# init(fetchRequest:sectionIdentifier:animation:) Creates a fully configured sectioned fetch request that uses the specified animation when updating results. ``` @MainActor @preconcurrency init(fetchRequest: NSFetchRequest, sectionIdentifier: KeyPath, animation: Animation? = nil) ``` ## Parameters `fetchRequest` An instance that describes the search criteria for retrieving data from the persistent store. `sectionIdentifier` A key path that SwiftUI applies to the `Result` type to get an object’s section identifier. `animation` The animation to use for user interface changes that result from changes to the fetched results. ## Discussion Use this initializer when you want to configure a fetch request with more than a predicate and sort descriptors. For example, you can vend a request from a `Quake` managed object that the sample code project defines to store earthquake data. Limit the number of results to `1000` by setting a for the request: ``` extension Quake { var request: NSFetchRequest { let request = NSFetchRequest(entityName: "Quake") request.sortDescriptors = [ NSSortDescriptor( keyPath: \Quake.time, ascending: true)] request.fetchLimit = 1000 return request } } ``` Use the request to define a `SectionedFetchedResults` property: ``` @SectionedFetchRequest( fetchRequest: Quake.request, sectionIdentifier: \.day) private var quakes: FetchedResults ``` If you only need to configure the request’s section identifier, predicate, and sort descriptors, use [`init(sectionIdentifier:sortDescriptors:predicate:animation:)`](/documentation/SwiftUI/SectionedFetchRequest/init(sectionIdentifier:sortDescriptors:predicate:animation:)) instead. If you need to specify a [`Transaction`](/documentation/SwiftUI/Transaction) rather than an optional [`Animation`](/documentation/SwiftUI/Animation), use [`init(fetchRequest:sectionIdentifier:transaction:)`](/documentation/SwiftUI/SectionedFetchRequest/init(fetchRequest:sectionIdentifier:transaction:)). --- Copyright © 2026 Apple Inc.
