Starting app with SideMenu revealed

[cmaulini]

I want to start my app with the SideMenu revealed. So I try, naively, this code in my "SideMenu.Content" UIViewController

    override func viewDidLoad() {
        super.viewDidLoad()
        sideMenuController?.revealMenu(animated: false)
    }

Seem it's work, but this message appears in the console

Unbalanced calls to begin/end appearance transitions for <UIViewController: 0x7ff293d17d90>.

Could you help me?
