Presenting modal in iOS 13 with custom height

Question

In iOS 13 there is a new behaviour for modal view controller when being presented.And I found the build-in App Photo presents a smaller model view controller.

How can I present a viewController with a custom size like this，and can slide up to a larger height?

Picture screenshots from system photo app.

Yes it is possible Presenting modal in iOS 13 with custom height. You just need to add the below code into your Presenting modal

 override func updateViewConstraints() {
        self.view.frame.size.height = UIScreen.main.bounds.height - 150
        self.view.frame.origin.y =  150
        self.view.roundCorners(corners: [.topLeft, .topRight], radius: 10.0)
        super.updateViewConstraints()
 }

 extension UIView {
   func roundCorners(corners: UIRectCorner, radius: CGFloat) {
        let path = UIBezierPath(roundedRect: bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius))
        let mask = CAShapeLayer()
        mask.path = path.cgPath
        layer.mask = mask
    }
 }
