SwiftUI 添加 AppDelegate

1、创建一个 AppDelegate 继承自 NSObject, UIApplicationDelegate

import Foundation
import UIKit

class AppDelegate: NSObject, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        return true
    }
}

2、修改原来的 App 启动入口

将 @UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
添加到如下位置

@main
struct FFApp: App {
    @UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
    var body: some Scene {
        WindowGroup {
            AppView()
        }
    }
}
