I have added a Network Extension to my iOS project to use the WireGuard library. Everything was working fine up to Xcode 16, but after updating, I’m facing a build issue. The build fails with the following error: No such file or directory: '@rpath/WireGuardNetworkExtensioniOS.debug.dylib' I haven’t explicitly added any .dylib to my project. The Network Extension target builds and runs fine on Xcode 16.

I was excited to find out about Wi-Fi Aware in i[Pad]OS 26 and was eager to experiment with it. But after wiping and updating two devices (an iPhone 11 Pro and a 2018 11" iPad Pro) to Beta 1 I found out that neither of them support Wi-Fi Aware 🙁. What current and past iPhone and iPad models support Wi-Fi Aware? And is there a new UIRequiredDeviceCapabilities key for it, to indicate that an app requires a Wi-Fi Aware capable device?

I'm working on a Network Extension using NEDNSProxyProvider to inspect DNS traffic. However, I've run into a couple of issues: DNS Proxy is not capturing traffic when a public DNS (like 8.8.8.8 or 1.1.1.1) is manually configured in the WiFi settings. It seems like the system bypasses the proxy in this case. Is this expected behavior? Is there a way to force DNS traffic through the proxy even if a public DNS is set? Using DNS Proxy and DNS Settings simultaneously doesn't work. Is there a known limitation or a correct way to combine these? How to set DNS or DNSSettings using DNSProxy? import NetworkExtension import SystemExtensions import SwiftUI protocol DNSProxyManagerDelegate { func managerStateDidChange(_ manager: DNSProxyManager) } class DNSProxyManager: NSObject { private let manager = NEDNSProxyManager.shared() var delegate: DNSProxyManagerDelegate? private(set) var isEnabled: Bool = false { didSet { delegate?.managerStateDidChange(self) } } var completion: (() -> Void)? override init() { super.init() self.load() } func toggle() { isEnabled ? disable() : start() } private func start() { let request = OSSystemExtensionRequest .activationRequest(forExtensionWithIdentifier: Constants.extensionBundleID, queue: DispatchQueue.main) request.delegate = self OSSystemExtensionManager.shared.submitRequest(request) log.info("Submitted extension activation request") } private func enable() { update { self.manager.localizedDescription = "DNS Proxy" let proto = NEDNSProxyProviderProtocol() proto.providerBundleIdentifier = Constants.extensionBundleID self.manager.providerProtocol = proto self.manager.isEnabled = true } } private func disable() { update { self.manager.isEnabled = false } } private func remove() { update { self.manager.removeFromPreferences { _ in self.isEnabled = self.manager.isEnabled } } } private func update(_ body: @escaping () -> Void) { self.manager.loadFromPreferences { (error) in if let error = error { log.error("Failed to load DNS manager: \(error)") return } self.manager.saveToPreferences { (error) in if let error = error { return } log.info("Saved DNS manager") self.isEnabled = self.manager.isEnabled } } } private func load() { manager.loadFromPreferences { error in guard error == nil else { return } self.isEnabled = self.manager.isEnabled } } } extension DNSProxyManager: OSSystemExtensionRequestDelegate { func requestNeedsUserApproval(_ request: OSSystemExtensionRequest) { log.info("Extension activation request needs user approval") } func request(_ request: OSSystemExtensionRequest, didFailWithError error: Error) { log.error("Extension activation request failed: \(error)") } func request(_ request: OSSystemExtensionRequest, foundProperties properties: [OSSystemExtensionProperties]) { log.info("Extension activation request found properties: \(properties)") } func request(_ request: OSSystemExtensionRequest, didFinishWithResult result: OSSystemExtensionRequest.Result) { guard result == .completed else { log.error("Unexpected result \(result.description) for system extension request") return } log.info("Extension activation request did finish with result: \(result.description)") enable() } func request(_ request: OSSystemExtensionRequest, actionForReplacingExtension existing: OSSystemExtensionProperties, withExtension ext: OSSystemExtensionProperties) -> OSSystemExtensionRequest.ReplacementAction { log.info("Existing extension willt be replaced: \(existing.bundleIdentifier) -> \(ext.bundleIdentifier)") return .replace } } import NetworkExtension class DNSProxyProvider: NEDNSProxyProvider { var handlers: [String: FlowHandler] = [:] var isReady = false let queue = DispatchQueue(label: "DNSProxyProvider") override func startProxy(options:[String: Any]? = nil, completionHandler: @escaping (Error?) -> Void) { completionHandler(nil) } override func stopProxy(with reason: NEProviderStopReason, completionHandler: @escaping () -> Void) { completionHandler() } override func handleNewUDPFlow(_ flow: NEAppProxyUDPFlow, initialRemoteEndpoint remoteEndpoint: NWEndpoint) -> Bool { let id = shortUUID() handlers[id] = FlowHandler(flow: flow, remoteEndpoint: remoteEndpoint, id: id, delegate: self) return true } override func handleNewFlow(_ flow: NEAppProxyFlow) -> Bool { return false } } class FlowHandler { let id: String let flow: NEAppProxyUDPFlow let remoteEndpoint: NWHostEndpoint let delegate: FlowHandlerDelegate private var connections: [String: RemoteConnection] = [:] private var pendingPacketsByDomain: [String: [(packet: Data, endpoint: NWEndpoint, uniqueID: String, timestamp: Date)]] = [:] private let packetQueue = DispatchQueue(label: "com.flowhandler.packetQueue") init(flow: NEAppProxyUDPFlow, remoteEndpoint: NWEndpoint, id: String, delegate: FlowHandlerDelegate) { log.info("Flow received for \(id) flow: \(String(describing: flow))") self.flow = flow self.remoteEndpoint = remoteEndpoint as!

When setting up a packet tunnel with a profile that has includeAllNetworks set to true, we seemingly cannot send any traffic inside the tunnel using any kind of an API. We've tried using BSD sockets, as we ping a host only reachable within the tunnel to establish whether we have connectivity - this does not work. When using NWConnection from the Network framework and specifying the required interface via virtualInterface from the packet tunnel, the connection state never reaches ready. Our interim solution is to, as ridiculous as it sounds, include a whole userspace networking stack so we can produce valid TCP packets just to send into our own tunnel. We require a TCP connection within our own tunnel to do some configuration during tunnel setup. Is there no better solution?

For years our iOS apps have experienced a networking problem, which blocks them connecting to our servers via their API endpoint domains. How can we recover after the scenario described below? Using 3rd party error logging solutions, which have different endpoint domains, we can record the error: NSUnderlyingError": Error Domain=kCFErrorDomainCFNetwork Code=-1200 "(null)" UserInfo={_kCFStreamPropertySSLClientCertificateState=0, _kCFNetworkCFStreamSSLErrorOriginalValue=-9816, _kCFStreamErrorDomainKey=3, _kCFStreamErrorCodeKey=-9816, _NSURLErrorNWPathKey=satisfied (Path is satisfied), viable, interface: pdp_ip0[lte], ipv4, dns, expensive, uses cell}, "_NSURLErrorFailingURLSessionTaskErrorKey": LocalDataTask <DEDBFA4D-810D-4438-A6A0-95E3B9668B9E>.<308>, "_kCFStreamErrorDomainKey": 3, "_NSURLErrorRelatedURLSessionTaskErrorKey": <__NSSingleObjectArrayI 0x301f82e60>( LocalDataTask <DEDBFA4D-810D-4438-A6A0-95E3B9668B9E>.<308> ) "NSLocalizedDescription": An SSL error has occurred and a secure connection to the server cannot be made., "NSLocalizedRecoverySuggestion": Would you like to connect to the server anyway? -9816 is the "server closed session with no notification" error based on comments in CoreFoundation source files. Subsequent API endpoint calls to the same domain return the same error. The SSL error occurs most prevalently after a server outage. However, despite our best efforts, we have been unable to replicate triggering the problem for development purposes via experiments with our server. When the error occurs the users report that: Fully closing (i.e. not just sending to background) and reopening the app does NOT clear connectivity to our server being blocked. Problem seems more prevalent when using mobile/cell data. Switching from mobile/cell data to WIFI resolves the connection problem and then switching back to mobile/cell data shows the problem again. So the underlying problem is not cleared. All other apps on the same device and mobile/cell data or WIFI connection, like Safari, have no problems connecting to the Internet. Deleting and reinstalling, or updating (when an update is available) resolves the problem. Or after waiting a few days the problem seems to resolve itself. The last two point above suggest that something is persisted/cached in the app preventing it from connecting properly with subsequent network attempts. Notes: We have one shared instance of the URLSession in the app for its networking because we are aware of the perils of multiple URLSession instances. We recently added conditions to call the URLSession await reset() method when detecting the SLL errors before repeating the request. It is debatable whether this reduces the problem as we still see logged cases with the subsequent requests hitting the same -9816 error. URLSession configuration: let config = URLSessionConfiguration.default config.timeoutIntervalForResource = 22 config.timeoutIntervalForRequest = 20 config.requestCachePolicy = .reloadIgnoringLocalCacheData config.urlCache = nil

Hi there, We’re developing a companion app for a smart home product that communicates over the user’s local network. To provision the device, it initially creates its own Wi-Fi network. The user joins this temporary network and enters their home Wi-Fi credentials via our app. The app then sends those credentials directly to the device, which stores them and connects to the local network for normal operation. We’re using AccessorySetupKit to discover nearby devices (via SSID prefix) and NEHotspotManager to join the accessory’s Wi-Fi network once the user selects it. This workflow works well in general. However, we’ve encountered a problem: if the user factory-resets the accessory, or needs to restart setup (for example, after entering the wrong Wi-Fi password), the device no longer appears in the accessory picker. In iOS 18, we were able to work around this by calling removeAccessory() after the device is selected. This forces the picker to always display the accessory again. But in iOS 26, a new confirmation dialog now appears when calling removeAccessory(), which confuses users during setup. We’re looking for a cleaner way to handle this scenario — ideally a way to make the accessory rediscoverable without prompting the user to confirm removal. Thanks for your time and guidance.

I am pretty sure iOS 13.4 (beta and later) did support Coded PHY (Long Range). Tested devices are iPhone SE2 and iPhone 11 Pro. However, it seems iOS 14 removed the support of Coded PHY, accidentally or on purpose, I don't know? The same PHY update request returns "1M PHY" in iOS 14, but "Coded PHY" in iOS 13 (13.4 beta and later). Anyone knows why? Samson

Hi All, I am currently working on a Network Extension App for MacOS using 3 types of extensions provided by Apple's Network Extension Framework. Content Filter, App Proxy (Want to get/capture/log all HTTP/HTTPS traffic), DNS Proxy (Want to get/capture/log all DNS records). Later parse into human readable format. Is my selection of network extension types correct for the intended logs I need? I am able to run with one extension: Main App(Xcode Target1) <-> Content Filter Extension. Here there is a singleton class IPCConnection between App(ViewController.swift) which is working fine with NEMachServiceName from Info.plist of ContentFilter Extension(Xcode Target2) However, when I add an App Proxy extension as a new Xcode Target3, I think the App and extension's communication getting messed up and App not getting started/Crashing. Here, In the same Main App, I am adding new separate IPCConnection for this extension. Here is the project organization/folder structure. MyNetworkExtension ├──MyNetworkExtension(Xcode Target1) │ ├── AppDelegate.swift │ ├── Assets.xcassets │ ├── Info.plist │ ├── MyNetworkExtension.entitlement │ | ── Main │ |-----ViewController.swift │ └── Base.lproj │ └── Main.storyboard ├── ContentFilterExtension(Xcode Target2) │ ├── ContentFilterExtension.entitlement │ │ ├── FilterDataProvider.swift │ │ ├── Info.plist │ │ ├── IPCConnection.swift │ │ └── main.swift ├── AppProxyProviderExtension(Xcode Target3) │ ├── AppProxyProviderExtension.entitlement │ │ ├── AppProxyIPCConnection.swift │ │ ├── AppProxyProvider.swift │ │ ├── Info.plist │ │ └── main.swift └── Frameworks ├── libbsm.tbd └── NetworkExtension.framework Is my Approach for creating a single Network Extension App with Multiple extensions correct or is there any better approach of project organization that will make future modifications/working easier and makes the maintenance better? I want to keep the logic for each extension separate while having the same, single Main App that manages everything(installing, activating, managing identifiers, extensions, etc). What's the best approach to establish a Communication from MainApp to each extension separately, without affecting one another? Is it good idea to establish 3 separate IPC Connections(each is a singleton class) for each extension? Are there any suggestions you can provide that relates to my use case of capturing all the network traffic logs(including HTTP/HTTPS, DNS Records, etc), especially on App to Extension Communication, where my app unable to keep multiple IPC Connections and maintain them separately? I've been working on it for a while, and still unable to make the Network Extension App work with multiple extensions(each as a new Xcode target). Main App with single extension is working fine, but if I add new extension, App getting crashed. I suspect it's due to XPC/IPC connection things! I really appreciate any support on this either directly or by any suggestions/resources that will help me get better understand and make some progress. Please reach out if in case any clarifications or specific information that's needed to better understand my questions. Thank you very much

My company has a server that supports ticket-based TLS session resumption (per RFC 5077). We have done Wireshark captures that show that our iOS client app, which uses URLSession for REST and WebSocket connections to the server, is not sending the TLS "session_ticket" extension in the Client Hello package that necessary to enable ticket-based resumption with the server. Is it expected that URLSession does not support ticket-based TLS session resumption? If "yes", is there any way to tell URLSession to enable ticket-based session resumption? the lower-level API set_protocol_options_set_tls_tickets_enabled() hints that the overall TLS / HTTP stack on IOS does support ticket-based resumption, but I can't see how to use that low-level API with URLSession. I can provide (lots) more technical details if necessary, but hopefully this is enough context to determine whether ticket-based TLS resumption is supported with URLSession. Any tips / clarifications would be greatly appreciated.

Hi, Our project is a MacOS SwiftUI GUI application that bundles a (Sandboxed) System Network Extension, signed with a Developer ID certificate for distribution outside of the app store. The system network extension is used to write a packet tunnel provider (NEPacketTunnelProvider), as our project requires the creation of a TUN device. In order for our System VPN to function, it must reach out to a (self-hosted) server (i.e. to discover a list of peers). Being self-hosted, this server is typically not accessible via the public web, and may only be accessible from within a VPN (such as those also implemented using NEPacketTunnelProvider, e.g. Tailscale, Cloudflare WARP). What we've discovered is that the networking code of the System Network Extension process does not attempt to use the other VPN network interfaces (utunX) on the system. In practice, this means requests to IPs and hostnames that should be routed to those interfaces time out. Identical requests made outside of the Network System Extension process use those interfaces and succeed. The simplest example is where we create a URLSession.downloadTask for a resource on the server. A more complicated example is where we execute a Go .dylib that continues to communicate with that server. Both types of requests time out. Two noteworthy logs appear when packets fail to send, both from the kernel 'process': cfil_hash_entry_log:6088 <CFIL: Error: sosend_reinject() failed>: [30685 com.coder.Coder-Desktop.VPN] <UDP(17) out so b795d11aca7c26bf 57728068503033955 57728068503033955 age 0> lport 3001 fport 3001 laddr 100.108.7.40 faddr 100.112.177.88 hash 58B15863 cfil_service_inject_queue:4472 CFIL: sosend() failed 49 I also wrote some test code that probes using a UDP NWConnection and NWPath availableInterfaces. When run from the GUI App, multiple interfaces are returned, including the one that routes the address, utun5. When ran from within the sysex, only en0 is returned. I understand routing a VPN through another is unconventional, but we unfortunately do need this functionality one way or another. Is there any way to modify which interfaces are exposed to the sysex? Additionally, are these limitations of networking within a Network System Extension documented anywhere? Do you have any ideas why this specific limitation might exist?

In our iOS application, we need to list available WiFi networks so that users can select one for device configuration. Here's the workflow: Initially, the hardware device acts as a WiFi Access Point (AP). The app should scan for nearby WiFi networks to detect the device's AP. The app connects temporarily to this AP and sends the selected WiFi credentials to the device. The device then connects to the selected WiFi network and stops broadcasting its AP. Is this flow achievable on iOS? We understand that Apple restricts access to WiFi scanning APIs — are there any supported methods (e.g., using NEHotspotHelper) or entitlements (such as MFi) that could enable this?

Hi, My app uses the NetworkExtension framework to connect to an access point. For some reason, my app occasionally fails to find and/or connect to my AP (which I know is online and beaconing on a given frequency). This roughly happens 1/10 times. I am using an iPhone 17, running iOS 26.0.1. I am connecting to a WPA2-Personal network. In the iPhone system logs, I see the following: Oct 10 10:34:10 wifid(WiFiPolicy)[54] <Notice>: Dequeuing command type: "Scan" pending commands: 0 Oct 10 10:34:10 wifid(WiFiPolicy)[54] <Notice>: __WiFiDeviceCopyPreparedScanResults: network records count: 0 Oct 10 10:34:10 kernel()[0] <Notice>: wlan0:com.apple.p2p: WiFi infra associated, NAN DISABLED, , DFS state Off, IR INACTIVE, llwLink ACTIVE, RTM-DP 0, allowing scans Oct 10 10:34:10 kernel()[0] <Notice>: wlan0:com.apple.p2p: isScanDisallowedByAwdl[1148] : InfraScanAllowed 1 (RTModeScan 0 NonSteering 0 assistDisc 0 HTMode 0 RTModeNeeded 0 Immin 0 ScanType 1 Flags 0 ScanOn2GOnly 0 DevAllows2G 1) Oct 10 10:34:10 kernel()[0] <Notice>: wlan0:com.apple.p2p: IO80211PeerManager::setScanningState:5756:_scanningState:0x2(oldState 0) on:1, source:ScanManagerFamily, err:0 Oct 10 10:34:10 kernel()[0] <Notice>: wlan0:com.apple.p2p: setScanningState:: Scan request from ScanManagerFamily.

Hi Team, OS is prompting for local network permission for our application which runs as root level daemon. As per the our analysis, it looks like it is prompting from our own library which is trying to get network info ' using /usr/sbin/system_profiler with "-xml -detailLevel basic SPNetworkDataType" and then trying to iterate to find DNS.ServerAddresses for each item. Then using [NSHost hostWithAddress:IPAddress];(When this library is not linked to the app then there is no prompt, so most likely this is the code that is resulting in the prompt). Is this expected ? . Is there any other way that we can get DNS host name without being prompted for local network permission on mac OS 15

I've had a Unreal Engine project that uses libwebsocket to make a websocket connection with SSL to a server. Recently I made a build using Unreal Engine 5.4.4 on MacOS Sequoia 15.5 and XCode 16.4 and for some reason the websocket connection now fails because it can't get the local issuer certificate. It fails to access the root certificate store on my device (Even though, running the project in the Unreal Editor works fine, it's only when making a packaged build with XCode that it breaks) I am not sure why this is suddenly happening now. If I run it in the Unreal editor on my macOS it works fine and connects. But when I make a packaged build which uses XCode to build, it can't get the local issuer certificate. I tried different code signing options, such as sign to run locally or just using sign automatically with a valid team, but I'm not sure if code signing is the cause of this issue or not. This app is only for development and not meant to be published, so that's why I had been using sign to run locally, and that used to work fine but not anymore. Any guidance would be appreciated, also any information on what may have changed that now causes this certificate issue to happen. I know Apple made changes and has made notarizing MacOS apps mandatory, but I'm not sure if that also means a non-notarized app will now no longer have access to the root certificate store of a device, in my research I haven't found anything about that specifically, but I'm wondering if any Apple engineers might know something about this that hasn't been put out publicly.

Hi all, I have a working macOS (Intel) system extension app that currently uses only a Content Filter (NEFilterDataProvider). I need to capture/log HTTP and HTTPS traffic in plain text, and I understand NETransparentProxyProvider is the right extension type for that. For HTTPS I will need TLS inspection / a MITM proxy — I’m new to that and unsure how complex it will be. For DNS data (in plain text), can I use the same extension, or do I need a separate extension type such as NEPacketTunnelProvider, NEFilterPacketProvider, or NEDNSProxyProvider? Current architecture: Two Xcode targets: MainApp and a SystemExtension target. The SystemExtension target contains multiple network extension types. MainApp ↔ SystemExtension communicate via a bidirectional NSXPC connection. I can already enable two extensions (Content Filter and TransparentProxy). With the NETransparentProxy, I still need to implement HTTPS capture. Questions I’d appreciate help with: Can NETransparentProxy capture the DNS fields I need (dns_hostname, dns_query_type, dns_response_code, dns_answer_number, etc.), or do I need an additional extension type to capture DNS in plain text? If a separate extension is required, is it possible or problematic to include that extension type (Packet Tunnel / DNS Proxy / etc.) in the same SystemExtension Xcode target as the TransparentProxy? Any recommended resources or guidance on TLS inspection / MITM proxy setup for capturing HTTPS logs? There are multiple DNS transport types — am I correct that capturing DNS over UDP (port 53) is not necessarily sufficient? Which DNS types should I plan to handle? I’ve read that TransparentProxy and other extension types (e.g., Packet Tunnel) cannot coexist in the same Xcode target. Is that true? Best approach for delivering logs from multiple extensions to the main app (is it feasible)? Or what’s the best way to capture logs so an external/independent process (or C/C++ daemon) can consume them? Required data to capture (not limited to): All HTTP/HTTPS (request, body, URL, response, etc.) DNS fields: dns_hostname, dns_query_type, dns_response_code, dns_answer_number, and other DNS data — all in plain text. I’ve read various resources but remain unclear which extension(s) to use and whether multiple extension types can be combined in one Xcode target. Please ask if you need more details. Thank you.

Howdy, I've been developing a packet tunnel extension meant to run on iOS and MacOS. For development I'm using xcodegen + xcodebuild to assemble a bunch of swift and rust code together. I'm moving from direct TUN device management on Mac to shipping a Network Extension (appex). With that move I noticed that on some mac laptops NE fails to start completely, whilst on others everything works fine. I'm using CODE_SIGN_STYLE: Automatic, Apple IDs are within the same team, all devices are registered as dev devices. Signing dev certificates, managed by xcode. Some suspicious logs: (NetworkExtension) [com.apple.networkextension:] Signature check failed: code failed to satisfy specified code requirement(s) ... (NetworkExtension) [com.apple.networkextension:] Provider is not signed with a Developer ID certificate What could be the issue? Where those inconsistencies across devices might come from?

Recently, my application was having trouble sending udp messages after it was reinstalled. The cause of the problem was initially that I did not grant local network permissions when I reinstalled, I was aware of the problem, so udp worked fine after I granted permissions. However, the next time I repeat the previous operation, I also do not grant local network permissions, and then turn it back on in the Settings, and udp does not work properly (no messages can be sent, the system version and code have not changed). Fortunately, udp worked after rebooting the phone, and more importantly, I was able to repeat the problem many times. So I want to know if the process between when I re-uninstall the app and deny local network permissions, and when I turn it back on in Settings, is that permissions have been granted normally, and not fake, and not required a reboot to reset something for udp to take effect. I'm not sure if it's the system, or if it's a similar situation as described here, hopefully that will help me find out

I have a custom VPN app that uses NETunnelProviderManager to install a VPN Profile if one is not already installed. On previous iOS versions this would open the VPN Settings and ask for either the PIN, FaceID or TouchID and install the profile. With iOS 26 beta5 it opens the VPN Settings and stops. Is this a bug in iOS 26? Have there been changes to NETunnelProviderManager for iOS 26 that I'm not aware of? FYI we do the samething on macOS 26 beta5 and that works as expected.

Eager to see the Wi-Fi Aware communication between iPhone (iOS 26) and an Android device, I tried iOS 26 beta on my iPhone16. and tried below code snippet from provided example at https://developer.apple.com/documentation/wifiaware/building-peer-to-peer-apps. Idea is to first verify discovery of Android WiFiAware service on iOS. extension WAPublishableService { public static var simulationService: WAPublishableService { allServices[simulationServiceName]! } } extension WASubscribableService { public static var simulationService: WASubscribableService { allServices[simulationServiceName]! } } struct ContentView: View { @State private var showingDevicePicker = false @State private var pairedDevices: [WAPairedDevice] = [] // To hold discovered/paired devices var body: some View { VStack { Button("Discover Devices") { showingDevicePicker = true // Trigger the device picker presentation } .sheet(isPresented: $showingDevicePicker) { DevicePicker(.wifiAware(.connecting(to: .selected([]), from: .simulationService))) { endpoint in print("Paired Endpoint: \(endpoint)") } label: { Image(systemName: "plus") Text("Add Device") } fallback: { Image(systemName: "xmark.circle") Text("Unavailable") } } List(pairedDevices) { device in Text(device.name ?? "Unknown Device") } } } } With suggested entitlement of WiFiAware and info.plist of service info. Then I had Android device with WIFiAware service publishing service (service name set '_sat-simulation._udp') from this app https://github.com/anagramrice/NAN. But above iOS app is unable to find the service published from android device. Am I missing something? Note: the above Android-NAN app seems to be working fine between Android to Another Android.

We've received several reports of a new bug while setting up our products with WAC. The Accessory Setup UI appears with a blank network selected and the message 'This accessory will be set up to join "(null)".' at top. The user can tap "Show Other Networks..." to select another network, but this experience is very confusing. Why does this UI present a choice that is known to be invalid when other valid choices exist? I've captured a screenshot and sysdiagnose from this case. In most cases this problem happens only intermittently, but I can reproduce it consistently by disconnecting my iPhone from any WiFi network (WiFi remains enabled). My suggestion for a better user experience is that this UI should select the default network according to these rules: The network to which iPhone is currently connected. Any network which is in the known/my list for this iPhone Any valid network I believe rule #1 is the existing behavior, but applying rules #2 and #3 as fallbacks would be an improvement. Is there anything I can change in my iOS code or in my accessory's WAC server to improve this experience?
