We need your assistance as we are currently facing an issue without a workaround for users on macOS 15.4 and 15.5. FeedbackID: FB17547675 The problem has been observed on macOS versions 15.4 and 15.5. Apple has acknowledged this issue and confirmed that it is fixed in the macOS 15.6 beta. Although we tried to reproduce the issue in our environment, it did not occur, even on macOS 15.5. Therefore, we cannot verify if the fix in macOS 15.6 beta resolves the problem. We are actively working to identify an appropriate workaround for users on macOS 15.5. Some users have reported a failure to obtain an IP address over Wi-Fi, possibly due to a DHCP failure. As a temporary solution, we added logic to restart Wi-Fi programmatically when either an APIPA address (169.254.x.x) or no IPv4 address is detected on the active interface. However, restarting Wi-Fi does not always resolve the issue, and the device may still fail to obtain an IP address over Wi-Fi or Ethernet. Could you advise if there is a reliable method to detect DHCP failure and recover the device from this state? Also, any idea, how we can reproduce this scenario in our machine? Below is the failure. default 2025-06-27 10:07:57.055003 -0700 configd DHCP en0: ARP router: No leases to query for default 2025-06-27 10:07:57.055269 -0700 configd DHCP en0: status = 'no server' default 2025-06-27 10:08:23.336215 -0700 airportd WiFiUsageBssSession:: ChannelAfterRoam=0; ChannelAtJoin=36; FaultReasonApsdTimedOut=0; FaultReasonArpFailureCount=0; FaultReasonBrokenBackhaulLinkFailed=0; FaultReasonDhcpFailure=0; default 2025-06-27 10:08:23.367852 -0700 configd DHCP en0: status = 'media inactive' default 2025-06-27 10:08:23.367909 -0700 configd DHCP en0: INACTIVE default 2025-06-27 10:08:23.988565 -0700 configd DHCP en0: status = 'media inactive' default 2025-06-27 10:08:23.988703 -0700 configd DHCP en0: INACTIVE info 2025-06-27 10:08:23.988852 -0700 configd DHCPv6 en0: Inactive default 2025-06-27 10:08:35.656415 -0700 configd DHCP en0: status = 'network changed' default 2025-06-27 10:08:35.656817 -0700 configd DHCP en0: INIT default 2025-06-27 10:08:35.656821 -0700 configd DHCP en0: supplying device type 'Mac' info 2025-06-27 10:08:35.656934 -0700 configd DHCP en0: busy default 2025-06-27 10:08:35.657351 -0700 configd DHCP en0: INIT waiting at 0 for 1.358613 info 2025-06-27 10:08:35.657404 -0700 configd DHCPv6 en0: Inactive default 2025-06-27 10:08:37.019229 -0700 configd DHCP en0: INIT waiting at 1.36206 for 2.113913 default 2025-06-27 10:08:39.136955 -0700 configd DHCP en0: INIT waiting at 3.47937 for 4.462224 default 2025-06-27 10:08:43.602229 -0700 configd DHCP en0: ARP router: No leases to query for default 2025-06-27 10:08:43.603143 -0700 configd DHCP en0: INIT waiting at 7.94533 for 8.128784 default 2025-06-27 10:08:51.735532 -0700 configd DHCP en0: ARP router: No leases to query for default 2025-06-27 10:08:51.735846 -0700 configd DHCP en0: INIT waiting at 16.0786 for 8.749985 default 2025-06-27 10:09:00.488315 -0700 configd DHCP en0: ARP router: No leases to query for default 2025-06-27 10:09:00.488550 -0700 configd DHCP en0: INIT waiting at 24.8313 for 8.496864 default 2025-06-27 10:09:08.988284 -0700 configd DHCP en0: ARP router: No leases to query for default 2025-06-27 10:09:08.988310 -0700 configd DHCP en0: reported address acquisition failure symptom default 2025-06-27 10:09:08.988579 -0700 configd DHCP en0: INIT waiting at 33.3312 for 8.300735 default 2025-06-27 10:09:17.294478 -0700 configd DHCP en0: ARP router: No leases to query for info 2025-06-27 10:09:17.294485 -0700 configd DHCP en0: symptom failure already reported default 2025-06-27 10:09:17.295454 -0700 configd DHCP en0: INIT waiting at 41.6373 for 8.798768 default 2025-06-27 10:09:26.096673 -0700 configd DHCP en0: ARP router: No leases to query for info 2025-06-27 10:09:26.096688 -0700 configd DHCP en0: symptom failure already reported default 2025-06-27 10:09:26.097553 -0700 configd DHCP en0: INIT waiting at 50.4394 for 8.807943 default 2025-06-27 10:09:34.909050 -0700 configd DHCP en0: ARP router: No leases to query for info 2025-06-27 10:09:34.909054 -0700 configd DHCP en0: symptom failure already reported default 2025-06-27 10:09:34.909375 -0700 configd DHCP en0: INIT waiting at 59.2517 for 8.877971 default 2025-06-27 10:09:43.792458 -0700 configd DHCP en0: ARP router: No leases to query for info 2025-06-27 10:09:43.792464 -0700 configd DHCP en0: symptom failure already reported default 2025-06-27 10:09:43.793641 -0700 configd DHCP en0: status = 'no server' info 2025-06-27 10:09:43.794145 -0700 configd DHCP en0: not busy DNS failure resolver #1 flags : reach : 0x00000000 (Not Reachable) resolver #2 domain : local options : mdns timeout : 5 flags : reach : 0x00000000 (Not Reachable) order : 300000 resolver #3 domain : 254.169.in-addr.arpa options : mdns timeout : 5 flags : reach : 0x00000000 (Not Reachable) order : 300200 resolver #4 domain : 8.e.f.ip6.arpa options : mdns timeout : 5 flags : reach : 0x00000000 (Not Reachable) order : 300400 resolver #5 domain : 9.e.f.ip6.arpa options : mdns timeout : 5 flags : reach : 0x00000000 (Not Reachable) order : 300600 resolver #6 domain : a.e.f.ip6.arpa options : mdns timeout : 5 flags : reach : 0x00000000 (Not Reachable) order : 300800 resolver #7 domain : b.e.f.ip6.arpa options : mdns timeout : 5 flags : reach : 0x00000000 (Not Reachable) order : 301000 Route table Destination Gateway Flags Netif Expire 127 127.0.0.1 UCS lo0 127.0.0.1 127.0.0.1 UH lo0 169.254 link#14 UCS en0 ! 169.254.160.160/32 link#14 UCS en0 ! 224.0.0/4 link#14 UmCS en0 ! 224.0.0.251 1:0:5e:0:0:fb UHmLWI en0 239.255.255.250 1:0:5e:7f:ff:fa UHmLWI en0 255.255.255.255/32 link#14 UCS en0 !

Hello, We have a SwiftUI-based application that runs as a LaunchAgent and communicates with other internal components using Unix domain sockets (UDS). On Sequoia (macOS virtualized environment), when installing the app, we encounter the Local Network Privacy Alert, asking: "Allow [AppName] to find and connect to devices on the local network?" We are not using any actual network communication — only interprocess communication via UDS. Is there a way to prevent this system prompt, either through MDM configuration or by adjusting our socket-related implementation? Here's a brief look at our Swift/NIO usage: class ClientHandler: ChannelInboundHandler { ... public func channelRead(context: ChannelHandlerContext, data: NIOAny) { ... } ... } // init bootstrap. var bootstrap: ClientBootstrap { return ClientBootstrap(group: group) // Also tried to remove the .so_reuseaddr, the prompt was still there. .channelOption(ChannelOptions.socketOption(.so_reuseaddr), value: 1) .channelInitializer { channel in // Add ChannelInboundHandler reader. channel.pipeline.addHandler(ClientHandler()) } } // connect to the UDS. self.bootstrap.connect(unixDomainSocketPath: self.path).whenSuccess { (channel) in .. self.channel = channel } ... ... // Send some data. self.channel?.writeAndFlush(buffer).wait() Any guidance would be greatly appreciated.

I am experiencing issue - Phone16 cannot to connect to WPA3-Enterprise Transition Mode SSID on Wi-Fi 7 AP. While iphone17 do not have this issue. And I have already created ticket - FB20924263. Here are the details below: Product: iOS 26.1, Device Models: iPhone 16 (fails), iPhone 17 (works) Network: Wi-Fi 7 AP, 2.4 GHz and 6 GHz disabled, only 5 GHz enabled Feature Area: WPA3-Enterprise Transition Mode connectivity Expected Behavior: Both iPhone 16 and iPhone 17 running iOS 26.1 should successfully connect to a WPA3-Enterprise Transition Mode SSID when configured according to the standard. Actual Behavior: iPhone 16 (iOS 26.1) fails to connect to the SSID. iPhone 17 (iOS 26.1) connects successfully under the same conditions. Steps to Reproduce: Configure a Wi-Fi 7 AP: Disable 2.4 GHz and 6 GHz bands, keep only 5 GHz active. Add an SSID using WPA3-Enterprise Transition Mode. Attempt to connect with iPhone 16 (iOS 26.1) → fails. Attempt to connect with iPhone 17 (iOS 26.1) → succeeds. Additional Notes: When I disable 11be mode and make the DUT run under 11ax mode, then iPhone16 can also connect to the WPA3-Enterprise Transition Mode SSID As I’m a WiFi router developer, then I did one more thing, keep DUT under 11be mode, but do not enable MLO for that SSID (Remove MultiLink relate IE in beacon), then iPhone16 can also connect to the WPA3-Enterprise Transition Mode SSID It seems Iphone16 with Broadcom wifi chip solution has some specific policy for MLO + WPA3-Enterprise Transition Mode, while iphone17 with apple wifi chip solution do not add such limitation Also test other android devices and not found this issue

My app sent a network request to the backend. The backend returns a 200, but the front end received a -1001 or -1005 NSURLError. Any clue why this could be happening?

I am experiencing issue - iphone16/17 can't connect to the non-txvap SSID when the corresponding txvap is passpoint SSID. It may always fail to connect. But when I set the non-passpoint SSID as txvap and passpoint SSID as non-txvap, then iPhone16/17 can connect to the two SSID successfully. iPhone will add “HS20=1” flag for the non-passpoint SSID, then iPhone will ALWAYS not connect that SSID successfully. Please see the log below I captured from the issue iPhone. -[WFNetworkListController _updateViewControllerScanResults]_block_invoke: removing associationCtx network <WFNetworkScanRecord : 0xd34dec8c0 ssid='!wpa3-openwrt-mim6g' bssid='00:03:7f:12:cb:cd' rssi='-80' secured=1 eap=0 mode='WPA3 Personal' modeExt=['WPA3 Personal'] hidden=0 HS20=1 popular=0 known=0 privateAddressState=1> from scan results See detail in FB20923870 Is there anybody else meet this issue?

I'm using Network framework for communication between devices. The first time I instantiate an NWBrowser, it will prompt the user with a popup that says: Allow &lt;app name&gt; to find devices on local networks? The problem is, once I upgraded from Xcode 15.4 to Xcode 16.4, the popup doesn't appear; it says in the debug window: nw_browser_fail_on_dns_error_locked [B1] nw_browser_dns_service_browse_callback failed: PolicyDenied(18,446,744,073,709,486,046) I do have the info.plist keys Privacy-Local Network Usage Description (NSLocalNetworkUsageDescription) and Bonjour Services (NSBonjourServices) so it's not that. Also, It still works on a real device. I think something changed with Xcode 16 that tightened the security on a simulator, or maybe disabled Network framework entirely. It's not the firewall on my computer because that is turned off. I'm using an M1 MacBook Pro.

I am developing a program on my chip and attempting to establish a connection with the WiFi Aware demo app launched by iOS 26. Currently, I am encountering an issue during the pairing phase. If I am the subscriber of the service and successfully complete the follow-up frame exchange of pairing bootstrapping, I see the PIN code displayed by iOS. Question 1: How should I use this PIN code? Question 2: Subsequently, I need to negotiate keys with iOS through PASN. What should I use as the password for the PASN SAE process? If I am the subscriber of the service and successfully complete the follow-up frame exchange of pairing bootstrapping, I should display the PIN code. Question 3: How do I generate this PIN code? Question 4: Subsequently, I need to negotiate keys with iOS through PASN. What should I use as the password for the PASN SAE process?

So it seems the NetworkFramework is still not able to support Broastcast Mode am I correct? As soon as I switch broadcast mode to On in my game I receive console messages instead of receiving data. nw_path_evaluator_create_flow_inner failed NECP_CLIENT_ACTION_ADD_FLOW (null) evaluator parameters: udp, definite, server, attribution: developer, reuse local address, context: Default Network Context (private), proc: 2702288D-96FB-37DD-8610-A68CC526EA0F, local address: 0.0.0.0:20778 nw_path_evaluator_create_flow_inner NECP_CLIENT_ACTION_ADD_FLOW 1FB68D7E-7C9B-47B2-B6AC-E5710CD9C9CD [17: File exists] nw_endpoint_flow_setup_channel [C2 192.168.178.221:52716 initial channel-flow (satisfied (Path is satisfied), interface: en0[802.11], ipv4, ipv6, dns, uses wifi)] failed to request add nexus flow nw_endpoint_flow_failed_with_error [C2 192.168.178.221:52716 initial channel-flow (satisfied (Path is satisfied), interface: en0[802.11], ipv4, ipv6, dns, uses wifi)] already failing, returning nw_endpoint_handler_create_from_protocol_listener [C2 192.168.178.221:52716 failed channel-flow (satisfied (Path is satisfied), interface: en0[802.11], ipv4, ipv6, dns, uses wifi)] nw_endpoint_flow_pre_attach_protocols nw_connection_create_from_protocol_on_nw_queue [C2] Failed to create connection from listener nw_ip_channel_inbox_handle_new_flow nw_connection_create_from_protocol_on_nw_queue failed I won't be able to receive data which is a real shame, so I guess I am stuck with the lower level code: // Enable broadcast var enableBroadcast: Int32 = 1 if setsockopt(socketDescriptor, SOL_SOCKET, SO_BROADCAST, &enableBroadcast, socklen_t(MemoryLayout<Int32>.size)) == -1 { let errorMessage = String(cString: strerror(errno)) throw UDPSocketError.cannotEnableBroadcast(errorMessage) }

Hi, I’m trying to download a remote file in the background, but I keep getting a strange behaviour where URLSession download my file indefinitely during a few minutes, without calling urlSession(_:downloadTask:didFinishDownloadingTo:) until the download eventually times out. To find out that it’s looping, I’ve observed the total bytes written on disk by implementing urlSession(_:downloadTask:didWriteData:totalBytesWritten:totalBytesExpectedToWrite:). Note that I can't know the size of the file. The server is not able to calculate the size. Below is my implementation. I create an instance of URLSession like this: private lazy var session: URLSession = { let configuration = URLSessionConfiguration.background(withIdentifier: backgroundIdentifier) configuration.isDiscretionary = false configuration.sessionSendsLaunchEvents = true return URLSession(configuration: configuration, delegate: self, delegateQueue: nil) }() My service is using async/await so I have implemented an AsyncThrowingStream : private var downloadTask: URLSessionDownloadTask? private var continuation: AsyncThrowingStream&lt;(URL, URLResponse), Error&gt;.Continuation? private var stream: AsyncThrowingStream&lt;(URL, URLResponse), Error&gt; { AsyncThrowingStream&lt;(URL, URLResponse), Error&gt; { continuation in self.continuation = continuation self.continuation?.onTermination = { @Sendable [weak self] data in self?.downloadTask?.cancel() } downloadTask?.resume() } } Then to start the download, I do : private func download(with request: URLRequest) async throws -&gt; (URL, URLResponse) { do { downloadTask = session.downloadTask(with: request) for try await (url, response) in stream { return (url, response) } throw NetworkingError.couldNotBuildRequest } catch { throw error } } Then in the delegate : public func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didFinishDownloadingTo location: URL) { guard let response = downloadTask.response, downloadTask.error == nil, (response as? HTTPURLResponse)?.statusCode == 200 else { continuation?.finish(throwing: downloadTask.error) return } do { let documentsURL = try FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false) let savedURL = documentsURL.appendingPathComponent(location.lastPathComponent) try FileManager.default.moveItem(at: location, to: savedURL) continuation?.yield((savedURL, response)) continuation?.finish() } catch { continuation?.finish(throwing: error) } } I also tried to replace let configuration = URLSessionConfiguration.background(withIdentifier: backgroundIdentifier) by let configuration = URLSessionConfiguration.default and this time I get a different error at the end of the download: Task &lt;0457F755-9C52-4CFB-BDB2-F378D0C94912&gt;.&lt;1&gt; failed strict content length check - expected: 0, received: 530692, received (uncompressed): 0 Task &lt;0457F755-9C52-4CFB-BDB2-F378D0C94912&gt;.&lt;1&gt; finished with error [-1005] Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."

The download works fine in Chrome/Safari/Chrome or Postman. My code used to work a couple of weeks before, so I expect something has changed on the server side, but I can’t find what, and I don’t get much help from the guys on the server side. Has anyone an idea of what’s going on?

Issue summary: Iphone 16 is not connecting to WiFi7 AP with MLO Suiteb encryption. Furuno AP(EW750) is sending EAPOL M1 message, but Iphone16 is not responding with EAPOL M2 message, Hence Iphone16 is unable to connect to Qualcomm based AP with MLO suiteb encryption. Issue impact: All the Iphone16 users cannot connect to WiFi7 AP with MLO suiteb encryption globally. Predominantly, Iphone users tend to connect to more secured wifi networks using WPA3 suiteb encryption, hence many of the iphone users will experience the connectivity issue significantly. Topology: AP Hardware: Furuno WiFi7 AP(EW770) The Furuno WiFi7 AP uses Miami IPQ5332 with waikiki radio QCN9274 AP software: SPF12.2 CSU3 IPhone16 software: (18.3.1 or 18.5 ) Iphone16 wifi capabilities: 802.11 b/a/g/n/ac/ax/be Radius server details: Radius server: Laptop running with Ubuntu Radius package: 3.0.26dfsggit20220223.1.00ed0241fa-0ubuntu3.4 Version: 3.0.26 Steps: Power on the Wi-Fi 7 Access Point with the Miami chipset, and flash it with the SPF 12.2 CSU3 image. Enable both 5 GHz and 6 GHz radios on the AP. Enable MLO (Multi-Link Operation) in 6Ghz &amp; 5Ghz, set MLD address different from radio address and configure Suite-B (192-bit) encryption On the Linux laptop, set up the RADIUS server with EAP-TLS authentication method. Once the above steps are completed, take the iPhone 16 and follow the steps below to install the RADIUS client certificates on the device. On the sniffer laptop, switch the Wi-Fi adapter to monitor mode, configure the required channel, and begin packet capture. Check SSID is broadcasting, then connect the iPhone 16 to . Verify if the client (iPhone 16) connects to the SSID using WPA3-Enterprise, MLO, and Suite-B encryption by checking the wireless capture on both the AP and iPhone sides. Support needed from Apple team: We would request Apple team to analyse and enable the IPhone16 users to connect to advanced security WPA3 Suiteb by resolving the issue. Below is our analysis and observation for your reference. As per IEEE, MLD mac address can be set to the same or different from radio address, Iphone16 is not accepting EAPOL M1 message if source address(MLD) is different from radio address. IPhone16 is accepting EAPOL M1 if the source address(MLD) is set to the same as the radio address and responds with M2 message IPhone16 is not accepting EAPOL M1 if source address(MLD) set to different from radio address and fails to respond with M2 message

Hello, I have searched here on the forums for "WiFi Aware" and have read through just about every post. In a lot of them the person says they were able to get the example app https://developer.apple.com/documentation/wifiaware/building-peer-to-peer-apps working with their iOS devices. I, for some reason, am not able to get the example app to fully work. I am able to build the app and load the app onto two physical iPhone 12 minis (both are running iOS 26.0.1). I follow the steps shown at the link share above but I get stuck because I can't get past the "enter this pin code to connect" step. I make one device be a host of a simulation and the other device the viewer of a simulation. On each device I tap the "+" button. On the viewer device I tap the discovered device. On the host device I then see the pin. I then enter the pin on the viewer device. After this step nothing happens. My only choice on the viewer device is to tap "cancel" and exit the "enter the pin step". If I go into the actual device settings (Settings -> Privacy & Security -> Paired Devices) I see that the devices are "paired" but the app doesn't seem to think so. Are there some special settings I need to turn on for the app to work properly? In an attempt to figure out what was going wrong I took the example app and paired it down to just send back simple messages based on user button taps. These are my logs from when I start up the app and start one device as the hoster and one as the viewer.

Hi~ I implemented network filtering on iOS using NEFilterControlProvider and NEFilterDataProvider. However, I found that their usage is restricted when distributing through the App Store. Does ADEP-based distribution allow the use of NEFilterControlProvider and NEFilterDataProvider? In TN3134, it states that NEPacketTunnelProvider requires MDM. Should I assume that NEFilterControlProvider and NEFilterDataProvider also require MDM in the same way? Thanks

We are currently working on a zero-configuration networking compliant device thru avahi-daemon. Our Device want to have multiple Instance name for different services. Example InstanceA._ipps._tcp.local. InstanceA._ipp._tcp.local. InstanceB._ipps._tcp.local. InstanceB._ipp._tcp.local. Will BCT confuse this as multiple device connected in the network and cause it to fail? Does Bonjour only allows only a Single Instance name with multiple services?

We are developing an iOS application with a key feature designed to enhance user safety: real-time assessment of Wi-Fi network security. The "Safe Wi-Fi" feature aims to inform users about the security level of the Wi-Fi network they are currently connected to. Our goal is to provide this information seamlessly and continuously, even when the user isn't actively using the app. Currently, we've implemented this feature using a NWPathMonitor. The limitation of NWPathMonitor is that it doesn't function when the app is in a kill state. We are looking for guidance on how to achieve persistent Wi-Fi security monitoring in the background or when the app is killed. Is there any API (Public, Special API, etc) or a recommended approach that allows for real-time Wi-Fi connection monitoring (including connection changes and network details) even when the app is not actively running or is in a kill state. Thank you in advance for your help.

I have 3 phones iPhone 14 iOS 18.3 iPhone Xr iOS 18.5 iPhone Xr iOS 18.4.1 My app has a network extension, and I've noticed each phone having their connectivity interupted by calls on the push provider, calling stop with the noNetworkAvailable reason. The point of confusion is that each phone seems to get it's interuption at different times. For example one will get an interuption at 1:00, while the others is fine, while at 3:00 another will get an interuption, while the others are fine. This is confusing since a "no network available" seems to imply a problem with the router, or access point, but if that were the case, one would believe it should affect all the phones on the wifi. I don't see less interuptions on the iPhone14 vs the iPhone Xr. Do you believe the iOS version is affecting the performance? Could you please give me some insight, as to what could be going on inside these phones? P.S. I also see an error pop up when using NWConnection, this is inside the App. The state update handler will sometimes return the state, waiting(POSIX(.ENETDOWN)) Is there any relation to what's going on in the extension?

My application (using a nested framework for networking) was working correctly on iPadOS 18, but failed to perform a UDP broadcast operation after upgrading the device to iPadOS 26. The low-level console logs consistently show a "Permission denied" error. Symptoms & Error Message: When attempting to send a UDP broadcast packet using NWConnection (or a similar low-level socket call within the framework), the connection fails immediately with the following error logged in the console: nw_socket_service_writes_block_invoke [C2:1] sendmsg(fd 6, 124 bytes) [13: Permission denied] (Error code 13 corresponds to EACCES). Verification Steps (What I have checked): Multicast Networking Entitlement is Approved and Applied: The necessary entitlement (com.apple.developer.networking.multicast) was granted by Apple. The Provisioning Profile used for signing the Host App Target has been regenerated and explicitly includes "Multicast Networking" capability (see attached screenshot). I confirmed that Entitlements cannot be added directly to the Framework Target, only the Host App Target, which is the expected behavior. Local Network Privacy is Configured: The Host App's Info.plist contains the NSLocalNetworkUsageDescription key with a clear usage string. Crucially, the Local Network Access alert does not reliably appear when the Broadcast function is first called (despite a full reinstall after OS upgrade). Even when Local Network Access is manually enabled in Settings, the Broadcast still fails with EACCES. Code Implementation: The Broadcast is attempted using NWConnection to the host 255.255.255.255 on a specific port. Request: Since all required entitlements and profiles are correct, and the failure is a low-level EACCES on a newly updated OS version, I suspect this may be a regression bug in the iPadOS 26 security sandbox when validating the Multicast Networking Entitlement against a low-level socket call (like sendmsg). Has anyone else encountered this specific Permission denied error on iPadOS 26 with a valid Multicast Entitlement, and is there a known workaround aside from switching to mDNS/Bonjour?

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 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.

Question: What is the standard, most reliable way to manage temporary files associated with a URLSessionDownloadTask that has been terminated abnormally due to a network error or other issues? Details Hello, I'm currently developing a feature to download multiple files concurrently on iOS using URLSessionDownloadTask, and I have a question regarding the lifecycle of the temporary files created during this process. As I understand it, URLSessionDownloadTask stores incoming data in a temporary file within the tmp directory, typically with a name like CFNetworkDownload_*.tmp. In my testing, temporary files are managed correctly in the normal scenario. For instance, when I call the cancel() method on an active downloadTask and then release all references to it, the corresponding temporary file is automatically cleaned up from the tmp directory shortly after. However, the problem occurs when a download is interrupted abnormally due to external factors, such as a lost network connection. In this situation, the urlSession(_:task:didCompleteWithError:) delegate method is called, but the associated temporary file is not deleted and remains in the tmp directory. I've observed a particularly interesting behavior related to this. Immediately after the error occurs, if I check my app's storage usage in the iOS Settings app, the data size appears to have decreased momentarily. However, the tmp file has not actually been deleted, and after a short while, the storage usage is recalculated to include the size of this orphaned temporary file. Since my app does not support resuming interrupted downloads, these leftover files become orphaned and unnecessarily consume storage. Therefore, I want to ensure they are all reliably deleted. With this context, I'd like to ask the community: What is the standard, most reliable way to manage temporary files associated with a URLSessionDownloadTask that has been terminated abnormally due to a network error or other issues? I am wondering if there is an official guide or a framework-level API to handle these orphaned files. I would appreciate any advice from those with experience in this area. Thank you.

Hello, I am in a very similar situation as described in the thread: https://developer.apple.com/forums/thread/655183 Context: I am working on an app that receives data from a hardware device through its Wifi network, and the hardware is not connected to the internet. Now, I would need to call some API while still connected to hardware so I would need to use the cellular data. As mentioned on the thread, I can achieve this via Network framework, using the requiredInterfaceType property. But Is there any other way I can achieve this? I can also do some suggestion on the hardware if that's helpful. Thank you!
