Explore multiple *divergent* UI directions for a screen as named Swift #Previews, remix the strongest elements into hybrids, fill them with lived-in sample content and edge-case states, then tune signature animations with a generated tuning panel. Produces real native SwiftUI you carry forward, not throwaway mockups. Use early — after new-app or at the start of any UI-heavy phase, before /apple:plan commits to a single layout. Based on Apple's WWDC method for prototyping with coding agents in Xcode: go wide → remix → make lived-in → tune.

Integrate your app with iOS Visual Intelligence for camera-based search and object recognition. Use when adding visual search capabilities.
