[swift-users] How to create custom module without the package manager?

[Bee]

Sorry… I answer my own question. It need -l<module-name> argument. So, the
last command should be:

$ swiftc test.swift -lgreet

then it emitted a runnable app. I wonder why does it need an explicit
module name in the command line? While there is already an import clause
within the source file. Anyway, problem solved.

Thank you. :)
