According to the Apple Documentation for WebView (https://developer.apple.com/library/mac/documentation/Cocoa/Reference/WebKit/Classes/WebView_Class/)

You can just connect the respective button outlets like this :

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

@IBAction func reload(sender: AnyObject) {
    self.webView.reload()
}

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

Do also check that canGoBack and canGoForward are set to true (read-only).

If the buttons are also created programmatically, you can add selector such as Selector("goBack") and create a func goBack() {}

For ObjectiveC you can do it like this: 

- (IBAction)browserGoBack
{
    [self.webView goBack];
}

- (IBAction)browserGoForward
{
    [self.webView goForward];
}

- (IBAction)browserRefresh
{
    [self.webView reload];
}

You can do some additional check on button action:

    @IBAction func barBackButtonAction(sender: AnyObject) {
      if webView.canGoBack {
         webView.goBack()
      }

    }


   @IBAction func barForwardButtonAction(sender: AnyObject) {
     if webView.canGoForward{
        webView.goForward()
     }
   }
