Test-InApp-Screenshot

Test in App Screenshot for iOS/iPadOS

1. A UIGraphicsImageRenderer object is created with the bounds of the current view.
2. The image(actions:) method is called on the renderer object. This method takes a closure, where you call render(in:) on the view's layer, passing the cgContext of the image renderer context.
3. This will create an image of the view's layer, effectively taking a screenshot.
4. The screenshot is then saved to the photo library with UIImageWriteToSavedPhotosAlbum().
5. As before, you need to have the NSPhotoLibraryAddUsageDescription key in your Info.plist to get the user's permission to save photos to the photo library.
