SiwiftUI：UITextView 正在切换到 TextKit 1

我收到日志消息UITextView 正在切换到 TextKit 1 兼容模式，因为它的 textStorage 包含与NSAttributedString使用的TextKit 2 不兼容的属性。documentType: NSAttributedString.DocumentType.html

例子：

func makeUIView(context: Context) -> UITextView {
    let textView = UITextView()
    return textView
}

func updateUIView(_ uiView: UITextView, context _: Context) {
    var currentText: NSAttributedString?
    let htmlString = "<html><body><h1>Example</h1></body></html>"
    
    guard let encodedData = htmlString.data(using: .utf8) else {
        fatalError("Could not encode HTML data")
    }
    
    do {
        currentText = try NSAttributedString(data: encodedData,
                                             options: [
                                                .documentType: NSAttributedString.DocumentType.html,
                                                .characterEncoding: String.Encoding.utf8.rawValue
                                             ],
                                             documentAttributes: nil)
    } catch let error as NSError {
        fatalError(error.localizedDescription)
    } …
