Hey there! So, I'm trying to see what I'm able to do with the Device Activity Report Extension, and I have a few questions about the following quote: 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. In particular, what constitutes the address space for this extension? Can I save data to a UserDefaults object that only the extension can access? (Apps like Opal allow the user to label apps as "distracting" and "non-distracting", and I'm wondering how they do that!) From what I've read, I believe it cannot write to a shared app group or model (and I just want to confirm this) It also seems that there's nothing preventing it from reading data from the main app, so I'm just wondering if it's able to read data from an app group or model with no problem. Thanks in advance!

Here is a post to gather findings in case anyone found out what this new API does. Apple did not include any comments or documentation and due to the generic naming we don't know what this API might does. https://developer.apple.com/documentation/deviceactivity/deviceactivityauthorization?changes=latest_major

Hello, I am trying to create a Home Screen widget for iOS that displays device usage statistics — similar to the built-in Screen Time widget Apple provides. The goal is to show the average device usage for a specified period (daily, weekly, or monthly) and optionally include a comparison with the previous period. I noticed that Apple’s own Screen Time widget presents such information. However, after reviewing the public documentation, I could not find any available API that allows a developer to create a similar experience. To explore possible alternatives, I implemented a SwiftUI view inside a com.apple.deviceactivityui.report-extension using the Family Controls and Device Activity frameworks. The view works fine within the main app and the report extension context, but when I attempted to use the same view in a WidgetKit extension, I received an error at runtime. This suggests that views from com.apple.deviceactivityui.report-extension are not usable inside widgets, which I understand may be due to sandboxing or limitations of how the extension points are designed. So far, I’ve found no way to access cumulative or average usage data (screen time, app usage, etc.) from system APIs that can be shown in a widget context. My understanding is that Family Controls and Device Activity frameworks allow observing ongoing activity and building usage reports inside the app, but do not provide access to the same historical or summarized data that Apple’s own widgets display. Could you please confirm: Whether there is any supported way to access average device usage (screen time) data for use in a widget? If not, is this an intentional limitation due to privacy concerns, or is there a roadmap for exposing such APIs in the future? Are there any APIs or entitlements that could allow similar functionality via WidgetKit? Thank you for your time and support. Best regards,

I found that in iOS 18.5, DeviceActivityCenter startMonitoring cannot start multiple monitors, even if their names and periods are different, and restarting the phone cannot solve it. My app uses DeviceActivityCenter, which makes the entire function unusable. (I have less than 20 monitors)

Hi everyone, I’m experimenting with the new ScreenTime DeviceActivityReport view in SwiftUI (iOS 17 / Xcode 15). My goal is to show the report inside a Button (or, more generally, capture any tap on it) so that I can push a detail screen when the user selects it. Here’s the minimal code that reproduces the issue: import FamilyControls import DeviceActivity import SwiftUI struct ScreenTimeView: View { let center = AuthorizationCenter.shared @State private var context: DeviceActivityReport.Context = .init(rawValue: "Total Activity") @State private var filter = DeviceActivityFilter( segment: .hourly( during: Calendar.current.dateInterval(of: .day, for: .now)! ), users: .all, devices: .init([.iPhone, .iPad]) ) var body: some View { ZStack { DeviceActivityReport(context, filter: filter) } .onAppear { Task { do { try await center.requestAuthorization(for: .individual) } catch { print("Authorization failed:", error) } } } } } struct ContentView: View { var body: some View { ScrollViewReader { _ in ScrollView(showsIndicators: false) { VStack { Button { print("BUTTON TAPPED") // ← never fires } label: { ScreenTimeView() .frame(height: UIScreen.main.bounds.height * 1.4) } } } } } } ** What happens** DeviceActivityReport renders correctly with hourly bars. Tapping anywhere inside the Button does not trigger print("BUTTON TAPPED"). I’ve tried replacing Button with .onTapGesture, adding .contentShape(Rectangle()), and .allowsHitTesting(true), but nothing registers. What I’ve checked Authorisation succeeds—calling code in .onAppear prints no errors. Removing DeviceActivityReport and replacing it with a plain Rectangle() lets the tap gesture fire, so the issue seems specific to DeviceActivityReport.

Hello! I am a relatively new Apple developer and am almost done with my first app. I am implementing the Screen Time API to my app because the app is designed to help the user digitally detox and I am trying to make it so the user can select which apps they would like to monitor from a list of their apps on their phone so I am using the family activity picker but I just can't extract the data needed to track the apps. I am wondering how to do this. Thank you!

Hi, I have a released screentime app ScreenZen. The last few days I've seen a disturbing spike in bug reports coming from people with 17.4.1 and 17.5.1 phones with no update to the app itself. People reported they saw the issue immediately after updating their iOS version. Unfortunately it is not replicable on all phones with those versions, so we haven't been able to replicate it on our test phones. It appears the issue is the ApplicationToken passed into ShieldActionExtension and ShieldConfigurationExtension does not match any of the ApplicationTokens that the user selected to block through FamilyControls. (The selected ApplicationTokens are being loaded through a group UserDefaults and they are indeed being loaded in the ShieldActionExtension in the bug reports).This is preventing the app from loading the correct settings and handling the blocking accordingly. I am trying to isolate this better with a new release with better logging, but would appreciate any help on this issue.

Hi I'm trying to build a screen time app and the Apple docs and APIs really leave something to be desired. I want to block apps on a schedule. That's it. To do this I need my DeviceActivityMonitorExt to know which apps to block. I need to somehow pass a DeviceActivitySelection from the main app into this DeviceActivityMonitorExt. How can I do this?

How can I use the Screen Time API to set a restriction for a child account from my app running on the parent’s account?

I’m creating an app with the Screen Time API and I would like to know how to make the app show a parental control editing view for parents and a view for child accounts that shows which apps are blocked. How can I do this?

I created a ShieldConfigurationExtension in Xcode 14.3 with File > New > Target > ShieldConfigurationExtension. This created the extension with all the necessary Info.plist values (correct NSExtensionPrincipalClass, etc.), with the extension included in embedded content in the host app target. No matter what I try, the extension is not getting invoked when I shield applications from my host app. The custom UI does not show as the shield, and looking at the debugger, an extension process is never invoked. I am shielding categories like this: let managedSettings = ManagedSettingsStore() ... managedSettings.shield.applicationCategories = .all() And my extension code overrides all the ShieldConfigurationDataSource functions. class ShieldConfigurationExtension: ShieldConfigurationDataSource { override func configuration(shielding application: Application) -> ShieldConfiguration { return ShieldConfiguration( backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial, backgroundColor: UIColor.white, icon: UIImage(systemName: "stopwatch"), title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow) ) } override func configuration(shielding application: Application, in category: ActivityCategory) -> ShieldConfiguration { return ShieldConfiguration( backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial, backgroundColor: UIColor.white, icon: UIImage(systemName: "stopwatch"), title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow) ) } override func configuration(shielding webDomain: WebDomain) -> ShieldConfiguration { return ShieldConfiguration( backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial, backgroundColor: UIColor.white, icon: UIImage(systemName: "stopwatch"), title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow) ) } override func configuration(shielding webDomain: WebDomain, in category: ActivityCategory) -> ShieldConfiguration { return ShieldConfiguration( backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial, backgroundColor: UIColor.white, icon: UIImage(systemName: "stopwatch"), title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow) ) } } What am I missing?
