Alamofire 4 and special characters in JSON

Edit:

Alamofire.request(url, method: .get, parameters: param, encoding: JSONEncoding.default)        .responseJSON { response in            switch response.result {            case .success(let value) :                print(response.request)  // original URL request                print(response.response) // HTTP URL response                print(response.data)     // server data                print(response.result)   // result of response serialization                if let JSON = response.result.value as! [String:AnyObject]!{                    print("JSON: ",JSON)                    self.arrUser = Mapper<Users>().mapArray(JSONArray:JSON["user"] as! [[String : Any]])!                    self.tableView.reloadData()                }            case .failure(let encodingError):                //Print error            }    }

I got the issue that I have added æ in json response and try to print.

Output:

JSON:  Optional(<__NSArrayI 0x600000050320>({    "email_address" = "testwts06@gmail.com";     username = "testwts06 \U00e6";},{    "email_address" = "testwts01@gmail.com";    username = "testwts01 \U00eb";},{    "email_address" = "testwts100@gmail.com";    username = testwts100;})

While displaying it display in correct format.

Seems the typical serialization error due to wrong JSON encoding, probably your response status code is 3840.

JSON text SHALL be encoded in UTF-8, UTF-16, or UTF-32.

You could try to convert the response data to correct UTF8 encoding:

let datastring = NSString(data: response.data!, encoding: String.Encoding.isoLatin1.rawValue)let data = datastring!.data(using: String.Encoding.utf8.rawValue)do {     let object = try JSONSerialization.jsonObject(with: data!, options: .allowFragments)     let jsonDic = object as! NSDictionary     print("  ok, successfully converted..\(jsonDic)")} catch let aError as Error {     // print and handle aError }

Hope it helps you.

Swift 3 update for Ekta's answer:

let encodedURL = specificURL.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)
