DeviceActivityMonitor unreliable with iOS 17 - any other ways to schedule tasks?

We have an app that uses the Screen Time APIs to block certain apps set by the user on a schedule: We use ManagedSettings to shield selected apps We use DeviceActivityMonitor to shield the apps automatically on a schedule set by the user. The shielding starts during the intervalDidStart callback function and ends during the intervalDidEnd callback function We are getting reports from the majority of our iOS 17 users that the app blocking schedules no longer work on iOS 17. We have tested this on our own iOS 17 devices and reproduced the behavior. But the feature still works consistently on iOS 16 devices. The app is still built using Xcode 14 instead of Xcode 15 due to another issue - the DeviceActivityReport is blank for all iOS 16 users when built in Xcode 15 (link to issue on the developer forums: https://developer.apple.com/forums/thread/735915). When testing with Xcode 15 builds, the bug appears to improve - however it still occurs intermittently. Are there any other mechanisms to run tasks on r

Reply to Using core data in ShieldConfigurationExtension

I think it's quite likely that the sandbox is blocking access to Core Data. I'm using it via Swift Data: do { container = try ModelContainer( for: Settings.self, configurations: ModelConfiguration(allowsSave: allowsSave) ) context = ModelContext(container) } catch { fatalError(*** Failed to create BreakManager: (error)) } I get an error when I try to create the ModelContainer: Failed to register for com.apple.managedconfiguration.effectivesettingschanged: 9 Could not register for user invalidated notifications; status = 9 error: (3) access permission denied error: Encountered exception error during prepareSQL for SQL string 'SELECT TBL_NAME FROM SQLITE_MASTER WHERE TBL_NAME = 'Z_METADATA'' : access permission denied with userInfo { NSFilePath = /private/var/mobile/Containers/Shared/AppGroup//Library/Application Support/default.store; NSSQLiteErrorDomain = 3; } while checking table name from store: error: addPersistentStoreWithType:configuration:URL:options:error: returned error NSCocoaErrorDomain (256) error

Cannot get DeviceActivityReport to work

I am unable to make any progress regarding DeviceActivityReport. The session from WWDC 2022 covers it very briefly. What I (hopefully correctly) understood is that we need to create an extension of type Activity report and inside it implement the body which is DeviceActivityReportScene that will display the charts and what not. And then in the app, we need to use DeviceActivityReport with SwiftUI to show the report which will be run in sandbox from the extension. But I cannot get anything to show up on the screen. Even when my extension view is just a static text to verify something gets displayed. I am trying to create the device activity report without any filter which should give me all activity data per the docs. This is shown in the Xcode console for the view that uses DeviceActivityReport. 2022-06-17 18:08:47.219785+0200 DeviceActivityTest[9613:954204] [default] LaunchServices: store (null) or url (null) was nil: Error Domain=NSOSStatusErrorDomain Code=-54 process may not map

Reply to Cannot get DeviceActivityReport to work

At first, I got the same issue and the name of my extension was DeviceActivityReport. Then, I removed the extension and created a new extension named DeviceActivityReport. As a result, the issue disappeared!

Screen Time API is completely UNRELIABLE!

I've been working with the Screen Time API for almost 6 months now. I found out it's completely unreliable, testing on iOS 17.4, the DeviceActivityReport is not showing, the DeviceActivityMonitor more often than not does not fire intervalDidStart. It's very frustrating. Has anyone found out a workaround? We all know there has to be something we're doing wrong, since apps like Opal and Jono does not present those types of issues. Let's please unite our forces and find a solution. How to use this API should not be a secret!

How long is DeviceActivityData accessible in DeviceActivityReport?

Using the DeviceActivity framework we are able to display data based on a user's screentime and device usage. With the DeviceActivityFilter property, you can specify the date interval to collect data between. In testing, it seems that data only becomes accessible once the extension has been installed (so the extension isn't reading the screentime data already collected on device). However, once installed, I'm curious how far back you can query data from in the data interval? Opal which uses the Screentime API appears to have a lifetime Screentime metric, so hypothetically it should possible to query data as far back as collection starts. Unless they are getting around the sandbox environment and storing the data somehow. Side note on Opal -- They seem to have a community average of Screentime among people in the same age group. Does anyone know how they are collecting the data for this average? Is it actually using live Screentime data or just aggregating data from other studies?

Please help make DeviceActivityReport reliably show up

Our app uses DeviceActivityReport to display the user’s screen time. The performance of DeviceActivityReport is often very poor. These issue occur commonly: Screen time is reported as 0 minutes DeviceActivityReport View appears completely blank The host app loses connection with the DeviceActivityReport altogether I have implemented several workarounds which only slightly improve the performance, to varying degrees depending on the device iOS: Inside the DeviceActivityReport code - retry fetching screen time data until it returns a non-zero result Implement a “refresh” button which reloads the DeviceActivityReport view from the host app However, due to the sandboxed nature of DeviceActivityReport, there is no way for the host application to tell if the DeviceActivityReport extension is experiencing these performance issues. It results in a really bad user experience. I am building the app with Xcode 14 due to another issue where DeviceActivityReport

DeviceActivityReport based views are blank on iOS 16 whith apps built with Xcode 15 beta

Hi everyone ! Apple just announced that Xcode 15 will be mandatory to publish app updates starting April 2024 (https://developer.apple.com/ios/submit/) This is making this bug critical as we will have to drop iOS 16 if we want to update our apps containing DeviceActivityReport.

Reply to HELP ScreenTime API DeviceAcivityReport continious issues

@pravinu that's 100% impossible because Device Activity Report Extension is in the sandbox that can read data but can't write to any storage or make any network calls To protect the user’s privacy, your extension runs in a sandbox. This sandbox prevents your extension from making network requests or moving sensitive content outside the extension’s address space https://developer.apple.com/documentation/deviceactivity/deviceactivityreport

HELP ScreenTime API DeviceAcivityReport continious issues

Hi everyone, I've been spending my evenings on the app for around 6 months that's using Screen Time API introduced in WWDC 21 (https://developer.apple.com/videos/play/wwdc2021/10123/), I'm having many issues with this API and looking for anyone who has experience with this API, I will appreciate any help or advice I can get! I'm using DeviceActivityReport to display the dashboard with screen time usage and certain metrics. Device activity report extension runs in an isolated sandbox, which makes it harder to debug and can't make any network call or write to any storage, for privacy purposes which makes sense, but makes it very hard for development. The issue is that the process where DeviceActivityReport is running crashes for no reason frequently or doesn't run at all. The API itself has many bugs, which is backed up by my experience, Opal app developers and Screen Time even made the news with its bugs. I see the same behaviour with other apps like Opal, but they can workaround somehow it a
