Xcode 12.2 & Big Sur: Source editor extensions have vanished

After upgrading to Xcode Version 12.2 (12B45b), all my extensions are no longer showing, in the editor menu.

Extensions are present in system preferences and selected.

Anyone else experiencing this?

So, apparently Source Editor extensions now need to link / embed & sign the XcodeKit framework.

After updating my extension as such, it now works.

Yes! I, too, am experiencing this. Have tried uninstalling/reinstalling, but no joy. They're enabled in Extensions in System Preferences. I've reported this to Apple.

I've got the same problem and have reported it to Apple via the Feedback Assistant.

If anyone else experiences the same issue it's a good idea to report it as well because Apple actively uses the number of independently raised, but related Feedback Assistant tickets to determine what to prioritize fixing.
