I’m working with one challenge on Xcode with SnapKit and with out storyboard.
I did not contact AppDelegate
I’ve this code on SceneDelegate

import UIKit

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

    var window: UIWindow?


    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, choices connectionOptions: UIScene.ConnectionOptions) {
        guard let windowScene = (scene as? UIWindowScene) else { return }
        window = UIWindow(windowScene: windowScene)
        window?.makeKeyAndVisible()
        window?.rootViewController = TabBarController()
    }
}

Venture’s hierarchy like that:

1. TabBarController
2. ViewController
3. HomeCollectionViewCell

• ShopPage(Group)
  …

• MessagePage(Group)
  …

• ProfilePage(Group)

1. ProfileViewController
2. SettingsViewController

I need to open SettingsViewController when settingsButton(on ProfileViewController) tupped

That is my code within the TabBarController:

import UIKit

class TabBarController: UITabBarController {

    override func viewDidLoad() {
        tremendous.viewDidLoad()
        self.setupTabs()
        selectedIndex = 3
        tabBar.backgroundColor = .systemBackground
        tabBar.tintColor = UIColor(purple: 0, inexperienced: 155/255, blue: 247/255, alpha: 1)
    }
    
    //MARK: - Tab Setup
    non-public func setupTabs(){
        let residence = self.createNav(title: "Dwelling", picture: UIImage(systemName: "home"), vc: ViewController())
        let store = self.createNav(title: "Store", picture: UIImage(systemName: "bag"), vc: ShopViewController())
        let message = self.createNav(title: "Message", picture: UIImage(systemName: "ellipsis.message"), vc: MessageViewController())
        let profile = self.createNav(title: "Profile", picture: UIImage(systemName: "individual"), vc: ProfileViewController())
        self.setViewControllers([home, shop, message, profile], animated: true)
    }
    
    non-public func createNav(title: String, picture: UIImage?, vc: UIViewController) -> UINavigationController{
        let nav = UINavigationController(rootViewController: vc)
        nav.tabBarItem.title = title
        nav.tabBarItem.picture = picture
        return nav
    }
}

That is my code within the ProfileViewController:

class ProfileViewController: UIViewController {
    non-public lazy var settingButton: UIButton = {
        let button = UIButton()
        button.setImage(UIImage(systemName: "gearshape"), for: .regular)
        button.addTarget(self, motion: #selector(openSettings), for: .touchUpInside)
        return button
    }()

    override func viewDidLoad() {
        tremendous.viewDidLoad()
        view.backgroundColor = UIColor(purple: 250/255, inexperienced: 250/255, blue: 250/255, alpha: 1)
        setupUI()
    }
    
    @objc non-public func openSettings() {
        let settingsViewController = SettingsViewController()
        navigationController?.pushViewController(settingsViewController, animated: true)
    }
}

non-public extension ProfileViewController {
    func setupUI() {
        setupViews()
        setupConstraints()
    }
    
    func setupViews() {
        view.addSubview(settingButton)
    }
    
    func setupConstraints() {
        settingButton.snp.makeConstraints { make in
            make.heart.equalToSuperview()
        }
    }
}

However after I tupped settingButton nothing taking place

I attempted to set rootViewController like that on Scene Delegate:
window?.rootViewController = UINavigationController(rootViewController: TabBarController())

Additionally I attempted right here set ProfileViewController as a rootViewController

Additionally I attempted with current methodology:

@objc non-public func openSettings() {
    let settingsViewController = SettingsViewController()
    current(settingsViewController, animated: true)
}

did’t helped(
