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

I'm trying to use Transporter to upload my .ipa file to the Apple Store and make it available on TestFlight. I'm generating the .ipa with the command eas build -p ios --profile production. However, I'm receiving the "ITMS-90426" error in my email.

I've seen many suggested solutions for this issue, but most of them involve using Xcode. The problem is, I don't use Xcode. I only use Transporter on my Mac to upload the app, and I develop on a Windows environment.

Could you please guide me on how to generate the required files using Expo/EAS to avoid this issue?
