Trying to schedule a notification based on the caloriesBurned only if they are less than a certain amount (with query to the health store) about carekit

You might want to consider using the HealthKit linked tasks in CareKit. The task can be scheduled to occur every day, and will pull data from HealthKit to populate its outcome. The scheduling logic might look something like this:

func createCalorieTask() -> OCKHealthKitTask {

    let calorieLinkage = OCKHealthKitLinkage(
        quantityIdentifier: .activeEnergyBurned,
        quantityType: .cumulative,
        unit: .kilocalorie()
    )

    let startOfDay = Calendar.current.startOfDay(for: Date())

    let dailySchedule = OCKScheduleElement(
        start: startOfDay,
        end: nil,
        interval: DateComponents(day: 1),
        duration: .allDay,
        targetValues: [OCKOutcomeValue(300)]
    )

    let calorieTask = OCKHealthKitTask(
        id: "calories",
        title: "Burn Calories",
        carePlanUUID: nil,
        schedule: OCKSchedule(composing: [dailySchedule]),
        healthKitLinkage: calorieLinkage
    )

    return calorieTask
}

Now in terms of scheduling a notification, you can choose to either schedule or "unschedule" that 8PM notification whenever the outcome for the task changes.

var query = OCKEventQuery(for: anIntervalEncompassingAFewEvents)
query.taskIDs = ["calories"]

for events in store.anyEvents(matching: query) {

    // schedule or unschedule notifications based on the
    // progress for each event
}

Hi, thank you for your response. However I still have problems with the notification, since OCKEventQuery doesn't have a member taskIDs

I have problem with the schedule of this task you provided, and I'm struggling to understand how should I use to "schedule and unschedule" the notification based on the calories burned during the day

Which branch of CareKit are you using? The main branch should have that property.

What problem are you running into?

You can begin by checking the progress for an event. If the progress is not completed, schedule a notification for 8PM. If the progress is completed, remove the 8PM notification.

`func createCalorieTask() -> OCKHealthKitTask {

let calorieLinkage = OCKHealthKitLinkage(
    quantityIdentifier: .activeEnergyBurned,
    quantityType: .cumulative,
    unit: .kilocalorie()
)

let startOfDay = Calendar.current.startOfDay(for: Date())

let dailySchedule = OCKScheduleElement(
    start: startOfDay,
    end: nil,
    interval: DateComponents(day: 1),
    duration: .allDay,
    targetValues: [OCKOutcomeValue(300)]
)

let calorieTask = OCKHealthKitTask(
    id: "calories",
    title: "Burn Calories",
    carePlanUUID: nil,
    schedule: OCKSchedule(composing: [dailySchedule]),
    healthKitLinkage: calorieLinkage
)

return calorieTask

}`
this task should be added to the healthkitstore right? And how do I check the progress to schedule the notification? and the OCKEventQuery(for: anIntervalEncompassingAFewEvents) gives me problem, too

it must be 2.1 version

[gavirawson-apple]

Yep! The OCKHealthKitPassthroughStore or an OCKStoreCoordinator.

And how do I check the progress to schedule the notification?

On 2.1, fetch the event for the task and check to see if the outcome value matches the target value for the schedule (which looks to be 300 calories based on the snippet above). To check compare those two, see OCKAnyEvent.outcome and OCKAnyEvent.scheduleEvent

OCKEventQuery(for: anIntervalEncompassingAFewEvents) gives me problem

That initializer expects a single date, not a date interval. You can use this initializer instead - OCKEventQuery(dateInterval:)
