Scene Kit Tutorial with Swift Part 3: Physics

In this 5-part Scene Kit tutorial series, you'll learn how to make your first 3D iOS game: a game like Fruit Ninja called Geometry Fighter!

This is a companion discussion topic for the original entry at https://www.raywenderlich.com/1258-scene-kit-tutorial-with-swift-part-3-physics

Everything was going very smoothly, but I’ve hit a brick wall with the Float extension. It’s correctly copied and added to the project and the Project Explorer folder it’s in has Target Membership checked for GeometryFighter in the file inspector and yet Float.random(…) still isn’t a thing.
What have I missed?

Ah, never mind. I had Create Folder References selected rather than Create Groups in the Choose options for adding these files dialog.

Great tutorial! Thank you
