What is the preferred method to interface between SwiftUI and a UICollectionView

Writing an app that uses a UICollectionView and I need to add security. Found the ShinyTV demo and it is what I want to do but I am having a hard time figuring out how do I access/call the UICollectionView code?

Any help would be greatly appreciated!
