inconvenient in the swiftsupport folder

Good night, when trying to upload my app with apple connect and with xcode 11.3.1 and after the initial review apple throws me this message: Invalid Swift Support - The SwiftSupport folder is empty. Rebuild your app using the current public (GM) version of Xcode and resubmit it.


We are not using a beta version, please has anyone had this same problem? thanks
