Explore the latest additions to SwiftUI and discover how they can improve your apps. We’ll introduce a new Document protocol with direct disk access and snapshot-based diffing for building high-performance apps; new APIs for reordering content in lists, grids, and sections; and toolbar enhancements including visibility priority and auto-minimizing behavior. We’ll also cover expanded presentation APIs — including swipe actions on any view — plus AsyncImage caching improvements and lazy state initialization for Observable types.

Discover the latest enhancements to SwiftData. We’ll show you how to persist custom and third-party types using Codable, and group fetched data into sections in your SwiftUI app. We’ll also explore how to observe data store changes anywhere else using ModelResultsObserver and HistoryObserver, giving you the flexibility to drive powerful state objects, integrate with delegate-based architectures, and react precisely to model updates.
