I have created an iOS Share Extension, and am returning a simple NSItemProvider:

    let item = NSItemProvider(item: "A Response" as NSSecureCoding, typeIdentifier: kUTTypeText as String)  
    let extensionItem = NSExtensionItem()  
    extensionItem.attachments = [item]  

    self.extensionContext!.completeRequest(returningItems: [extensionItem], completionHandler: nil)  
But in the host app, in the completionWithItemsHandler, completed is true, yet, returnedItems is nil.

    activityController.completionWithItemsHandler = { (activity, completed, items, error) in  

        print("\(items?.count)")  

    }  
Yet, returning the exact same response in an Action Extension, the result reached the host app.

Does a Share Extension not send its response back to the host app? The docs would suggest otherwise: https://developer.apple.com/library/content/documentation/General/Conceptual/ExtensibilityPG/Share.html#//apple_ref/doc/uid/TP40014214-CH12-SW1
