Can't find server for API Endpoint that works.
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." UserInfo={_kCFStreamErrorCodeKey=-72000, NSUnderlyingError=0x1435783f0 {Error Domain=kCFErrorDomainCFNetwork Code=-1003 "(null)" UserInfo={_kCFStreamErrorDomainKey=10, _kCFStreamErrorCodeKey=-72000, _NSURLErrorNWResolutionReportKey=Resolved 0 endpoints in 3ms using unknown from query, _NSURLErrorNWPathKey=satisfied (Path is satisfied), interface: pdp_ip0[lte], ipv4, ipv6, dns, expensive, uses cell}}, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <91AE4DE0-2845-4348-89B4-D3DD1CF51B65>.<10>, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask <91AE4DE0-2845-4348-89B4-D3DD1CF51B65>.<10>" ), NSLocalizedDescription=A server with the specified hostname could not be found., NSErrorFailingURLStringKey=https://[my endpoint], NSErrorFailingURLKey=https://[my endpoint], _kCFStreamErrorDomainKey=10} I'm completely stuck because when I directly make https requests to other api's like openai's endpoint, without the proxy, it finds the server completely fine. 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 I've looked through almost every single post I could find online, but a lot all of the solutions are outdated and unhelpful.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.

Thread topology data: no API path for parent-child relationships
I'm building a HomeKit app that discovers Thread devices and visualizes the mesh topology. I can detect device roles (Router vs End Device via characteristic 0x0703) and identify Border Routers (via _meshcop._udp), but I cannot determine which Router is the parent of a given End Device. Any Thread device can act as a Router (a Nanoleaf bulb, an Eve plug, not just HomePods), and End Devices attach to these Routers as children. That parent-child relationship is what I'm trying to map, but there's no RLOC16, neighbor table, or parent identifier exposed through any available API. I've tested every path I can find. Here's what I've tried on a network with 44 Thread devices and 6 Border Routers: What works (partially) HAP Thread Management Service (0x0701) gives me the device role from characteristic 0x0703, the OpenThread version from 0x0706, and node capabilities from 0x0702. That's the complete set of characteristics on that service. None of them contain RLOC16, parent Router, or neighbor data. This service also only exists on HAP-native Thread devices. My 20 Matter-over-Thread devices (Aqara, Eve Door, SmartWings, Onvis S4) don't have it at all. MeshCoP Bonjour (_meshcop._udp) identifies Border Routers and the network name/Extended PAN ID. No topology data about other mesh nodes. What doesn't work ThreadNetwork framework (THClient) - retrieveAllCredentials() returns error Code 3 because the app can't access credentials stored by Apple Home. Even if it worked, THCredentials only contains network config (name, PAN ID, channel), not topology. Direct CoAP queries - Border Routers don't route traffic from WiFi to Thread management ports. Mesh-local addresses aren't reachable. No Thread NWInterface in Network.framework. Network.framework - No visibility into the Thread mesh from the WiFi side. The only remaining path I can see (but it's not practical) Matter cluster 0x0035 (Thread Network Diagnostics) appears to have exactly what I need: RLOC16, NeighborTable with isChild boolean, RouteTable. I haven't implemented this because it requires commissioning each device individually onto my app's own Matter fabric via Multi-Admin. That's 21 separate user-initiated pairing actions on my network. I can't ask end users to do that. The core issue Every Thread Router (whether it's a HomePod acting as a Border Router or a Nanoleaf bulb acting as a mesh Router) knows its own children and neighbors. The Border Routers also maintain route tables covering the mesh backbone. This data exists on the user's own devices but none of it is exposed to third-party apps. Even something minimal would help. HMAccessory already exposes matterNodeID as a cross-protocol identifier. Exposing RLOC16 the same way would be enough, since parent-child relationships are encoded in the address itself (ParentRLOC = ChildRLOC & 0xFC00). Has anyone found another approach I'm missing? Thanks in advance for any pointers.

My app attempts to use a socket to establish a connection with my external device, but it fails
My external device can generate a fixed Wi-Fi network. When I connect to this Wi-Fi using my iPhone 17 Pro Max (iOS version 26.0.1), and my app tries to establish a connection using the following method, this method returns -1 int connect(int, const struct sockaddr *, socklen_t) __DARWIN_ALIAS_C(connect); However, when I use other phones, such as iPhone 12, iPhone 8, iPhone 11, etc., to connect to this external device, the above method always returns successfully, with the parameters passed to the method remaining the same. I also tried resetting the network settings on the iPhone 17 Pro Max (iOS version 26.0.1), but it still cannot establish a connection.

Upgrading NEFilterDataProvider Causes System Network Interruption
Hi, when I perform an overlay installation via a PKG on macOS for an application containing the NEFilterDataProvider functionality, there is a chance that the entire system network becomes unreachable. Disabling the corresponding Content Filter in "System Settings > Network > Filters" immediately restores network connectivity. This issue does not occur every time, with a frequency of approximately 1 in 20 installation attempts.  The following details may help identify the problem: The Filter.app containing the NEFilterDataProvider resides within the main app's Resources directory, e.g., /Applications/Main.app/Contents/Resources/Filter.app Main.app is installed via a PKG; the issue typically occurs during an overlay installation of Main.app. The NEFilterDataProvider operates as a System Extension. The func handleNewFlow(_ flow: NEFilterFlow) -> NEFilterNewFlowVerdict {} returns .allow. Wireshark packet captures show TCP packets but no UDP packets; TCP handshakes cannot complete. Disabling the corresponding content filter in "System Settings > Network > Filters" restores the network; re-enabling it breaks connectivity again. After waiting for a period, approximately 30-60 minutes, network connectivity can recover automatically. What causes this and how can it be fixed? Any workarounds?

iOS26 captive portal detection changes?
Hi all, I work on a smart product that, for setup, uses a captive portal to allow users to connect and configure the device. It emits a WiFi network and runs a captive portal - an HTTP server operates at 10.0.0.1, and a DNS server responds to all requests with 10.0.0.1 to direct "any and all" request to the server. When iOS devices connect, they send a request to captive.apple.com/hotspot-detect.html; if it returns success, that means they're on the internet; if not, the typical behavior in the past has been to assume you're connected to a captive portal and display what's being served. I serve any requests to /hotspot-detect.html with my captive portal page (index.html). This has worked reliably on iOS18 for a long time (user selects my products WiFi network, iOS detects portal and opens it). But almost everyone who's now trying with iOS26 is having the "automatic pop up" behavior fail - usually it says "Error opening page - Hotspot login cannot open the page because the network connection was lost." However, if opening safari and navigating to any URL (or 10.0.0.1) the portal loads - it's just the iOS auto-detect and open that's not working iOS18 always succeeds; iOS26 always fails. Anybody have any idea what changes may have been introduced in iOS26 on this front, or anything I can do to help prompt or coax iOS26 into loading the portal? It typically starts reading, but then stops mid-read.

[iOS 26] Unable to start TLS handshake connection to devices with self-signed certificates
Hi there, We are facing some issues regarding TLS connectivity: Starting with iOS 26, the operating system refuses to open TLS sockets to local devices with self-signed certificates over Wi-Fi. In this situation, connection is no longer possible, even if the device is detected on the network with Bonjour. We have not found a workaround for this problem. We've tryied those solutions without success: Added the 'NSAppTransportSecurity' key to the info.plist file, testing all its items, such as "NSAllowsLocalNetworking", "NSExceptionDomains", etc. Various code changes to use properties such as "sec_protocol_options_set_local_identity" and "sec_protocol_options_set_tls_server_name" to no avail. Brutally import the certificate files into the project and load them via, for example, "Bundle.main.url(forResource: "nice_INTERFACE_server_cert", withExtension: "crt")", using methods such as sec_trust_copy_ref and SecCertificateCopyData. Download the .pem or .crt files to the iPhone, install them (now visible under "VPN & Device Management"), and then flag them as trusted by going to "Settings -> General -> Info -> Trust". certificates" The most critical part seems to be the line sec_protocol_options_set_verify_block(tlsOptions.securityProtocolOptions, { $2(true) }, queue) whose purpose is to bypass certificate checks and validate all of them (as apps already do). However, on iOS26, if I set a breakpoint on leg$2(true),` it never gets there, while on iOS 18, it does. I'll leave as example the part of the code that was tested the most below. Currently, on iOS26, the handler systematically falls back to .cancelled: func startConnection(host: String, port: UInt16) { self.queue = DispatchQueue(label: "socketQueue") let tlsOptions = NWProtocolTLS.Options() sec_protocol_options_set_verify_block(tlsOptions.securityProtocolOptions, { $2(true) }, queue) let parameters = NWParameters(tls: tlsOptions) self.nwConnection = NWConnection(host: .init(host), port: .init(rawValue: port)!, using: parameters) self.nwConnection.stateUpdateHandler = { [weak self] state in switch state { case .setup: break case .waiting(let error): self?.connectionDidFail(error: error) case .preparing: break case .ready: self?.didConnectSubject.onNext(Void()) case .failed(let error): self?.connectionDidFail(error: error) case .cancelled: self?.didDisconnectSubject.onNext(nil) @unknown default: break } } self.setupReceive() self.nwConnection.start(queue: queue) } These are the prints made during the procedure. The ones with the dot are from the app, while the ones without are warnings/info from Xcode: 🔵 INFO WifiNetworkManager.connect():52 - Try to connect onto the interface access point with ssid NiceProView4A9151_AP 🔵 INFO WifiNetworkManager.connect():68 - Connected to NiceProView4A9151_AP tcp_output [C13:2] flags=[R.] seq=215593821, ack=430284980, win=4096 state=CLOSED rcv_nxt=430284980, snd_una=215593821 nw_endpoint_flow_failed_with_error [C13 192.168.0.1:443 in_progress channel-flow (satisfied (Path is satisfied), viable, interface: en0[802.11], dns, uses wifi, LQM: unknown)] already failing, returning nw_connection_copy_protocol_metadata_internal_block_invoke [C13] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_protocol_metadata_internal_block_invoke [C13] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_connected_local_endpoint_block_invoke [C13] Client called nw_connection_copy_connected_local_endpoint on unconnected nw_connection nw_connection_copy_connected_remote_endpoint_block_invoke [C13] Client called nw_connection_copy_connected_remote_endpoint on unconnected nw_connection nw_connection_copy_protocol_metadata_internal_block_invoke [C14] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_protocol_metadata_internal_block_invoke [C14] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_connected_local_endpoint_block_invoke [C14] Client called nw_connection_copy_connected_local_endpoint on unconnected nw_connection nw_connection_copy_connected_remote_endpoint_block_invoke [C14] Client called nw_connection_copy_connected_remote_endpoint on unconnected nw_connection [C14 192.168.0.1:443 tcp, tls, attribution: developer] is already cancelled, ignoring cancel [C14 192.168.0.1:443 tcp, tls, attribution: developer] is already cancelled, ignoring cancel nw_connection_copy_protocol_metadata_internal_block_invoke [C15] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_protocol_metadata_internal_block_invoke [C15] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_connected_local_endpoint_block_invoke [C15] Client called nw_connection_copy_connected_local_endpoint on unconnected nw_connection nw_connection_copy_connected_remote_endpoint_block_invoke [C15] Client called nw_connection_copy_connected_remote_endpoint on unconnected nw_connection nw_connection_copy_protocol_metadata_internal_block_invoke [C16] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_protocol_metadata_internal_block_invoke [C16] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_connected_local_endpoint_block_invoke [C16] Client called nw_connection_copy_connected_local_endpoint on unconnected nw_connection nw_connection_copy_connected_remote_endpoint_block_invoke [C16] Client called nw_connection_copy_connected_remote_endpoint on unconnected nw_connection [C16 192.168.0.1:443 tcp, tls, attribution: developer] is already cancelled, ignoring cancel [C16 192.168.0.1:443 tcp, tls, attribution: developer] is already cancelled, ignoring cancel 🔴 ERROR InterfaceDisconnectedViewModel.connect():51 - Sequence timeout.

NEAppPushProvider not works properly on iOS26
In my app I have Local Push connectivity for local push notifications. My app has proper entitlment granted by Apple and NEAppPushProvider was working perfectly on older iOS versions before iOS26. The problem I faced with iOS26: when i enable VPN - NEAppPushProvider stops with reason /** @const NEProviderStopReasonNoNetworkAvailable There is no network connectivity. */ case noNetworkAvailable = 3. But device is still connected to proper SSID that is included to matchSSIDs. I discovered it only happens if my VPN config file include this line redirect-gateway def1 without that line NEAppPushProvider works as expected with enabled VPN. I use OpenVPN app. Is it a bug of iOS26 or I need some additional setup? Please help!

WiFi aware demo paring issue
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?

How to configure macOS app permission MANUALLY (not GUI)
I need to run multiple, slightly different copies of a modeling tool, which all need access to a model repository on a different machine. Security Settings -> Network tends to pick one modeling tool (and unfortunately the wrong one) for permission, but the dialog offers no way to add the other copies manually. Where can I configure the permission on low level. [macOS Sequoia 15.6.1]

How can a Network Extension notify or trigger tasks in the main app when it’s backgrounded or killed?
I’m developing a iOS VPN app, and I need to execute a task in the main app even when it’s in the background or killed state. I know the Network Extension continues running during those times. Is there a way for the extension to immediately notify the app or trigger a task on the app side?

Verifying TLS 1.3 early_data behavior on iOS 26
Development environment Xcode 26.0 Beta 6 iOS 26 Simulator macOS 15.6.1 To verify TLS 1.3 session resumption behavior in URLSession, I configured URLSessionConfiguration as follows and sent an HTTP GET request: let config = URLSessionConfiguration.ephemeral config.tlsMinimumSupportedProtocolVersion = .TLSv13 config.tlsMaximumSupportedProtocolVersion = .TLSv13 config.httpMaximumConnectionsPerHost = 1 config.httpAdditionalHeaders = ["Connection": "close"] config.enablesEarlyData = true let session = URLSession(configuration: config, delegate: nil, delegateQueue: nil) let url = URL(string: "https://www.google.com")! var request = URLRequest(url: url) request.assumesHTTP3Capable = true request.httpMethod = "GET" let task = session.dataTask(with: request) { data, response, error in if let error = error { print("Error during URLSession data task: \(error)") return } if let data = data, let responseString = String(data: data, encoding: .utf8) { print("Received data via URLSession: \(responseString)") } else { print("No data received or data is not UTF-8 encoded") } } task.resume() However, after capturing the packets, I found that the ClientHello packet did not include the early_data extension. It seems that enablesEarlyData on URLSessionConfiguration is not being applied. How can I make this work properly?

DMG Distribution for macOS App with App Extension — Should I Use System Extension Instead?
Hi everyone, I’m currently developing a macOS app that is distributed via a DMG file on our website. The app includes an App Extension (appex) for Network Extension functionality. I’m wondering if distributing via DMG on the web requires the app extension to be implemented as a System Extension instead of an App Extension. Is it necessary to migrate to System Extension for web-based DMG distribution, or can I continue using App Extension as is? Any insights or recommendations would be greatly appreciated. Thank you!

Can't find server for API Endpoint that works.
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." UserInfo={_kCFStreamErrorCodeKey=-72000, NSUnderlyingError=0x1435783f0 {Error Domain=kCFErrorDomainCFNetwork Code=-1003 "(null)" UserInfo={_kCFStreamErrorDomainKey=10, _kCFStreamErrorCodeKey=-72000, _NSURLErrorNWResolutionReportKey=Resolved 0 endpoints in 3ms using unknown from query, _NSURLErrorNWPathKey=satisfied (Path is satisfied), interface: pdp_ip0[lte], ipv4, ipv6, dns, expensive, uses cell}}, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <91AE4DE0-2845-4348-89B4-D3DD1CF51B65>.<10>, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask <91AE4DE0-2845-4348-89B4-D3DD1CF51B65>.<10>" ), NSLocalizedDescription=A server with the specified hostname could not be found., NSErrorFailingURLStringKey=https://[my endpoint], NSErrorFailingURLKey=https://[my endpoint], _kCFStreamErrorDomainKey=10} I'm completely stuck because when I directly make https requests to other api's like openai's endpoint, without the proxy, it finds the server completely fine. 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.

Thread topology data: no API path for parent-child relationships
I'm building a HomeKit app that discovers Thread devices and visualizes the mesh topology. I can detect device roles (Router vs End Device via characteristic 0x0703) and identify Border Routers (via _meshcop._udp), but I cannot determine which Router is the parent of a given End Device. Any Thread device can act as a Router (a Nanoleaf bulb, an Eve plug, not just HomePods), and End Devices attach to these Routers as children. That parent-child relationship is what I'm trying to map, but there's no RLOC16, neighbor table, or parent identifier exposed through any available API. I've tested every path I can find. Here's what I've tried on a network with 44 Thread devices and 6 Border Routers: What works (partially) HAP Thread Management Service (0x0701) gives me the device role from characteristic 0x0703, the OpenThread version from 0x0706, and node capabilities from 0x0702. That's the complete set of characteristics on that service. None of them contain RLOC16, parent Router, or neighbor data. This service also only exists on HAP-native Thread devices. My 20 Matter-over-Thread devices (Aqara, Eve Door, SmartWings, Onvis S4) don't have it at all. MeshCoP Bonjour (_meshcop._udp) identifies Border Routers and the network name/Extended PAN ID. No topology data about other mesh nodes. What doesn't work ThreadNetwork framework (THClient) - retrieveAllCredentials() returns error Code 3 because the app can't access credentials stored by Apple Home. Even if it worked, THCredentials only contains network config (name, PAN ID, channel), not topology. Direct CoAP queries - Border Routers don't route traffic from WiFi to Thread management ports. Mesh-local addresses aren't reachable. No Thread NWInterface in Network.framework. Network.framework - No visibility into the Thread mesh from the WiFi side. The only remaining path I can see (but it's not practical) Matter cluster 0x0035 (Thread Network Diagnostics) appears to have exactly what I need: RLOC16, NeighborTable with isChild boolean, RouteTable. I haven't implemented this because it requires commissioning each device individually onto my app's own Matter fabric via Multi-Admin. That's 21 separate user-initiated pairing actions on my network. I can't ask end users to do that. The core issue Every Thread Router (whether it's a HomePod acting as a Border Router or a Nanoleaf bulb acting as a mesh Router) knows its own children and neighbors. The Border Routers also maintain route tables covering the mesh backbone. This data exists on the user's own devices but none of it is exposed to third-party apps. Even something minimal would help. HMAccessory already exposes matterNodeID as a cross-protocol identifier. Exposing RLOC16 the same way would be enough, since parent-child relationships are encoded in the address itself (ParentRLOC = ChildRLOC & 0xFC00). Has anyone found another approach I'm missing? Thanks in advance for any pointers.

My app attempts to use a socket to establish a connection with my external device, but it fails
My external device can generate a fixed Wi-Fi network. When I connect to this Wi-Fi using my iPhone 17 Pro Max (iOS version 26.0.1), and my app tries to establish a connection using the following method, this method returns -1 int connect(int, const struct sockaddr *, socklen_t) __DARWIN_ALIAS_C(connect); However, when I use other phones, such as iPhone 12, iPhone 8, iPhone 11, etc., to connect to this external device, the above method always returns successfully, with the parameters passed to the method remaining the same. I also tried resetting the network settings on the iPhone 17 Pro Max (iOS version 26.0.1), but it still cannot establish a connection.

Upgrading NEFilterDataProvider Causes System Network Interruption
Hi, when I perform an overlay installation via a PKG on macOS for an application containing the NEFilterDataProvider functionality, there is a chance that the entire system network becomes unreachable. Disabling the corresponding Content Filter in "System Settings > Network > Filters" immediately restores network connectivity. This issue does not occur every time, with a frequency of approximately 1 in 20 installation attempts.  The following details may help identify the problem: The Filter.app containing the NEFilterDataProvider resides within the main app's Resources directory, e.g., /Applications/Main.app/Contents/Resources/Filter.app Main.app is installed via a PKG; the issue typically occurs during an overlay installation of Main.app. The NEFilterDataProvider operates as a System Extension. The func handleNewFlow(_ flow: NEFilterFlow) -> NEFilterNewFlowVerdict {} returns .allow. Wireshark packet captures show TCP packets but no UDP packets; TCP handshakes cannot complete. Disabling the corresponding content filter in "System Settings > Network > Filters" restores the network; re-enabling it breaks connectivity again. After waiting for a period, approximately 30-60 minutes, network connectivity can recover automatically. What causes this and how can it be fixed? Any workarounds?

iOS26 captive portal detection changes?
Hi all, I work on a smart product that, for setup, uses a captive portal to allow users to connect and configure the device. It emits a WiFi network and runs a captive portal - an HTTP server operates at 10.0.0.1, and a DNS server responds to all requests with 10.0.0.1 to direct "any and all" request to the server. When iOS devices connect, they send a request to captive.apple.com/hotspot-detect.html; if it returns success, that means they're on the internet; if not, the typical behavior in the past has been to assume you're connected to a captive portal and display what's being served. I serve any requests to /hotspot-detect.html with my captive portal page (index.html). This has worked reliably on iOS18 for a long time (user selects my products WiFi network, iOS detects portal and opens it). But almost everyone who's now trying with iOS26 is having the "automatic pop up" behavior fail - usually it says "Error opening page - Hotspot login cannot open the page because the network connection was lost." However, if opening safari and navigating to any URL (or 10.0.0.1) the portal loads - it's just the iOS auto-detect and open that's not working iOS18 always succeeds; iOS26 always fails. Anybody have any idea what changes may have been introduced in iOS26 on this front, or anything I can do to help prompt or coax iOS26 into loading the portal? It typically starts reading, but then stops mid-read.

[iOS 26] Unable to start TLS handshake connection to devices with self-signed certificates
Hi there, We are facing some issues regarding TLS connectivity: Starting with iOS 26, the operating system refuses to open TLS sockets to local devices with self-signed certificates over Wi-Fi. In this situation, connection is no longer possible, even if the device is detected on the network with Bonjour. We have not found a workaround for this problem. We've tryied those solutions without success: Added the 'NSAppTransportSecurity' key to the info.plist file, testing all its items, such as "NSAllowsLocalNetworking", "NSExceptionDomains", etc. Various code changes to use properties such as "sec_protocol_options_set_local_identity" and "sec_protocol_options_set_tls_server_name" to no avail. Brutally import the certificate files into the project and load them via, for example, "Bundle.main.url(forResource: "nice_INTERFACE_server_cert", withExtension: "crt")", using methods such as sec_trust_copy_ref and SecCertificateCopyData. Download the .pem or .crt files to the iPhone, install them (now visible under "VPN & Device Management"), and then flag them as trusted by going to "Settings -> General -> Info -> Trust". certificates" The most critical part seems to be the line sec_protocol_options_set_verify_block(tlsOptions.securityProtocolOptions, { $2(true) }, queue) whose purpose is to bypass certificate checks and validate all of them (as apps already do). However, on iOS26, if I set a breakpoint on leg$2(true),` it never gets there, while on iOS 18, it does. I'll leave as example the part of the code that was tested the most below. Currently, on iOS26, the handler systematically falls back to .cancelled: func startConnection(host: String, port: UInt16) { self.queue = DispatchQueue(label: "socketQueue") let tlsOptions = NWProtocolTLS.Options() sec_protocol_options_set_verify_block(tlsOptions.securityProtocolOptions, { $2(true) }, queue) let parameters = NWParameters(tls: tlsOptions) self.nwConnection = NWConnection(host: .init(host), port: .init(rawValue: port)!, using: parameters) self.nwConnection.stateUpdateHandler = { [weak self] state in switch state { case .setup: break case .waiting(let error): self?.connectionDidFail(error: error) case .preparing: break case .ready: self?.didConnectSubject.onNext(Void()) case .failed(let error): self?.connectionDidFail(error: error) case .cancelled: self?.didDisconnectSubject.onNext(nil) @unknown default: break } } self.setupReceive() self.nwConnection.start(queue: queue) } These are the prints made during the procedure. The ones with the dot are from the app, while the ones without are warnings/info from Xcode: 🔵 INFO WifiNetworkManager.connect():52 - Try to connect onto the interface access point with ssid NiceProView4A9151_AP 🔵 INFO WifiNetworkManager.connect():68 - Connected to NiceProView4A9151_AP tcp_output [C13:2] flags=[R.] seq=215593821, ack=430284980, win=4096 state=CLOSED rcv_nxt=430284980, snd_una=215593821 nw_endpoint_flow_failed_with_error [C13 192.168.0.1:443 in_progress channel-flow (satisfied (Path is satisfied), viable, interface: en0[802.11], dns, uses wifi, LQM: unknown)] already failing, returning nw_connection_copy_protocol_metadata_internal_block_invoke [C13] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_protocol_metadata_internal_block_invoke [C13] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_connected_local_endpoint_block_invoke [C13] Client called nw_connection_copy_connected_local_endpoint on unconnected nw_connection nw_connection_copy_connected_remote_endpoint_block_invoke [C13] Client called nw_connection_copy_connected_remote_endpoint on unconnected nw_connection nw_connection_copy_protocol_metadata_internal_block_invoke [C14] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_protocol_metadata_internal_block_invoke [C14] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_connected_local_endpoint_block_invoke [C14] Client called nw_connection_copy_connected_local_endpoint on unconnected nw_connection nw_connection_copy_connected_remote_endpoint_block_invoke [C14] Client called nw_connection_copy_connected_remote_endpoint on unconnected nw_connection [C14 192.168.0.1:443 tcp, tls, attribution: developer] is already cancelled, ignoring cancel [C14 192.168.0.1:443 tcp, tls, attribution: developer] is already cancelled, ignoring cancel nw_connection_copy_protocol_metadata_internal_block_invoke [C15] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_protocol_metadata_internal_block_invoke [C15] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_connected_local_endpoint_block_invoke [C15] Client called nw_connection_copy_connected_local_endpoint on unconnected nw_connection nw_connection_copy_connected_remote_endpoint_block_invoke [C15] Client called nw_connection_copy_connected_remote_endpoint on unconnected nw_connection nw_connection_copy_protocol_metadata_internal_block_invoke [C16] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_protocol_metadata_internal_block_invoke [C16] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection nw_connection_copy_connected_local_endpoint_block_invoke [C16] Client called nw_connection_copy_connected_local_endpoint on unconnected nw_connection nw_connection_copy_connected_remote_endpoint_block_invoke [C16] Client called nw_connection_copy_connected_remote_endpoint on unconnected nw_connection [C16 192.168.0.1:443 tcp, tls, attribution: developer] is already cancelled, ignoring cancel [C16 192.168.0.1:443 tcp, tls, attribution: developer] is already cancelled, ignoring cancel 🔴 ERROR InterfaceDisconnectedViewModel.connect():51 - Sequence timeout.

NEAppPushProvider not works properly on iOS26
In my app I have Local Push connectivity for local push notifications. My app has proper entitlment granted by Apple and NEAppPushProvider was working perfectly on older iOS versions before iOS26. The problem I faced with iOS26: when i enable VPN - NEAppPushProvider stops with reason /** @const NEProviderStopReasonNoNetworkAvailable There is no network connectivity. */ case noNetworkAvailable = 3. But device is still connected to proper SSID that is included to matchSSIDs. I discovered it only happens if my VPN config file include this line redirect-gateway def1 without that line NEAppPushProvider works as expected with enabled VPN. I use OpenVPN app. Is it a bug of iOS26 or I need some additional setup? Please help!

WiFi aware demo paring issue
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?

How to configure macOS app permission MANUALLY (not GUI)
I need to run multiple, slightly different copies of a modeling tool, which all need access to a model repository on a different machine. Security Settings -> Network tends to pick one modeling tool (and unfortunately the wrong one) for permission, but the dialog offers no way to add the other copies manually. Where can I configure the permission on low level. [macOS Sequoia 15.6.1]

Development environment Xcode 26.0 Beta 6 iOS 26 Simulator macOS 15.6.1 To verify TLS 1.3 session resumption behavior in URLSession, I configured URLSessionConfiguration as follows and sent an HTTP GET request: let config = URLSessionConfiguration.ephemeral config.tlsMinimumSupportedProtocolVersion = .TLSv13 config.tlsMaximumSupportedProtocolVersion = .TLSv13 config.httpMaximumConnectionsPerHost = 1 config.httpAdditionalHeaders = ["Connection": "close"] config.enablesEarlyData = true let session = URLSession(configuration: config, delegate: nil, delegateQueue: nil) let url = URL(string: "https://www.google.com")! var request = URLRequest(url: url) request.assumesHTTP3Capable = true request.httpMethod = "GET" let task = session.dataTask(with: request) { data, response, error in if let error = error { print("Error during URLSession data task: \(error)") return } if let data = data, let responseString = String(data: data, encoding: .utf8) { print("Received data via URLSession: \(responseString)") } else { print("No data received or data is not UTF-8 encoded") } } task.resume() However, after capturing the packets, I found that the ClientHello packet did not include the early_data extension. It seems that enablesEarlyData on URLSessionConfiguration is not being applied. How can I make this work properly?

DMG Distribution for macOS App with App Extension — Should I Use System Extension Instead?
Hi everyone, I’m currently developing a macOS app that is distributed via a DMG file on our website. The app includes an App Extension (appex) for Network Extension functionality. I’m wondering if distributing via DMG on the web requires the app extension to be implemented as a System Extension instead of an App Extension. Is it necessary to migrate to System Extension for web-based DMG distribution, or can I continue using App Extension as is? Any insights or recommendations would be greatly appreciated. Thank you!
