cannot assign a value of type [UIImage] to value type ‘UIimage’


case let .failure(error):
print(“Error downloading image: (error)”)

I’m guessing that you might have a typo in your ImageResult enum. Make sure the the associated value for success is UIImage (and not [UIImage], which is what I guess it might be typed at the moment).

enum ImageResult {
  case success(UIImage)
  case failure(Error)
