# importDidFinish(completionHandler:) Tells the File Provider extension that the system finished importing items. ``` optional func importDidFinish(completionHandler: @escaping @Sendable () -> Void) ``` ## Parameters `completionHandler` A block that your implementation must call. ## Discussion > Important: > You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration: > > ```swift > optional func importDidFinish() async > ``` > > For information about concurrency and asynchronous code in Swift, see . The system calls this method after importing on-disk items. You can trigger an import by calling either [`reimportItems(below:completionHandler:)`](/documentation/FileProvider/NSFileProviderManager/reimportItems(below:completionHandler:)) or [`import(_:fromDirectoryAt:completionHandler:)`](/documentation/FileProvider/NSFileProviderManager/import(_:fromDirectoryAt:completionHandler:)). The system can also initiate its own imports as needed. During the import, the system calls your File Provider extension’s [`createItem(basedOn:fields:contents:options:request:completionHandler:)`](/documentation/FileProvider/NSFileProviderReplicatedExtension/createItem(basedOn:fields:contents:options:request:completionHandler:)) method and passes the [`mayAlreadyExist`](/documentation/FileProvider/NSFileProviderCreateItemOptions/mayAlreadyExist) option. Check to see if the item already exists in your remote storage—uploading it if necessary. After importing all the items, the system calls your [`importDidFinish(completionHandler:)`](/documentation/FileProvider/NSFileProviderReplicatedExtension/importDidFinish(completionHandler:)) method. Handle any necessary cleanup operations, and then call the completion handler. --- Copyright © 2026 Apple Inc.
