iOS GPU Programming With Swift & Metal

This talk describes the steps required to implement a particle system in Swift that runs on the GPU using Apple’s Metal technology. It starts with a system containing a humble 250,000 particles and through a series of optimisations works up to a system containing over four million particles running at 40fps.
