Unescaped control character around character 981.Error while parsing JSON

Question

Error Domain=NSCocoaErrorDomain Code=3840 "Unescaped control character
around character 981." UserInfo={NSDebugDescription=Unescaped control
character around character 981.}

I am getting the above error in response to a request.

Below are the lines of code:

Alamofire.request(.POST, urlStr, parameters: parameter, encoding: .JSON, headers: nil).validate().responseJSON {
    response in switch response.result {

        case .Success(let JSON):
            completionHandler(JSON as! NSDictionary)

        case.Failure(let Error):

            print(Error)
    }
}

It gives a JSON response in Postman.

The response which is I am getting in Postman:

Answer 1

As per you were told, there is a problem related to "\n".

So I suggest you can add "" which will work for you, like below:

"\n"=> "\\n"

Because this is a special character called a backspace character.
