If you need to download an image and then share you should do that separately, there is no single method that does that for you. Here is how:

func shareImageFromUrl(_ string: String) {

    guard let myUrl = URL(string: string) else {
        print("Invalid url!")
        return
    }

    URLSession.shared.dataTask(with: myUrl) { (data, _, _) in
        guard let data = data,
            let image = UIImage(data: data) else
        { return }

        let activityViewController:UIActivityViewController = UIActivityViewController(activityItems: [image], applicationActivities: nil)
        activityViewController.excludedActivityTypes = [UIActivity.ActivityType.print, UIActivity.ActivityType.postToWeibo, UIActivity.ActivityType.copyToPasteboard, UIActivity.ActivityType.addToReadingList, UIActivity.ActivityType.postToVimeo]
        DispatchQueue.main.async {
            self.present(activityViewController, animated: true, completion: nil)
        }
    }.resume()
}
