Is there any possible way to snapshot a screen with modal sheet on the screen

[looneytsci]

I'm trying to make a snapshot for a view, which can open bottomSheet via .fullScreenCover and transparent background. Looks like It captures only the view layer without bottomSheet layer. Can I make the snapshot of the full view hierarchy? Or can I implement some custom snapshotting strategy with modal screen capturing?

PS this is for SwiftUI project

I can make a snapshot of a Alert using this code below, propably it'll work to sheets @looneytsci

extension Snapshotting where Value: UIViewController, Format == UIImage {    
    public static func windowedImage(interfaceStyle: UIUserInterfaceStyle = .unspecified,
                                     precision: Float = 0.98,
                                     perceptualPrecision: Float = 1) -> Snapshotting {
        return Snapshotting<UIImage, UIImage>.image(
            precision: precision,
            perceptualPrecision: perceptualPrecision,
            scale: nil
        ).asyncPullback { viewController in
            Async<UIImage> { callback in
                UIView.setAnimationsEnabled(false)
                let window = UIApplication.shared.windows.first!
                window.rootViewController = viewController
                window.windowScene?.traitOverrides.userInterfaceStyle = interfaceStyle
                DispatchQueue.main.async {
                    let image = UIGraphicsImageRenderer(bounds: window.bounds).image { _ in
                        window.drawHierarchy(in: window.bounds, afterScreenUpdates: true)
                    }
                    callback(image)
                    UIView.setAnimationsEnabled(true)
                }
            }
        }
    }
}

Im facing the same issue. The code above doesn't snapshot a sheet.

So far, this isn't working for me. I was trying to test this alert:

struct TestAlert: View {
    @State var showAlert = true

    var body: some View {
        Text("Hello, World")
            .alert(isPresented: $showAlert) {
                Alert(title: Text("Alert Message"))
            }
    }
}

The test I have is:

    func testAlert() throws {
        assertSnapshot(of: TestAlert(), as: .image(drawHierarchyInKeyWindow: true, layout: .device(config: .iPhone8)))
    }

Cat you try

 let vc = UIHostingController(rootView: TestAlert())
 let window = UIApplication.shared.windows.first!

let navigation =  UINavigationController(rootViewController: vc)
navigation.modalPresentationStyle = .overFullScreen
window.rootViewController?.present(navigation, animated: false)
assertSnapshots(of: UIViewController(), as: [.windowedImage()])

Is that last line supposed to be:

assertSnapshots(of: navigation, as: [.windowedImage()])

?
