Which version of Xcode should we use to submit Web Extensions to App Store Connect?

Each time I attempt to upload the Safari Web Extension to App Store connect, the following error message appears:


ITMS-90301: This bundle is invalid - Apple is not currently accepting applications built with this version of Xcode.

I have tried using Xcode 12 beta 3, beta 5 and beta 6. According to https://developer.apple.com/forums/thread/657898 , beta 5 should allow submissions to App Store connect?

Is there a specific version of Xcode that I should be using to upload the Web Extension?

If it's not yet possible to upload Safari Web Extensions to App Store Connect then could you provide an estimate of when this will be possible?

Thank you!

Devs are obligated to use only release version Xcode when building/submitting for the store...no betas - right now, that would be Xcode 11.6

Be sure to option-clean build folder when going again via Xcode 11.6...you don't want any beta traces hanging around that the upload process might take repeat offense to ;)

Good luck.
I also run into the same issue.
I Started with the extension template that came with Xcode 12

And tried to build the app extension with Xcode 11.7 but now getting the following error's when trying to build it.

Code Block
Use of unresolved identifier 'SFExtensionMessageKey'

And

Code Block
Use of unresolved identifier 'SFExtensionMessageKey'


I'm pretty new building extensions in Xcode and have no idea how to build the extension on Xcode 11.
Anyone that can point me in the right direction?
