I'm looking for a way to check user Screen Time and trigger a notification after a specified amount of time on certain apps. I have the code from WWDC21 but I was wondering if I could get the code sample for the Worklog app created for WWDC22.
Would really help as a reference point for building my project.
Thank you!

I am trying to configure my app to monitor device screen time and shield apps after a certain amount of screen time is reached.
Here's the scheduled I created:
let schedule = DeviceActivitySchedule(
// I've set my schedule to start and end at midnight
intervalStart: DateComponents(hour: 0, minute: 0),
intervalEnd: DateComponents(hour: 23, minute: 59),
// I've also set the schedule to repeat
repeats: true
)
class MySchedule {
var item: NoteItem
init(item: NoteItem) {
self.item = item
}
public func setSchedule() {
print("Setting schedule...")
print("Hour is: ", Calendar.current.dateComponents([.hour, .minute], from: Date()).hour!)
var threshold = DateComponents(hour: item.hour, minute: item.min)
let events: [DeviceActivityEvent.Name: DeviceActivityEvent] = [
.discouraged: DeviceActivityEvent(
applications: NotificationsModel.shared.selectionToDiscourage.applicationTokens,
threshold: threshold
)
]
let center = DeviceActivityCenter()
do {
print("Try to start monitoring...")
try center.startMonitoring(.daily, during: schedule, events: events)
} catch {
print("Error monitoring schedule: ", error)
}
}
And here's the shield set up I am currently using:
func setShieldRestrictions() {
let applications = NotificationsModel.shared.selectionToDiscourage
store.shield.applications = applications.applicationTokens.isEmpty ? nil : applications.applicationTokens
store.shield.applicationCategories = applications.categoryTokens.isEmpty
? nil
: ShieldSettings.ActivityCategoryPolicy.specific(applications.categoryTokens)
}
Currently my shield restrictions are set up so that they are enabled as soon as the user selects which apps they would like to be shielded. Is there a way to reverse that action so that they are only shielded after reaching their threshold for screen time?
The documentation for eventDidReachThreshold is sparse.
