On pressing the comment icon its loading and pushing CommentController to the Navigation stack.
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let controller = storyboard.instantiateViewController(withIdentifier: "CommentsVC") as! CommentsController
controller.post = post
self.navigationController?.pushViewController(controller, animated: true)
Strange thing is that NavigationBar is perfect in first screen. HomeFeed(first screen) is embedded in the navigationController using storyboard.
