Change the root view of UIHostingController in SwiftUI

Question

For a new SwiftUI iOS app, I do the following in the SceneDelegate

if let windowScene = scene as? UIWindowScene {
    let window =          


        

Answer 1

You can make a Router class

import Foundation
import UIKit
import SwiftUI

class Router {
    
    class var window: UIWindow? {
        if let scene = UIApplication.shared.connectedScenes.first as? UIWindowScene {
            if let sceneDelegate = scene.delegate as? SceneDelegate {
                let window = UIWindow(windowScene: scene)
                sceneDelegate.window = window
                window.makeKeyAndVisible()
                return window
            }
        }
        return nil
    }
    
    static func showMain() {
        window?.rootViewController = UIHostingController(rootView: ContentView())
    }
    
}

Usage :

Router.showMain()

And with this you can decide which window you want as your root at any given time.
