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

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?

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

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?

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

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).

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?

Screen Time differences between DeviceActivityMonitor and times shown in DeviceActivityReport
I am still struggling to nail down the screen time between monitoring and showing it in a DeviceActivityReport. It's always off by a couple of percentage points, which results in a difference of a couple of minutes between the time shown for my total screen time in DeviceActivityReport and DeviceActivityMonitor with a threshold set for all apps/websites/categories. In the report, I am looping through all segment (there is only 1 segement using .daily segment interval for a given day) then loop through all categories and all apps within each category and sum up all totalActivityDuration for each app. Based on avaiable documentation, that should corrolate to DeviceActivityMonitor threshold but it doesn't. Are there any differences in how these 2 places count screen time? Are there any apps/core ios services which are excluded from DeviceActivityMonitor. Would appreciate any help at all, I'm losing my mind here. My current suspicion is that Apple Developer documentation is counted twic

DeviceActivityMonitor will automatically become invalid
I started monitoring using the following code: deviceActivityCenter.startMonitoring( DeviceActivityName(name), during: makeDailySchedule(), events: events ) Where: DeviceActivitySchedule( intervalStart: DateComponents(hour: 0, minute: 0), intervalEnd: DateComponents(hour: 23, minute: 59), repeats: true, warningTime: nil ) In DeviceActivityMonitor, I read and write data using UserDefaults and keep the logic minimal to ensure the size does not exceed 6MB. However, after a period of time, monitoring continues to fail. Why is this happening? How can I resolve this issue?

Screen Time API, DeviceActivity, Family Controls, Entitlements, Provisioning Profile
Hello everyone, I'm hoping to find a solution for a critical issue that is blocking my app's submission to the App Store. My app uses the Screen Time API and therefore has a main app and a DeviceActivityMonitor extension. The main app has been successfully granted the Family Controls (Distribution) entitlement. However, the DeviceActivityMonitor extension is stuck with only the Family Controls (Development) entitlement. This mismatch causes my build to fail during the archive/distribution process with the error: Provisioning profile failed qualification. Profile doesn't support Family Controls (Development). This is a hard blocker, as the extension is a mandatory part of the API. I have already filled out the entitlement request form and also contacted Developer Support (Case #102666581576), who confirmed they could not assist and directed me here. My question is: What is the correct procedure to escalate or resolve the issue of a required extension not receiving the distribution-level Famil

Family Controls (Distribution) entitlement missing for Device Activity Monitor extension - blocking TestFlight distribution
Hi Apple Developer Community, I'm experiencing an issue with Family Controls entitlements for my iOS app that I'd like to discuss and see if others have encountered similar problems. Background: My app (BrightStart) uses Family Controls to help users build healthy morning routines by temporarily blocking distracting apps until they complete a sunlight exposure session. The core functionality relies on automatic time-based blocking (e.g., block social media apps from 6-8am daily). The Problem: I have Family Controls working perfectly in development builds, but I'm blocked from distributing via TestFlight due to entitlement issues with my Device Activity Monitor extension. Technical Details: Main app bundle ID: app.brightstart.app ✅ Has both Family Controls (Development) and Family Controls (Distribution) options available Extension bundle ID: app.brightstart.app.BrightStartMonitorExtension ❌ Only shows Family Controls (Development) - no Distribution option Error when archiving for TestFlight: ❌ Provisioning pr

Provisioning Profiles Missing Family Controls Child Entitlements Despite Development Approval
Hello everyone, I'm facing a critical build issue related to Family Controls entitlements and would appreciate any insights or help from the community or Apple engineers. My Goal: I am trying to build and run my app on a physical device to test my DeviceActivityMonitor and ShieldConfigurationExtension. I have already been approved for the Family Controls (Development) entitlement. The Problem: When I try to build, Xcode fails with the following errors, preventing me from testing: For my DeviceActivityMonitor target: Provisioning profile ... doesn't include the com.apple.developer.deviceactivity entitlement. For my SOSAppShieldExtension target: Provisioning profile ... doesn't include the com.apple.developer.screen-time-api entitlement. The Core Evidence: This seems to be a server-side issue with how the provisioning profiles are generated. I have used the security cms -D -i command to inspect the downloaded .mobileprovision files. The inspection reveals that the profiles do contain the paren

DeviceActivityEvent will still execute even if the app is not in use
I use DeviceActivityCenter to monitor app usage. For DeviceActivityEvent, I set 30 events, and the threshold of each event increases by 2 minutes: var events: [DeviceActivityEvent.Name: DeviceActivityEvent] = [:] for index in 0..<30 { let threshold = (index == 29) ? DateComponents(hour: 1) : DateComponents(minute: (index + 1) * 2) let name = DeviceActivityEvent.Name((prefix)|(index)) events[name] = DeviceActivityEvent(applications: tokens, threshold: threshold) } After reaching the last DeviceActivityEvent, I will restart directly in DeviceActivityMonitor private func restartMonitoring(activity: DeviceActivityName) { let center = DeviceActivityCenter() let currentEvents = center.events(for: activity) do { try center.startMonitoring(activity, during: schedule, events: currentEvents) } catch { print(Fail: (error)) } } But I found that after restarting, DeviceActivityEvent will be automatically executed even if I don't use the app. My iOS version is 18.5

Screen Time API: How to map bundleIdentifier to ApplicationToken for DeviceActivityMonitor when FamilyActivitySelection.Application.bundleIdentifier is nil?
I'm using FamilyActivityPicker to get consent for app/category management, which returns a FamilyActivitySelection object. I serialize this FamilyActivitySelection object (just applicationTokens and categoryTokens) and pass it to my DeviceActivityMonitor extension via App Group UserDefaults. I am using the JSON encoder/decoder over PropertyList (though both seem to exhibit the same behavior). After inspecting the FamilyActivitySelection object immediately after it's returned by FamilyActivityPicker in the main app, the application.bundleIdentifier property is consistently nil for every Application object within selection.applications. Similarly, category.localizedDisplayName is nil for ActivityCategory objects. This happens whether Select All Apps is used or if apps/categories are selected individually. I understand that this is the intended behavior due to Apple's user privacy policies. I read on another post that my app can be provided with bundle identifiers and app names within Shield Configurati

FamilyControls App Blocking Not Working for External TestFlight Testers
Hi everyone, I'm following up on this post I made earlier about an issue I'm having with FamilyControls and the DeviceActivityMonitor extension not working for external TestFlight testers. To briefly recap: I have official Apple approval for the com.apple.developer.family-controls entitlement (distribution) The entitlement is added to both my main app and the DeviceActivityMonitor extension The App Group is correctly configured for both targets On internal TestFlight builds, everything works as expected: app blocking works, the extension runs, and selected apps are shielded. On external TestFlight builds, users get the Screen Time permission prompt, can select apps to block, but nothing is blocked. Since that post, I submitted a Code Level Support request, and Apple asked me to file a bug report via Feedback Assistant. I did that almost a month ago. The only reply I’ve received since is that they can’t give a timeframe or guarantee it will be resolved. I'm stuck in limbo with no updates and
