如何使用导航栏转换到视图控制器？

Question

I have two modules that I need to connect.

1. The authorization module, which consists of 1 screen. There is no controller Navigation on it and it is not in its stack.
2. Main application. The first screen is the root for the controller navigation.

How can I implement the transition in case of successful authorization from the authorization screen to the main application in Swift code?

My screen scheme

SOLUTION:

I use this solution for my case:

let vc = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "rootVC")
        UIApplication.shared.delegate?.window??.rootViewController = vc
        view.present(vc, animated: true) {
            self.view.dismiss(animated: false, completion: nil)
        }

Answer 1

Give storyboardId "nav" to the Navigation Controller and then present it on your login view controller.

if let nav = self.storyboard?.instantiateViewController(withIdentifier: "nav") {
    self.present(nav, animated: true, completion: nil)
}

Answer 2

on your navigation Controller on storyboard add your storyboard Id, for example I have named it as navController

In your code, from you want to show as the navigation controller as present, add this line

case if presented view Controller on same storyboard

if let navController = self.storyboard?.instantiateViewController(withIdentifier: "navController") {
    self.present(navController, animated : true, completion : nil)
}

case if presented view controller on different storyboard

let storyboard = UIStoryboard(name : STORYBOARD_NAME, bundle : nil)
let nav = storyboard.instantiateViewController(withIdentifier: "navController")
self.present(navController, animated : true, completion : nil)
