# completeRequest(returningItems:completionHandler:) Tells the host app to complete the app extension request with an array of result items. ``` func completeRequest(returningItems items: [Any]?, completionHandler: (@Sendable (Bool) -> Void)? = nil) ``` ## Parameters `items` An array of result items, each an [`NSExtensionItem`](/documentation/Foundation/NSExtensionItem) object, to return to the host app. `completionHandler` An optional block to be called when the request completes, performed as a background priority task. The block takes the following parameter: - expired: A Boolean value that indicates whether the system is terminating a previous invocation of the `completionHandler` block. This parameter is when the system prematurely terminates a `completionHandler` block that was previously invoked and had not otherwise expired. > Important: > If the system calls your block with an `expired` value of , you must immediately suspend your app extension. If you fail to do this, the system terminates your extension’s process. > > When your app extension exits, all concurrent requests being handled by the extension, serving the same or other host apps, are terminated. ## Discussion Calling this method eventually dismisses the app extension’s view controller. --- Copyright © 2026 Apple Inc.
