Can Swift 5 be added?

[Coeur]

7 years ago, Swift 4 was added to TIO: 3289ff0
Can we get a recent Swift 5 now, like Swift 5.9?

Hum, @DennisMitchell didn't do any commit since 2019, so I'm not sure how this project is maintained now.

@pavelbraginskiy and @AndrewSav for inquiry on the maintenance status of TIO?

Haven't heard from Dennis in years. He seems to be keeping the site up, but we can't contact him.

His last public activity on CodeGolf is a comment on Nov 4, 2019:

His last public activity on GitHub is a commit on Nov 19, 2019:

So I'm afraid, something may have happened to him.

"Dennis Mitchell" being a cartoon character, it's hard to search for him:

Ah, I found this. His activity stopped soon after stepping down from CodeGolf moderation:

I mentioned this issue to Dennis, unfortunately, at the moment it is unclear what or when can be done. Many software packages depend on up to date libraries which come from package feeds that are not updated for old operating systems such as one TIO runs on currently, so any update would entitle an entire execution environment update. Whether or not it's practical to fit into Dennis current life remains to be seen. Sorry I do not have better news.
