0.1.9

This release closes the 0.1.9 milestone.

• Drop support for iOS 15. Minimum iOS 16 now required.
• Fixed a (potential) bug where cells with the same name, but in different modules, would provide the same (conflicting) default reuseIdentifier. Default reuseIdentifiers now return the fully qualified type name. (@jessesquires, #150, #154)
  • Previous behavior: "MyCellClassName"
  • New behavior: "MyModuleName.MyCellClassName"
  • Note: This should be a transparent change and not impact any existing code. If you were previously working around this issue by providing a custom reuseIdentifier, you can now adopt the default implementation instead.
• Fixed possible crash in async version of CollectionViewDriver.update(viewModel: animated:) due to incorrect handling of the continuation. (@jessesquires, #152, #155)
• Improve debug descriptions (i.e., CustomDebugStringConvertible) for various types. (@nuomi1, #139)
• Implement (optional) debug logging for view model updates. You can now provide a logger for debugging purposes by setting CollectionViewDriver.logger. The library provides a default implementation via RCKLogger.shared. (@nuomi1, #141)
• Upgrade to Xcode 26. (@jessesquires, #153)

Full Changelog: 0.1.8...0.1.9

0.1.8

• Allow setting a UICollectionViewDelegateFlowLayout object to receive flow layout events from the collection view. (@jessesquires, #134)
• Swift Concurrency improvements:
  • @MainActor annotations have been removed from most top-level types and protocols, instead opting to apply @MainActor to individual members only where necessary. (@jessesquires, #135)
  • DiffableViewModel is now marked as Sendable. This means Sendable also applies to CellViewModel, SupplementaryViewModel, SectionViewModel, and CollectionViewModel. (@jessesquires, #137)
• Various performance improvements. Notably, when configuring CollectionViewDriver to perform diffing on a background queue via CollectionViewDriverOptions.diffOnBackgroundQueue, more operations are now performed in the background that were previously running on the main thread. (@jessesquires, #136, #137, @lachenmayer, #138)

Full Changelog: 0.1.7...0.1.8

0.1.7

• Upgraded to Xcode 16. (@jessesquires, #116)
• Reverted back to Swift 5 language mode because of issues in UIKit. (@jessesquires, #116)
• Applying a snapshot using reloadData now always occurs on the main thread. (@jessesquires, #116)
• Implemented additional selection APIs for CellViewModel: shouldSelect, shouldDeselect, didDeselect(). (@nuomi1, #127)
• Allow setting a UIScrollViewDelegate object to receive scroll view events from the collection view. (@ruddfawcett, #131, #133)

Full Changelog: 0.1.6...0.1.7

0.1.6

• Fixed a potential crash (in DiffableDataSource) when hiding a collection view before animations complete when diffing. This may have caused a crash with the message Fatal error: Attempted to read an unowned reference but the object was already deallocated. (@lachenmayer, #125, #126)

Full Changelog: 0.1.5...0.1.6

0.1.5

• Implemented didHighlight() and didUnhighlight() APIs for CellViewModel. (@nuomi1, #123)

Full Changelog: 0.1.4...0.1.5

0.1.4

• Implemented willDisplay() and didEndDisplaying() APIs for both CellViewModel and SupplementaryViewModel. (@nuomi1, #121)

Full Changelog: 0.1.3...0.1.4

0.1.3

• Improve debug descriptions for CollectionViewModel and SectionViewModel (@nuomi1, #119, #120)

Full Changelog: 0.1.2...0.1.3

0.1.2

• Fixed bug when chaining multiple calls to eraseToAnyViewModel() for both CellViewModel and and SupplementaryViewModel. Previously, it was possible "double erase" a view model by calling eraseToAnyViewModel() multiple times, thus actually losing type information. Now, consecutive calls to eraseToAnyViewModel() have no effect. (@nuomi1, #117)

Full Changelog: 0.1.1...0.1.2

0.1.1

Minor documentation updates.

Full Changelog: 0.1.0...0.1.1

0.1.0

Initial release. 🎉

Note: despite being a 0.1 release, this library is ready to use! I do not expect major API churn. I'm only being cautious with versioning for now while continuing to collect feedback on the API.
