Unsupported Xcode or SDK Version when Uploading with Xcode 12 Beta 3

Also hitting this. Any updates from Apple?

Same issue here. After archiving I have validated the app and Xcode says that there is no problems. But after uploading I get this error message on mail:

ITMS-90562: Invalid Bundle - The app submission can not be successfully recompiled from bitcode due to missing symbols during linking. You can try to reproduce and diagnose such issues locally by following the instructions from: https://developer.apple.com/library/archive/technotes/tn2432/_index.html

I have also followed the steps here, but all fine - "Rebuild from bitcode" works as it should without any error messages.

Created a feedback for it as well, FB8136576.

Worked for me yesterday again. Haven’t tried it today.
I assumed it was resolved.

Hi,
I am also facing "Unsupported Xcode or SDK Version when Uploading with Xcode 12 Beta 3" error.Is this fixed?

I am hitting this now as well. Xcode 12 beta 5, iPhone XS 14 beta 6

ITMS-90562: Invalid Bundle - The app submission can not be successfully recompiled from bitcode due to missing symbols during linking. You can try to reproduce and diagnose such issues locally by following the instructions from: https://developer.apple.com/library/archive/technotes/tn2432/_index.html

Following instructions installs and runs fine on my phone (with and without specific app thinning)

Just a quick update - updating to Xcode 12 beta 6 revealed a function signature change in the widget api that Xcode beta 5 was fine with. Fixing this signature solved the 'missing symbols during linking' issue on upload.
