sideMenu not displayed after login

I have included kukushi side menu. I have done things according to the documentation. The screen shot with the codes in app delegate are below:

    func setUpHomeVC() {
    var window: UIWindow?

    let storyBoard = UIStoryboard.init(name: "Dashboard", bundle: Bundle.main)
    let contentViewController = storyBoard.instantiateViewController(withIdentifier: "DashboardViewController") as! DashboardViewController
    let menuViewController = storyBoard.instantiateViewController(withIdentifier: "MenuViewCOntroller") as! MenuViewCOntroller
    SideMenuController.preferences.basic.menuWidth = 240
    SideMenuController.preferences.basic.statusBarBehavior = .hideOnMenu
    SideMenuController.preferences.basic.position = .sideBySide
    SideMenuController.preferences.basic.direction = .left
    SideMenuController.preferences.basic.enablePanGesture = true
    SideMenuController.preferences.basic.supportedOrientations = .portrait
    SideMenuController.preferences.basic.shouldRespectLanguageDirection = true
        window = UIWindow(frame: UIScreen.main.bounds)
        window?.rootViewController = SideMenuController(contentViewController: contentViewController,
        menuViewController: menuViewController)
        window?.makeKeyAndVisible()
}

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    setUpHomeVC()
    return true
}

The identifier, class and module has been added according to the documentation. After login there is dashboard which consist of menu button. On login the code is:

 private func goToDashboard() {
    let dashboard = UIStoryboard(name: "Dashboard", bundle: nil)
    let navView = dashboard.instantiateViewController(identifier: "DashboardViewController") as DashboardViewController
    present(navView,animated: false)

}

On dashboard there is a button which have click event:

  @IBAction func btnMenuClicked(_ sender: Any) {
    print("Menu button has been clicked")
    self.sideMenuController?.revealMenu(animated: true)
}

when I click on that button the print function is called but the menu is not revealed.

Can anyone explain it. Thanks in advance.

You can setup your appDelegate like this,

  func setUpHomeVC() {
    let storyboard = UIStoryboard(name: "Your Login Storyboard", bundle: nil)
    let initialViewController = storyboard.instantiateViewController(withIdentifier: "LoginVC")
    self.window?.rootViewController = initialViewController
}

   func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    setUpHomeVC()
    return true
}

And in your login event:

    private func goToDashboard() {
    self.pushVC()

}

private func pushVC()  {
    let storyBoard = UIStoryboard.init(name: "Dashboard", bundle: Bundle.main)
    let contentViewController = storyBoard.instantiateViewController(withIdentifier: "DashboardViewController") as! DashboardViewController
    let menuViewController = storyBoard.instantiateViewController(withIdentifier: "MenuViewCOntroller") as! MenuViewCOntroller
    SideMenuController.preferences.basic.menuWidth = 240
    SideMenuController.preferences.basic.statusBarBehavior = .hideOnMenu
    SideMenuController.preferences.basic.position = .sideBySide
    SideMenuController.preferences.basic.direction = .left
    SideMenuController.preferences.basic.enablePanGesture = true
    SideMenuController.preferences.basic.supportedOrientations = .portrait
    SideMenuController.preferences.basic.shouldRespectLanguageDirection = true
    window = UIWindow(frame: UIScreen.main.bounds)
    window?.rootViewController = SideMenuController(contentViewController: contentViewController,
                                                    menuViewController: menuViewController)
    window?.makeKeyAndVisible()

}
