[iOS] 스토리보드 없이 뷰 구성하기

1. 스토리 보드 삭제

폴더에 있는 Main.stroyboard를 삭제합니다.

2. info.plist 변경

info.plist로 이동하여 'Storyboard Name'을 삭제해줍니다.

빌드 시 에러가 발생한다면 여기를 확인해보세용!

3. Scene Delegate 설정

기본 Window의 경우

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

TabBarController인 경우

 func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        guard let windowScene = (scene as? UIWindowScene) else { return }
        window = UIWindow(windowScene: windowScene) // SceneDelegate의 프로퍼티에 설정해줌
        
        let mainTabBarController = MainTabBarController()
        // 맨 처음 보여줄 ViewController

        window?.rootViewController = mainTabBarController
        window?.makeKeyAndVisible()
        window?.windowScene = windowScene
    }

NavigationController인 경우

​func application(_ application:UIApplication, didFinishLaunchingWithOptionslaunchOptions:[UIApplication.LaunchOptionsKey: Any]?) -> Bool {
   // Override point for customization after application launch.
   
   window = UIWindow(frame:UIScreen.main.bounds)
   window?.makeKeyAndVisible()
   
   let rootViewcontroller = UINavigationController(rootViewController: NavigationViewController())
   
   window?.rootViewController = rootViewcontroller
   return true
 }

var window: UIWindow?
    
    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        
		// 1.
        guard let windowScene = (scene as? UIWindowScene) else { return }
    // 2. 
        self.window = UIWindow(windowScene: windowScene)
    // 3.
        let navigationController = UINavigationController(rootViewController: ViewController())
        self.window?.rootViewController = navigationController
    // 4.
        self.window?.makeKeyAndVisible()
	}
    ```
