HKStatisticsCollectionQueryDescriptor

anchorDate

get anchorDate(): globalThis.Date

var anchorDate: Date

The anchor date for the resulting collection’s time intervals.

anchorDate

set anchorDate(value: globalThis.Date)

var anchorDate: Date

The anchor date for the resulting collection’s time intervals.

intervalComponents

get intervalComponents(): _Foundation_DateComponents

var intervalComponents: DateComponents

The date components that define the time interval for each statistics object in the resulting collection.

intervalComponents

set intervalComponents(value: _Foundation_DateComponents)

var intervalComponents: DateComponents

The date components that define the time interval for each statistics object in the resulting collection.

result

result(healthStore: HKHealthStore): Promise<HKStatisticsCollection>

func result(for healthStore: HKHealthStore) async throws -> HKStatisticsCollection

Returns the collection of statistics matching the receiver.

options

get options(): HKStatisticsOptions

var options: HKStatisticsOptions

The options indicating which types of statistics to compute.

options

set options(value: HKStatisticsOptions)

var options: HKStatisticsOptions

The options indicating which types of statistics to compute.

results

results(healthStore: HKHealthStore): HKStatisticsCollectionQueryDescriptor_Results

func results(for healthStore: HKHealthStore) -> HKStatisticsCollectionQueryDescriptor.Results

Returns an `AsyncSequence` representing a stream of changes to the statistics collection matching the receiver. The first element will reflect the current state of the statistics collection. Subsequent elements will be yielded to reflect changes to the collection. When possible, the `updateStatistics` property will be populated to indicate the specific statistics that have changed.

init

static init(predicate: HKSamplePredicate<HKQuantitySample>, options: HKStatisticsOptions, anchorDate: globalThis.Date, intervalComponents: _Foundation_DateComponents): HKStatisticsCollectionQueryDescriptor

init(predicate: HKSamplePredicate<HKQuantitySample>, options: HKStatisticsOptions, anchorDate: Date, intervalComponents: DateComponents)

predicate

get predicate(): HKSamplePredicate<HKQuantitySample>

var predicate: HKSamplePredicate<HKQuantitySample>

The predicate matching the samples to compute statistics over.

predicate

set predicate(value: HKSamplePredicate<HKQuantitySample>)

var predicate: HKSamplePredicate<HKQuantitySample>

The predicate matching the samples to compute statistics over.
