How to dismiss view controller after login Swift

Question

I am trying to dismiss a view controller after the user has logged in successfully, but so far it is crashing in the Home view controller when I set tableView.delegate = self in viewDidLoad() . This is the code I use after a successful login:

self.view.window?.rootViewController = HomeVC()

This is the logic I have in SceneDelegate to present the login View Controller if the user is not signed in:

if(Auth.auth().currentUser == nil){
            window = UIWindow(frame: windowScene.coordinateSpace.bounds)
            window?.windowScene = windowScene
            window?.rootViewController = OnboardingVC()
        }

How can I dismiss the OnboardingVC after a successful login?

Here is the error log from the crash:

screen parameters are unexpected: MGScreenClass1125x2436x3x495 SCREEN_TYPE(1125,2436,3,495)

Answer 1

This code will dismiss all the presented view controllers and remain root view controller:

self.view.window!.rootViewController?.dismiss(animated: false, completion: nil)

If you present the view using modal, try this:

self.dismiss(animated: true, completion: nil)

If you present the view using "push" segue, try this:

navigationController?.popViewController(animated: true)

dismiss(animated: true, completion: nil)
