# init(fetchRequest:sectionIdentifier:transaction:) Creates a fully configured sectioned fetch request that uses the specified transaction when updating results. ``` @MainActor @preconcurrency init(fetchRequest: NSFetchRequest, sectionIdentifier: KeyPath, transaction: Transaction) ``` ## 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. `transaction` A transaction to use for user interface changes that result from changes to the fetched results. ## Discussion Use this initializer if you need a fetch request with updates that affect the user interface based on a [`Transaction`](/documentation/SwiftUI/Transaction). Otherwise, use [`init(fetchRequest:sectionIdentifier:animation:)`](/documentation/SwiftUI/SectionedFetchRequest/init(fetchRequest:sectionIdentifier:animation:)). --- Copyright © 2026 Apple Inc.
