Swift 4 I have created a String extension

我已经创建了一个字符串扩展。

func utf8DecodedString()-> String {
     let data = self.data(using: .utf8)
     if let message = String(data: data!, encoding: .nonLossyASCII){
            return message
      }
      return ""
}

func utf8EncodedString()-> String {
     let messageData = self.data(using: .nonLossyASCII)
     let text = String(data: messageData!, encoding: .utf8)
     return text
}
