Swift Packages: Linux Compatibility Testing

As the Swift on Linux and Swift Package Manager ecosystems mature, many authors of Swift packages want to enable their packages on Linux as well as Apple platforms. The growth of Server-Side Swift makes Linux an important target for many packages.

The first step is to run a package's unit tests on Linux, to verify it behaves as expected.

Enabling unit tests on Linux

Because Swift on Linux does not use the Objective-C runtime, the dynamic features that the XCTest unit testing framework uses to automatically discover testcases are not available.

	COUNT=$(git grep NSUnimplemented $commit | wc -l)

	echo "$commit, $DATE, $COUNT"
done

Foundation

As a core library which underpins many Swift packages, the Foundation project is a key part of the overall swift.org ecosystem. Foundation provides a baseline of fundamental types and functionality which is useful to all applications and can be implemented on a broad range of platforms and operating systems.

Since Swift became open source in 2015 the community has worked together to improve the implementation of Foundation on Linux and the project has progessed significantly.

// You have an enumeration:

enum Enum {
    case foo(Int)
    case bar(String)
    case qux(Int)
}

// And you have an array of them:
