CGImageSourceCreateThumbnailAtIndex function isn't generating cgImage for majority of the images on iOS 17.4 OS version. It works if I pass in option kCGImageSourceThumbnailMaxPixelSize, but doesn't work if this key is missing. This function works with and without kCGImageSourceThumbnailMaxPixelSize in stable OS versions. Is this a new change in iOS 17.4 beta versions?
