Explain Metal like I’m 5
summary
Claim: Metal is approachable and learnable quickly by sticking to its concrete pieces. Explanation covers MTLDevice, command queues, command buffers and encoders, pipeline state created from descriptors, and shader kernels in Metal Shading Language. Demo builds a Catalyst app using my_kernel inside the Alloy wrapper that reads an input texture, multiplies each pixel by an intensity uniform, writes an output texture and dispatch threads equal to the texture size. Demo runs and shows a working brightness filter; Catalyst needs explicit texture sync, iOS does not.
