I am writing an action extension to transform an image URL and copy to clipboard by clicking the share button of an image on a webpage in Safari.

I created an action extension in Xcode without UI.

In javascript preprocessing script action.js, I can get the URL and title of the whole page.

    run: function(arguments) {
        
        arguments.completionFunction({
            "URL" : document.URL,
            "title": document.title
        })
    },

And that works for the share button of the whole webpage.

But how can I get the URL of the image that is pushed one?

When you use from URL, its better to use from :

  pod 'SDWebImage'

this is better because of cache

you can Set your URL string with below code:

libraryImageView.sd_setImage(with: URL(string: "your URL string"),
                                  placeholderImage: UIImage(named: Image.placeholder.rawValue))

after that you can get URL with below code:

libraryImageView.sd_ImageURL

Answering my own question. I had to create an action extension with User Interface so that I am working within ActionViewController: UIViewController class. The trick is to look for UTType.url.identifier through the shared items.

The code below works for share button of the whole webpage and an image.

    override func viewDidLoad() {
        super.viewDidLoad()
    
        // search for url
        var found = false
        for item in self.extensionContext!.inputItems as! [NSExtensionItem] {
            for provider in item.attachments! {
                if provider.hasItemConformingToTypeIdentifier(UTType.url.identifier) {
                    provider.loadItem(forTypeIdentifier: UTType.url.identifier, options: nil, completionHandler: { (url, error) in
                        OperationQueue.main.addOperation {
                                if let url = url as? URL {
                             
          // do something with the url here
                            
                       }

                    }})
                    
                    found = true
                    break
                }
            }
            
            if (found) {
                // We only handle one url, so stop looking for more.
                break
            }
        }

        // don't show user interface
        self.done()
    }
