What statements have been added to SwiftUI in visionOS development compared with the original SwiftUI?
SwiftUI in visionOS
What's specific to visionOS that is new is "only" Model3D and RealityView I think in terms of views and modifiers we have .glassBackgroundEffect(). There might be more but I don't think there's a list.
