如何删除 macOS SwiftUI App 中的“新窗口”选项？

Question

I need to remove this option in my app

这是我的应用委托：

import AppKit
public class AppDelegate: NSObject, NSApplicationDelegate {
    public func applicationWillTerminate(_ aNotification: Notification) {
        MainViewModel.shared.saveSettings()
    }
    public func applicationDidFinishLaunching(_ notification: Notification) {
        for window in NSApp.windows {
            var style = window.styleMask
            style.remove(.resizable)
            window.styleMask = style
            window.standardWindowButton(.zoomButton)?.isHidden = true
        }
    }
    public func applicationWillFinishLaunching(_ notification: Notification) {
        NSWindow.allowsAutomaticWindowTabbing = false
    }
}

我该怎么做？

只需将 commands 修饰符添加到 WindowGroup，如下所示：

WindowGroup {
            MainView().frame(width: 300, height: 95)
        }.commands {
            CommandGroup(replacing: CommandGroupPlacement.newItem) {
            }
        }
