Conv

Enables hierarchical definition of sections, items, headers, and footers that closely mirrors UICollectionView's structure, as shown in the nested closure syntax in the usage example, improving readability.

Eliminates manual cell dequeuing and casting by providing typed cells in configuration closures, reducing runtime errors and boilerplate, demonstrated with Item<ListCollectionViewCell> in the code snippets.

Uses Paul Heckel's algorithm to calculate minimal changes for reloads, enabling smooth animations and performance, highlighted with animated gifs of insert, delete, and move operations.

Keeps data source and delegate methods together in the same code block, such as cell configuration and selection handlers defined in item closures, enhancing maintainability.
