How can I use NavigationController and PageTabBarController at the same time?

Question

I'm sorry to bother you and I really love Material Project, I hope I could use it skillfully and make a prettier app. I wonder if I could know how can I use NavigationController and PageTabBarController at the same time, since if I want to use one of them, I have to set it in the AppDelegate as the rootViewController, then what should I do to the other one? Thanks.

I am glad you are enjoying Material :)

Take a look at this article Application Architecture with Material.

Basically, you can set the PageTabBarController as the rootViewController of the NavigationController, like this:

import UIKit
import Material

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?

    func applicationDidFinishLaunching(_ application: UIApplication) {
        let pageTabBarController = AppPageTabBarController(viewControllers: [RedViewController(), GreenViewController(), BlueViewController()], selectedIndex: 0)

        window = UIWindow(frame: Screen.bounds)
        window!.rootViewController = AppNavigationController(rootViewController: pageTabBarController)
        window!.makeKeyAndVisible()
    }
}

That should do it. All the best.
