Making HTTP Requests in Swift

SwiftHTTPRequest.swift

//Uncomment both lines below if testing on an Xcode playground.
//import XCPlayground
//XCPSetExecutionShouldContinueIndefinitely()

let url = NSURL(string: "http://www.stackoverflow.com")

let task = NSURLSession.sharedSession().dataTaskWithURL(url) {(data, response, error) in
    println(NSString(data: data, encoding: NSUTF8StringEncoding))
}

task.resume()

does not work ....

Works for me

does not work

You need to put it in a function to work, such as:

override func viewDidLoad() {
super.viewDidLoad()
test()
}

func test() {
    println("Start Test")
    let url = NSURL(string: "http://www.stackoverflow.com")

    let task = NSURLSession.sharedSession().dataTaskWithURL(url!) {(data, response, error) in
        println(NSString(data: data, encoding: NSUTF8StringEncoding))
    }

    task.resume()
}

This works for me but for whatever reason, it doesn't work for this site: http://old.gjk.cz/suplovani.php
Any idea why?
