To avoid that you can call the reloadImmediately() To support the old iOS version, it is using NSDiffableDataSourceSnapshot above iOS 13, and using the data directly into a CustomUICollectionViewDataSource below iOS 13, to reduce the count of recreated NSDiffableDataSourceSnapshot instances, so the reload cells of CollectionView are async. View: )įor more on usage, check out the difference in ImplementingModernCollectionViews.

UICollectionViewDiffableDataSource : only supports one Section type and one Item typeĬonfigableCollectionView: multiple items and sections supported! Usage initialization Use for specific Item type

Multiple Item types and Sections supported! The touch to cell is based on hittest rather than cell.bounds(this is how UICollectionView work), so you can override the view’s hittest you use to make sure your tap action works properly. No distinction between NSDiffableDataSourceSectionSnapshot and NSDiffableDataSourceSnapshot UICollectionViewDiffableDataSource: once you append a repeated object, it crashes, even in release, and it doesn't someTimes in some iOS versionsĬonfigableCollectionView : only assert during debugging when you append a repetitive object Easlier UICollectionViewDiffableDataSource: iOS 13 requiredĬonfigableCollectionView: iOS 9 required, but technically supporting all iOS versions since iOS 6 Safer Advantages Over 90% of test coverage More iOS version support The demo is based on Apple's ImplementingModernCollectionViews. Create CollectionView in a similar way to new DataSource introdeced in iOS 13
