Presenting LightBoxController doesn't work.

I've updated to the latest version, I saw in previous version that this issue was resolved. However, it isn't solved yet. App freezes when presenting LightBoxController.

Don't know if we have the same problem, but when trying to present Lightbox from a .pageSheet modalPresentationStyle (the default style now in iOS 13) I get a transparent screen that blocks anything from happening.

My solution (workaround) was to just start an empty view controller on .fullScreen and then present lightbox from there

Here's a helper class, maybe it helps:

class FullScreenImageViewController: UIViewController {

    private var controller: LightboxController?
    private var hasDisplayed = false

    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = .black
    }

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        guard let controller = controller else {
            return
        }
        if hasDisplayed {
            dismiss(animated: false, completion: nil)
        } else {
            hasDisplayed = true
            controller.modalPresentationStyle = .fullScreen
            controller.dynamicBackground = true
            present(controller, animated: true)
        }
    }

    func configure(image: UIImage) {
        controller = LightboxController(images: [.init(image: image)])
    }

    func configure(imageURL: URL) {
        controller = LightboxController(images: [.init(imageURL: imageURL)])
    }
}

Usage

let fullScreenImageScene = FullScreenImageViewController()
fullScreenImageScene.modalPresentationStyle = .fullScreen
fullScreenImageScene.configure(image: myImage)
present(fullScreenImageScene, animated: false)
