Part 3, Episode 16, Save body temperature into the HealthKit.

In this episode, I want to show you how to store data in the HealthKit.

static func addBodyTemperatureToHealthKit(temp: Double?, date: Date) {
    guard let quantityType = HKQuantityType.quantityType(forIdentifier: .bodyTemperature) else { return }
    guard let categoryType = HKObjectType.categoryType(forIdentifier: .fever) else { return }
    guard let temp = temp else { return }

    let quanitytUnit = HKUnit(from: "degC" )
    let quantityAmount = HKQuantity(unit: quanitytUnit, doubleValue: temp)
    let tempSample = HKQuantitySample(type: quantityType, quantity: quantityAmount, start: date, end: date)
    let feverSample = HKCategorySample(type: categoryType, value: Int((temp - 35 ) / 7.0 * 5), start: date, end: date)
    if HKHealthStore.isHealthDataAvailable() {
      let store = HKHealthStore()
      store.save([feverSample, tempSample]) { _, error in
        if error != nil {
          Logger.survey.error("Failed to write data to HK")
        }
      }
    }
  }
    SurveyViewModel.addBodyTemperatureToHealthKit(temp: feverValue.doubleValue, date: result.endDate)
