Challenge 1:

The app loads images from the web and displays them in a UICollectionView, but the behavior of the UI is weird and it’s freezing 😵‍💫

Implement a function to download the images in a smoothly way that allows a good UX when scrolling the UICollectionView.

Challenge 2:

Could you implement a method to wait until all images are downloaded before to display all in the UICollectionView? You can complement that operation with an animation while waiting

Requirements ✅

Implement the exercise number 1 & 2 completely. Keep the use of 3rd party libraries to the minimum. Please try implementing your own method to download images instead of using a downloader framework. If you use it, justify the use of it on the code.
