Accessing Website URL and Title in ShareExtension

I'm trying to access the url and title of the page the user is currently on via a ShareExtension to my app.

After setting everything up I can't seem to get the code inside the completionHandler to run.

        if let item = extensionContext?.inputItems.first as? NSExtensionItem {
        if let attachments = item.attachments as? [NSItemProvider] {

            for attachment: NSItemProvider in attachments {

                print(attachment)

                    attachment.loadItem(forTypeIdentifier: kUTTypePropertyList as String, options: nil, completionHandler: {(dict, error) in


                        let itemDictionary = dict as! NSDictionary
                        let javaScriptValues = itemDictionary[NSExtensionJavaScriptPreprocessingResultsKey] as! NSDictionary
                        print(javaScriptValues)
                    })

            }
        }
    }

Having dug deeper I know the code executes as far as the for loop. The attachment is of type PropertyList.

However the loadItem(forIdentifier:options:completionHandler:) method seems to never run, even more so the code inside it.

Has anyone encountered this issue? I'm sure I'm missing something but cannot figure it out.

Change your "loadItem" to "loadItemAsync" and run it that way. I ran into literally the EXACT same problem of the completion block not running, but when I call "loadItemAsync" instead of just "loadItem," it runs fine and I get all the output from my JS file.
