The "idle prefetch" feature is being introduced to macOS through SwiftUI, as mentioned in the Platforms State of the Union. This feature is specifically highlighted as a performance improvement for SwiftUI, bringing a significant boost in performance for scrolling, especially in lists and tables with large amounts of data. There is no mention of this feature being available for AppKit in the provided context. Therefore, it seems that "idle prefetch" is currently a SwiftUI-specific enhancement on macOS.
