iOS Swift 2 - Alamofire print response value when Failure

I'm using Alamofire for my http requests but I'm not able to get error message from requests that don't pass validation

Alamofire.request(method, url, headers: headers, parameters: parameters, encoding: encoding)
            .validate(statusCode: 200..<300)
            .responseJSON { response in

                switch response.result {
                case .Success:
                    // response.result.value returns JSON

                case .Failure(let error):
                    // response.result.value returns nil
                }
        }

How can I get data (JSON) if I get error code 400 and others. The API is sending the data in body even if the request was not successful.

As Following SaiCYLi, Only way to get response data is avoid using validate.
See Result.swift in Alamofire.
There is blocker.

public var value: Value? {
    switch self {
    case .Success(let value):
        return value
    case .Failure:
        return nil
    }
}

I wanted comment to you instead of answering. But I have reputation less than 50. Sorry.

just delete your validation of status code

Code:

Alamofire.request(method, url, headers: headers, parameters: parameters, encoding: encoding)
      .responseJSON { 
      response in
            let statusCode = response.response.statusCode
            switch statusCode {
            case 200..<300:
                // Success
            case 404:
                // not found
            default: 
                // something else
            }
    }
