Layout Groups Items Sections
AppStore JSON APIs
In order to create an instance of UICollectionViewCompositionalLayout, you'll need to understand some basics of sections, groups, and items. Once you get used to these three components, you're ready to build some pretty fancy layouts.

Curious if there is a way to play around with the fractional size property to create a kind of scaling effect so that each item dynamically enlarges when swiped into center view, like in a horizontal carousel?

I followed your suggestions and played around with parameters. At first I cannot understand clearly the difference between group and item. But when I used absolute dimension for widthDimention, say, 80 for item's absolute width dimension and 400 for group's absolute width dimension, group(s) of four items showed and the fog cleared away. Now I understand how group and item function and interact with each other.
