HKWorkout Rawdata 분석하기 (수영을 중심으로)

Heon Ha 2023. 7. 6.

수영앱을 만들면서 데이터를 쿼리한 결과를 가공하기 위한 데이터 분석

우선 지금까지 수영 기록중에서 가장 최근 데이터를 뽑아서 Rawdata를 분석해보았다.

HKWorkout

https://developer.apple.com/documentation/healthkit/hkworkout

 

HKWorkout | Apple Developer Documentation

A workout sample that stores information about a single physical activity.

developer.apple.com

 

// record는 [HKWorkout]타입

print("-------------------------------")
print("SWIM! Swimming Data를 가져왔습니다. \\(records)")
print("-------------------------------")
print("SWIM DEBUG duration: \\(records[0].duration)")
if #available(iOS 16.0, *) {
    print("SWIM! allStatistics: \\(records[0].allStatistics)")
    print("SWIM! workoutActivities: \\(records[0].workoutActivities)")
}
print("SWIM DEBUG workoutActivityType: \\(records[0].workoutActivityType)")
print("SWIM DEBUG workoutEvents: \\(records[0].workoutEvents)")

HKWorkout.duration

 

duration | Apple Developer Documentation

The workout’s duration.

developer.apple.com

 

 

duration: 총 운동 시간을 나타냄 (단위: Second)

duration: 3254.731590986252 // 약 54분

 

 

HKWorkout.allStatistics (iOS 16+)

 

allStatistics | Apple Developer Documentation

A dictionary that contains all the statistics for the workout builder.

developer.apple.com

var allStatistics: [HKQuantityType : HKStatistics] { get }

데이터를 Dictionary형태로 나타냄. iOS 16이상.

수영 데이터에서는 RawData를 보아서는 수영거리, 스트로크 횟수, 휴식에너지, 활동에너지를 확인 할 수 있음.

아래 네가지 데이터타입을 받아서 사용하면 될 것으로 판단 됨.

workoutActivityType: HKWorkoutActivityType(rawValue: 46)

 

 

HKWorkout.workoutEvents

workoutEvents | Apple Developer Documentation

 

workoutEvents | Apple Developer Documentation

An array of workout event objects.

HKWorkout.duration

duration | Apple Developer Documentation

duration: 총 운동 시간을 나타냄 (단위: Second)

duration: 3254.731590986252 // 약 54분

HKWorkout.allStatistics

allStatistics | Apple Developer Documentation

var allStatistics: [HKQuantityType : HKStatistics] { get }

데이터를 Dictionary형태로 나타냄. iOS 16이상.

수영 데이터에서는 RawData를 보아서는 수영거리, 스트로크 횟수, 휴식에너지, 활동에너지를 확인 할 수 있음.

아래 네가지 데이터타입을 받아서 사용하면 될 것으로 판단 됨.

HKWorkout

수영앱을 만들면서 데이터를 쿼리한 결과를 가공하기 위한 데이터 분석

우선 지금까지 수영 기록중에서 가장 최근 데이터를 뽑아서 Rawdata를 분석해보았다.

// record는 [HKWorkout]타입

print("-------------------------------")
print("SWIM! Swimming Data를 가져왔습니다. \\(records)")
print("-------------------------------")
print("SWIM DEBUG duration: \\(records[0].duration)")
if #available(iOS 16.0, *) {
    print("SWIM! allStatistics: \\(records[0].allStatistics)")
    print("SWIM! workoutActivities: \\(records[0].workoutActivities)")
}
print("SWIM DEBUG workoutActivityType: \\(records[0].workoutActivityType)")
print("SWIM DEBUG workoutEvents: \\(records[0].workoutEvents)")

HKWorkout.duration

duration | Apple Developer Documentation

duration: 총 운동 시간을 나타냄 (단위: Second)

duration: 3254.731590986252 // 약 54분

HKWorkout.allStatistics

allStatistics | Apple Developer Documentation

var allStatistics: [HKQuantityType : HKStatistics] { get }

데이터를 Dictionary형태로 나타냄. iOS 16이상.

수영 데이터에서는 RawData를 보아서는 수영거리, 스트로크 횟수, 휴식에너지, 활동에너지를 확인 할 수 있음.

아래 네가지 데이터타입을 받아서 사용하면 될 것으로 판단 됨.
