Answer 1

Finally I have done it :)

I changed the method like below and it Worked

func callRequestAPI(url:String){

    var configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    var session = NSURLSession(configuration: configuration)

    let params:[String: AnyObject] = [
        "product_id" : selectedUberProductId,
        "start_latitude" : start_lat,
        "start_longitude" : start_lng,
        "end_latitude" : end_lat,
        "end_longitude" : end_lng]



    let request = appDelegate.oauth.request(forURL: NSURL(string:url)!)
    request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
    request.HTTPMethod = "POST"
    var err: NSError?
    request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: NSJSONWritingOptions.allZeros, error: &err)

    let task = session.dataTaskWithRequest(request) {
        data, response, error in

        if let httpResponse = response as? NSHTTPURLResponse {
            if httpResponse.statusCode != 202 {
                println("response was not 202: \(response)")

                return
            }
        }
        if (error != nil) {
            println("error submitting request: \(error)")
            return
        }

        // handle the data of the successful response here
        var result = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.allZeros, error: nil) as! NSDictionary


        println(result)

        if let request_id: String = result["request_id"] as? String{

            println(request_id)
        }

        if let driver: String = result["driver"] as? String{

            println(driver)
        }

        if let eta: Int = result["eta"] as? Int{

            println(eta)
        }

        if let location: String = result["location"] as? String{

            println(location)
        }


        if let status: String = result["status"] as? String{

            println(status)
        }


        if let surge_multiplier: Int = result["surge_multiplier"] as? Int{

            println(surge_multiplier)
        }

        if let vehicle: String = result["vehicle"] as? String{

            println(vehicle)
        }

    }

    task.resume()

}

here is the Response I Got, Parsing is also given in my above method

{
  driver = "";
  eta = 15;
  location = "";
  "request_id" = "ea39493d-b718-429f-8710-00a34dcdaa93";
  status = processing;
  "surge_multiplier" = 1;
  vehicle = "";
}

Enjoy
