At WWDC 2025, Apple introduced several sessions focused on improving SwiftUI performance. Here are some highlights:
-
Optimize SwiftUI performance with Instruments: This session provides an in-depth look at using the new SwiftUI instrument in Xcode to diagnose and fix performance issues in SwiftUI apps. It covers identifying long view body updates and understanding the causes and effects of SwiftUI updates. You can start exploring this session with the chapter Discover the SwiftUI instrument.
-
What’s new in SwiftUI: This session discusses various performance improvements in SwiftUI, including enhancements to lists, scrolling, and profiling. It highlights that lists on macOS can now load significantly faster, and scrolling has been optimized to reduce frame drops. You can learn more about these improvements in the chapter Framework foundations.
-
Platforms State of the Union: This session mentions the introduction of a powerful new performance instrument to help optimize SwiftUI code, along with other improvements like faster scrolling and better list performance.
These sessions collectively provide a comprehensive overview of the new tools and techniques available to improve SwiftUI performance in your apps.
Optimize SwiftUI performance with Instruments
Discover the new SwiftUI instrument. We’ll cover how SwiftUI updates views, how changes in your app’s data affect those updates, and how the new instrument helps you visualize those causes and effects. To get the most out of this session, we recommend being familiar with writing apps in SwiftUI.
Platforms State of the Union
Discover the newest advancements on Apple platforms.
What’s new in SwiftUI
Learn what’s new in SwiftUI to build great apps for any Apple platform. We’ll explore how to give your app a brand new look and feel with Liquid Glass. Discover how to boost performance with framework enhancements and new instruments, and integrate advanced capabilities like web content and rich text editing. We’ll also show you how SwiftUI is expanding to more places, including laying out views in three dimensions.
