如何在SwiftUI中显示HTML文本

struct HTMLTextView: UIViewRepresentable {
    var htmlText: String
    
    func makeUIView(context: Context) -> UITextView {
        let textView = UITextView()
        textView.isEditable = false
        return textView
    }
    
    func updateUIView(_ uiView: UITextView, context: Context) {
        if let attributedString = htmlText.htmlToAttributedString {
            uiView.attributedText = attributedString
        } else {
            uiView.attributedText = NSAttributedString(string: htmlText)
        }
    }
}

extension String {
    var htmlToAttributedString: NSAttributedString? {
        guard let data = data(using: .utf8) else { return nil }
        do {
            return try NSAttributedString(data: data, options: [.documentType: NSAttributedString.DocumentType.html, .characterEncoding: String.Encoding.utf8.rawValue], documentAttributes: nil)
        } catch {
            return nil
        }
    }
}

struct ContentView: View {
    var body: some View {
        HTMLTextView(htmlText: "<h1>Hello, <i>World!</i></h1>")
    }
}
