You can set your storyboard programmatically like this in the app delegate:

window = UIWindow(frame: UIScreen.main.bounds)
// Or "Admin"
window!.rootViewController = UIStoryboard(name: "Main", bundle: nil).instantiateInitialViewController()! 
window!.makeKeyAndVisible()

You could actually set any view controller. That's how no-storyboard approach is wired up.

Oh, another advantage of doing it in code is it delays the storyboard initialization. If you use the "Main Interface" settings in Xcode, the storyboard is actually initialized BEFORE the application:didFinishLaunchingWithOptions method.
