Healthでの設定

誕生日・性別・血液型は公式AppであるHealthでしか登録ができないので、サンプルを動作させる前に登録します

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
• HKQuantityTypeIdentifierOxygenSaturationから``に変更
• HKHealthStore.dateOfBirthComponents()の利用推奨
