Could anyone teach me how to ask iOS 18 to have a prompt during set-up process of a new APP if user accidentally turns off Local Network ?

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?

When filtering traffic to localhost (127.0.0.1), it causes Maven repository synchronization to fail in IntelliJ IDEA. However, Maven works correctly when local traffic is not filtered. I will provide a minimal code reproduction below. - (void)startFilterWithCompletionHandler:(void (^)(NSError *error))completionHandler { // Add code to initialize the filter NSMutableArray *rules = [NSMutableArray array]; NENetworkRule * rule = [[NENetworkRule alloc] initWithRemoteNetwork:nil remotePrefix:0 localNetwork:nil localPrefix:0 protocol:NENetworkRuleProtocolTCP direction:NETrafficDirectionAny]; [rules addObject:[[NEFilterRule alloc]initWithNetworkRule:rule action:NEFilterActionFilterData]]; rule = [[NENetworkRule alloc] initWithRemoteNetwork:nil remotePrefix:0 localNetwork:nil localPrefix:0 protocol:NENetworkRuleProtocolUDP direction:NETrafficDirectionAny]; [rules addObject:[[NEFilterRule alloc]initWithNetworkRule:rule action:NEFilterActionFilterData]]; NWHostEndpoint *hostEndpointIpv4 = [NWHostEndpoint endpointWithHostname:@"127.0.0.1" port:@"0"]; NENetworkRule *localHostRuleIpv4 = [[NENetworkRule alloc] initWithRemoteNetwork:hostEndpointIpv4 remotePrefix:32 localNetwork:hostEndpointIpv4 localPrefix:32 protocol:NENetworkRuleProtocolAny direction:NETrafficDirectionAny]; [rules addObject:[[NEFilterRule alloc]initWithNetworkRule:localHostRuleIpv4 action:NEFilterActionFilterData]]; NEFilterSettings *filterSetting = [[NEFilterSettings alloc] initWithRules:rules defaultAction:NEFilterActionAllow]; [self applySettings:filterSetting completionHandler:^(NSError * _Nullable error) { if (error) { NSLog(@"Failed to apply filter settring: %@", error.localizedDescription); } completionHandler(error); }]; } Maven Sync error: System Log: 默认 17:35:13.184509+0800 kernel cfil_inp_log:6179 <CFIL: outbound TCP data dropped for pre-existing un-filtered flow>: [41046 idea] <TCP out so 3bb6402f58a82e37 - flags 0x800840 0x80> lport 63166 fport 29735 laddr 127.0.0.1 faddr 127.0.0.1 默认 17:35:13.184510+0800 kernel cfil_inp_log:6179 <CFIL: outbound TCP data dropped for pre-existing un-filtered flow>: [41046 idea] <TCP out so d6dde374c8cb613b - flags 0x800840 0x80> lport 63165 fport 29735 laddr 127.0.0.1 faddr 127.0.0.1 默认 17:35:13.529546+0800 kernel cfil_inp_log:6179 <CFIL: outbound TCP data dropped for pre-existing un-filtered flow>: [41046 idea] <TCP out so cc915e74ba29f8cb - flags 0x800840 0x80> lport 63169 fport 39066 laddr 127.0.0.1 faddr 127.0.0.1 默认 17:35:13.529546+0800 kernel cfil_inp_log:6179 <CFIL: outbound TCP data dropped for pre-existing un-filtered flow>: [41046 idea] <TCP out so 2e15c3e54ebcc45 - flags 0x800840 0x80> lport 63168 fport 39066 laddr 127.0.0.1 faddr 127.0.0.1 默认 17:35:14.046094+0800 kernel cfil_inp_log:6179 <CFIL: outbound TCP data dropped for pre-existing un-filtered flow>: [41046 idea] <TCP out so 71f6d3a53472131f - flags 0x800840 0x80> lport 63172 fport 53241 laddr 127.0.0.1 faddr 127.0.0.1 默认 17:35:14.046145+0800 kernel cfil_inp_log:6179 <CFIL: outbound TCP data dropped for pre-existing un-filtered flow>: [41046 idea] <TCP out so c88a367c9717185b - flags 0x800840 0x80> lport 63171 fport 53241 laddr 127.0.0.1 faddr 127.0.0.1 Environment Details: Operating System: macOS 15.5 (Sequoia) IDE: IntelliJ IDEA 2025.1 Relevant Technology: NEFilterDataProvider (Network Extension) I have found reports of similar problems online： https://discussionschinese.apple.com/thread/255270330?sortBy=rank https://blog.csdn.net/weixin_42339552/article/details/137402307 They all seem to be caused by network extension。

On "Accessory Interface Specification CarPlay Addendum R10", it says that it is recommended that the accessory uses a MIMO (2x2) hardware configuration, does this imply that WiFi 5 and SISO (1X1) will be phased out in the near future? When will WiFi 6 MIMO (2x2) become mandatory? On "Accessory Interface Specification CarPlay Addendum R10", it says that Spatial Audio is mandatory. However, for aftermarket in-vehicle infotainment (IVI) system due to the number of speakers are less than 6, is it allowed not to support spatial audio for this type of aftermarket IVI system?

Hi, I'm developing a security-focused iOS application and would like to detect potentially suspicious rogue access points. Specifically, I need to access the BSSID of the currently connected Wi-Fi network to analyze and identify inconsistencies (e.g. multiple APs using the same SSID). I understand that access to certain network information is restricted on iOS. Is it possible to use the Network Extension framework (or any approved API) to retrieve the BSSID? If so, are there any specific entitlements or usage descriptions required to ensure App Store approval? My goal is to implement this functionality in full compliance with App Store Review Guidelines and user privacy policies.

I'm working on enabling a content filter in my iOS app using NEFilterManager and NEFilterProviderConfiguration. The setup works perfectly in debug builds when running via Xcode, but fails on TestFlight builds with the following error: **Failed to save filter settings: permission denied ** **Here is my current implementation: ** (void)startContentFilter { NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; [userDefaults synchronize]; [[NEFilterManager sharedManager] loadFromPreferencesWithCompletionHandler:^(NSError * _Nullable error) { dispatch_async(dispatch_get_main_queue(), ^{ if (error) { NSLog(@"Failed to load filter: %@", error.localizedDescription); [self showAlertWithTitle:@"Error" message:[NSString stringWithFormat:@"Failed to load content filter: %@", error.localizedDescription]]; return; } NEFilterProviderConfiguration *filterConfig = [[NEFilterProviderConfiguration alloc] init]; filterConfig.filterSockets = YES; filterConfig.filterBrowsers = YES; NEFilterManager *manager = [NEFilterManager sharedManager]; manager.providerConfiguration = filterConfig; manager.enabled = YES; [manager saveToPreferencesWithCompletionHandler:^(NSError * _Nullable error) { dispatch_async(dispatch_get_main_queue(), ^{ if (error) { NSLog(@"Failed to save filter settings: %@", error.localizedDescription); [self showAlertWithTitle:@"Error" message:[NSString stringWithFormat:@"Failed to save filter settings: %@", error.localizedDescription]]; } else { NSLog(@"Content filter enabled successfully!"); [self showAlertWithTitle:@"Success" message:@"Content filter enabled successfully!"]; } }); }]; }); }]; } **What I've tried: ** Ensured the com.apple.developer.networking.networkextension entitlement is set in both the app and system extension. The Network extension target includes content-filter-provider. Tested only on physical devices. App works in development build, but not from TestFlight. **My questions: ** Why does saveToPreferencesWithCompletionHandler fail with “permission denied” on TestFlight? Are there special entitlements required for using NEFilterManager in production/TestFlight builds? Is MDM (Mobile Device Management) required to deploy apps using content filters? Has anyone successfully implemented NEFilterProviderConfiguration in production, and if so, how?

Hi there, I'm having an issue hoping someone could help. We have an iOS app that uses CoreBluetooth to connect to peripherals using the central manager. The app works great - However, when using the same exact central manager for our watchos app, it will attempt to connect, but I never get a callback for either didConnect or didFailToConnect. The watch can connect successfully to other BLE devices, so the watch itself is capable of BLE connectivity. Here's a list of thing's I've tried (unsuccessfully): 1) Added every bluetooth-related entitlement to info.plist Privacy - Bluetooth Always Usage Description Privacy - Bluetooth Peripheral Usage Description Background Modes: App communicates using CoreBluetooth, App shares data using CoreBluetooth 2) Checked for Single-Connection Limits Verified that the iPhone was fully disconnected from the peripheral to ensure the device wasn’t limited to one connection. Attempted to connect on watchOS alone (with iPhone turned off) 3) Tried various options for CBCentralManager, scanForPeripherals, and connect I went through all the keys for various options and tried just setting them, they had no effect CBCentralManagerOptionShowPowerAlertKey, CBConnectPeripheralOptionEnableTransportBridgingKey Item 2 4) Tried .registerForConnectionEvents() 5) Set peripheral's delegate to the central in the didDiscover, stored it in a variable to ensure a strong reference to it I get no warnings either. The last time I ran into something like this, I found out the watchOS blocks TCP sockets. If I print out the CBPeripheralState a few seconds after trying to connect, it shows its stuck on CBPeripheralStateConnecting. Any advice or direction is greatly appreciated Below is the code and various print outs (day 2 into debugging, so it's not pretty) class WatchBLEManager:NSObject,CBCentralManagerDelegate, ObservableObject{ var centralManager: CBCentralManager? @Published var devices : [String:AtomBLEDevice] = [:] private var scanningDevice:AtomBLEDevice? var bleStatus:WatchBLEStatus = .blePoweredOff func startBLE() { centralManager = CBCentralManager(delegate: self, queue: nil,options: [CBCentralManagerOptionShowPowerAlertKey: true]) self.centralManager?.delegate = self } func startScan() { self.centralManager?.scanForPeripherals(withServices: [],options: [CBCentralManagerScanOptionAllowDuplicatesKey : true]) self.centralManager?.delegate = self } func stopScan() { print("stopping scan") self.centralManager?.stopScan() filterName = "" scanningDevice = nil } func centralManagerDidUpdateState(_ central: CBCentralManager) { switch (central.state) { //... other states omitted case .poweredOff: bleStatus = .blePoweredOff // bleStateDelegate?.didBlePoweredOff() for device in devices.values{ device.isConnected = false } print("BLE is Powered Off") case .poweredOn: bleStatus = .blePoweredOn // bleStateDelegate?.didBlePoweredOn() startScan() centralManager?.registerForConnectionEvents() print("Central supports extended scan and connect: ", CBCentralManager.supports(.extendedScanAndConnect)) print("powered on") @unknown default: print("BLE is Unknown") } } private let connectionQueue = DispatchQueue(label: "com.atom.connectionQueue") var connectingTo: String? = nil var peripheral: CBPeripheral? = nil func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) { guard let localName = advertisementData[CBAdvertisementDataLocalNameKey] as?

Hi everyone, I'm developing a visionOS app that allows users to download large video files (similar to a movie download experience, with each file being around 10 GB). I've successfully implemented the core video download functionality using URLSession, and everything works as expected while the app is active. Now, I’m looking to support background downloading. Specifically, I want users to be able to start a download and then leave the app (e.g., switch apps or return to the home screen) while the download continues in the background. Additionally, I’d like to confirm a specific scenario: If the user starts a download, then removes the headset (keeping the device turned on and connected to power), will the download continue in the background? Or does visionOS suspend the app or downloads in this case? I’m considering using a background URLSessionConfiguration (as done in iOS/macOS) to enable this behavior, but I’m not sure if it behaves the same way on visionOS or if there are special limitations or best practices when handling large downloads on this platform. Any insights or official guidance would be greatly appreciated! Thanks!

We are a Layer 3 VPN provider offering a comprehensive SASE (Secure Access Service Edge) solution that includes TLS inspection, threat protection, granular access control, and secure access to private resources. One of the key challenges we face involves TLS inspection. Many mobile applications, especially on iOS, implement certificate pinning, which causes them to fail when TLS inspection is applied. These apps expect connections to be secured with a specific certificate or trusted certificate authority, and inspection disrupts this trust model. On iOS, the current limitation is that the Packet Tunnel Provider extension does not provide visibility into the originating application (i.e., there is no API to obtain the app’s bundle ID or package name associated with a given network connection). Due to this, we are unable to dynamically determine whether TLS inspection should be bypassed for a particular app. While Apple’s Per-App VPN is one possible solution, it introduces a significant drawback: any applications that are excluded from the VPN configuration are entirely outside the VPN tunnel. This means they do not benefit from any of our SASE features — including secure access to internal resources, DNS/web content filtering, or threat detection. This limits the effectiveness of our solution in environments where both inspection and secure access are critical. We would like to understand whether iOS has any current or planned capabilities to associate a network flow (e.g., a 5-tuple: source IP, destination IP, source port, destination port, and protocol) with the originating app. Such a capability would allow us to programmatically identify certificate-pinned apps and selectively disable TLS inspection without excluding them entirely from the VPN, thereby preserving the full set of SASE protections. Is there any guidance or roadmap update from Apple that addresses this use case?

We’re looking to implement a custom IPSec IKEv2 VPN using the Packet Tunnel Provider network extension on iOS because we need to add extra information to EAP, which the built-in IKEv2 VPN configuration does not support. Is it possible to handle the full IKEv2 negotiation and IPSec tunneling within the Packet Tunnel Provider extension? Or are there limitations that would prevent implementing a full IKEv2 stack this way? Any insights or alternative approaches would be appreciated. Thanks!

I’m developing an app designed for hospital environments, where public internet access may not be available. The app includes two components: the main app and a Local Connectivity Extension. Both rely on persistent TCP socket connections to communicate with a local server. We’re observing a recurring issue where the extension’s socket becomes unresponsive every 1–3 hours, but only when the device is on the lock screen, even if the main app remains in the foreground. When the screen is not locked, the connection is stable and no disconnections occur. ❗ Issue Details: • What’s going on: The extension sends a keep-alive ping packet every second, and the server replies with a pong and a system time packet. • The bug: The server stops receiving keep alive packets from the extension.  • On the server, we detect about 30 second gap on the server, a gap that shows no packets were received by the extension. This was confirmed via server logs and Wireshark).  • On the extension, from our logs there was no gap in sending packets. From it’s perspective, all packets were sent with no error.  • Because no packet are being received by the server, no packets will be sent to the extension. Eventually the server closes the connection due to keep-alive timeout.  • FYI we log when the NEAppPushProvider subclass sleeps and it did NOT go to sleep while we were debugging. 🧾 Example Logs: Extension log: 2025-03-24 18:34:48.808 sendKeepAliveRequest() 2025-03-24 18:34:49.717 sendKeepAliveRequest() 2025-03-24 18:34:50.692 sendKeepAliveRequest() ... // continuous sending of the ping packet to the server, no problems here 2025-03-24 18:35:55.063 sendKeepAliveRequest() 2025-03-24 18:35:55.063 keepAliveTimer IS TIME OUT... in CoreService. // this is triggered because we did not receive any packets from the server 2025-03-24 18:34:16.298 No keep-alive received for 16 seconds... connection ID=95b3... // this shows that there has been no packets being received by the extension ... 2025-03-24 18:34:30.298 Connection timed out on keep-alive. connection ID=95b3... // eventually closes due to no packets being received 2025-03-24 18:34:30.298 Remote Subsystem Disconnected {name=iPhone|Replica-Ext|...} ✅ Observations: • The extension process continues running and logging keep-alive attempts. • However, network traffic stops reaching the server, and no inbound packets are received by the extension. • It looks like the socket becomes silently suspended or frozen, without being properly closed or throwing an error. ❓Questions: • Do you know why this might happen within a Local Connectivity Extension, especially under foreground conditions and locked ? • Is there any known system behavior that might cause the socket to be suspended or blocked in this way after running for a few hours? Any insights or recommendations would be greatly appreciated. Thank you!

I am trying to intercept localhost connections within NETransparentProxyProvider system extension. As per NENetworkRule documentation If the address is a wildcard address (0.0.0.0 or ::) then the rule will match all destinations except for loopback (127.0.0.1 or ::1). To match loopback traffic set the address to the loopback address. I tried to add NWHostEndpoint *localhostv4 = [NWHostEndpoint endpointWithHostname:@"127.0.0.1" port:@""]; NENetworkRule *localhostv4Rule = [[NENetworkRule alloc] initWithDestinationNetwork:localhostv4 prefix:32 protocol:NENetworkRuleProtocolAny]; in the include network rules. I tried several variations of this rule like port 0, prefix 0 and some others. But the provider disregards the rule and the never receives any traffic going to localhost on any port. Is there any other configuration required to receive localhost traffic in NETransparentProxyProvider?

I am working on watch os project. I need to check network connectivity when user turn on and off the network. I am using NWPathMonitor for check network availability. I am connected with wifi but it still showing unsatisfied not real device but it's working perfect on simulator.

Hi I am developing the packet tunnel extension on a SIP enabled device. If I build the app and notarize and install it on the device, it works fine. If I modify, build and execute the App (which contains the system extension), it fails with below error. 102.3.1.4 is production build. And 201.202.0.101 is for XCode build. SystemExtension "&lt;&lt;complete name&gt;&gt;.pkttunnel" request for replacement from 102.3.1.4 to 201.202.0.101 Packet Tunnel SystemExtension "&lt;&lt;complete name&gt;&gt;.pkttunnel" activation request did fail: Error Domain=OSSystemExtensionErrorDomain Code=8 "(null)" If SIP is disabled, it works fine. Is there a way the system extension can be developed even if SIP remains enabled?

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?

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 am learning about layer 3 VPN implementations for MacOS, and am slowly making my way through docs and tutorials. I noticed that part of creating an instance of NETunnelProviderManager on the app side of the project requires the specification of protocolConfiguration via an instance of NETunnelProviderProtocol. One of the arguments for this class is serverAdress, which to my understanding, tells the OS where to route traffic towards at the end of the day. My question: many VPNs these days allow the option to specify the location for which you want your traffic to be routed through. I imagine this would necessitate changing this serverAddress field in the backend. However, setting this option (on a commercially available VPN) doesn't typically prompt the OS notification that you get when initially installing a VPN configuration for the first time. How is this functionality achieved? I could see one possible solution being that most VPN providers route through a main service beforehand (so the first IP in the chain never has to change), though I could see this being problematic for a number of other reasons. Assuming you have a valid NETunnelProviderManager object called manager, is this valid? self.manager?.protocolConfiguration?.serverAddress = "somewhereElse" Even if it compiles, will the traffic be properly re-routed? My understanding of the flow right now is that in order to "lock in" a new configuration, or modify it, you need to call manager.saveToPreferences, which triggers the OS notification I mentioned earlier.

I'm running a Node.js server on my MacBook with Apple M4 Pro chip, macOS Sequoia 15.4, and Node.js v23.10.0. The server starts normally on port 5000 and logs show that it's listening correctly. However, when I try to access it via browser or Postman (http://localhost:5000/api/...), I get a 403 Forbidden error. After checking with lsof -i :5000, I noticed that the ControlCenter process is listening on port 5000 under the name commplex-main. Interestingly, this doesn't happen on M3 Pro machines. On those devices, Node.js runs fine on port 5000 and can be accessed from Postman and browsers. Is port 5000 now internally reserved by macOS or used by some system-level service in Sequoia or Apple Silicon (M4 Pro)? Should I avoid using this port going forward? Any official clarification would be appreciated.
