Swift : Heart Rate (bpm) save into healthkit store

 private func saveHeartRateIntoHealthStore(height:Double) -> Void
    {
        // Save the user's heart rate into HealthKit.
        let heartRateUnit: HKUnit = HKUnit.countUnit().unitDividedByUnit(HKUnit.minuteUnit())
        let heartRateQuantity: HKQuantity = HKQuantity(unit: heartRateUnit, doubleValue: height)

        var heartRate : HKQuantityType = HKQuantityType.quantityTypeForIdentifier(HKQuantityTypeIdentifierHeartRate)
        let nowDate: NSDate = NSDate()

        let heartRateSample: HKQuantitySample = HKQuantitySample(type: heartRate
            , quantity: heartRateQuantity, startDate: nowDate, endDate: nowDate)

        let completion: ((Bool, NSError!) -> Void) = {
            (success, error) -> Void in

            if !success {
                println("An error occured saving the Heart Rate sample \(heartRateSample). In your app, try to handle this gracefully. The error was: \(error).")

                abort()
            }

        self.healthStore!.saveObject(heartRateSample, withCompletion: completion)

    }// end saveHeartRateIntoHealthStore
