How to show file size and type in UIActivityViewController modal

Question

To allow the user to download a file, I use the UIActivityViewController provided by Apple. The following code produces the first screenshot:

let url: URL = // some url
let activityViewController = UIActivityViewController(activityItems: [url, "A filename"], applicationActivities: nil)
present(activityViewController, animated: true, completion: nil)

However, it does not show the file type (pdf document) and size, as is shown in the screenshot below. All functions of the activity view work (downloading, mailing, etc).

Does anyone know how this information can be displayed using a UIActivityViewController ?
