Status Codes

If you're working with an outside system which uses status codes (or error codes) to convey information, like HTTP Status Codes, enums are obviously a great way to encode the information. ¹

enum HttpError: String {

   case code400 = \"Bad Request\"

   case code401 = \"Unauthorized\"

   case code402 = \"Payment Required\"

   case code403 = \"Forbidden\"

   case code404 = \"Not Found\"

}
