How to send a POST request with BODY in swift

Question

I'm trying to make a post request with a body in swift using Alamofire.

my json body looks like :

{
    "IdQuiz" : 102,
    "IdUser" : "iosclient",
    "User" : "iosclient",
    "List":[
        {
        "IdQuestion" : 5,
        "IdProposition": 2,
        "Time" : 32
        },
        {
        "IdQuestion" : 4,
        "IdProposition": 3,
        "Time" : 9
        }
    ]
}

I'm trying to make let list with NSDictionnary which look like :

[[Time: 30, IdQuestion: 6510, idProposition: 10], [Time: 30, IdQuestion: 8284, idProposition: 10]]

and my request using Alamofire looks like :

Alamofire.request(.POST, "http://myserver.com", parameters: ["IdQuiz":"102","IdUser":"iOSclient","User":"iOSClient","List":list ], encoding: .JSON)
            .response { request, response, data, error in
            let dataString = NSString(data: data!, encoding:NSUTF8StringEncoding)
                println(dataString)
        }

The request has an error and I believe the problem is with Dictionary list, cause if I make a request without the list it works fine, so any idea ?

I have tried the solution suggested but I'm facing the same problem :

 let json = ["List":list,"IdQuiz":"102","IdUser":"iOSclient","UserInformation":"iOSClient"]
        let data = NSJSONSerialization.dataWithJSONObject(json, options: NSJSONWritingOptions.PrettyPrinted,error:nil)
        let jsons = NSString(data: data!, encoding: NSUTF8StringEncoding)



    Alamofire.request(.POST, "http://myserver.com", parameters: [:], encoding: .Custom({
        (convertible, params) in
        var mutableRequest = convertible.URLRequest.copy() as! NSMutableURLRequest
        mutableRequest.HTTPBody = jsons!.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
        return (mutableRequest, nil)
    }))
        .response { request, response, data, error in
        let dataString = NSString(data: data!, encoding:NSUTF8StringEncoding)
           println(dataString)
    }

If you are using Alamofire v4.0+ then the accepted answer would look like this:

let parameters: [String: Any] = [
    "IdQuiz" : 102,
    "IdUser" : "iosclient",
    "User" : "iosclient",
    "List": [
        [
            "IdQuestion" : 5,
            "IdProposition": 2,
            "Time" : 32
        ],
        [
            "IdQuestion" : 4,
            "IdProposition": 3,
            "Time" : 9
        ]
    ]
]

Alamofire.request("http://myserver.com", method: .post, parameters: parameters, encoding: JSONEncoding.default)
    .responseJSON { response in
        print(response)
    }
