That's neat!

But how is everyone testing their Swift codebases? We've found the story around testing to be... lacking. The [docs](https://developer.apple.com/documentation/xctest) on the subject are pretty bare and don't offer strategies for mocks, stubs, reporting, code coverage, etc.

And good luck if your app uses a Network Extension... those must be tested on a live physical device due to the signing restrictions!

On that note, does anyone know of a good physical device CI service that supports both iOS and macOS devices?
