Overview

Our current business goal is to improve the success rate of iBeacon wake-up on iOS. Apple's official iBeacon specification recommends a standard broadcast interval of 100ms; Now we are planning to shorten the broadcast frequency to 50ms, and we would like to consult the full dimensional impact of this change, and whether it can really improve the success rate of beacon identification and pull trigger on iOS devices.

I activated the Paid Apps Agreement today along with banking and tax information. My app uses react-native-purchases (RevenueCat) with StoreKit 2. When tapping purchase buttons in TestFlight I still get "Product not available - Could not load this product." Products show "Waiting for Review" in App Store Connect. Sandbox tester is configured. Is there a delay after activating the Paid Apps Agreement before sandbox purchases work? How long should I expect to wait?

Hi everyone, I am seeking clarification regarding the communication capabilities between an ESP32 microcontroller and Apple's latest devices, specifically the iPhone 16 Pro Max and iPad Pro, both equipped with USB-C ports. Background: MFi Certification: Historically, establishing communication between external devices and iOS devices required MFi (Made for iPhone/iPad) certification. But I remember this being necessary in the Lightning Cable to USB era. With the introduction of USB-C ports in recent iPhone and iPad models, there is an indication that MFi certification may no longer be necessary for certain peripherals. Perhaps I'm not confident on the terminology here: https://mfi.apple.com/en/who-should-join Project Requirements: I am working on a sensor research project that necessitates the collection of low-latency time-series data from an ESP32 microcontroller, which features a USB-C port. The data needs to be transmitted to an iPhone 16 Pro Max or iPad Pro. Bluetooth communication has proven insufficient due to its limited data transfer rates (~1.2 Mbps with L2CAP). While NEHotspot could be an alternative, it restricts the iPad's internet connectivity. Therefore, establishing a direct USB-C connection between the ESP32 and the iOS device appears to be the most viable solution. Questions: MFi Certification Necessity: Is MFi certification still required for an ESP32 microcontroller to communicate with iPhone 16 Pro Max or iPad Pro via USB-C? USB-C Communication Support: Do the iPhone 16 Pro Max and iPad Pro natively support serial communication over USB-C with microcontrollers like the ESP32? If not, are there recommended protocols or interfaces to facilitate this communication? App Development Considerations: Would developing a custom iOS application be necessary to handle data transmission from the ESP32 over USB-C? If so, are there specific APIs or frameworks provided by Apple to support this functionality? Data Transfer Rates: Considering the need for high-speed data transfer, are there any limitations or considerations regarding the data transfer rates achievable through a USB-C connection between the ESP32 and iOS devices? Thank you!

I'm building a custom keyboard extension that offers voice dictation. Because keyboard extensions are constrained (memory cap ~30–48 MB, restricted audio session access), I delegate recording to my container app: User in a host app (e.g., Safari) taps the mic in my keyboard extension. The keyboard calls extensionContext.open(URL("myapp://dictation")) to launch the container app. The container app records audio via AVAudioEngine + SFSpeechRecognizer, writes the final transcript to the App Group, and signals completion via a Darwin notification. 4. The user is expected to be returned to the original host app (Safari) automatically so they can keep typing. The problem (step 4): On iOS 26.4 I can no longer identify which app was the host. Every previously-known path returns nil for the keyboard extension's host: parent.value(forKey: "_hostBundleID") → returns the literal string parent.value(forKey: "_hostApplicationBundleIdentifier") → returns NSNull xpc_connection_copy_bundle_id on the underlying XPC connection (via PKService.defaultService.personalities[…]) → returns NULL NSXPCConnection.processBundleIdentifier on extensionContext._extensionHostProxy._connection → returns nil proc_pidpath(hostPID, …) → EPERM from the keyboard sandbox LSApplicationWorkspace.frontmostApplication → selector unavailable from the extension RBSProcessHandle.handleForIdentifier:error: → returns an RBSServiceErrorDomain error Without the host's bundle ID, the container app has no way to call LSApplicationWorkspace.openApplicationWithBundleID: (the technique that worked on iOS 25 and earlier). UIApplication.suspend() correctly sends the container to background, but iOS treats us as a "fresh launch" — it returns the user to the Home Screen instead of Safari, because the container app was launched by an extension, not directly by Safari. KeyboardKit's maintainer reached the same conclusion (issue #1014) and shipped 10.4 without the feature. My questions: Is there a public, App-Store-safe API in iOS 26+ for a custom keyboard extension to identify its host application, or for the container app (launched via the extension's openURL) to identify which app initially hosted the extension that opened it? UIOpenURLContext.options.sourceApplication reports the extension's own container, not the actual host. 2. Is there a public mechanism for "return to source app" when the container app was launched by an extension's openURL? Equivalent to the ← Source affordance iOS shows for normal inter-app openURL, but triggered programmatically by the launched app. 3. Some popular keyboards (e.g., 微信输入法 / WeChat Keyboard) still appear to round-trip through their container app on iOS 26.4 and return the user to the original host — including the iOS ← WeChat back affordance in the host's status bar afterward. What's the recommended approach to achieve this? If it requires a specific scene-activation flow, NSUserActivity pattern, or extension-context configuration, please point at the relevant docs. 4. If there is no public path today, is FB22247647 (or a related radar) the right place to track this? Should developers in this position migrate to in-extension audio capture (which has its own significant constraints in keyboard extensions)? I'd much rather not rely on private APIs. Concrete guidance — or even an acknowledgment of which direction Apple intends — would help thousands of custom-keyboard developers who currently have a degraded voice-input experience on iOS 26.4+. Tested on iPhone 12 Pro Max running iOS 26.4.2 (build 23E261), Xcode 26.x, Swift 5. Thanks!

I have a custom keyboard (UIInputViewController, Full Access). For a dictation feature it opens its containing app to record audio (the keyboard can't use the microphone) and then needs to return the user to the host app they were typing in. That requires knowing the host app. Through iOS 26.3 this worked, because the host bundle id was exposed on the keyboard's input-session connection. On iOS 26.4 / 26.5 it is now nil, and every route I have tried is blocked: UIInputViewController _hostApplicationBundleIdentifier -> nil _hostProcessIdentifier and the host audit token are available, but: RBSProcessHandle handleForAuditToken: / handleForIdentifier: -> "Client not entitled" SecTaskCopySigningIdentifier / SecTaskCopyValueForEntitlement -> nil (sandbox) proc_pidpath -> EPERM UIKeyboardImpl _remoteAppId / _remoteLocalizedAppName -> nil The keyboard arbiter client-change event fires in SpringBoard, not in the extension process However, at least one shipping keyboard still does this on iOS 26.5. I verified in device logs that Yandex Keyboard launches its container app with a URL containing the correct, current host bundle id, and it is live: it reported net.whatsapp.WhatsApp, then net.whatsapp.WhatsAppSMB when the host was WhatsApp Business. So the capability clearly still exists for some apps. Questions: Is there a supported API on iOS 26.4+ for a keyboard extension to identify its host app? If it requires an entitlement, can developers request it, and how? If there is no public path, is the intended approach the system "back to previous app" breadcrumb (manual) plus a containing-app round trip? I have also filed Feedback (FB#######). Thanks.

Case ID: 102924093872 Case ID: 102924089648 Hi Apple Support Team, I’m reaching out regarding a critical issue that is blocking my app testing and affecting hundreds of users. I cannot receive the two-factor authentication code for my Apple Developer account. My mobile operator has confirmed that SMS messages from Apple are not reaching their network at all. I also receive no calls. Since my account is not logged in on any device, SMS is the only way I can verify my identity - and it’s not working. I have already submitted two support cases but have not received any response yet. Here is the impact this is having right now: • 250+ people are waiting to get access to test my app • 400 users are already using the app • I cannot sign the new agreement that appeared in App Store Connect • Because of this, TestFlight is completely blocked - both the 10,000 user limit and the 100 user internal testing • Even when I add someone to my team and grant them access, it still doesn’t work for them either I have been building this app for almost 7 months. We are in the final testing stage before I plan to release it for sale. Every day without access is a day my users are waiting and I cannot move forward. I am asking you to please help me resolve this as quickly as possible. I really need your support right now. Thank you so much for your time. Best regards, Tata

Environment: iOS 26.5, Message Filter app extension (IdentityLookup framework), offline filtering. Setup My Message Filter Extension performs offline string matching on the message body and returns one of: ILMessageFilterAction.allow / .junk / .transaction / .promotion In the Messages app the filtering UI shows these folders: Messages (the main/default folder), Transactions, Promotions, Junk. .allow is expected to surface a message in the main Messages folder. The documented behavior (API docs + WWDC22 "Explore SMS message filters") only describes a static mapping from action → folder. On iOS 26.5 I'm seeing what looks like a stateful, per-sender behavior that I cannot find documented anywhere, and I can't tell whether it is intended or a bug. Test methodology All messages in every sequence are sent from the same single phone number. Before each Case, I fully clear the receive history for that number, so every sequence starts from a clean slate with no prior state for that sender. The notation shows how many conversations/entries appear in each folder after each step. Case A — first message = allow allow → Messages: 1 promotion → Messages: 2 (allow + promotion), Promotions: 1 junk → everything collapses into Junk; Messages & Promotions become empty every subsequent message lands in Junk regardless of the action I return Case B — first message = allow, then transaction allow → Messages: 1 transaction → Messages: 2 (allow + transaction), Transactions: 1 junk → everything collapses into Junk; Messages & Transactions empty every subsequent message lands in Junk regardless of returned action Case C — first message = transaction transaction → Messages: 1, Transactions: 1 ← also appears in Messages allow → Messages: 2, Transactions: 1 promotion → Messages: 3, Transactions: 1, Promotions: 1 junk → Messages: 4, Transactions: 1, Promotions: 1, Junk: 1 (NOTE: here junk does NOT collapse the thread, and there is no "sticky junk") Case D — first message = promotion promotion → Promotions: 1 only (does NOT appear in Messages) allow → Messages: 2 (the earlier promotion now also appears in Messages), Promotions: 1 junk → everything collapses into Junk (sticky, same as Case A/B) every subsequent message lands in Junk regardless of returned action My core question: are the following two behaviors by design, or are they bugs? (1) "Sticky junk" after allow-first / promotion-first. In Cases A, B and D, once .junk is returned the whole sender thread collapses into Junk, and from then on every message is forced into Junk regardless of the action my extension returns. Is this expected/by-design, or a bug? If by design: is it permanent, and what resets it — does the extension have any control, or is it purely user-driven (e.g. the user moving the thread out of Junk)? What concerns me is that the system appears to ignore my returned action entirely once this state is entered. (2) .transaction-first behaving differently from .allow-first. A sender whose first message is .transaction (Case C) behaves differently: the message also appears in the main Messages folder, and a later .junk does not collapse the thread (no sticky junk). Is this .transaction-first behavior expected/by-design, or a bug? If by design, what is the underlying rule that makes .transaction-first confer this state while .allow-first does not? Since the history is cleared before each test, this is determined purely by the first action returned. Additional clarifying questions Is any of this per-sender state behavior documented beyond the static action → folder mapping in the API docs / WWDC22 "Explore SMS message filters"? If so, where? More generally, what determines whether a categorized (.transaction / .promotion) message is also mirrored into the main Messages folder? Thanks — I'd like my extension's return values to produce predictable categorization for users, and right now this first-message-dependent behavior makes that hard to reason about.

Hello everyone, I am facing a severe issue with my app's review process and urgently need some guidance or advice on how to resolve this bottleneck. Current Situation: Our latest version has been stuck in the "Waiting for Review" status for the past 10 days. Yesterday, after reading some community advice, I used "Cancel Submission" and re-submitted the build to try and refresh the queue. Unfortunately, it is still completely stuck in the exact same "Waiting for Review" status with no progress. Past History: This seems to be an ongoing issue with our account. For our previous versions, the App Review team took an incredibly long time—between 1 to 1.5 months for each submission—only to ultimately issue a rejection. We have already tried sending 5-6 standard support requests and even requested an expedited review 3 times, but we have received absolutely zero response or feedback from Apple. It feels like our app or account is stuck in some sort of dead-end queue. Has anyone else experienced such extreme delays just waiting for the review to start? Is there any alternative way to escalate this to a human specialist at Apple who can check if there's an account-level glitch? App Store URL: https://apps.apple.com/uz/app/fonus-kids/id6742020368 Thank you in advance for any insights or help!

I’m developing a watchOS app that records outdoor soccer workouts using HealthKit. My app starts a workout session with: HKWorkoutConfiguration.activityType = .soccer HKWorkoutConfiguration.locationType = .outdoor HKWorkoutSession HKLiveWorkoutBuilder HKLiveWorkoutDataSource During the workout, I display distance from the live builder statistics: HKQuantityType.quantityType(forIdentifier: .distanceWalkingRunning) After the workout ends, I save the workout using finishWorkout(), and later read the saved distance from: HKWorkout.totalDistance?.doubleValue(for: .meter()) So the total distance shown in my app is not calculated manually from GPS route points. It comes from HealthKit’s workout distance. I noticed a difference between soccer workouts recorded by Apple’s built-in Workout app and soccer workouts recorded by my third-party watchOS app. Example comparison: Apple Workout app soccer: Active duration: about 88 min Steps: about 8,832 Distance: about 6.7 km No visible route/location data in Fitness My watchOS app soccer: Active duration: about 87 min Steps: about 8,998 Distance: about 5.6 km Includes route/location data Workout recorded through HKWorkoutSession + HKLiveWorkoutBuilder Distance read from HKWorkout.totalDistance The step counts and active durations are very close, but the distance differs by about 1.1 km. One important detail is that the Apple Workout app soccer workout does not appear to include visible route/location data in Fitness, while my third-party workout does include route/location data. Despite that, the Apple Workout app reports a longer distance. So the comparison is not simply “GPS route distance vs GPS route distance”. It looks like the built-in Workout app may be estimating soccer distance without exposing route data, while HKLiveWorkoutBuilder for a third-party .soccer workout may be producing a different totalDistance estimate. My questions are: When the built-in Apple Workout app records an outdoor soccer workout without exposing route data, how is totalDistance estimated? Is that distance estimation behavior available to third-party watchOS apps using HKWorkoutSession + HKLiveWorkoutBuilder with .soccer? If a third-party app records route data for the same soccer activity, can that change how HealthKit calculates totalDistance compared with a no-route built-in Workout app recording? For third-party soccer workouts, should developers expect HKWorkout.totalDistance to match the built-in Workout app, or is a difference expected? Is there any additional configuration, entitlement, data type, or best practice required to get more accurate distance estimates for soccer workouts? Any clarification on the expected behavior would be very helpful. Thanks!

Hello Everyone, I am a student from India who is passionate about technology, coding, and design. I would like to propose a precise hardware and software design enhancement regarding the "LED Flash for Alerts" feature on the iPhone. Current Limitation: The existing feature utilizes the main camera flash/torch. While functional, it is incredibly bright and harsh, causing visual discomfort in dark rooms, study spaces, or classrooms. My Specific Idea: Instead of using the blinding main flash, Apple could integrate a subtle, soft white LED indicator directly inside or underneath the small black circle element located on the camera module (the sensor/microphone area). When a notification or call arrives, this exact black circle should softly pulse or glow with a clean, ambient white light. Benefits: Precision & Aesthetics: It utilizes an existing design element to create a beautiful, minimalist, and non-disruptive visual alert. User Experience: It provides a soft indicator that doesn't blind the user or disturb others in low-light environments. Power Efficiency: Illuminating a tiny dedicated ring/circle consumes significantly less battery than firing the main camera torch. As a student, I believe this subtle refinement would make the iPhone experience feel even more premium and thought-out. I would love to hear what Apple engineers and the developer community think about this!

Hello, My name is Jisoo Kim, and I am a product designer currently developing a tray and case accessory for the Apple Magic Keyboard and Magic Trackpad. I have reviewed the Apple Accessory Design Guidelines, however I was unable to find specific guidance covering accessories of this type. As a designer and an engineer who values complementing Apple's devices without interfering with their functionality, I want to ensure our development aligns with Apple's standards. Given the absence of specific guidelines for this product category, I have two questions: Would it be appropriate to reference guidelines from other similar Apple accessory categories as a basis for our design decisions? Are there any additional considerations or requirements we should be aware of when developing this type of accessory? Any guidance you could provide would be greatly appreciated.

Hello, I am implementing background processing using Silent Push Notifications in an iOS application. The app needs to receive requests from a server and execute processing in the background. For this purpose, I am using Silent Push Notifications to wake up the application. However, the application is not being launched as expected when running the TestFlight version. I would appreciate any guidance regarding this behavior. Environment Xcode 26.3 iOS 18.6 TestFlight distribution Push Notifications capability enabled Background Modes enabled Remote notifications enabled APNs Authentication Key (.p8) APNs Production environment Background Previously, the application periodically connected to a server in the background and sent location information when requested by the server. Since that background processing no longer behaves as expected, I started implementing an alternative approach using Silent Push Notifications. When running the application directly from Xcode in Debug mode, Silent Push works correctly and the app is launched in the background. However, when using the TestFlight build on the same device, the behavior differs and the app is not launched in the background. Observed Behavior The APNs request appears to be successful: APNs response status is HTTP 200 Using the device token obtained from the TestFlight build Alert Push notifications are received successfully application:didReceiveRemoteNotification:fetchCompletionHandler: is called when the app is in the foreground The same method is not called when the app is in the background Silent Push payload: { "aps": { "content-available": 1 } } HTTP/2 headers: apns-push-type: background apns-priority: 5 Verified Items Production device token is being used APNs topic matches the application's bundle identifier Alert Push notifications work correctly Background App Refresh is enabled on the device The application has not been force-quit completionHandler is always called after processing completes Console Logs The following logs appear when the push is sent: Submitted: com.apple.pushLaunch.jp.co.comp.MyApp.ext.mdm Application Policy response: {100, 0.00, [{[pushDisallowed]: Required:0.00, Observed:1.00},]} Decision: AMNP I also see: Insufficient history window for deviceActivityLikelihood stream deviceActivityLikelihood returned a nil timeline Questions Under what conditions are pushDisallowed and Decision: AMNP generated? What factors can cause iOS to reject a background launch triggered by a Silent Push Notification? Since Alert Push notifications are received successfully, is it reasonable to conclude that APNs configuration, topic configuration, and device token usage are correct? Are there any specific settings, entitlements, or implementation details that should be reviewed to resolve the pushDisallowed condition? The behavior differs between the Debug build launched from Xcode and the TestFlight build running on the same device. Are there any restrictions, policies, or differences applied to TestFlight builds that could explain this behavior? If the observed behavior is expected by design, what would Apple recommend as the appropriate architecture or API for server-triggered background processing in this scenario? Thank you for your time and assistance.

Hi, If I try and add ANY build to an external test group in TestFlight, I get this: There was an error processing your request. Please try again later. "errors" : [ { "id" : "87a4291a-8d19-407c-9065-8013bcaf1ade", "status" : "400", "code" : "PARAMETER_ERROR.REQUIRED", "title" : "A required parameter was not provided", "detail" : "The parameter 'filter[build]' is required but was not provided", "source" : { "parameter" : "filter[build]" } } ] } I have no idea what's the issue. Any ideas?

Hi, I'm having a strange issue with my new MacBook Pro M5. My iPhone 17 is connected via USB. The phone appears in Finder, so the Mac clearly detects it, and I can access it there. However, the Xcode doesn't see the iPhone at all. Both the MacBook Pro and the iPhone are running version 26.5. What's confusing is that the exact same iPhone and the exact same USB cable work perfectly with my older Intel-based MacBook Pro. Has anyone else experienced this, or have any suggestions on what I should check?

Hello Applet, I’m experiencing an issue with StoreKit on a TestFlight build. My app uses auto-renewable subscriptions through StoreKit and RevenueCat. Configuration already verified: App installed through TestFlight (not debug). Bundle Identifier: com.ciborgu.vytalai Paid Applications agreement is active. In-App Purchase capability is enabled. Three auto-renewable subscriptions exist in App Store Connect. Product IDs match exactly between App Store Connect, RevenueCat and the application. RevenueCat initializes successfully. A Sandbox test account has been created. Tested on a physical iPhone. Device restarted and app reinstalled from TestFlight. VPN and iCloud Private Relay disabled. When attempting to purchase a subscription, the Apple payment sheet never appears. Our diagnostics indicate that StoreKit does not return any available products for the configured Product IDs, preventing the purchase sheet from opening. Expected Product IDs: vytalai_premium_monthly vytalai_premium_yearly vytalai_premium_yearly_intro Could you please verify if there is any issue with the App Store Connect configuration, StoreKit availability, or the processing state of these subscriptions on Apple’s side? If additional logs or diagnostics are required, I can provide them. Thank you. I have already contacted Apple Developer Support regarding this same issue. Previously, I was advised to schedule a technical support meeting. However, when I requested the meeting, my request was declined because of the subject of my issue, so I was unable to speak with an Apple engineer. Since I have now completed all the recommended troubleshooting and the issue still persists, I would greatly appreciate it if this case could be reviewed by the appropriate technical team or a StoreKit engineer. Thank you for your assistance.

I wonder is anyone at Apple still using Interface Builder for anything… Across Xcode 16.x and 26.x, IB has become increasingly and noticeably slower to open storyboard and xibs. I see zero improvements in Xcode 27 beta. This morning I had both 26 and 27 going fairly quickly into "application not responding" state when trying to render a rather simple layout in storyboard. What's making it worse is that force-quitting the app and starting again leads straight back into the same storyboard and then locks up again. It does not matter if I manage to switch to a .swift file — it's clearly still doing something in the background related to that storyboard and gets stuck. I eventually managed to open just the .storyboard (without the project), fix the offending layout bits and now it's at least not getting stuck although it still takes good 5-6s before it renders a layout with about a dozen components. I assume something with LLM agents is the reason for this issue but come on people — this is infuriatingly incapacitating tool for people like me that are still maintaining UIKit apps.

Hello, I have a problem with the Retention Message API. The default message is not displayed to users when they try to cancel their subscription in the device's Settings app. The API configuration was made with Revenue Request. The request to use this API was approved by Apple for our account. After configuring it for the Sandbox environment, everything worked as expected the image and text were displayed to users. Later, I applied the same configuration to the Production environment. I received the Approved status for the message, but after purchasing the subscription from the App Store, although I can see the subscription in Settings, the retention message is not displayed when I attempt to cancel it. I have tried different Apple accounts from different regions (both EU and non-EU) and tested from physical locations without using a VPN. Also, for clarification, we do not use real-time communication only the default retention message. For additional information: I also tried configuring this message from App Store Connect, as shown in WWDC 2026, but this section is not available under the Subscriptions category. When I deactivate and then reactivate the message, I notice that the deactivated state shows the text status "Waiting for sync (0/9)", while the active state shows "Approved". All other assets have an Approved state. In my case, the message is configured for all subscription types without any filters or other restrictions. What could be causing this problem, and how can I fix it? It seems that the issue is not on my side.

I have a photo editing app that owns no photo library. I want a user viewing an image in another app (e.g. Photos) to say "filter this image in MyApp" and have Siri hand that on‑screen image to my intent. Targeting iOS 27. What I've tried, and the result in each case: • App Shortcut + @Parameter var image: IntentFile — Siri resolves my other parameters (a filter AppEnum) by voice, but never binds the image; the run fails. • @AppIntent(schema: .photos.setFilter) with a .photos.asset entity — never routes from Photos. • @AppIntent(schema: .system.open): OpenIntent with a custom AppEntity target — "Open this image in MyApp" just launches the app by name; perform() is never called, and the entity query never runs. My understanding from WWDC26 "Build intelligent Siri experiences with App Schemas" (session 240) and "Discover new capabilities in the App Intents framework" (session 345): • Cross‑app content transfer (Transferable + IntentValueRepresentation) seems limited to system value types (IntentPerson, PlaceDescriptor); IntentFile is not a _SystemIntentValue, so an image can't ride that rail. • Onscreen awareness (NSUserActivity.appEntityIdentifier, View Annotations) appears to expose only the foreground app's own content — which here is Photos, not me. Question: Is there a supported way for a third‑party app to receive another app's on‑screen image (vs. a contact/place) through Siri/App Intents today? If so, which API carries the pixels — an IntentFile parameter, @UnionValue, IntentValueQuery, something else — and what must the source app do to make it available? Or is asking "do X to this image in <third‑party app>" simply not supported yet outside Shortcuts?

We are using a Content Filter Network Extension to perform telemetry over the network activity of enterprise iOS devices. The filter itself is not blocking any connection. We encountered an issue where our Content Filter got stuck in a deadlock in the startFilter method of the NEFilterControlProvider. This resulted in a crash report where we see 64 threads stuck in the startFilter call. While the content filter was stuck in a deadlock, the device network connectivity was lost. We solved the deadlock issue coming from our logger, however, we would like to get a better understanding on the following points: What are the critical paths where a Content Filter can have a device wide impact on network connectivity? What is the behavior of the OS when the Content Filter is unresponsive (e.g. in startFilter, handle(Report), handleNewFlow)? Will it try to start the filter again? Force kill it ? We saw that startFilter was called multiple times in our crash reports whereas we expected it to be called only on vendor configuration changes. What is the lifecycle of the filter control provider and filter data provider ? When are the different methods like startFilter called ? We would like our Content Filter to never cause disruptions and implement a circuit breaker behavior in case any issue occurs. Do you have any recommendation on how to achieve this ?

Our vehicle digital key app uses CBCentralManagerOptionRestoreIdentifierKey and bluetooth-central background mode to maintain BLE connections with cars. We want to confirm: if the app is actively connected to a BLE vehicle peripheral and then terminated by system memory reclamation (not user force-quit), will iOS automatically relaunch the app via Bluetooth State Restoration when the peripheral sends notifications or re-advertises? Also please list all mandatory conditions to trigger such Bluetooth-based background relaunch after system termination, and clarify whether this pure-BLE relaunch channel works independently apart from iBeacon location-triggered cold launch for our terminated app on iOS 26 without AccessorySetupKit. Best regards
