Have you tried the URL in a web browser to see how long the response takes ?

0 dalay in the browser because I hit json file, but when I downlaod images by URLSession and convert it to data to show it inside UIImage, it takes a long time.

I used URLSession and Alamofire, same response time.

More explenations, I want to reuse fetched images in sub-views or anywhere else. In this point , Images take atime to be presented.
