init(entity:sectionIdentifier:sortDescriptors:predicate:animation:)
Creates a sectioned fetch request for a specified entity description, based on a section identifier, a predicate, and sort parameters.
Declaration
@MainActor @preconcurrency init(entity: NSEntityDescription, sectionIdentifier: KeyPath<Result, SectionIdentifier>, sortDescriptors: [NSSortDescriptor], predicate: NSPredicate? = nil, animation: Animation? = nil)Parameters
- entity:
The description of the Core Data entity to fetch.
- sectionIdentifier:
A key path that SwiftUI applies to the
Resulttype to get an object’s section identifier. - sortDescriptors:
An array of sort descriptors that define the sort order of the fetched results.
- predicate:
An Nspredicate instance that defines logical conditions used to filter the fetched results.
- animation:
The animation to use for user interface changes that result from changes to the fetched results.
Discussion
Use this initializer if you need to explicitly specify the entity type for the request. If you specify a placeholder Result type in the request declaration, use the init(sectionIdentifier:sortDescriptors:predicate:animation:) initializer to let the request infer the entity type. If you need more control over the fetch request configuration, use init(fetchRequest:sectionIdentifier:animation:).
