Answer 1

In AppDelegate.swift you can add the following code:

let sb = UIStoryboard(name: "Main", bundle: nil)
let vc = sb.instantiateViewController(withIdentifier: "YourViewController_StorboardID")
self.window?.rootViewController = vc
self.window?.makeKeyAndVisible()

Of course, you need to implement your logic, based on which criteria you'll choose an appropriate view controller.

Also, don't forget to add an identity (select storyboard -> Controller Scene -> Show the identity inspector -> assign StorboardID).
