Recommended Way to Implement Digital Crown Zoom + Drag for Images on watchOS
I’m trying to implement smooth zoom and drag interactions for an image on watchOS—similar to the Photos app. DTS recommended using digitalCrownRotation + scaleEffect in SwiftUI, and ChatGPT also suggests a similar approach. However, the experience still isn’t as smooth or polished as the Photos app. Before I commit fully to this direction, I want to confirm: 1. Is SwiftUI with digitalCrownRotation, scaleEffect, and DragGesture the officially recommended approach for zoom + pan on watchOS? 2. Is there any public API that provides built-in Photos-style behavior, or is a custom SwiftUI implementation expected? 3. Are there best-practice patterns for smooth scaling, maintaining image bounds, and constrained panning? Thanks for any guidance
