在SWIFTUI中显示HTML文本时检测到AttributeGraph

我尝试了以下代码并得到警告:

=== AttributeGraph: cycle detected through attribute 682680 ===

扩大

extension Data {
    var html2AttributedString: NSAttributedString? {
        do {
            return try NSAttributedString(data: self, options: [.documentType: NSAttributedString.DocumentType.html, .characterEncoding: String.Encoding.utf8.rawValue], documentAttributes: nil)
        } catch {
            print("error:", error)
            return  nil
        }
    }
    var html2String: String { html2AttributedString?.string ?? "" }
}

extension StringProtocol {
    var html2AttributedString: NSAttributedString? {
        Data(utf8).html2AttributedString
    }
    var html2String: String {
        self.html2AttributedString?.string ?? ""
    }
}

swiftui:

description = "<p class=\"uitk-flex-item uitk-flex-basis-full_wi......."
Text(description.html2String)

我不明白为什么会发出警告,因为在发出警告后,我的代码行为非常奇怪。有人有Idae吗?
