Hello everyone, I'm developing a macOS application with an integrated Content Filter System Extension. Both the main app and the extension are signed with a Developer ID Application provisioning profile. When building in Xcode, I'm encountering an entitlement mismatch error. I've inspected the provisioning profile using the command: security cms -D -i FilterContentExtension-prod-profile.provisionprofile | grep -A 10 com.apple.developer.networking.networkextension And found that the com.apple.developer.networking.networkextension section only contains values with the -systemextension suffix, for example: content-filter-provider-systemextension. However, when I enable Network Extension → Content Filter in Xcode, the .entitlements file is generated with: content-filter-provider. This leads to the error: "Provisioning profile 'FilterContentExtension-prod-profile' doesn't match the entitlements file’s value for the com.apple.developer.networking.networkextension entitlement." My specific questions are: Why does this error occur? How can I use the content-filter-provider entitlement? If I want to use the content-filter-provider entitlement inside com.apple.developer.networking.networkextension for my Content Filter System Extension, what should I do?

We are developing an iOS application that is interacting with HTTP APIs that requires us to put a unique UUID (a nonce) as an header on every request (obviously there's more than that, but that's irrilevant to the question here). If the same nonce is sent on two subsequent requests the server returns a 412 error. We should avoid generating this kind of errors as, if repeated, they may be flagged as a malicious activity by the HTTP APIs. We are using URLSession.shared.dataTaskPublisher(for: request) to call the HTTP APIs with request being generated with the unique nonce as an header. On our field tests we are seeing a few cases of the same HTTP request (same nonce) being repeated a few seconds on after the other. Our code has some retry logic only on 401 errors, but that involves a token refresh, and this is not what we are seeing from logs. We were able to replicate this behaviour on our own device using Network Link Conditioner with very bad performance, with XCode's Network inspector attached we can be certain that two HTTP requests with identical headers are actually made automatically, the first request has an "End Reason" of "Retry", the second is "Success" with Status 412. Our questions are: can we disable this behaviour? can we provide a new request for the retry (so that we can update headers)? Thanks, Francesco

Hi everyone, I’m encountering what appears to be a system-level issue with NEAppPushProvider extensions being unable to communicate with other devices on the local network, even when the main app has already been granted Local Network permission by the user. Context The following problem occurs in an iPad app running iOS 18.5. The main app successfully requests and is granted Local Network access via NSLocalNetworkUsageDescription in its Info.plist configuration. It can connect to a WebSocket server hosted on the local network without any issues, resolving its address by name. The extension (NEAppPushProvider) uses the same networking code as the app, extended via target membership of a controller class. It attempts to connect to the same hostname and port but consistently fails to establish a connection. The system log shows it properly resolving DNS but being stopped due to "local network prohibited". An extract of the logs from the Unified Logging System: 12:34:10.086064+0200 PushProvider [C526 Hostname#fd7b1452:8443 initial parent-flow ((null))] event: path:start @0.000s 12:34:10.087363+0200 PushProvider [C526 Hostname#fd7b1452:8443 waiting parent-flow (satisfied (Path is satisfied), interface: en0[802.11], ipv4, dns, uses wifi)] event: path:satisfied @0.005s 12:34:10.090074+0200 PushProvider [C526 Hostname#fd7b1452:8443 in_progress parent-flow (satisfied (Path is satisfied), interface: en0[802.11], ipv4, dns, uses wifi)] event: flow:start_connect @0.006s 12:34:10.093190+0200 PushProvider [C526.1 Hostname#fd7b1452:8443 in_progress resolver (satisfied (Path is satisfied), interface: en0[802.11], ipv4, dns, uses wifi)] event: resolver:start_dns @0.009s 12:34:10.094403+0200 PushProvider [C526.1.1 IPv4#f261a0dc:8443 waiting path (unsatisfied (Local network prohibited), interface: en0[802.11], ipv4, uses wifi)] event: path:unsatisfied @0.010s 12:34:10.098370+0200 PushProvider [C526.1.1.1 IPv4#f261a0dc:8443 failed path (unsatisfied (Local network prohibited), interface: en0[802.11], ipv4, uses wifi)] event: null:null @0.014s 12:34:10.098716+0200 PushProvider [C526.1 Hostname#fd7b1452:8443 failed resolver (satisfied (Path is satisfied), interface: en0[802.11], ipv4, dns, uses wifi)] event: resolver:children_failed @0.015s 12:34:10.099297+0200 PushProvider [C526 Hostname#fd7b1452:8443 waiting parent-flow (satisfied (Path is satisfied), interface: en0[802.11], ipv4, dns, uses wifi)] event: flow:child_failed @0.016s What I’ve Confirmed: The extension works perfectly if the DNS is changed to resolve the name to a public IP instead of a local one. The extension always connects by hostname. Devices on the local network can resolve each other’s IP addresses correctly and respond to pings. What I’ve Tried Adding NSLocalNetworkUsageDescription to the main app’s Info.plist, as recommended. Clean building the project again. Removing and reinstalling the app to ensure permission prompts are triggered fresh. Restarting the iPad. Ensuring main app cannot access the local network until the permission is granted. Ensuring the main app has connected to the same hostname and port before the extension attempts a connection Toggling the permission manually in Settings. Apple’s documentation states (TN3179): “In general, app extensions share the Local Network privilege state of their container app.” It also notes that some background-running extension types may be denied access if the privilege is undetermined. But in my case, the main app clearly has Local Network access, and the extension never receives it, even after repeated successful connections by the main app. Question Is this a known limitation with NEAppPushProvider? Is there a recommended way to ensure the extension is able to use the local network permission once the user has granted it on the app? Any feedback, suggestions, or confirmation would be greatly appreciated. Thanks in advance.

Is it possible to capture or inspect UDP traffic using iOS content filter APIs (e.g., NEFilterDataProvider)? If not, what are the current technical or policy limitations that prevent UDP inspection via these frameworks? Any insights or suggestions on these topics would be highly appreciated.

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

I'm working on a project that says it's to be based on the QNE2TransparentProxyMac sample code but don't have the original sample code. Can I get a pointer to the sample code and documentation please? Google search didn't find it for some reason. Thanks! Peter

Hi everyone, I'm trying to establish a connection to a server that requires mutual TLS (mTLS) using NSURLSession in an iOS app. The server is configured with a self-signed root CA (in the project, we are using ca.cer) and requires clients to present a valid certificate during the TLS handshake. What I’ve done so far: Server trust is working: I manually trust the custom root CA using SecTrustSetAnchorCertificates and SecTrustEvaluateWithError. I also configured the necessary NSAppTransportSecurity exception in Info.plist to allow the server certificate to pass ATS. This is confirmed by logs showing: Server trust succeeded The .p12 identity is correctly created: Contains the client certificate and private key. Loaded using SecPKCS12Import with the correct password. I implemented the delegate method: func urlSession(_ session: URLSession, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) { if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust { // Server trust override code (working) ... } if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodClientCertificate { print("🔐 Client cert challenge triggered") if let identity = loadIdentity() { let credential = URLCredential(identity: identity, certificates: nil, persistence: .forSession) completionHandler(.useCredential, credential) } else { completionHandler(.cancelAuthenticationChallenge, nil) } return } completionHandler(.performDefaultHandling, nil) } The session is correctly created using my custom delegate: let delegate = MTLSDelegate(identity: identity, certificates: certs) let session = URLSession(configuration: .default, delegate: delegate, delegateQueue: nil) Despite everything above, the client certificate is never sent, and the request fails with: Error Domain=NSURLErrorDomain Code=-1206 "The server requires a client certificate." From logs, it's clear the delegate is being hit for NSURLAuthenticationMethodServerTrust, but not for NSURLAuthenticationMethodClientCertificate.

Hello everyone, I'm encountering a MultipeerConnectivity connection issue while developing a visionOS app and would like to ask if other developers have experienced similar problems.

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?

Samsung's Quick Share uses Wi-Fi Aware to achieve one-to-many concurrent sharing. Can Apple's Wi-Fi Aware achieve one-to-many concurrent sharing? Apple's AirDrop does support one-to-many concurrent sharing.

Hello all, WWDC 2025 introduced Wi‑Fi Aware (NAN) support on iOS 26 for peer-to-peer discovery and direct connections, but I noticed macOS Tahoe doesn’t include it. I couldn’t find any references to Wi‑Fi Aware APIs or framework support in the macOS SDK. Is Apple planning to bring Wi‑Fi Aware to macOS? If so, will this come in a future update to macOS 26 (e.g., 26.x), or is it deferred to macOS 27 or beyond? Thanks for any insights!

Is Apple's Wi-Fi Aware certified by the Wi-Fi Alliance? Is there any non-compliance of Apple's Wi-Fi Aware with the Wi-Fi Alliance standards? Does Apple have a roadmap to switch AWDL to Wi-Fi Aware? Does Apple have plans to adopt Wi-Fi Aware in Mac computers?

Im working on ios application that works with BLE device. The device uses BLE indications to provide data to the app. The goal is to achieve 100% data retrieval. According to the hardware team device behaves like this: CCCD Persistence: Device maintains Client Characteristic Configuration Descriptor (CCCD) with indication-enabled state across reconnections Resume Point: Device resends indications starting from the last unacknowledged indication before disconnection No Custom Logic: Follows standard BLE specification for indication reliability So it is expected that the device restores the indication streams from the last acknowledged one. My connection routine is: Discover services func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) { connectedPeripherals[peripheral.identifier] = peripheral peripheral.delegate = self updatePeripheralState(peripheral.identifier, to: .connected) print("Starting service discovery...") peripheral.discoverServices(nil) } Discover characteristics: func peripheral(_ peripheral: CBPeripheral, didDiscoverCharacteristicsFor service: CBService, error: Error?) { if let error = error { print("Characteristic discovery failed for service \(service.uuid): \(error.localizedDescription)") return } guard let characteristics = service.characteristics else { return } for characteristic in characteristics { if service.uuid == targetServiceUUID && characteristic.uuid == targetCharacteristicUUID { print("Found target characteristic! Enabling indications...") peripheral.setNotifyValue(true, for: characteristic) print(characteristic.properties.description) } } } Then the data retrieval: func peripheral(_ peripheral: CBPeripheral, didUpdateValueFor characteristic: CBCharacteristic, error: Error?) { if let error = error { print("Error reading characteristic value: \(error.localizedDescription)") return } if characteristic.service?.uuid == targetServiceUUID && characteristic.uuid == targetCharacteristicUUID { if let data = characteristic.value { let formatter = DateFormatter() formatter.timeStyle = .medium formatter.dateStyle = .none // data filtering since device is sending some other events sometims if data.count >= 15 { let event = decodeBytes(bytes: data) let now = Date() let timestamp = timestampFormatter.string(from: now) print("[\(timestamp)] Auto Increment: \(event.autoIncrement) Type: \(event.type)") } } else { print("Received indication with no data") } } } Using PacketLogger from xcode toolbox i have confirmed that: The device starts sending indications right after didConnect finishes The phone is sending ACKS for those indications Indications are not reaching didUpdateValueFor until peripheral.setNotifyValue(true, for: characteristic) properly executes This mekes me drop some data data on each reconnect. I already know I can do better in terms of service and characteristics discovery: I should discover only that one which is giving me the indications. But my intuition is: discover only the service and characteristic i care about will minimize the impact, but not guarantee 100% data retrieval Is this expected and confirmed CoreBluetooth behavior?

I'm writing an application that implements a Bonjour service and browser for the purpose of connecting to Logic Pro and interacting with a MIDI Device Script. Because it's connecting to Logic Pro running on the same system as the application, the service and browser do not need to access anything else on the local network. I'm creating the service and browser with calls like this: err = DNSServiceRegister( &serviceRef, 0, kDNSServiceInterfaceIndexLocalOnly, "MyService", "_osc._udp", "local", nullptr, 52854, txtLen, txtRecord, static_cast<DNSServiceRegisterReply>(myCallback), context ); err = DNSServiceBrowse( &browserRef, 0, kDNSServiceInterfaceIndexLocalOnly, "_osc._udp", nullptr, static_cast<DNSServiceBrowseReply>(browserCallback), context ); Despite the fact that I'm passing in kDNSServiceInterfaceIndexLocalOnly for the network interface, it still triggers an "Allow 'Application' to find devices on local networks?" permissions prompt. How can I avoid that prompt? It is both a significant failure point (in case users don't notice it or click 'Don't Allow' by mistake) but it may also scare them away, since it strongly implies my application is scanning devices on the local network, even though it's doing no such thing!

On iOS 26 beta 5, it is impossible to add a VPN configuration when a passcode is set on the device. Every time, all it does is redirect to the Settings app with no prompt for passcode. The only way around this is to disable passcode on the device so adding a VPN configuration doesn’t have to open the Settings app. This issue happened intermittently in the past with previous iOS 26 betas and even on iOS 18, but the problem has worsened on iOS 26 beta 5 to the point where you have to turn off passcode to add a VPN. Feedback ID: FB17974765

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.

I'm trying to distribute a sandboxed macOS app with a PacketTunnelProvider (system extension) via direct distribution (outside of AppStore). The app and the extension both use the same app group, using the new group.com.XXXX.YYYY format detailed here for 10.15+ https://developer.apple.com/forums/thread/721701 I've also followed the instructions below to get around the quirk of not being able to directly process it via XCode: https://developer.apple.com/forums/thread/737894 I've re-signed with Developer ID certificate, all that is smooth and successfully notarized. However upon running the app I get: "My.app" would like to access data from other apps. Checking ~/Library/Containers ~/Library/Group Containers I see the correct files folders have been created before I select Don't Allow and Allow. My app does not access any files or folders outside of the sandboxed directories. How can I prevent this from happening? In order to diagnose further, how to diagnose exactly which files/folder the app is trying to access that is causing this problem?

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!
