ITMS-90426: Invalid Swift Support - The SwiftSupport folder is missing

[c100k]

Have you guys been able to publish your app on the App Store after adding this library ?

On my side, everything builds and works correctly. But when I publish the app to TestFlight (iOS), I get the following email from Apple:

Dear Developer,

We identified one or more issues with a recent delivery for your app, "AppName" 1.0 (5). Please correct the following issues, then upload again.

ITMS-90426: Invalid Swift Support - The SwiftSupport folder is missing. Rebuild your app using the current public (GM) version of Xcode and resubmit it.

Best regards,

The App Store Team

Is there anything more that needs to be done in the setup phase ? I couldn't find anything on the Get Started page.

When I inspect the .ipa built, there is libswift_Concurrency.dylib added in AppName.ipa/Frameworks. I suspect the issue comes from this.

Well... Changing ad-hoc to app-store when building the app resolved the issue.
