I have a problem that I explain, I think I found a way to call the methods that are on the server, however when I call a method that has parameters, I get an error, and when I call a method that has no parameters okay. Can someone explain to me why this is happening or what I am doing wrong?

Service call code

statusCode should be 200, but is 500
resposta do servidor ******** = Optional(<NSHTTPURLResponse: 0x7fc90a626350> { URL: https://*****.*****.com/****.slet request = NSMutableURLRequest(URL: NSURL(string: "https://*****.*****.com/****.svc/rest/ListRules")!)  
        request.HTTPMethod = "POST"

        let postString = "ID=10"    
        request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
        let task = NSURLSession.sharedSession().dataTaskWithRequest(request) { data, response, error in
            guard error == nil && data != nil else {                                                          // check for fundamental networking error
                print("error=\(error)")
                return
            }

            if let httpStatus = response as? NSHTTPURLResponse where httpStatus.statusCode != 200 {           // check for http errors
                print("statusCode should be 200, but is \(httpStatus.statusCode)")
                print("resposta do servidor ******** = \(response)")
            }

            let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)
            print("responseString ++++++++++++ = \(responseString)")
        }
        task.resume()

The error I get is as follows:

vc/rest/ListRules} { status code: 500, headers {
    "Cache-Control" = private;
    "Content-Length" = 1937;
    "Content-Type" = "application/xml; charset=utf-8";
    Date = "Wed, 27 Jan 2016 10:39:58 GMT";
    Server = "Microsoft-IIS/8.5";
    "X-AspNet-Version" = "4.0.30319";
    "X-Powered-By" = "ASP.NET";
} })
responseString ++++++++++++ = Optional(<Fault xmlns="http://schemas.microsoft.com/ws/2005/05/envelope/none"><Code>

Code that will solve the problem however I am having an error passing the function parameter

let request = NSMutableURLRequest(URL: NSURL(string: "https://*******.*******.com/******.***/***/METODO")!) request.HTTPMethod = "POST"
var postString:NSString = "ID=23"  //--> ERRO?

I was able to solve my problem and the solution is as follows:

  let URL = NSURL(string: "https://****.*****.com/*****.svc/rest/GetByID")!
let mutableURLRequest = NSMutableURLRequest(URL: URL)
mutableURLRequest.HTTPMethod = "POST"

let parameters = ["ID": "23"]

do {
    mutableURLRequest.HTTPBody = try NSJSONSerialization.dataWithJSONObject(parameters, options: NSJSONWritingOptions())
} catch {
}

mutableURLRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")

Alamofire.request(mutableURLRequest)
    .responseJSON{
        response in
        if let JSON = response.result.value{

            let dataSelected = [JSON.valueForKey("Price")!]         //Quando vem apenas um objecto
            print("RESULTADO \(dataSelected)")
        }
}
