No, no, I don't object to your comment. You're just not the only person I've seen making the comparison to Golang, and so I had a big comment bottled up. :)
Including me, I think some syntaxes of Switft look like Go, while they actully don't share the same vision. Go tries to be a language great for system programming so it introduces channels, interfaces. But Swift want to help GUI programming and it needs the whole class system but without crazy stuffs like channels.
But for others aspects that are not related these two(class system, concurrency), I would say they look quite similar.
I don't know what this means. I've used Golang successfully for USB drivers, emulators, web and database servers, testing tools, a debugger, and cryptography. It seems evidently suited for systems programming as it stands.
Someone is always going to be out there saying that any language isn't ready for prime time because it lacks feature-X.
