Here's what you'd do if your rootViewController did NOT inherit from UINavigationViewController:

Basically you check what the currently presented tab is and then push from THAT view controller, rather than the rootViewController that inherits from UITabBarController.

        let root = self.window?.rootViewController as UITabBarController

        switch(root.selectedIndex){
        case 0:
            root.viewControllers?[0].pushViewController(viewController, animated: true)
            break;
        case 1:
            root.viewControllers?[1].pushViewController(viewController, animated: true)
            break
        default:
            println("Error presenting ViewController")
            break;
        }

My application has an initial/rootViewController that inherits from UITabBarController, each of it's UITabBar Relationship Controllers inherit from UINavigationController, allowing me to pushViewController from them.
