Passing multiple parameters in HTTP POST request

I am a beginner at this and I am really stuck. I want to upload a product by sending a POST request to the mentioned URL with an autogenerated client ID and product JSON sent as parameters. Plus I also want cookies in this request. I am finding this incredibly difficult to achieve with Alamofire, hence an NSURLConnection solution is equally welcome. Please help. Thanks in advance!

HTTP POST Request URL: http://blahblah.com/api/v1/products/saveDraft

HTTP Request Headers:
version: 0.1.7
Cookie: client=iOS; version=0.1.7; sellerId=SEL5483318784; key=178a0506-0639-4659-9495-67e5dffa42de
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
Content-Length: 1431

HTTP URL parameters: clientId=1444657827384-344b7992-8608-49b1-976a-f405defa189&[PRODUCTJSON]

The Alamofire request I tried to execute is given below. The request fails with Bad Request Error (Status code 400)

    let cookies = "client=iOS; version=" + version + "; sellerId=" + sellerId + "; key=" + sellerKey


    let manager = Manager.sharedInstance
    manager.session.configuration.HTTPAdditionalHeaders = [
        "Content-Type": "application/x-www-form-urlencoded; charset=UTF-8",
        "Cookie": cookies
    ]

    Alamofire.request(.POST, ServerConfig.ADD_PRODUCT_URL, parameters: productJSON, encoding: .JSON, headers: nil)
        .responseJSON(completionHandler: { responseRequest, responseResponse, responseResult in
            print(responseRequest!.URL)
            print(responseResponse)
            print(responseResult)
       })

Please note that the Product Json does not include the client ID. I still have to figure out a way to include them both as parameters in the HTTP POST request.

@godlike's answer is good, however you need to separate the postString parameters with ampersands not semicolons:

postString = "client=iOS&version=" + version + "&sellerId=" + sellerId + "&key=" + sellerKey

That worked for me.

Also, depending on where your input is coming from, you may want to consider encoding your variables to escape special characters. If they are coming from a user's input you could do something like this:

let encodedUserMessage = userMessage.addingPercentEncoding(withAllowedCharacters: .alphanumerics)

I would have just commented on @godlike's answer but I don't have enough reputation. Hopefully that helps someone else out as I have just spent ages trying to figure out how to pass multiple parameters in.

This is the way I am doing my post requests: 

let request = NSMutableURLRequest(URL: NSURL(string: "http://blahblah.com/api/v1/products/saveDraft")!)
request.HTTPMethod = "POST"
var postString: String?
postString = "client=iOS; version=" + version + "; sellerId=" + sellerId + "; key=" + sellerKey
request.HTTPBody = postString!.dataUsingEncoding(NSUTF8StringEncoding)
 let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
            data, response, error in

            if error != nil {
                print("error=\(error)")
                print("ERROR")
            }

//DO something
