Independent Watch App - Invalid Archive - TestFlight Rejection

As a followup to issue #595 ...

With an archive built from an XcodeGen Xcode project, I ran into an issue with deploying the Watch app to TestFlight:

Using an Xcode project created via Xcode, deployment to TestFlight worked fine.

Here's the differences between the two archives' .app file:

The big differences I notice are:

• Notice the compiled Launchscreen.storyboardc under Base.lproj which Xcode adds automatically.
• As well the Assets.car file containing the app icons.

Both of these contain no source, so Xcode appears to be adding these automatically during archiving.

Here's what my project.yml looks like:

Let me know if you have any thoughts on this or how I might need to correct my project.yml file.

Start with the project.yml configuration and compare the XcodeGen archive with the working Xcode-created archive, focusing on Launchscreen.storyboardc and Assets.car in the .app bundle. Reproduce the watchOS archive and TestFlight deployment, then verify that the generated archive contains the required files and is accepted by TestFlight.
