Converting Android post request to iOS swift using NSURLSession

I'm trying to convert my Android post request to iOS (Swift). Currently, this is the Android code:

JSONObject json = new JSONObject();
json.put("major", Major);
json.put("minor", Minor);
json.put("uuid", UUID);
json.put("userid", id);

int TIMEOUT_MILLISEC = 10000; // = 10 seconds

HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
HttpClient client = new DefaultHttpClient(httpParams);

HttpPost request = new HttpPost("http://" + ipAddress + ":8080/");
request.setHeader("Content-Type", "application/json");

request.setEntity(new ByteArrayEntity(
HttpResponse response = client.execute(request);

This works perfectly fine.
However, when I try to convert it to Swift, the server doesn't receive anything even though I know that it's executing the request.


var request = NSMutableURLRequest(URL: NSURL(string: URLString)!)
var session = NSURLSession.sharedSession()
request.HTTPMethod = "POST"

var params = ["major": "1", "minor": "2", "uuid": "00000000-1111-2222-3333-444444444444", "userid": "3"] as Dictionary<String, String>

request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(params, options: [])

request.addValue("application/json", forHTTPHeaderField: "Content-Type")
let task = session.dataTaskWithRequest(request) { data, response, error in
guard data != nil else {
print("no data found: \(error)")

do {
if let json = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? NSDictionary {
let success = json["success"] as? Int
} else {
let jsonStr = NSString(data: data!, encoding: NSUTF8StringEncoding)
} catch let parseError {
let jsonStr = NSString(data: data!, encoding: NSUTF8StringEncoding)

Any help or direction would be nice. Thanks.

task.resume() after block will do the job
