How to get the image URL from LPLinkMetadata in Swift

Question

I am trying to get the URL for the image associated with a given URL. Using Apple's LPLinkMetadata, I am able to get the URL's title and description, but I cannot figure out how to access the metadata's image URL. I have access to data.imageProvider but I am not sure how to use it.

import LinkPresentation

final class URLHelper {

    @available(iOS 13.0, *)
    static func fetchURLPreview(url: URL) {

        let metadataProvider = LPMetadataProvider()

        metadataProvider.startFetchingMetadata(for: url) { (metadata, error) in

            DispatchQueue.main.async {

                if let _ = error {
                    // handle error
                } else if let data = metadata {
                    let urlTitle = data.title
                    let urlImageUrl = data.????????
                }
            }
        }
    }
}

Check below my code for get image URL from LPLinkMetadata.

let metadataProvider = LPMetadataProvider()
let url = URL(string: "https://www.facebook.com/")!
    
    metadataProvider.startFetchingMetadata(for: url) { metadata, error in
      if error != nil {
        return
      }
    
      metadata?.imageProvider?.loadFileRepresentation(forTypeIdentifier: kUTTypeImage as String, completionHandler: { (url, imageProviderError) in
                if imageProviderError != nil {
                    return
                }
                let myImage = UIImage(contentsOfFile: (url?.path)!)
            })
    
       }

Can you post full code to do this? i am not getting this to work properly... complaining about myImage not being used. – AndiAna Mar 01 '21 at 18:06
You are getting UIImage. Not the URL of the image. – Kevv Keka Jun 14 '23 at 23:03

let _ = md.imageProvider?.loadObject(ofClass: UIImage.self, completionHandler: { image, err in
                            DispatchQueue.main.async {
                                self?.imageViewWebSite.image = image as? UIImage
                            }
                        })
