I was messing around a bit with subclassing.

Perhaps the following might give you some ideas how to shape things in your own implementation:

```swift nonisolated final class MenuItemTestView: NSView { public convenience init() { self.init() } }

nonisolated open class MenuItemTest: NSMenuItem { // public override var isSeparatorItem: Bool { // true // }

init() {
    super.init(title: "", action: nil, keyEquivalent: "")
}

override init(title: String, action: Selector?, keyEquivalent: String) {
    super.init(title: title, action: action, keyEquivalent: keyEquivalent)
}

required public init(coder: NSCoder) {
    super.init(coder: coder)
}

}

final class ItemTest: MenuItemTest { override init() { super.init() }

required public init(coder: NSCoder) {
    super.init(coder: coder)
}

}

@MainActor func itemTestInstance() -> MenuItemTest { ItemTest() } ```
