Assistance Needed: App Submission Issue (ITMS-90426)

Hello,

We submitted our app on TestFlight, but received an automated response with the following error:

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

Our app is developed entirely in Objective-C, and we’re unsure why it’s looking for SwiftSupport. Despite attempting several potential solutions, the error persists.

Could someone please assist us with understanding why this is happening and advise on how to proceed with the submission? Any guidance would be greatly appreciated.

Thank you for your help.

Here's a recent thread where I'm discussing the most common reason apps receive this error with another developer.
