Hyphen or Space?

I'm coming from Linux experience and have been investigating whether I can use Swiftlang for general scripting instead of Bash.
I came across this repo, but the documentation is very confusing as you write "swift sh" in most places.

I'm using 5.10.1, and swift-sh builds without issue.
I copy .build/debug/swift-sh to /usr/local/bin as I would expect

I then use the Promise Example as follows:

$ cat script 
#!/usr/bin/env swift-sh
import PromiseKit  // @mxcl ~> 6.5
print(Promise.value("Hi!"))

Please note I use "swift-sh" as based on my Linux experience, "swift sh" does not work.
My script above works fine, and I am very impressed.

Are these "swift sh" un-noticed typos, or is there something else I should know.

swift is a launcher. swift foo will cause swift to search for swift-foo in the PATH and launch that if it finds it. So both work. Sorry if the docs are confusing.
