Invalid SwiftSupport XCode 11

I had a working ReactNative app and I was able to upload it to AppStore with XCode 10.3. When I swicthed to XCode 11.x (I tried all versions up to 11.5 without any build changes), I am getting an email from Apple after submission:

Dear Developer,We identified one or more issues with a recent delivery for your app, "***". Please correct the following issues, then upload again.ITMS-90424: Invalid Swift Support - The SwiftSupport folder is empty. Rebuild your app using the current public (GM) version of Xcode and resubmit it.

I tried:

• setting ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES to YES and NO
• setting Swift version to 5
• setting STRIP_SWIFT_SYMBOLS to YES

And nothing worked. I have read a lot of threads about such error, but nothing helped me.

Indeed, SwiftSupport folder is not present in archived app, while it is there when I archive it with XCode 10.3Does anybody have any idea what else can I do?
