Compile swift module/framework/library without xcode

Question

Writing a Swift framework, I'm wondering, can I compile this without using Xcode. I tried 'swift' with the -module options, but the 'swift' command does not seem to produce any output no matter what I do. 'swiftc' with the -parse-as-library gives an 'Undefined symbol _main' error

So, how can I compile a swift library without Xcode?

Answer 1

As of Swift 2.2 you can use swiftc to compiles a swiftmodule directly from the command line using the -emit-module flag like this:

$ swiftc -emit-module MyClass.swift
$ ls
MyClass.swift
MyClass.swiftdoc
MyClass.swiftmodule

Use the --help flag to see the full list of options. Also see Creation of pure Swift module blog post for a more complete tutorial.
