I've setup screen time api with encouraged & discouraged apps and monitoring apps. var selectionToDiscourage = FamilyActivitySelection() { willSet { print ("got here \(newValue)") let applications = newValue.applicationTokens let categories = newValue.categoryTokens //let webCategories = newValue.webDomainTokens store.shield.applications = applications.isEmpty ? nil : applications store.shield.applicationCategories = ShieldSettings.ActivityCategoryPolicy.specific(categories, except: Set()) store.shield.webDomainCategories = ShieldSettings.ActivityCategoryPolicy.specific(categories, except: Set()) } } let events: [DeviceActivityEvent.Name: DeviceActivityEvent] = [ .encouraged: DeviceActivityEvent( applications: selectionToDiscourage.applicationTokens, threshold: DateComponents(minute: 10)) ] print ("Could not start monitoring \(selectionToDiscourage)") let center = DeviceActivityCenter() center.stopMonitoring() do { try center.startMonitoring(.daily, during: schedule, events: events) } catch { print ("Could not start monitoring \(error)") } extension DeviceActivityName { static let daily = Self("daily") } @available(iOS 15.0, *) extension DeviceActivityEvent.Name { static let encouraged = Self("encouraged") } ideally once the encouraged apps reaches 10mins screentime I should have received an event in DeviceActivityMonitorExtension. However i am not receiving any event here. super.eventDidReachThreshold(event, activity: activity) print("eventDidReachThreshold", event) store.shield.applications = nil store.shield.applicationCategories = nil // Handle the event reaching its threshold. } Please help.
