Unable to set submenu for NSMenuItem (FinderSync extension)

I'm trying to create a cascade submenu for a Finder Sync extension in Swift/Cocoa. I have the following code:

override func menuForMenuKind(menuKind: FIMenuKind) -> NSMenu! {
    let m = NSMenu(title: "")
    let mi1 = NSMenuItem(title: "item1", action: nil, keyEquivalent: "")
    let mi11 = NSMenuItem(title: "item11", action: nil, keyEquivalent: "")

    let m2 = NSMenu(title: "")
    let mi2 = NSMenuItem(title: "item2", action: nil, keyEquivalent: "")
    m2.addItem(mi2)

    m.addItem(mi1)
    m.addItem(mi11)
    m.setSubmenu(m2, forItem: mi1)
    return m
}

So what I'm trying to achieve is:

item1->
       item2 
item11

So what I actually get is a flat item1 and item11 menu list.

Any hints?

I filed a bug with Apple (#18810635), got a response that it's a duplicate of (#18531883) which is still open.

Posted the copy of the filing at OpenRadar http://openradar.appspot.com/radar?id=5772557445758976 , tweeted to a developer advocate.

If anyone knows the fate of #18531883 - this is core raison d'être for Finder Sync Extensions?

Finder Sync Extensions do not support submenus in versions before macOS 10.11.

This is stated in the code docs when you examine the FIFinderSyncProtocol header:

Specific menu item properties are used: title, action, image, and enabled. Starting in 10.11: tag, state, and indentationLevel also work, and submenus are allowed.

optional func menu(for menu: FIMenuKind) -> NSMenu?

func constructMenu() {
        let main = NSMenu()
        let submenu = NSMenu()
        let mainDropdown = NSMenuItem(title: "Some option group", action: nil, keyEquivalent: "")
        main.addItem(mainDropdown)
        main.setSubmenu(submenu, for: mainDropdown)


        submenu.addItem(NSMenuItem(title: "Option 1", action: nil, keyEquivalent: ""))
        submenu.addItem(NSMenuItem(title: "Option 2", action: nil, keyEquivalent: ""))




       // myList.setSubmenu(mylist2, for: myList)


        statusItem.menu = main
    }

I've upgraded the project to Swift 2.0, and finally made a working submenu. Posting the solution:

override func menuForMenuKind(menuKind: FIMenuKind) -> NSMenu! {
    let main = NSMenu()
    let submenu = NSMenu()
    let mainDropdown = NSMenuItem(title: "Some option group", action: nil, keyEquivalent: "")
    main.addItem(mainDropdown)
    m.setSubmenu(submenu, forItem: mainDropdown)


    submenu.addItem(NSMenuItem(title: "Option 1", action: nil, keyEquivalent: ""))
    submenu.addItem(NSMenuItem(title: "Option 2", action: nil, keyEquivalent: ""))
    return main
}

This will only work on Mac OS 10.11+, 10.10.5 still has the bug being unable to generate a submenu. So a good appraoch is generating a flat menu for < 10.11, and a cascade starting from el capitan.
