[swiftc] Add completion spec

[0xifarouk]

Sanity checks

• My issue relates to a specific CLI completion spec (e.g. git checkout is missing options in git completion spec). If your issue is more general, please create your issue here: withfig/fig
• I have searched github.com/withfig/autocomplete/issues and there are no duplicates of my issue
• I would like to work on this.

What CLI tool does this relate to?

swiftc

Which statement makes the most sense?

This completion spec does not exist

Issue Details

Add support for the Swift compiler.

Hi! I can have a look into this if it hasn't already been done?

[0xifarouk]

@HarryET Yes, nothing has been done yet. You can check /src directory there still no swiftc.ts file. Also there is no pull request to add it.

[HarryET]

Okay, I'll try do it then. Looks likes there is loads of args to add for swift/swiftc :)

[0xifarouk]

Yeah, do you have an idea of where I can a list of all commands and arguments for it?

I've just done swiftc --help

[HarryET]

If you wanted to have a go instead I don't mind?

Yeah I know about this, I was wondering if there is a webpage that lists all of them at once.

No no, just go ahead 😅
I have just finished adding auto completion for another tool and I feel very tired.

@HarryET Good luck 😄
