I found this good answer about how to make a HTTP request, I am using the next code
let url = NSURL(string: "http://www.myserver.com")
let task = NSURLSession.sharedSession().dataTaskWithURL(url) {(data, response, error) in
println(NSString(data: data, encoding: NSUTF8StringEncoding))
}
task.resume()
but I can't get any information about how to send a value using POST by this way, any idea?
