Device Activity monitor extension Not working
anyone has the same problem which is that your device activity extension ain't working even tho all the code work perfectly in the console, I setup it in the right way , tried to make schedule and it did the same exact thing when I tried to create usage threshold. anyone know the reason for this bug? here is my extension code import ManagedSettings import FamilyControls import Foundation import OSLog import UserNotifications class MonitoringExtension: DeviceActivityMonitor { private let defaults = UserDefaults(suiteName: group.com.William.app) private let logger = Logger(subsystem: com.William.app, category: MonitoringExtension) override func eventDidReachThreshold(_ event: DeviceActivityEvent.Name, activity: DeviceActivityName) { let activityRaw = activity.rawValue logger.info(Limite atteinte: (activityRaw)) scheduleNotification(title: Limite dépassée, body: Tu as utilisé trop de temps sur (activityRaw).) guard let data = defaults?.data(forKey: (activityRaw)_selection), let selection = try?

Reply to Background shield application reliability
Hi there! I am having a similar problem too. I use DeviceActivityMonitor to set 15 minute sessions for removing apps' shield. After 15-minute session is done, shield doesn't apply reliably in my internal testers. It applies if the tester is in my app or in blocked app but it doesn't if user's phone is locked or they are using another app. Although in my device it applies successfully when I build it from Xcode. This made me think whether this is a provisioning/build issue or a reliability issue (of device activity extension).

Stuck waiting on Family Controls distribution entitlement, first indie app, looking for guidance/timelines
Hi everyone, solo iOS dev here. I’ve built a small focus app (“Modo”) that uses Apple’s Screen Time APIs to help curb social-media overuse. In development everything works: FamilyActivityPicker for selection, a DeviceActivityMonitor extension for schedules, and ManagedSettings shields (plus uninstall guard only while “Blocked” is active). I requested the Family Controls distribution entitlement so I can ship, but my capability request has been pending for a while and I’m not sure what the usual path forward is. What I’ve already done • Submitted the capability request (Account Holder), describing the use case (self-control / digital well-being), user consent flow,. • Implemented app + DeviceActivityMonitor + ManagedSettingsUI extensions; verified the debug build has the right entitlements and behavior. • Regenerated profiles after the request; checked codesign entitlements on the built targets. • Filed a Developer Support ticket referencing the capability request. I really appreciate any tim

Reliable Shield enforcement for Parental Control App when child disables Notifications
We're building a parental control app using FamilyControls (.child authorization). Our architecture: Parent sends pause command → Firestore + FCM Child receives push → NotificationService Extension triggers main app Main app sets ManagedSettings Shields Problem: If child disables Notifications in Settings and force-quits the app, we cannot enforce Shields. What we've tried: Firestore Realtime Listener (works only when app is running) DeviceActivityMonitor (intervalDidStart/End only triggers at schedule boundaries, eventDidReachThreshold requires explicit app selection via FamilyActivityPicker) Question: Is there a recommended approach for parental control apps to reliably enforce Shields when the child has disabled notifications? Or is this a known limitation?

SCREEN TIME API is reporting false positives to DeviceActivityMonitor extension in iOS 26.2 & 26.3
Since the iOS 26.2 update, we have been experiencing anomalous behavior with the DeviceActivityMonitor extension when utilizing the ScreenTime API. Specifically, we are receiving the eventDidReachThreshold event within a few minutes of initiating monitoring, despite configuring a high usage limit. The process of turning off Screen Time -> restarting the device -> turning on Screen Time does not work. Any ideas? Thanks Filed Feedback Assistant: FB21560904

Family Controls entitlement not applying to DeviceActivityMonitor and ShieldConfiguration extensions
I have the Family Controls & Personal Device Usage entitlement approved for my main app target, but I'm unable to get it applied to my app extensions (DeviceActivityMonitor and ShieldConfiguration). The entitlement request form at developer.apple.com/contact shows Thank you for your submission when I submit requests for the extensions, but the requests never actually register. No follow-up email, no change in my account. Without the entitlement on these extensions, I can't use the core Screen Time API functionality (monitoring device activity and displaying shield UIs when apps are blocked). The main app target has the entitlement, but the extensions need it independently to function. Has anyone run into this? Is there a way to get the entitlement extended to app extensions, or is there a step I'm missing in the provisioning process?

Reply to Extract raw Screen Time data? Security says it's 'expected'
Hi, thanks for posting this — I've been hitting the exact same wall. I'm building a screen time management app and spent considerable time trying to persist per-app usage data from the DeviceActivityReportExtension to the App Group container. I exhaustively tested every storage mechanism available: Core Data, JSON files, UserDefaults (App Group suite), Keychain, raw POSIX syscalls, SQLite, iCloud KV, and NSUbiquitousKeyValueStore. All fail with permission errors — the extension is completely write-locked at the kernel level (POSIX errno 1 / EPERM). I also confirmed the DeviceActivityMonitor extension has the same restriction. So I'm very interested in your finding that the host app can reconstruct raw activity data from the report. Could you share more about the technique you used? Specifically: How does your host app access the data from the report extension? Is it through the rendered view hierarchy, some callback mechanism, or something else entirely? Are you able to get per-app bundle identifiers
