Challenge: Optimizing the collection view
(upbeat electronic music) - [Instructor] In this challenge, we are displaying solar system images from the solar system scope website into a collection view. Run the app and you will notice it will eventually load the images, however, very slowly. The app is fast downloading all the images, then updating the UI. We need the images to download asynchronously and not block the main thread. How will you solve this issue?
