Scrolling elements in macOS native apps from Apple are indeed built using SwiftUI. SwiftUI has been increasingly adopted by Apple for building new features and apps, as well as enhancing existing ones. For instance, improvements in scrolling performance have been highlighted in the Platforms State of the Union session, where it was mentioned that SwiftUI brings idle prefetch to the Mac for the first time, significantly boosting performance. Additionally, SwiftUI is used in various Apple apps and system experiences, indicating its role in building native app components, including scrolling elements.
