将SwiftUI视图设置为NSMenuBarItem视图属性

我正在编写一个MacOS Menubar应用程序，我想指定一个SwiftUI视图作为NSMenuItem视图。 此处显示当前代码，但这会导致菜单项被隐藏

        @IBOutlet weak var firstMenuItem: NSMenuItem?
        if let item = firstMenuItem {
            let contentView = NSHostingController(rootView: contentView)
            item.view = contentView.view
        }

---

我通过设置视图的框架解决了这个问题

if let item = firstMenuItem {
            let contentView = NSHostingController(rootView: contentView)
            contentView.view.frame.size = CGSize(width: 100, height: 100)
            item.view = mainView.view
        }
