Open WebView URL in Browser

I made a very simple Swift application that loads a webpage with links on it. Whenever I click the links, they do not open. How would I got about having the links on the loaded .html webpage open in a browser window for OS X?

Here is my implementation:

import Cocoa
import WebKit

class ViewController: NSViewController {

    @IBOutlet weak var webView: WebView!

    override func viewDidLoad() {
        super.viewDidLoad()
        let urlString = "URL"
        self.webView.mainFrame.loadRequest(NSURLRequest(URL: NSURL(string: urlString)!))
    }

    override var representedObject: AnyObject? {
        didSet {
            // Update the view, if already loaded.
        }
    }
}

Also you can decide what links to open in WebView and what - in browser as easy as to write target attribute in your html page like

<a href="http://www.google.com/" target="_blank">external page</a>

And use target check in the decidePolicyForNewWindowAction, menthioned above. I've placed the full answer in this question thread. Hope you can translate it to swift yourself.

First, set your WebView's policy delegate and your initial URL as a class variable:

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

// ...

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.

    self.webView.policyDelegate = self

    self.webView.mainFrame.loadRequest(NSURLRequest(URL: self.url))
}

Then, override the delegate methods to intercept navigation.

override func webView(webView: WebView!, decidePolicyForNewWindowAction actionInformation: [NSObject : AnyObject]!, request: NSURLRequest!, newFrameName frameName: String!, decisionListener listener: WebPolicyDecisionListener!) {
    println(__LINE__) // the method is needed, the println is for debugging
}


override func webView(webView: WebView!, decidePolicyForNavigationAction actionInformation: [NSObject : AnyObject]!, request: NSURLRequest!, frame: WebFrame!, decisionListener listener: WebPolicyDecisionListener!) {
    if request.URL!.absoluteString == self.url.absoluteString { // load the initial page
        listener.use() // load the page in the app
    } else { // all other links
        NSWorkspace.sharedWorkspace().openURL(request.URL!) // take the user out of the app and into their default browser
    }
}
