swiftui - macOS 14 SwiftUI App启动时打开设置窗口的替代方法？

Question

swiftUI macos App, 目前只有 设置和 menubar 两个视图，没有主窗体，怎么实现在App启动的时候，打开设置窗口，

在macos 13 的时候可以使用

NSApp.sendAction (Selector(("showSettingsWindow:")),to:nil, from:nil)

但是macos 14 的时候，showSettingsWindow 会提示使用，SettingsLink，SettingsLink是视图，又不能在生命周期中使用。

stackoverflow 上找到了答案
扩展 NSApplication 一个 openSettings 方法 ，然后在 appDelegate 的applicationDidFinishLaunching 中调用

代码调用

func applicationDidFinishLaunching(_ aNotification: Notification) {        NSApplication.shared.openSettings()           }

拓展 NSApplication
