wwdc2023-10113 Video's manipulationState variable

Question 1: The manipulationState variable has been used many times in the 3D gestures part of wwdc2023-10113 Video. What do I need to use Expected Type for this variable?

I tried to use the following code:

    @State private var manipulationState: GestureState

Xcode error Reference to generic type 'GestureState' requires arguments in <... > Insert '<Any>' But I don't know what parameter to refer to in <Any>

Question 2: If you have all the code snippets (or similar) of the 3D gestures part in this tutorial, please send it to me. Thank you.
