Why you use switchToAuthorizedSessionViewController() in your switchToViewController() method:
func switchToViewController(identifier: String) { let viewController = self.storyboard?.instantiateViewControllerWithIdentifier(identifier) as UIViewController self.navigationController?.setViewControllers([viewController], animated: false) **switchToAuthorizedSessionViewController()** }
You will create an infinite loop with that, try this:
class AppStateViewController: UIViewController { var authorized: Bool = false { didSet { if authorized { switchToAuthorizedSessionViewController() } else { switchToUnauthorizedSessionViewController() } } } override func viewDidLoad() { super.viewDidLoad() self.authorized = false } func switchToAuthorizedSessionViewController() { let sessionViewControllerID = "AuthorizedSessionViewController" switchToViewController(sessionViewControllerID) } func switchToUnauthorizedSessionViewController() { let sessionViewControllerID = "UnauthorizedSessionViewController" switchToViewController(sessionViewControllerID) } func switchToViewController(identifier: String) { let viewController =self.storyboard?.instantiateViewControllerWithIdentifier(identifier) as UIViewController self.navigationController?.setViewControllers([viewController], animated: false) } }
with this you will be observing the property authorized and each time you change it, it will call the correct method.
