Question

I want to logout from application using settings bundle.

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

//enable_logout key for logout switch identifire in setting budle plist.
        let userLogout =  UserDefaults.standard.bool(forKey: "enabled_logout")
        print(userLogout)

            let userLogin =  UserDefaults.standard.bool(forKey: "isUserLogin")
            if userLogin {

                let homeController = HomeController()
                let homeNav = UINavigationController.init(rootViewController: homeController)


                let aboutController = AboutController()
                let aboutNav = UINavigationController.init(rootViewController: aboutController)

                let userBaseController = UserBaseInfoController()
                let userBaseNav = UINavigationController.init(rootViewController: userBaseController)

                tabbarController.viewControllers =[homeNav,userBaseNav,aboutNav]

                self.window?.rootViewController = tabbarController

            }
            else {

                let login = LoginController()
                self.window?.rootViewController = login


            }

I am solve this problem, instead check enable_logout key in didFinishLaunchingWithOptions method, I checked in applicationWillEnterForeground methods.

Here is my code:

func applicationWillEnterForeground(_ application: UIApplication) {

        let userLogout =  UserDefaults.standard.bool(forKey: "enable_logout")
        print(userLogout)


        if !userLogout {

            let homeController = HomeController()
            let homeNav = UINavigationController.init(rootViewController: homeController)


            let aboutController = AboutController()
            let aboutNav = UINavigationController.init(rootViewController: aboutController)

            let userBaseController = UserBaseInfoController()
            let userBaseNav = UINavigationController.init(rootViewController: userBaseController)

            tabbarController.viewControllers = [homeNav,userBaseNav,aboutNav]

            self.window?.rootViewController = tabbarController

        }
        else {

            let login = LoginController()
            self.window?.rootViewController = login

        }

    }
