Are there any resources on using swift for shell scripting?
I’m interested in trying my hand at Swift by converting existing bash scripts into swift since bash is mostly what I am writing currently, so I figure this will at least get me started with syntax and such.

Swift doesn’t seem like a good fit for the kinds of tasks people write shell-scripts for. It’s a system/app programming language, like C/C++. Scripting languages have extremely dynamic typing, super-high-level APIs, and no separate compile/link stage.
There’s no reason you couldn’t convert some shellscripts as an exercise to learn Swift, but I don’t think you’ll find many resources out there.

I've given up on it. I find it far easier to just write a command-line app with Xcode's source support -- E

One possible advantage is that it would be relatively easy (instead of nigh-impossible) to have a shell script that interacts efficiently with the GUI.
But yes, this is mostly meant as a way for me to get a handle on the language by writing things I am familiar with and have some investment in.

Stone circles were common enough everywhere in the mountains. Druids
built them as weather computers, and since it was always cheaper to
build a new 33-Megalith circle than to upgrade an old slow one, there
were generally plenty of ancient ones around --Lords and Ladies

Thank you, that looks very promising.
I didn’t realize the list was set to “reply off list” so a message I thought I posted didn’t go through. Rather than repost it…

There's this shebang for OS X:

Interesting. I was just messing around with
#!/usr/bin/swift
And making some (albeit slow) progress.

Is there a reason to use xcrun instead of calling swift directly?

I write my scripts in a Playground to get autocompletion and instant feedback. Kind of works but sometimes I wish Playgrounds would start faster with running. And sometimes they stop working and I have to restart Xcode.

Probably not. You can just call `swift` and it will shim through to the same thing as `xcrun swift`.
IIRC, 10.9 didn't have the `swift` shim, but every OS X release since then has.
