sectionIdentifier

The key path that the system uses to group fetched results into sections.

Declaration 宣言 

var sectionIdentifier: KeyPath<Result, SectionIdentifier> { get nonmutating set }

Discussion 議論

Set this value to cause the associated SectionedFetchRequest to execute a fetch with a new section identifier, producing an updated collection of results. Changing this value produces a new set of sections. Use care to coordinate section and sort updates, as described in SectionedFetchRequest.Configuration.
