Prevent fullscreen

[UtkuDalmaz]

Hi there

How can I prevent modal viewcontroller to be fullscreen?

You can achieve this by cancelling the pan when the drag offset becomes negative.

class HalfModalPresentationController: UIPresentationController {

    // ...

    func onPan(pan: UIPanGestureRecognizer) -> Void {
        let endPoint = pan.translation(in: pan.view?.superview)

        guard endPoint.y > 0 else {
            return pan.state = .cancelled
        }

        // ...

    }

    // ...

}
