[swift-users] Help need with SR-1187

The package manager will add an implicit dependency between the test suite and the target it assumes it is trying to test. In your case, however, your package module is named PlayingCard, and your test module is name CardTests (not PlayingCardTests) so it doesn't find that dependency. This leaves it without any dependencies, and so the link fails. That the build of the individual test files doesn't fail is because we don't yet have a good way to enforce your Swift code only see what it is allowed to.

If you do:
```
$ git mv Tests/Card Tests/PlayingCard
$ TOOLCHAINS=swift swift build
$ TOOLCHAINS=swift swift test
```
then it should work.
