                let headerTitle = try doc.title()

                try! undesiredElements?.remove()
               // print("Header title: \(headerTitle)")
                print("Header body: \(body)")
            } 
         

How to do this with swift soup

Try this code - :

 do {
                let doc: Document = try SwiftSoup.parse(html)
                let size = try doc.getElementsByClass("_53mw").first()
                let data = try size?.attr("data-store")
                print(data!)
                let videoUrl = convertToDictionary(text: data!)
                let url = videoUrl!["src"] as! String
                print(url)
            

            } catch Exception.Error(let type, let message) {
                print("Message: \(message)")
            } catch {
                print("error")
            }
