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.
