completeRequest(returningItems:completionHandler:)

Tells the host app to complete the app extension request with an array of result items.

Declaration

func completeRequest(returningItems items: [Any]?, completionHandler: (@Sendable (Bool) -> Void)? = nil)

items:
An array of result items, each an 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 True 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 True, 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.

Calling this method eventually dismisses the app extension’s view controller.
