Hi, I’m implementing a NetworkExtension content filter provider on iOS and I can’t get it to activate on device. I have an iOS app (App Store distribution) with a content filter provider extension (NEFilterDataProvider). The app builds, installs, and runs fine, and the extension is embedded correctly. Entitlements appear to be set for both the app and the extension, and the extension’s Info.plist is configured as expected. However, when I try to enable the filter via NEFilterManager (loadFromPreferences → set configuration → isEnabled = true → saveToPreferences), saveToPreferences fails with NEFilterErrorDomain code 1 and the message “Configuration invalid or read/write failed.” The extension never starts and startFilter() is never called. Main app bundle ID: uk.co.getnovi.student Extension bundle ID: uk.co.getnovi.student.NoviContentFilter Extension type: NEFilterDataProvider We are testing on an iPhone 15 running iOS 18.6.2 (22G100), the app is designed to run on iPhone. This app is intended for education use on student-owned personal iPhones installed from the App Store. The devices we are testing on are not supervised and not enrolled in MDM. We already use the Family Controls framework (ManagedSettings) for app restrictions and have the com.apple.developer.family-controls entitlement enabled for App Store distribution. I’ve read TN3134 and noticed content filter providers on iOS are described as “supervised devices only” in general, with additional notes around iOS 15.0 for “apps using Screen Time APIs” and iOS 16.0 for “per-app on managed devices,” plus a note that in the Screen Time case content filters are only supported on child devices. My question is whether this error is what you’d expect when attempting to enable a content filter provider on a non-supervised, non-managed device, or whether this should still work if the entitlement and configuration are correct. If non-supervised devices are not supported, is there any supported path for enabling NEFilter on iOS without supervision/MDM (for example via the Screen Time / Family Controls child authorization pathway), or will the system always refuse to enable the filter on standard devices? In summary: is NEFilterDataProvider supported on non-supervised devices for consumer App Store apps, or is this a platform restriction that cannot be worked around? Thanks, Matt

I have an iOS app with a network extension that's using OSLog to log various bits of information that are useful for debugging. I'm currently trying to add a simple button that bundles up those logs with some other information and presents the user with a Share sheet so they can send it to support teams. I looked at OSLogStore but it only collects logs for the current process so the user clicking a button in my app wouldn't collect logs from my network extension. I would really like to avoid having to guide users through the process of creating and sharing a sysdiagnose but it seems like this might be the only option. How do other folks do this kind of thing? Is there a recommended way to do it?

I’m building a macOS app with a DNS Proxy system extension for Developer ID + notarization, deployed via MDM, and Xcode fails the Developer ID Release build with a provisioning profile mismatch for com.apple.developer.networking.networkextension. Environment macOS: Sequoia (15.7.2) Xcode: 26.2 Distribution: Developer ID + notarization, deployed via MDM Host bundle ID: com.mydns.agent.MyDNSMacProxy DNS Proxy system extension bundle ID: com.mydns.agent.MyDNSMacProxy.dnsProxy Host entitlements (Release): File: MyDNSMacProxy/MyDNSMacProxyRelease.entitlements: "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.application-identifier</key> <string>B234657989.com.mydns.agent.MyDNSMacProxy</string> <key>com.apple.developer.networking.networkextension</key> <array> <string>dns-proxy</string> </array> <key>com.apple.developer.system-extension.install</key> <true/> <key>com.apple.developer.team-identifier</key> <string>B234657989</string> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.application-groups</key> <array> <string>group.com.mydns.MyDNSmac</string> </array> <key>keychain-access-groups</key> <array> <string>B234657989.*</string> </array> </dict> </plist> xcodebuild -showBuildSettings -scheme MyDNSMacProxy -configuration Release : PROVISIONING_PROFILE_SPECIFIER = main MyDNSMacProxy5 CODE_SIGN_IDENTITY = Developer ID Application Host Developer ID profile main_MyDNSMacProxy5.provisionprofile (via security cms -D): "Entitlements" => { "com.apple.application-identifier" => "B234657989.com.mydns.agent.MyDNSMacProxy" "com.apple.developer.team-identifier" => "B234657989" "com.apple.security.application-groups" => [ "group.com.mydns.MyDNSmac", ..., "B234657989.*" ] "keychain-access-groups" => [ "B234657989.*" ] "com.apple.developer.system-extension.install" => 1 "com.apple.developer.networking.networkextension" => [ "packet-tunnel-provider-systemextension", "app-proxy-provider-systemextension", "content-filter-provider-systemextension", "dns-proxy-systemextension", "dns-settings", "relay", "url-filter-provider", "hotspot-provider" ] } So: App ID, team ID, keychain and system‑extension.install match.

Doesn’t match entitlements file value for com.apple.developer.networking.networkextension. Because of this, the app bundle isn’t produced and I can’t inspect the final signed entitlements. Questions: For com.apple.developer.networking.networkextension, should Xcode accept a subset of values in the entitlements (here just dns-proxy) as long as that value is allowed by the Developer ID profile, or does it currently require a stricter match? Is the following configuration valid for Developer ID + MDM with a DNS Proxy system extension: Host entitlements: ["dns-proxy"] System extension entitlements: ["dns-proxy-systemextension"] Host profile’s NE array includes the DNS Proxy system extension types. If this is a known limitation or bug in how Xcode validates NE entitlements for Developer ID, is there a recommended workaround? Thanks for any guidance.

Hello. We are facing very silent and hardly replicable issue. All UserDefaults.standard data the application saved and was using to determine the state of app is lost and app behaves as if it was freshly installed. The issue always occurs only if we leave app on background for long time or if we manually swipe the app from the background apps. In case we swipe, this issue can occur in minutes, hours or up to 2 days by our latest testing. One important factor is that the app was developed using iOS18 in which issue never occured. Next it was being tested on iOS26 and it did everytime. Any currently available version of iOS26 reported this issue, all the way up to 26.2.1 (23C71). Our application is going through major upgrade of its whole lifecycle and services so it is possible this issue is caused by a bug in development as the production version does not report this issue neither on iOS26 of any version. The following list contains how we tried to fix this issue but none of which helped. App prewarming in the background (postpone all initialization including searching UserDefaults.standard for when isProtectedDataAvailable) Calling UserDefaults.standard.synchronize() everytime after saving data despite it is not recomended Built app using different SDK's (tested on iOS18 and iOS26 SDK) Distributed the app from local machine aswell as on TestFlight itself We searched through currently opened and closed issues for third-party libraries app uses regarding 'iOS26' and 'UserDefaults', especially those who were added recently with no success. The structure using which we save data into UserDefaults.standard did not change, we have only added few more settings to save through the lifecycle of the app after update. We estimate the overall increase is merely 30% more of what it used to be in previous version. Any ideas are much appreciated. We are considering to use different or fully custom ways to store app's settings.

Currently, I have implemented Unwanted Communication Extension, But I wanted to send the reported call or message to my backed server. How can I achieve this and can I send message body to the server ?

When printing image/photo files via AirPrint, selected finishing options (e.g., Punch) are not applied unless a preset is chosen. reproduction steps: Select an image on iOS Tap Print → choose printer/server Set Finishing Options → Punch Print Observed: Finishing options not applied IPP trace shows no finisher attributes in the request working scenario: Select any Preset (e.g., Color) before printing Finishing options are then included in IPP and applied Note: Issue does not occur when printing PDFs from iOS; finisher attributes are sent correctly. Is this expected AirPrint behavior for image jobs, or could this be a bug in how iOS constructs the IPP request for photos?

With the same firmware, OTA testing on the DCL test network was successful in September 2025, and the Home app was able to deliver software update notifications. Since the beginning of 2026, however, the Home app no longer delivers software update notifications. This is bug number: FB21922369

Hi everyone, We are currently exploring ways to implement a frictionless Wi-Fi setup for our hardware devices without requiring a dedicated third-party application. We are interested in leveraging Apple's WAC (Wireless Accessory Configuration) to sync Wi-Fi credentials directly from iOS devices. However, we have struggled to find comprehensive technical documentation or specifications regarding the WAC service. Could anyone point us to the official source for these materials? Additionally, we have a couple of technical questions: 1.We are testing WAC provisioning and found that the Home app can discover our device and successfully get it online. However, it always ends with a "Failed to add accessory" message. Does WAC support imply that a device should be addable via the Home app? If not, why is the Home app able to discover and start the setup for a non-HomeKit WAC device? 2. Our device is already Apple AirPlay certified. Does implementing WAC require additional standalone certification, or is it covered under the existing MFi/AirPlay certification umbrella? Any insights or guidance would be greatly appreciated. Thank you!

I'll try to ask a question that makes sense this time :) . I'm using the following method on NSFileManager: (BOOL) getRelationship:(NSURLRelationship *) outRelationship ofDirectoryAtURL:(NSURL *) directoryURL toItemAtURL:(NSURL *) otherURL error:(NSError * *) error; Sets 'outRelationship' to NSURLRelationshipContains if the directory at 'directoryURL' directly or indirectly contains the item at 'otherURL', meaning 'directoryURL' is found while enumerating parent URLs starting from 'otherURL'. Sets 'outRelationship' to NSURLRelationshipSame if 'directoryURL' and 'otherURL' locate the same item, meaning they have the same NSURLFileResourceIdentifierKey value. If 'directoryURL' is not a directory, or does not contain 'otherURL' and they do not locate the same file, then sets 'outRelationship' to NSURLRelationshipOther. If an error occurs, returns NO and sets 'error'. So this method falsely returns NSURLRelationshipSame for different directories. One is empty, one is not. Really weird behavior. Two file path urls pointing to two different file paths have the same NSURLFileResourceIdentifierKey? Could it be related to https://developer.apple.com/forums/thread/813641 ? One url in the check lived at the same file path as the other url at one time (but no longer does). No symlinks or anything going on. Just plain directory urls. And YES calling -removeCachedResourceValueForKey: with NSURLFileResourceIdentifierKey causes proper result of NSURLRelationshipOther to be returned. And I'm doing the check on a background queue.

iOS BLE Background Scanning Stops After Few Minutes to Hours Hi everyone, I'm developing a Flutter app using flutter_blue_plus that needs continuous BLE scanning in both foreground and background. Foreground scanning works perfectly, but background scanning stops after a few minutes (sometimes 1-2 hours). Current Implementation (iOS) Foreground Mode: Scans for 10 seconds with all target service UUIDs Batches and submits results every 10 seconds Works reliably ✅ Background Mode: Rotates through service UUIDs in batches of 7 Uses 1-minute batch intervals Maintains active location streaming (Geolocator.getPositionStream) Switches modes via AppLifecycleState observer // Background scanning setup await FlutterBluePlus.startScan( withServices: serviceUuids, // Batch of 7 UUIDs continuousUpdates: true, ); // Location streaming (attempt to keep app alive) LocationSettings( accuracy: LocationAccuracy.bestForNavigation, distanceFilter: 0, ); Lifecycle Management: AppLifecycleState.paused -> Start background mode AppLifecycleState.resumed -> Start foreground mode Questions: Is there a documented maximum duration for iOS background BLE scanning? My scanning stops inconsistently (few minutes to 2 hours). Does iOS require specific Background Modes beyond location updates to maintain BLE scanning? I have location streaming active but scanning still stops. Are there undocumented limitations when scanning with service UUIDs in background that might cause termination? Should I be using CoreBluetooth's state preservation/restoration instead of continuous scanning? Info.plist Configuration: <key>UIBackgroundModes</key> <array> <string>bluetooth-central</string> <string>location</string> </array> Additional Context: Total service UUIDs: ~20-50 (varies by company) Scanning in batches of 7 to work around potential limitations Android version works fine with foreground service Location permission: Always iOS 14+ target Any insights on iOS BLE background limitations or best practices would be greatly appreciated. Thanks!

I have a network extension that hosts a NEFilterDataProvider & NETransparentProxyProvider. One of the use case that this caters to is : Proxy some flows (depending on originating app) while Content filter is also filtering flows based on business logic. The issue I am running into happens when FilterDataProvider sees a flow & responds with filterDataVerdict(withFilterInbound: false, peekInboundBytes: 0, filterOutbound: true, peekOutboundBytes:1024 to handleNewFlow(_ flow: NEFilterFlow) [wants to peek more bytes on outbound connection before making a decision] TransparentProxyProvider sees the flow & responds with NO to handleNewFlow(_ flow: NEAppProxyFlow) as it is not interested in in proxying that flow. When this occurs, we see connection being dropped by kernel. I wanted to know if this is expected behavior.

I have several macOS systems (Apple Silicon) running various flavours of macOS 26 (26.2 and 26.3 RC). I also have a couple of Centos 10 Linux (ARM64) systems. All are connected to my 10 GbE switch, so not routers or anything else in the path that could mess with ECN flags. The network is dual stack. The CentOS systems are configured to offer / accept ECN for both outgoing and incoming connections (net.ipv4.tcp_ecn = 1). The macOS systems have their default settings which also supposedly behave the same way: $ sysctl -a | grep ecn net.inet.tcp.ecn_timeout: 5 net.inet.tcp.ecn_setup_percentage: 100 net.inet.tcp.accurate_ecn: 0 net.inet.tcp.ecn_initiate_out: 1 net.inet.tcp.ecn: 1 net.inet.ipsec.ecn: 0 net.inet.mptcp.probecnt: 5 net.inet6.ipsec6.ecn: 0 net.classq.fq_codel.enable_ecn: 0 I have a simple throughput test program (written in C and using the standard socket API) that runs as both a client and a server which I have ported to both OS. When I run it between the two Linux systems using either IPv4 or IPv6 a tcpdump / Wireshark trace shows that ENC is active in both directions. Internet Protocol / Differentiated Services shows Explicit Congestion Notification: ECN-Capable Transport code point '10' for both flows. When I run the same test between one of the macOS systems and one of the Linux systems what I observe is that when using IPv4 the Linux -> macOS flow has Not ECN_capable Transport (0) while the macOS -> Linux flow has ECN-Capable Transport code point '10'. This seems wrong. I even tried enabling LS4 (defaults write -g network_enable_l4s -bool true) but unsurprisingly this made no difference. If I run the same test over IPv6 then both flows have ECN-Capable Transport code point '10'. How can I ensure that macOS tries to negotiate ECN for outgoing IPv4 connections? Or is this a macOS bug?

I’d like to confirm the expected behavior of StoreKit 2 in the Sandbox environment regarding unfinished consumable transactions across devices. Scenario: Device A and Device B are signed in with the same Sandbox Apple ID A consumable in-app purchase is completed on Device A The transaction may be verified or unverified, but transaction.finish() is not called The app is then launched on Device B and listens for Transaction.updates Question: In this scenario, is it expected that Device B will or will not receive a callback for this unfinished consumable transaction? Or is it by design that unfinished consumable transactions are not guaranteed to be delivered across devices, regardless of verification state?

Hello Apple Developer Community, I'm developing a cross-platform app using Flutter and the flutter_beacon library to handle iBeacon detection on iOS. My goal is to wake up the app in the background when it's in a killed/terminated state upon entering/exiting beacon regions, allowing for BLE communication (e.g., ranging or connecting to beacons). I've configured the necessary Info.plist keys for always location access and background location modes, and it works partially for single regions, but I have some specific questions/issues regarding reliability and limitations: Background Execution Time After Wake-Up: When the app is woken in the background by a region monitoring event (enter/exit) from a killed state, approximately how much time (in seconds) does iOS allocate for the app to run before suspending it again? Is this sufficient for performing BLE operations like ranging beacons or establishing a short connection, or are there stricter limits in terminated wake-ups compared to standard background modes? Monitoring Multiple iBeacons with Unique Identifiers: I need to monitor multiple iBeacon devices, each with potentially different UUIDs, majors, and minors. Can I add and monitor up to 20 regions simultaneously, each with a unique string identifier? If multiple beacons (from different regions) enter their respective ranges at around the same time, will the app receive separate callbacks for each region/identifier, or is there coalescing/prioritization that might cause only the last-added identifier to trigger notifications/events? Reliability in Killed State: In a fully killed state (e.g., force-quit via app switcher), does iOS reliably relaunch the app in the background for region monitoring events? Are there any known caveats, such as requiring specific hardware (e.g., iPhone models with certain Bluetooth chips) or iOS versions (targeting iOS 14+), and how does this interact with Flutter's background execution handling via the flutter_beacon library?

Hi, I tried to follow this guide: https://developer.apple.com/documentation/networkextension/filtering-traffic-by-url And this: https://github.com/apple/pir-service-example I already deploy the pir service on my server. And set the configuration on the app like this: { name = SimpleURLFilter identifier = xxxxx applicationName = SimpleURLFilter application = com.xxxx.SimpleURLFilter grade = 2 urlFilter = { Enabled = YES FailClosed = NO AppBundleIdentifier = com.mastersystem.SimpleURLFilter ControlProviderBundleIdentifier = com.xxxx.SimpleURLFilter.SimpleURLFilterExtension PrefilterFetchFrequency = 2700 pirServerURL = https://xxxxx/pir pirPrivacyPassIssuerURL = https://xxxxx/pir AuthenticationToken = AAAA pirPrivacyProxyFailOpen = NO pirSkipRegistration = NO } } But I got this error when I tried to enable the service on the app: Received filter status change: <FilterStatus: 'stopped' errorMessage: 'The operation couldn’t be completed. (NetworkExtension.NEURLFilterManager.Error error 9.)'> What does that error mean? And how to fix it?

Hi, I am trying to understand if I am able to get bluetooth scanning for advertisements (no service UUID) when the app is moved into the background and the screen goes to sleep. I am using swift on ios26.2 with a bluetooth class that uses the standard centralManager.scanForPeripherals to listen for particular Beacons. Testing on a real iPhone 15 this works fine whilst in the foreground, and also when on the lock screen. I am trying to get this to continue working in the background when the black screen sleep mode is on. I have the bluetooth 'Uses Bluetooth LE accessories' in the background modes (as well as Audio, Airplay..) and the necessary Bluetooth peripheral usage description, bluetooth always usage descriptions in info.plist. I launch a LiveActivity whilst the app is in the foreground and bluetooth has started scanning. From my understanding of core bluetooth with ios26 the LiveActivity should allow the scan to continue (without service UUIds and aggressive throttling) whilst the app is in the background. Well this seems to work fine.. if I press the side button the phone goes to the Lock Screen, and whilst on the Lock Screen the bluetooth is scanning fine and receiving beacon data. Similarly if the app is sent to the background behind a different foreground app it also works. As soon as the screen goes to sleep however (after only a few seconds of inactivity on the Lock Screen) then all bluetooth scanning stops. If I click back on the screen and bring the Lock Screen up, then scanning resumes again. Now is it possible to continue the scanning whilst the phone is in sleep mode (i.e. black screen)? Are there any additional acceptable steps to make the bluetooth scanning continue when the screen has gone to sleep. Or is it part of the design with core bluetooth that the 'continues in the background' feature only applies to the lock screen and when other active apps are brought to the foreground on an open phone. I want to understand the limitations of what can be achieved so I am not chasing unachievable objectives. Thanks

Our app is supposed to be removed from sale on May 31st. Subscriptions our app is offering will also be removed on May 1st one month before our app removal. I would like to know if AppStoreServerNotificationV2 EXPIRED event will be sent to a specified endpoint after the removal of these subscriptions. I think each subscription will be canceled automatically from May 1st to May 31st and it will send EXPIRED event to our server, but is it true? Thank you in advance.
