For those who are trying to do this from viewDidLoad, you need to set a small timer, otherwise it won't work:

You should end your sharing extensions work with one of these two calls:

self.extensionContext!.completeRequestReturningItems(nil, completionHandler: nil)

self.extensionContext!.cancelRequestWithError(NSError())

Apples share extension docs

updated for swift 4:

self.extensionContext!.completeRequest(returningItems: nil, completionHandler: nil)

self.extensionContext!.cancelRequest(withError:NSError())
