Swift: using UIModalTransitionStyle.flipHorizontal shows a black view

Question

I'm trying to implement UIModalTransitionStyle.flipHorizontal and it works but it shows just a black view. here is my code:

@IBAction func loadNextView(_ sender:UIButton){

    let nextVC = NextViewController()
    nextVC.modalTransitionStyle = UIModalTransitionStyle.flipHorizontal
    self.present(nextVC, animated: true, completion: nil)
}

Any of you knows why it shows a black view? or how can show the correct view?

I'll really appreciate your help

NextViewController is in storyboard ?? – Shehata Gamal Jun 25 '18 at 20:24 — Shehata Gamal, Jun 25 '18 at 20:24

You need to load the VC like this [ nextID is it's id in storyboard ]

let nextVC  = self.storyboard?.instantiateViewController(withIdentifier: "nextID") as! NextViewController

This works. Thank you. Quick question if I want to dismiss the NextViewController with same UIModalTransitionStyle.flipHorizontal. How can do that? – user2924482 Jun 25 '18 at 20:39
You can use **self.dismiss(animated:true,completion:nil)** – Shehata Gamal Jun 25 '18 at 20:42

Try setting the presented view controller's modalPresentationStyle to overCurrentContext:

nextVC.modalPresentationStyle = .overCurrentContext

What is the difference between `nextVC.modalPresentationStyle = .overCurrentContext` and `nextVC.modalTransitionStyle = UIModalTransitionStyle.flipHorizontal` ? – user2924482 Jun 26 '18 at 17:15
These are two different things, please check Apple documentation. – Xchord Jun 27 '18 at 06:12
