overall flow is as follows: App -> VPN TUN -> Local HTTP Proxy -> External Network I have a question: I am capturing all traffic, and normally, requests sent out by the HTTP proxy are also captured again by the VPN. However, when I send requests using createUdpSession in my code, they are not being captured by the virtual interface (TUN). What could be the reason for this? override func startTunnel(options: [String : NSObject]?, completionHandler: @escaping (Error?) -> Void) { let tunnelNetworkSettings = NEPacketTunnelNetworkSettings(tunnelRemoteAddress: "192.168.18.0") tunnelNetworkSettings.mtu=1400 let ipv4Settings = NEIPv4Settings(addresses: ["192.169.10.10"], subnetMasks: ["255.255.255.0"]) ipv4Settings.includedRoutes=[NEIPv4Route.default()] ipv4Settings.excludedRoutes = [NEIPv4Route(destinationAddress: "10.0.0.0", subnetMask: "255.0.0.0"), NEIPv4Route(destinationAddress: "172.16.0.0", subnetMask: "255.240.0.0"), NEIPv4Route(destinationAddress: "192.168.0.0", subnetMask: "255.255.0.0"), NEIPv4Route(destinationAddress:"127.0.0.0", subnetMask: "255.0.0.0"), ] tunnelNetworkSettings.ipv4Settings = ipv4Settings // Configure proxy settings let proxySettings = NEProxySettings() proxySettings.httpEnabled = true proxySettings.httpServer = NEProxyServer(address: "127.0.0.1", port: 7890) proxySettings.httpsEnabled = true proxySettings.httpsServer = NEProxyServer(address: "127.0.0.1", port: 7890) proxySettings.excludeSimpleHostnames = true proxySettings.exceptionList=["localhost","127.0.0.1"] tunnelNetworkSettings.proxySettings = proxySettings setTunnelNetworkSettings(tunnelNetworkSettings) { [weak self] error in if error != nil { completionHandler(error) return } completionHandler(nil) let stack = TUNInterface(packetFlow: self!.packetFlow) RawScoketFactory.TunnelProvider=self stack.register(stack: UDPDirectStack()) stack.register(stack: TCPDirectStack()) stack.start() } } NWUdpSession.swift // // NWUDPSocket.swift // supervpn // // Created by TobbyQuinn on 2025/2/3. // import Foundation import NetworkExtension import CocoaLumberjack public protocol NWUDPSocketDelegate: AnyObject{ func didReceive(data:Data,from:NWUDPSocket) func didCancel(socket:NWUDPSocket) } public class NWUDPSocket:NSObject{ private let session:NWUDPSession private let timeout:Int private var pendingWriteData: [Data] = [] private var writing = false private let queue:DispatchQueue=QueueFactory.getQueue() public weak var delegate:NWUDPSocketDelegate? public init?(host:String,port:UInt16,timeout:Int=Opt.UDPSocketActiveTimeout){ guard let udpSession = RawScoketFactory.TunnelProvider?.createUDPSession(to: NWHostEndpoint(hostname: host, port: "\(port)"), from: nil) else{ return nil } session = udpSession self.timeout=timeout super.init() session.addObserver(self, forKeyPath: #keyPath(NWUDPSession.state),options: [.new], context: nil) session.setReadHandler({ dataArray, error in self.queueCall{ guard error == nil, let dataArray = dataArray else { print("Error when reading from remote server or connection reset") return } for data in dataArray{ self.delegate?.didReceive(data: data, from: self) } } }, maxDatagrams: 32) } /** Send data to remote. - parameter data: The data to send. */ public func write(data: Data) { pendingWriteData.append(data) checkWrite() } public func disconnect() { session.cancel() } public override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) { guard keyPath == "state" else { return } switch session.state { case .cancelled: queueCall { self.delegate?.didCancel(socket: self) } case .ready: checkWrite() default: break } } private func checkWrite() { guard session.state == .ready else { return } guard !writing else { return } guard pendingWriteData.count > 0 else { return } writing = true session.writeMultipleDatagrams(self.pendingWriteData) {_ in self.queueCall { self.writing = false self.checkWrite() } } self.pendingWriteData.removeAll(keepingCapacity: true) } private func queueCall(block:@escaping ()->Void){ queue.async { block() } } deinit{ session.removeObserver(self, forKeyPath: #keyPath(NWUDPSession.state)) } }

What I want to do? I want to completely block network traffic for installed iOS apps. Hence, I need to filter network traffic based on the app, which executes this network request. Note that my app is created for personal use and learning purposes. How is this possible on iOS. Could you kindly point me into the right direction? What I don't want to do? Block network requests just by using the given domain names or using local VPNs. What I did? I skimmed through the Network Extension documentation and this forum. https://developer.apple.com/documentation/networkextension/content-filter-providers?language=objc https://developer.apple.com/forums/thread/692597 Thank you!

How to solve this problem

Dear Apple Support Team, I hope this message finds you well. I am writing to seek clarification on a specific aspect of Wi-Fi connectivity related to the iPhone 16 series running iOS 18.0. We have encountered an issue where the iPhone 16 series devices fail to connect to Wi-Fi networks, and this failure subsequently affects other devices running iOS 18.0. To better understand the root cause of this issue, I would like to inquire about the differences in the "authentication and encryption" processes between the iPhone 16 series running iOS 18.0 and other devices running iOS 18.0. Specifically, are there any changes or updates in the Wi-Fi authentication and encryption mechanisms that are unique to the iPhone 16 series? Understanding these differences will greatly assist us in diagnosing and resolving the connectivity issues we are experiencing. Thank you for your assistance. I look forward to your prompt response. Best regards, WJohn

NEFilterManager.shared().loadFromPreferences { loadError in DispatchQueue.global.async { ... } } the code above is executed in an app-like deamon and completionHandler was never invoked, same code in an application works fine.(they are both packed with content filter network system extension) is it because of the restriction of app-like deamon?

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 my /etc/pf.conf # scrub-anchor "com.apple/*" nat-anchor "com.apple/*" rdr-anchor "com.apple/*" rdr pass on bridge100 inet proto tcp from 192.168.2.104 to any port {80, 443, 8883} -> 127.0.0.1 port 8080 dummynet-anchor "com.apple/*" anchor "com.apple/*" load anchor "com.apple" from "/etc/pf.anchors/com.apple"

My code makes an iPhone use the CBCentralManager to talk to devices peripherals over core bluetooth. After attempting a connect to a peripheral device, I get a didConnect callback on CBCentralManagerDelegate. After this I initiate discovery of services using: peripheral.discoverServices([CBUUID(nsuuid: serviceUUID)]) Since I am only interested in discovering my service of interest and not the others to speed up time to the actual sending of data. This also gives me the didDiscoverServices callback without error prints in which I do the following: guard let services = peripheral.services, !services.isEmpty else { print("Empty services") centralManager.cancelPeripheralConnection(peripheral) return } And for next steps if let serviceOfInterest = services.first(where: {$0.uuid == CBUUID(nsuuid: serviceUUID)}) { //double check for service we want initiateDiscoverCharacteristics(peripheral: peripheral, service: serviceOfInterest) } Below is what initiateDiscoverCharacteristics() does. I basically only tries to discover certain characteristics of the selected service: peripheral.discoverCharacteristics( [CBUUID(nsuuid: readUUID), CBUUID(nsuuid: writeUUID)], for: serviceOfInterest) For this also we get the didDiscoverCharacteristicsFor callback without error prints. Here in this callback however we were not doing the serviceOfInterest check to see that we are getting the callback for the service we expect, since our understanding was that we will get didDiscoverCharacteristicsFor callback for the characteristics on the serviceOfInterest because that is what peripheral.discoverCharacteristics() was initiated for. When we go ahead to write some data/subscribe for notify/read data we have 2 guard statements for services and characteristics of a particular service. The first guard below passes: if(peripheral.services == nil) { print("services yet to be discovered \(peripheral.identifier.uuidString)") return } However the second guard below fails: let serviceOfInterest = peripheral.services?.first(where: {$0.uuid == CBUUID(nsuuid: serviceUUID}) if((serviceOfInterest?.characteristics == nil) || (serviceOfInterest?.characteristics == [])) { print("characteristics yet to be discovered \(peripheral.identifier.uuidString)") return } First of all, does the iPhone go ahead and discover other characteristics and services separately even when we explicitly mention the service and the characteristics it should discover? Now if you say yes and that it maybe the reason of our bug because we didn't do a check for serviceOfInterest in didDiscoverCharacteristicsFor callback, then I have another question. Why don't we get a second/third print in didDiscoverCharacteristicsFor callback signifying that more characteristics were discovered? The peripheral device just disconnects after a set timeout (peripheral device used in our testing does this if we are not communicating with it for a certain amount of time). This issue is extremely rare. We have seen it only twice in our customer base. Both the instances were on the same iPhone 15 Pro. Once a few months back and once recently. Currently, this iPhone is having iOS version 18.1.1 running on it.

Hi all, I'm struggling to identify the cause of a really strange issue that has started to plague our network of Mac devices. We use Cisco switches and have port security turned on which means any device that registers more than one MAC address triggers a port violation which then shuts down the port for a short period of time (5 mins I believe). A few months ago we suddenly started get lots of violations from Mac devices the were all registering additional MAC addresses (2 usually) that all had the same 6 character prefix (00:00:40). So far we've not been able to determine the cause and now getting pretty desperate and exploring all possible avenues. All we know id that prefix is registered to a company called Applicon from back in the day but is now shut down. Has anyone come across this issue or know of any possible reason why this may be happening? Thanks

Hi Team, Looking for an answer, if it's just us or a widespread issue. Since Sept, our clients Apple devices can't load a Captive Portal on Apple devices. Client wants the CNA to pop up and I can't get it to happen! Android and Windows devices all work correctly with their respective popups, but CNA will not work. No changes done on our side and after multiple tshoots and getting vendors to take multiple PCAPs found, Apple devices are not initiating a HTTP GET request as per Meraki >> https://documentation.meraki.com/MR/MR_Splash_Page/Splash_Page_Traffic_Flow_and_Troubleshooting The work around is to force a HTTP GET request by manually going into the browser and initiate a http site (we tried 1.1.1.1, also tried other public HTTP sites and it works) and that redirects to our Captive Portal page.
