For comparison, for Go, it's "sudo snap refresh go". For Rust it's "rustup update stable". I mean, how hard would it be to properly package this stuff, and why should tens of thousands of users deal with all this manual downloading and unpacking? Assuming, of course, that Swift folks don't deliberately want to make the language unpolular, like Haskell.

I agree they should put the effort into having an easy "apt-get" solution. On the other hand, your original question was whether there is a standard way of installing Swift on Ubuntu. The answer is a very clear YES: download the latest tarball of the binaries from the Download page and unzip.

I’m kinda annoyed there’s no PPA for this, but I suspect they won’t bother shipping this in the standard repo until there’s a stable ABI

And that's fine: ship an official snap or use the Rust solution. Not doing this very directly impacts adoption. Most people won't even try to set it up.
