Thanks. I just discovered those today. Still the bus example would be amazing to learn from. This ties somewhat into my other question today about GPU-based data structures. I'm sure the demo does a few simple things along the lines of what I'm trying to figure out.
Just curious... Why is all of the sample code in Objective-C? It's a bit of a hinderance to all of us that Apple has been convincing to transition to Swift. None of my team knows Objective-C so it a whole extra layer of conceptual noise to get through since the guides are mostly stale and the ref docs are pretty minimal.
