Well, you shouldn't use delegate for this. Delegates are used like some sort of a callback. For instance imagine you have a controller that will show another one:

FirstViewController -> SecondViewController

Delegates, are used in this case when your SecondViewController wants to call the FirstViewController.

In your case you just want to display SecondViewController, for this you have a few options.

The simplest if you have a navigation view controller is to push the new BrowserViewController in your didSelectCell method:

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    self.navigationController?.pushViewController(BrowserViewController(), animated: true)
}
