Web Browser Application Doesn't Work

I've been playing around with Xcode and made a Web Browser Application but when i type a valid URL nothing comes up. is something wrong with the syntax?

code:

import UIKit

class ViewController: UIViewController, UITextFieldDelegate {

    var address: String = String()



    @IBOutlet weak var webAddress: UITextField!
    @IBOutlet weak var webView: UIWebView!


    @IBAction func goPressed(sender: AnyObject) {
        webAddress.resignFirstResponder()
        loadWebPage()
    }

    @IBAction func leftPressed(sender: AnyObject) {
        webView.goBack()
    }

    @IBAction func rightPressed(sender: AnyObject) {
        webView.goForward()
    }

    @IBAction func zoomInPressed(sender: AnyObject) {
        webView.scrollView.zoomScale += 0.1
    }

    @IBAction func zoomOutPressed(sender: AnyObject) {
        webView.scrollView.zoomScale -= 0.1
    }

    func loadWebPage() {

        if webAddress.text != "" {

            address = address.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())
            address = self.webAddress.text!

            if address.hasPrefix("www. ") {
                address = "http://" + address
            }else if !address.hasPrefix("http://") {

            }

            }
        let url = NSURL(string: address)
        let request = NSURLRequest(URL: url!)
        webView.loadRequest(request)

        }



    func textFieldShouldReturn(textField: UITextField) -> Bool {
         webAddress.resignFirstResponder()
        loadWebPage()
        return true

    }

    override func viewDidLoad() {
        super.viewDidLoad()

        webAddress.delegate = self
        webView.scalesPageToFit = true
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}
