  "methodology": "Every identifier in HealthKit's four naming families — HKQuantityTypeIdentifier, HKCategoryTypeIdentifier, HKCharacteristicTypeIdentifier and HKWorkoutActivityType — read on 2026-08-28 from the JSON Apple serves to render developer.apple.com. The identifier, Objective-C constant, group, abstract and platform versions are copied from Apple's payload unchanged. Two columns are DERIVED because Apple states them only in prose and not as machine-readable properties: aggregation (cumulative vs discrete) and unitFamily. Both are matched literally against Apple's own sentences — \"measure cumulative values\", \"use energy units\" — and are null where Apple's wording does not state them, never guessed. Both apply ONLY to quantity types: for the other three families they are null because the concept does not exist, not because Apple declined to state it — read them together with the family column. Aggregation is included because it determines whether HKStatisticsQuery should use .cumulativeSum or a discrete option, and choosing wrong returns a plausible wrong number rather than an error. valueEnum names the HKCategoryValue enum that decodes a category sample, which is null for every other family. Apple's abstracts are reproduced for identification of the API surface; the analysis and the aggregation classification are this site's.",
