Yes, SwiftUI List performance improvements were mentioned in several sessions at WWDC 2025. In the Platforms State of the Union, it was highlighted that incremental changes like inserting new items are up to 16 times faster, and larger lists will see even bigger gains. These improvements represent a significant step forward in SwiftUI scrolling performance.
Additionally, in the What’s new in SwiftUI session, it was noted that on macOS, lists of over 100,000 items now load 6 times faster, and these lists update up to 16 times faster. Larger lists have even bigger performance gains, and there are improvements across all platforms.
These enhancements are part of a broader set of performance improvements in SwiftUI, including better scrolling and profiling capabilities.
