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!
