Where do you see that it does cell reuse? It does not... Their docs only talk about lazy loading, not reuse or unloading, eg: https://developer.apple.com/documentation/swiftui/creating-p...

This is also why LazyVGrid/LazyHGrid are unusable as replacements for UICollectionView

Yes you can replace SwiftUI with UIKit + AppKit - replace the navigation, the text rendering, the text editing, the collection views, etc.

edit: Your link is all about how to use List
