# init(sectionIdentifier:sortDescriptors:predicate:animation:) Creates a sectioned fetch request based on a section identifier, a predicate, and reference type sort parameters. ``` @MainActor @preconcurrency init(sectionIdentifier: KeyPath, sortDescriptors: [NSSortDescriptor], predicate: NSPredicate? = nil, animation: Animation? = nil) ``` ## Parameters `sectionIdentifier` A key path that SwiftUI applies to the `Result` type to get an object’s section identifier. `sortDescriptors` An array of sort descriptors that define the sort order of the fetched results. `predicate` An 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 The request gets the entity type from the `Result` instance by calling that managed object’s type method. If you need to specify the entity type explicitly, use the [`init(entity:sectionIdentifier:sortDescriptors:predicate:animation:)`](/documentation/SwiftUI/SectionedFetchRequest/init(entity:sectionIdentifier:sortDescriptors:predicate:animation:)) initializer instead. If you need more control over the fetch request configuration, use [`init(fetchRequest:sectionIdentifier:animation:)`](/documentation/SwiftUI/SectionedFetchRequest/init(fetchRequest:sectionIdentifier:animation:)). For value type sort descriptors, use [`init(sectionIdentifier:sortDescriptors:predicate:animation:)`](/documentation/SwiftUI/SectionedFetchRequest/init(sectionIdentifier:sortDescriptors:predicate:animation:)). --- Copyright © 2026 Apple Inc.
