You can create an UIViewController with a UIScrollView and a pagination (scrollView pagination enabled and a pageControl). Your different tutorial views are defined inside each page in the scrollView.

the key part here is to set modalPresentationStyle of your modal controller to .overCurrentContext when you call it :

let VC = self.storyboard!.instantiateViewController(withIdentifier: "myViewController") as! MyViewController
VC.modalPresentationStyle = .overCurrentContext
VC.view.backgroundColor = UIColor(red: 0, green: 0, blue: 0, alpha: 0.2)
self.present(VC, animated: true, completion: nil)
