# recycle(_:completionHandler:) Moves the specified URLs to the trash in the same manner as the Finder. ``` func recycle(_ URLs: [URL], completionHandler handler: (@Sendable ([URL : URL], (any Error)?) -> Void)? = nil) ``` ## Parameters `URLs` An array of objects representing the files to move to the trash. This parameter must not be `nil` `handler` The completion handler block object to call when the operation completes. You may specify `nil` for this parameter. If this parameter is not `nil`, you must call the [`recycle(_:completionHandler:)`](/documentation/AppKit/NSWorkspace/recycle(_:completionHandler:)) method from a block running on an active dispatch queue; your completion handler block is subsequently executed on the same dispatch queue. The block takes two arguments: - newURLs: A dictionary that maps the file’s original location to its location in the trash. Each key is a URL from the `URLs` parameter. The value of each key is a URL representing the location of the file in the trash. If this method could not move a file to the trash, the corresponding URL is not included in the dictionary. - error: If the operation succeeded for every file, this parameter is `nil`. If the operation failed for one or more files, the parameter contains an error object describing the overall result of the operation in a manner suitable for presentation to the user. ## Discussion This method may cause a progress indicator, or other user interface element, to be shown by the Finder. In macOS 10.6, this method requires the app to run the main run loop in a common mode to facilitate the display of any user interface elements. You can safely call this method from any thread of your app. --- Copyright © 2026 Apple Inc.
