Hello. I'd like to report something different behavior with before. In previous versions of iOS (16.1~), after completing Apple Home app → SmartThings iOS app Multi Fabric onboarding, there was only one iOS system fabric in the device's fabric list as shown below. Apple Home app Apple Keychain (iOS system fabric commissioned by the Apple Home app or SmartThings iOS app) SmartThings In iOS 16.6.1, after completing Apple Home app → ST iOS app Multi Fabric onboarding, the device's fabric list has been changed to include two iOS system fabrics as shown below. Apple Home app Apple Keychain (iOS system fabric commissioned by the Apple Home app) Apple Keychain (iOS system fabric commissioned by the SmartThings iOS app) SmartThings At this time, if the user removes the device from the SmartThings iOS app, only SmartThings fabric (4) will be deleted and Apple Keychain (3) will remain. Apple Home app Apple Keychain (iOS system fabric commissioned by the Apple Home app) Apple Keychain (iOS system fabric commissioned by the SmartThings iOS app) I'm afraid that it will fail if I try to add my device to Google Home or Alexa. Because max fabric count is 5 and it counts Apple keychain also. Is this behavior expected? Thanks.

Hello, I think that I found a bug with NWBrowser and I'd like to ask you can fix this. Problem NWBrowser does not return the result to the app, while NetServiceBrowser returns. Problem occurs when using only Meross device, in other Matter device cases, both api works fine. Actually I want to get TXT Record from Meross, but failed with NWBrowser Steps Add Meross plug device (Matter, Wi-Fi device) to Apple Home app Turn On Pairing Mode of Meross device When I try to discover it with NWBrowser > it is NOT discovered (with NetServiceBrowser > it is discovered) Results When I use NWBrowser, I can't get any result from the handler. On the other hand, with NetServiceBrowser, I can get a result. When I capture the packets with WireShark, the packets are same on both cases Case1: with NWBrowser Case2: with NetServiceBrowser With same packets, Case1 does not return any result and Case2 returns results. I'm trying to attaching the WireShark capture file and iOS console logs, but it continuosly fails. Please let me know how I can send them. Code Her is my code. NWBrowser let bonjourWithTXT = NWBrowser.Descriptor.bonjourWithTXTRecord(type: "_matterc._udp.", domain: "local.") let params = NWParameters.init() self.nwBrowser = NWBrowser(for: bonjourWithTXT, using: params) self.nwBrowser?.browseResultsChangedHandler = { [weak self] results, changes in // Can not get any results here // } self.nwBrowser?.start(queue: .main) NetServiceBrowser self.bonjourBrowser = NetServiceBrowser() self.bonjourBrowser?.delegate = self self.bonjourBrowser?.searchForServices(ofType: "_matterc._udp.", inDomain: "local.") func netServiceBrowser(_ browser: NetServiceBrowser, didFind service: NetService, moreComing: Bool) { service.delegate = self service.resolve(withTimeout: resolutionTimeout) netService.insert(service) } func netServiceBrowser(_ browser: NetServiceBrowser, didRemove service: NetService, moreComing: Bool) { netServices.remove(service) } func netServiceDidResolveAddress(_ service: NetService) { // I can get found services here // }

Hi, I wanted to use MatterAddDeviceRequest api in MatterSupport. When I called api, system pop-up shows up and then right after tapping 'Add to @' button, pop-up always shows HMErrorDomain 76 error. I found this code in HomeKit.HMError case keychainSyncNotEnabled = 76 I wonder that enabling keychain sync is mandatory to use MatterAddDeviceRequest api? Or could you tell me why this error always occurs? Thanks!

Hi, I wanted to try using the new NWBrowser available in iOS 13 to replace my old Bonjour browsing code(NetServiceBrowser), problem is I'm unabe to get all IPv6 Addresses(except link local address) of the service I'm looking for. In my environment, when I checked with ifconfig command, there are three IPv6 addresses. fe80::c092:a0ff:fe51:3c8 fd1c:efcd:7e66:0:c092:a0ff:fe51:3c8 fd1c:efcd:7e66:0:68d:6b27:81e2:7511 Using NWBrowser and NWConnection, I ended up getting #1 address but I couldn't get #2, #3 addresses. Here is my code. let bonjour = NWBrowser.Descriptor.bonjourWithTXTRecord(type: serviceType, domain: searchDomain) let params = NWParameters.init() self.nwBrowser = NWBrowser(for: bonjour, using: params) self.nwBrowser?.browseResultsChangedHandler = { [weak self] results, changes in guard let self = self else { return } for change in changes { if case .added(let result) = change { let connection = NWConnection(to: result.endpoint, using: .udp) connection.stateUpdateHandler = { [weak self] state in switch state { case .ready: if let remoteEndpoint= connection.currentPath?.remoteEndpoint, case .hostPort(let host, let port) = innerEndpoint { // here I can get #1 address from host // but, I couldn't get #2, #3 addresses } } } connection.start(queue: .main) } } } self.nwBrowser?.start(queue: .main) Using NetServiceBrowser and netServiceDidResolveAddress(), I can get All IP addresses(#1, #2, #3) Here is my code. let netServiceBrowser = NetServiceBrowser() netServiceBrowser.delegate = self netServiceBrowser.searchForServices(ofType: serviceType, inDomain: searchDomain) func netServiceBrowser(_ browser: NetServiceBrowser, didFind service: NetService, moreComing: Bool) { service.delegate = self service.resolve(withTimeout: resolutionTimeoutSeconds) } func netServiceDidResolveAddress(_ service: NetService) { // service.addresses is [Data], I can get all addresses I want. } I wonder if getting only Link Local Address through NWConnection is the intended behavior. Or is there a way to get all address using NWBrowser and NWConnection?
