CollectionView is a SwiftUI wrapper of UICollectionView.
Have you ever wanted to make an app solely in SwiftUI, but the processing tradeoff of using Grid, Lazy_Stack, and Lazy_Grid are too significant? Wish you could stick with SwiftUI but still get the processing power of UICollectionView? Then try out CollectionView!
It’s a SwiftUI wrapper for UICollectionView that exposes all UICollectionViewDelegate/UICollectionViewDataSourcePrefetching delegate functions (via view modifiers). Plus, on iOS 16+, you can utilize UIHostingConfiguration to use SwiftUI views for the cells.
Plus, by passing your data source as a Binding, it updates changes to the view using UICollectionViewDiffableDataSource. This also means it doesn't fully reload the view on every change, but rather, they're reloaded internally by the UICollectionView.
It’s still a work in progress (especially with testing everything + documentation), but please give it a try and send feedback my way!
- Make sure to use
.ignoresSafeArea()if it's meant to be full-screen.
- Implement
UICellConfigurationState. - Add support for section snapshots.
- Add support for expandable sections.
- Add support for section headers/footers.
- Refactor
cellRegistrationHandlerout of primary initializers and replace with aUICollectionViewDiffableDataSource<Section, Item>.CellProviderclosure to allow for more complicated configurations. - Finish documenting view modifiers.
- Work on more concrete example for README/DocC articles.
