BUG?

Hello sir, thanks for your library.
i'm trying to implement it when user logged in to expand the animation then move to the second view controller ( it is like this FirstViewController -> navigationController -> SecondViewcontroller )

but when the animation expend it looks like i see the first viewcontroller pushed then i see it moving to the second... why ? ( btw i'm using performSegue, present not working i don't know why...)

thanks you for your help :)

let storyboard = UIStoryboard(name: "Main", bundle: nil) let navController = storyboard.instantiateViewController(withIdentifier: "FinalBuy") as! FinalBuyViewController self.present(navController, animated: true, completion: nil)

trying now like this the transition is working.. but the navbar dont show..
