SwiftUI has seen significant performance improvements, particularly in areas like lists and scrolling. For instance, lists on macOS with over 100,000 items now load six times faster and update up to 16 times faster. These enhancements are part of a broader effort to improve SwiftUI's performance across all Apple platforms, making it a great year to build apps with SwiftUI.
Additionally, SwiftUI now includes a new performance instrument in Xcode, which helps developers optimize their apps by identifying performance bottlenecks. This tool provides detailed insights into when and why views update, allowing developers to ensure their view bodies update quickly and only when necessary.
For more detailed information on these improvements, you can refer to the session What’s new in SwiftUI (07:00) and Optimize SwiftUI performance with Instruments (02:19).
