通过这样做解决了这个问题

let str = symbol
        if let htmldata = str.data(using: String.Encoding.utf8), let attributedString = try? NSAttributedString(data: htmldata, options: [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType], documentAttributes: nil)
        {
            let finalString = String(format: "%@",attributedString.string)
            return finalString
        }
        else
        {
            return ""
        }
