I have a relatively simple SceneKit program that moves 2 cubes (i.e. 2 SCNNode box objects) in space and reports if there is a collision in the console.
The program works fine on Yosemite with Xcode 6.4 so I know the physics world, its delegate and its collision handler methods are being set up and called correctly. If I take the same program and recompile it on El Capitan using Xcode 7 beta, the collision handler methods never get called; breakpoints don't trigger, NSLog messages don't appear, etc.
Anyone else run into this? Do I need to do some other setup to get collision detection working in the beta and I've missed it in the documentation.
Search doesn't yield any results for this, but I find it hard to believe I'm the only one seeing this at such a late stage in the beta so I assume I'm doing something wrong.
Any pointers appreciated.
