If I'm not interested in Apple products, why would I bother with Swift? Are there any free software projects that are written in Swift? Why wouldn't something like Golang be better, since it's more widely used in Linux/FLOSS world? To me, Swift seems like a better Objective-C but it's still pretty much only usable on crapple ecosystem(?).
I just read:
https://docs.swift.org/swift-book/documentation/the-swift-programming-language/guidedtour/
and I didn't find anything particularly exiting. On the other hand, Golang is more popular and it has CSP-style concurrency which is great because it's simple.
