“DeviceActivityReport”

Hi, I’m using FamilyControls + DeviceActivity. Users select apps/categories/web domains via FamilyActivitySelection. I need to show today’s total usage for that selected group only, not the device’s full Screen Time. Setup: A visible DeviceActivityReport shows today’s per-app list with a daily DeviceActivityFilter for the selected tokens. This visible list is usually accurate and updates quickly. A separate hidden DeviceActivityReport uses the same filter to compute an aggregate total by summing app.totalActivityDuration in makeConfiguration(representing:). The extension sends that total to the main app via notify_set_state + Darwin notification. DeviceActivityMonitor is only used as a fallback. Problem: The visible app list stays current, but the aggregate total for the same selected apps sometimes lags by several minutes or updates only after new selected-app usage occurs. Sometimes the total appears temporarily frozen while the app list still looks correct. Questions: Is a hidden DeviceActivityReport

Since Monday March 13 2023, DeviceActivityReport with a daily segment filter shows 0 screen time, for all users of my app (there are thousands). When changing the segment to hourly, it works but performance suffers. I've defined the filter like this: @State private var filter = DeviceActivityFilter(segment: .daily(during: DateInterval( start: Calendar.current.startOfDay(for: .now), end: .now))) Is anybody else experiencing this? This happened on its own after no change in the code or update to the app, and seems to be correlated with the first full day of Daylight Savings. I will file a bug in Feedback Assistant, but is there any other guidance you can give on what might be the root cause, and if there's a fix? Seems like a large issue. Thanks in advance!

Hello, we had working DeviceActivityReport in our app for months now. However when building with Xcode 15 (previously betas, now the GM), the activity reports no longer displays anything on iOS 16 devices. If we run it with Xcode 14, it works. But with Xcode 15 builds, the device activity report only works on iOS 17 devices :( I am able to see some somewhat generic errors in the Console.app when opening screen that contains the report. -[_EXServiceClient launchWithConfiguration:error:]_block_invoke failed with error: Error Domain=com.apple.extensionKit.errorDomain Code=2 UserInfo={NSUnderlyingError=0x280b9b600 {Error Domain=RBSRequestErrorDomain Code=5 UserInfo={NSLocalizedFailureReason=}}} Failed to create extensionProcess for extension '' error: Error Domain=com.apple.extensionKit.errorDomain Code=2 UserInfo={NSUnderlyingError=0x280b9b600 {Error Domain=RBSRequestErrorDomain Code=5 UserInfo={NSLocalizedFailureReason=}}}.

Device: iPhone 15 Pro Max, iOS 26.4 Xcode: Latest version, development signing with Automatically manage signing Team: Registered Apple Developer Program (Organization) Problem DeviceActivityReport SwiftUI view renders completely blank. The Report Extension's makeConfiguration(representing:) is never called (confirmed via App Group counter that stays at 0). The DeviceActivityMonitorExtension callbacks (intervalDidStart, eventDidReachThreshold) also never fire. What works AuthorizationCenter.shared.requestAuthorization(for: .individual) → .approved DeviceActivityCenter().startMonitoring() → registers schedules successfully, center.activities returns them ManagedSettingsStore.shield.applications → blocks apps correctly from the main app process Screen Time is enabled and actively collecting data (Settings > Screen Time shows per-app usage: Clash Royale 2h 35m, etc.) App Group UserDefaults(suiteName:) read/write works from the main app What doesn't work DeviceActivityReportExtension.makeConfiguration

I’m building a rich Home surface around a DeviceActivityReport embedded in my host app, and I’ve hit a set of boundaries that I’d like to confirm as intended behavior rather than something I’m doing wrong. All results below are from physical devices running iOS 18 and iOS 26, since Screen Time data is not available in Simulator. What I’m trying to build I want a single scrolling page where: The host app owns some chrome, including a date picker, refresh button, and settings button. The embedded DeviceActivityReport renders the Screen Time data, including totals, a per-hour chart, and per-app usage. The host chrome can react to the report scrolling. Taps inside the report can open a full-screen sheet. Findings so far 1. Report → host App Group writes do not reach the host A UserDefaults(suiteName:) write, or a file written to the App Group container, from inside the report extension returns success. However, the host app reads nil for those keys, including for a plain string marker unrelated
