Change initial view before viewDidLoad Swift

I work with Xcode Swift 7 and 2. I want to know how to execute an action before viewDidLoad my initial view. In fact I would like to change the initial view based on a parameter (if I am logged in or not) ... Should we do it in the AppDelegate? Thank you

let mainStorybord : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        
    Bool isAlreadyLogin =  <...code for to check for already logged in or not...>
        if  isAlreadyLogin
        {
    var homeVC = storyboard.instantiateViewControllerWithIdentifier("<homeVC>") as! UIViewController
    // HERE <homeVC> will be your identifier  for your sugue in storyboard for initial view after login.
            let nav : UINavigationController =  UINavigationController(rootViewController: homeVc)
            self.window?.rootViewController = nav
        }
        else
        {
    var loginVC = storyboard.instantiateViewControllerWithIdentifier("<loginVC>") as! UIViewController
    // HERE <loginVC> will be your identifier  for your sugue in storyboard for login view

            let nav : NavigationViewController = UINavigationController(rootViewController: loginVC)
            self.window?.rootViewController = nav
        }
    self.window?.makeKeyAndVisible()

This way you can initiate specific viewController from appdelegate:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)

    let storyboard = UIStoryboard(name: "Main", bundle: nil)

    let initialViewController = storyboard.instantiateViewControllerWithIdentifier("yourID")

    self.window?.rootViewController = initialViewController
    self.window?.makeKeyAndVisible()

    return true
}

Assign your storyboard ID this way:

Click on your storyboard then go to Identity Inspector at right side and give a storyboard id as shown in below image:
