Chapter 1: Hello, Metal!

As I read this book, I summarize what I think is wrong. If you think my comments are wrong then please let me know. We can dicuss more and update your opinion.

The pipeline state

When this book creates a pipeline state, they manually set the output pixel format like below.

pipelineDescriptor.colorAttachments[0].pixelFormat = .bgra8Unorm

This is fine but the output pixel format of view isn't always .bgra8Unorm. It can be .rgba8Unorm or other formats. Thus we need to get this information from a view like below.

pipelineDescriptor.colorAttachments[0].pixelFormat = view.colorPixelFormat;
