NSURLSession parameters not recognized - swift

Question

Im attemping to make a HTTPRequest using NSURLSession. When I set the full url the request returns the correct data but when using parameters (NSJSONSerialization.dataWithJSONObject -> HTTPBody I get this error
error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."
is there something im doing wrong here?
let json = ["api_key": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"]
do {
let jsonData = try NSJSONSerialization.dataWithJSONObject(json, options: .PrettyPrinted)
let url = NSURL(string: "https://api.themoviedb.org/3/discover/movie")!
let request = NSMutableURLRequest(URL: url)
request.HTTPBody = jsonData
request.HTTPMethod = "GET"
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ data, response, error in
if error != nil{
print("Error -> \(error)")
return
}
do {
let result = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? [String:AnyObject]
print("Result -> \(result)")
} catch {
print("Error -> \(error)")
}
}
task.resume()
} catch {
print(error)
}
}
This is not a duplicate! I looked at the suggested answer (none of them worked) before asking this question

In your case that issue can be solved by changing the request.HTTPMethod = "GET" to request.HTTPMethod = "POST"
You should not send HTTP Body in the get request, to send the data with the body you should change HTTPMethod to post
Note: Please check if this api method supports POST requests, if it don't support post you can't use it with http body/post, as per doc i only find 'get' request for the discover/movie which can be like this:
let url = NSURL(string: "http://api.themoviedb.org/3/discover/movie?api_key=YOUR_API_KEY")!
let request = NSMutableURLRequest(URL: url)
request.addValue("application/json", forHTTPHeaderField: "Accept")
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(request) { data, response, error in
if let response = response, data = data {
print(response)
print(String(data: data, encoding: NSUTF8StringEncoding))
} else {
print(error)
}
}
task.resume()
