在SwiftUI中删除/替换/添加菜单

Question

我有一个简单的SwfitUI（XCode 12.4，MacOS 11.1）Mac应用程序，并且有一个AppDelegate。

如何删除默认的文件/编辑/视图/窗口/帮助菜单并替换为自定义菜单？

class AppDelegate: NSObject, NSApplicationDelegate {
    func applicationDidFinishLaunching(_ notification: Notification) {
        let _ = NSApplication.shared.windows.map { $0.tabbingMode = .disallowed }
        let mainWindow = NSApplication.shared.windows.first!
        
        mainWindow.backgroundColor = NSColor(red: 1, green: 1, blue: 1, alpha: 0.3)
        mainWindow.titlebarAppearsTransparent = true
        mainWindow.titleVisibility = .hidden        
        mainWindow.backgroundColor = NSColor(red: 1, green: 1, blue: 1, alpha: 1)
    }
    
    func applicationWillFinishLaunching(_ notification: Notification) {
        NSWindow.allowsAutomaticWindowTabbing = false
    }
}

@main
struct VeyBoardApp: App {
    @NSApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
    
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

在我看来，你不应该这样做，我们Mac用户期望每个程序都有这些菜单。 - Joakim Danielson

可以像这样完成：

@main
struct VeyBoardApp: App {
    @NSApplicationDelegateAdaptor(AppDelegate.self) var appDelegate

    var body: some Scene {
        WindowGroup {
            ContentView()
        }
        .commands {
            CommandGroup(replacing: CommandGroupPlacement.newItem) {}
            CommandGroup(replacing: CommandGroupPlacement.sidebar) {
                Button("New menu item in View") {
                    print("clicked")
                }
            }
        }
    }
}

这个答案确实有点帮助，因为它展示了如何移除/禁用菜单项。但是它并没有展示如何完全移除一个菜单。例如，我可以移除默认的“帮助”菜单项，但是菜单“帮助”仍然存在一个搜索框。你怎么才能完全移除“帮助”菜单呢？ - G. Marc
