Swift has been made available for Linux for the past four years:

I’m not sure what’s missing as far as libraries, other than UIKit.

Still, to truly compete it would need to have Windows support too. And ideally real buy-in from at least one other major tech company.
The IBM Swift Sandbox is no longer available as of January 2018.
"Support" is the kicker - I consider C# and C++ to have Windows Support because the platform vendor publishes and provides support for their own developer tools.
Do you mean that, or maybe something closer to the level of "Support" where interested parties submit improvements, and platforms are included in the CI/CD process?
It's not from Microsoft directly, but it's worth noting that LSP support for Swift is under active development. VSCode is probably currently the second-best IDE for Swift development.
edit:
If you want you can use Swift on Google Colab right now:

It's quite usable. A couple years ago, I tried Swift for Linux when it came out, and it was a dreadful experience. But now I do things with Swift in Docker containers and basically don't think about it.
There's a few things which aren't implemented (IIRC things like XML parsing support) but it's mostly things I wouldn't use or would use a library for anyway.
