About GestureState<ManipulationState>

The source code for visionOS's WWDC23 session, Take SwiftUI to the next dimension, suddenly makes extensive use of GestureState<ManipulationState>. However, there is no sample code that shows the full extent of GestureState<ManipulationState>, nor is there any explanation of its use in the video. I cannot proceed with understanding unless you share information about this.

The VisionOS sample code projects are not linked at the bottom of relevant WWDC videos.

I think this is the one that involves interacting with a satellite?

  • @J0hn As far as I could tell, the satellite sample did not contain this code.

This worked for me:

struct ManipulationState {
  var transform: AffineTransform3D = .identity
  var active: Bool = false
}

@GestureState var manipulationState = ManipulationState()
