Web View Not Displaying Content in Swift 2.0 - ios

Question

I was following a tutorial to display content from a web view within my application. In swift 2.0, when I run the emulator I am getting no response on the emulator screen.
My code:
import UIKit
class ViewController: UIViewController {
#IBOutlet var webView: UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let url = NSURL(string: "http://www.stackoverflow.com")
let task = NSURLSession.sharedSession().dataTaskWithURL(url!) {
(data, response, error) in
if error == nil {
var urlContent = NSString(data: data!, encoding: NSUTF8StringEncoding)
print(urlContent)
dispatch_async(dispatch_get_main_queue()) {
self.webView.loadHTMLString(urlContent! as String, baseURL: nil)
}
}
}
task.resume()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

I'm pretty sure you should try to retain your data task.
Just declare stored property:
var task: NSURLSessionDataTask?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let url = NSURL(string: "http://www.stackoverflow.com")
task = NSURLSession.sharedSession().dataTaskWithURL(url!) {
(data, response, error) in
if error == nil {
var urlContent = NSString(data: data!, encoding: NSUTF8StringEncoding)
print(urlContent)
dispatch_async(dispatch_get_main_queue()) {
self.webView.loadHTMLString(urlContent! as String, baseURL: nil)
self.task = nil
}
}
}
task.resume()
