Having spent a little time writing toy projects with Go channels, I have an increased appreciation for GCD. I think it has an amazingly low barrier to entry for dealing with simple parallelism. I can see why it's still the gatekeeper for concurrency in iOS and macOS software given how flexible the API is. (In particular, being able to pass queues to publishers in Combine is a little bit of sweetness that makes it more of a joy to use)
