Hello. I am building an AVP app with a C++ engine in Metal. From Swift, I get a spatial event from the layerRenderer, and I want to send the event data to my engine. But I have a problem: I need the event ID value (SpatialEventCollection.Event.ID), which I can see in the debugger (it has a value of 1 or 2 depending on the hand), but I need that value as an Int to pass it to the engine. Any ideas on how to do this? Thanks.
