“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=}}}. Failed to make extensionProcess with error: Error Domain=com.apple.extensionKit

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
