由于该问题最近引起了更多关注，并且唯一的答复不能完全解决问题，因此我想重复问题的编辑部分并将其标记为解决.

Since this question got more attention lately and the only reply doesn't fully solve the issue I would like to repeat the edited part of my question and mark it as resolved.

找到了一种显示swiftui而不烦人的NSPopover的方法.如果您使用SwiftUI应用生命周期，则需要具有"AppDelegate"或"NSApplicationDelegateAdaptor".然后创建NSMenu并添加可以具有自定义视图的NSMenuItem.

Found a way to show swiftui without annoying NSPopover. You'd need to have 'AppDelegate' or 'NSApplicationDelegateAdaptor' in case you use SwiftUI App lifecycle. Then you create NSMenu and add NSMenuItem that can have a custom view.

这是代码:

    let contentView = VStack {
        Text("Test Text")
        Spacer()
        HStack {
            Text("Test Text")
            Text("Test Text")
        }
        Spacer()
        Text("Test Text")
    }
    let view = NSHostingView(rootView: contentView)
    // Don't forget to set the frame, otherwise it won't be shown.
    view.frame = NSRect(x: 0, y: 0, width: 200, height: 200)
    
    let menuItem = NSMenuItem()
    menuItem.view = view
    
    let menu = NSMenu()
    menu.addItem(menuItem)
    
    // StatusItem is stored as a class property.
    self.statusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength)
    self.statusItem?.menu = menu
    self.statusItem?.button?.title = "Test"
