After submitting my app to the Apple App store I get an email that says:

Invalid Swift Support - The SwiftSupport folder is missing
I have not mucked with Swift at all in my Flutter project, only Objective-C, so I don't want Swift.

This overflow says to set "Embedded Content Contains Swift Code" to NO in Build Options.

I haven't found that option yet. I do have one called, "Always Embed Swift Standard Libraries" and that is already set to "NO"... Not sure if that's what is being referred, but atm don't have a way to fix this issue.

I also tried "export for App store", and used Application Loader to upload the file, same error.

Steps to Reproduce

Submit app to app store.
