DeviceActivityMonitor

I was able to start the device activity monitor. I was able to see the Device Activity Monitor Extension as a process, and was able to attach to it via Xcode. Now I am trying block a specific 3rd party application, via the Shield. I am using this piece of code for intervalDidStart : override func intervalDidStart(for activity: DeviceActivityName) { NSLog(Interval started for Device Activity) let blockedApps : Set = [Application(bundleIdentifier: com.facebook.Facebook)] store.application.blockedApplications = blockedApps super.intervalDidStart(for: activity) } I've declared store in the DeviceActivityMonitor class as follows : let store = ManagedSettingsStore() This is the error I see in the Console: Error Domain=UsageTrackingErrorDomain Code=1 Something without a application-identifier entitlement tried to manage usage budgets UserInfo={NSLocalizedDescription=Something without a application-identifier entitlement tried to manage usage budgets} The above use case should work right? I should be able to

I am writing an app of family controls and device settings. In the docs for DeviceActivityMonitor I read about the principal class of device activity monitor extension, so I have to implement it. But, in XCode there is no such extension. How do i create it?

I created my Device Activity Monitor extension, and then attempted to start monitoring using the code example from the video: let schedule = DeviceActivitySchedule( intervalStart: DateComponents(hour: 0, minute: 0), intervalEnd: DateComponents(hour: 23, minute: 59), repeats: true ) let center = DeviceActivityCenter() do { try center.startMonitoring(.daily, during: schedule) } catch { print(error) } The startMonitoring call always fails for me with the same error: [monitor] Failed to create UsageTrackingAgent proxy: Error Domain=NSCocoaErrorDomain Code=4099 The connection to service on pid 0 named com.apple.UsageTrackingAgent was invalidated. UserInfo={NSDebugDescription=The connection to service on pid 0 named com.apple.UsageTrackingAgent was invalidated.} Setting up the extension is a very manual process, so I likely missed a step somewhere, but any ideas on what this error might be indicating?

I am building an app that uses DeviceActivity framework. Looking at the documentation, I need to subclass (https://developer.apple.com/documentation/deviceactivity/deviceactivitymonitor), I need to subclass DeviceActivityMonitor and designate the subclass as the principal class of my app extension. I am wondering how to designate my subclass as the principal class. (I am new to iOS development :) .

Hello, I am wondering how to designate my DeviceActivityMonitor extension as the principal class on Xcode 13 beta 5 Documentation: https://developer.apple.com/documentation/deviceactivity/deviceactivitymonitor

i'm trying to make my app start blocking/shielding and app according to the selection from a familyActivityPicker. the problem that i'm having is that MyModel object is always nil when i'm accessing it inside the app extension. (DeviceActivityMonitor). can someone give me an example of the object he uses to get the applicationTokens in the app extension? an explanation on how to transfer information between the app and the app extension is also welcome.

i'm trying to shield and block apps on child device. i managed to block apps by creating a variable blockedApps : Set = Set() that contains a list of applications like Application(bundleIdentifier: com.apple.calculator) inside the intervalDidStart on my DeviceActivityMonitor extension now i'm trying to shield an app using the same extension and nothing happens. for this i used this code inside intervalDidStart: let calculatorApp = Application(bundleIdentifier: com.apple.calculator) var blockedApps : Set = Set() guard let token = calculatorApp.token else { return } blockedApps = [token] store.shield.applications = blockedApps and i cant tell what is the reason for this not working is there a token issue that is nil? does shielding requires a different app extension? does my app extension requires some additional configuration maybe a different NSExtensionPointIdentifier?

I've been working on a small app using the new FamilyControls API, and I can't get the extension to make any visible changes to shields (or anything else). I can get the main app to authorize and set and remove shields reliably. I can also get the extension to run reliably in the background on a schedule (confirmed with Console). But even if I try only setting the restricted apps to nil or the empty set the apps remain shielded until I run the same code from the main app. I do have the Family Controls entitlement set on both the app and the extension, and I've tried having it off on the extension. I have tried putting both of them into an App Group to no effect. I've wrapped up the most basic working example I can think of into a project: https://github.com/dpowers/ScreenPact Any ideas about what stupid thing I'm missing?

Hi all, I am facing a problem following the code in the Meet the Screen Time API video. I've tried scheduling the monitoring time from 00:00 to 25:59 or some other time but functions in DeviceActivityMonitor are never being called. I tried to print log from those functions, nothing shown. Is there any settings I've missed? In addition, I already changed the NSExtensionPrincipalClass value to my class name. Any help would be appreciated!
