Instance Property インスタンスプロパティ

sortDescriptors

The request’s sort descriptors, accessed as value types.

Declaration 宣言 

var sortDescriptors: [SortDescriptor<Result>] { get nonmutating set }
Available when SectionIdentifier conforms to Hashable and Result inherits NSManagedObject.

Discussion 議論

Set this value to cause the associated SectionedFetchRequest to execute a fetch with a new collection of SortDescriptor instances. The order of entities stored in the results collection may change as a result. Use care to coordinate section and sort updates, as described in SectionedFetchRequest.Configuration.

If you want to use NSSortDescriptor instances, set nsSortDescriptors instead.
