刪除SceneDelegate 回復舊有AppDelegate 🤙

簡介

如何刪除SceneDelegate? Xcode新版本添加了SceneDelegate區隔了畫面與功能，如果你還不習慣想刪除SceneDelegate可以參考這篇

1. 刪除SceneDelegate.swift檔案

2.刪除AppDelegate有關UISceneSession Lifecycle的Code

AppDelegate.swift

// MARK: UISceneSession Lifecycle
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
    // Called when a new scene session is being created.
    // Use this method to select a configuration to create the new scene with.
    return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}

func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
    // Called when the user discards a scene session.
    // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
    // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}

3.在AppDelegate加入window

var window: UIWindow?

import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow? //新增
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        return true
    }
}

4.在Info.plist刪除Application Scene Manifest Key

直接按-符號
