“value of type ____ has no member 'help' ” after update to latest stable XCode release

问题

• MacOS: 11.0 Beta (20A5384c)

• Xcode: 12.0.1 (12A7300)

After update from Xcode beta to release version I see lot of errors like:

"value of type ____ has no member 'help' "

Is it was deprecated from release build of Xcode 12 ?

On the XCode 12 beta works well.
