I think this is what you are looking for:

let nav1 = UINavigationController(rootViewController: UIViewController())
let nav2 = UINavigationController(rootViewController: UIViewController())

let tab = UITabBarController()
tab.viewControllers = [nav1, nav2]

appdelegate.window!.rootViewController = tab
