最后一个窗口关闭时关闭 SwiftUI 应用程序[重复]

当用户关闭最后一个窗口时，是否可以关闭 macOS SwiftUI 应用程序，类似于applicationShouldTerminateAfterLastWindowClosed应用程序委托函数。

func applicationShouldTerminateAfterLastWindowClosed(NSApplication) -> Bool

我在这里找到了答案https://www.hackingwithswift.com/quick-start/swiftui/how-to-add-an-appdelegate-to-a-swiftui-app https://www.hackingwithswift.com/quick-start/swiftui/how-to-add-an-appdelegate-to-a-swiftui-app

为 AppDelegate 创建一个类

import Foundation
import AppKit

class AppDelegate: NSObject, NSApplicationDelegate {
    func applicationShouldTerminateAfterLastWindowClosed(_ sender: NSApplication) -> Bool {
        return true
    }
}

将属性包装器添加到您的 SwiftUI App 类

import SwiftUI

@main
struct SwiftUIApp: App {
    @NSApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
    
    var body: some Scene {
        WindowGroup {
            ContentView()
                .frame(minWidth: 300, idealWidth: 300, maxWidth: .infinity, minHeight: 300, idealHeight: 300, maxHeight: .infinity)
    
        }
    }
}
