Swift3.0

Info.plistにNSHealthUpdateUsageDescriptionとNSHealthShareUsageDescriptionを追加します

※ Capabilities -> HealthKit をONにしてください。

2.xと3.xの差分

• HealthKitの定数が列挙体に変更
  • 例 : HKCharacteristicTypeIdentifierDateOfBirth → HKCharacteristicTypeIdentifier.dateOfBirth
• HKObjectType.characteristicTypeForIdentifier(String)からHKObjectType.characteristicType(forIdentifier: HKCharacteristicTypeIdentifier)に変更
• HKHealthStore.requestAuthorizationToShareTypes(Set<HKSampleType>?, readTypes: Set<HKObjectType>?, completion: (Bool, NSError?) -> Void)からHKHealthStore.requestAuthorization(toShare: Set<HKSampleType>?, read: Set<HKObjectType>?, completion: (Bool, Error?) -> Void)に変更
