2.xと3.xの差分
- HealthKitの定数が列挙体に変更
- 例 :
HKCharacteristicTypeIdentifierDateOfBirth→HKCharacteristicTypeIdentifier.dateOfBirth
- 例 :
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HKObjectType.quantityTypeForIdentifier(String)からHKObjectType.quantityType(forIdentifier: HKQuantityTypeIdentifier)に変更NSDateからDateに変更dispatch_async(dispatch_queue_t, dispatch_block_t)からDispatchQueue.main.async(execute: () -> Void)に変更HKHealthStore.executeQuery(HKQuery)からHKHealthStore.execute(HKQuery)に変更
