How can I generate code coverage for Swift packages on Linux or OS X?
<p>I am looking for a way to generate code coverage for a Swift package created using Swift Package Manager. On OS X I can achieve this using Xcode after running <code>swift package generate-xcodeproj</code> and running the test suite under Xcode at which point I have the standard coverage tools available to me.</p>

<p>Are there any tools out in the wild for that allow this to happen on OS X and Linux?</p>
