The key path to the sample’s quantity.


let HKPredicateKeyPathQuantity: String


Use this constant whenever you want to include a sample’s quantity in a predicate format string. Add a %K placeholder to the format string, and then pass this constant as an argument.

Alternatively, use the predicateForQuantitySamples(with:quantity:) method to create predicates that match a sample’s quantity.
