guard let attributedString = try? NSMutableAttributedString(
  data: data,
  options: [.documentType: NSAttributedString.DocumentType.html, .characterEncoding: String.Encoding.utf8.rawValue],
  documentAttributes: nil
  ) else {

don't put anything related with html on background thread and async process , html need lot of time to load and it on some case it will cause crash or dirty issue on NSMutableAttributedString
