SwiftUI Image Saving Fails During .WEBP Image Conversion - swift

Question

My code converts the output .WEBP image from an URL on user's screen, and saves it to iOS photo library when the user clicks the download button.
The download button opens up the share sheet, and user clicks "save image" and it fails while saving after user gives its consent to access the photo library.
It does not fail on the simulator, but when I click the save image, it does not show any image in the photo library, because the image after .Webp conversion returns an empty file.

func imageFrom(url:URL) -> UIImage {
DispatchQueue.global().async { [weak self] in
if let data = try? Data(contentsOf: url){
if let image = UIImage(data:data){
DispatchQueue.main.async{
self?.image = image
}
}
}
}
return image!
}
}
extension String {
func load() -> UIImage {
do {
guard let url = URL(string: self)
else {
return UIImage()
}
let data: Data = try Data(contentsOf:

return UIImage(data:

return UIImage()
