InteractiveDismiss

InteractiveDismiss is a subclass of UIPresentationController for interactive modal dismiss. It supports nested scroll views like UIScrollView, UITableView, and UICollectionView. To use InteractiveDismiss, just adopt UIViewControllerTransitioningDelegate protocol and return an instance of InteractiveDismiss in presentationController(forPresented:presenting:source:). And then set .custom to modalPresentationStyle before calling present(_:animated:completion).

extension YourModalViewController: UIViewControllerTransitioningDelegate {
    func presentationController(forPresented presented: UIViewController, presenting: UIViewController?, source: UIViewController) -> UIPresentationController? {
        InteractiveDismissPresentationController(presentedViewController: presented, presenting: presenting)
    }
}

extension YourModalViewController: InteractiveDismissPresentationDelegate {
    public var nestedScrollView: UIScrollView? { scrollView }
}

func presentModal() {
    let vc = YourModalViewController()
    
    vc.modalPresentationStyle = .custom
    vc.transitioningDelegate = vc
    
    self.present(vc, animated: true)
}
