I tried code example https://github.com/ykyouhei/KYDrawerController/tree/master/Example/Code

I can open menu only programmatically because everything is gone within my controller view and top bar:

    if let drawerController = navigationController?.parent as? KYDrawerController {
        drawerController.setDrawerState(.opened, animated: true)
    }
