Today we will take you through latest changes apple brought in swiftUI. Let me highlight some of the most significant practical changes that developers should focus on.
- Performance improvements in list rendering and state updates make apps more responsive.
- The new
@Observable
macro is a game-changer for state management, replacing the olderObservableObject
pattern. It’s much simpler to use and more performant. - The Grid system is now much more powerful and easier to use, making complex layouts simpler to implement.
- SwiftData integration has been enhanced significantly, making it easier to work with persistent data.
- The new
TipKit
framework makes it much easier to implement in-app tips and tutorials.
