Get UIImage only with Kingfisher library

You could use the retrieveImage(with:options:progressBlock: completionHandler:) method of KingfisherManager for this.

Maybe something like this:

KingfisherManager.shared.retrieveImage(with: url, options: nil, progressBlock: nil, completionHandler: { image, error, cacheType, imageURL in
    print(image)
})
