My two iMacs started giving me File Shield Alerts today on the file:
libswiftDispatch.dylib
in /Applications/Xcode.app/Contents/Frameworks
This library is used in many Mac apps.  I found several people complaining about it at:
Home - 1Password Community

Is this a false positive?

Thanks,

Rick

Too late! Message not longer on screen. I uploaded the file to VirusTotal.com and ran an analysis on it. Only AVG and Avast detected a virus. Given that and the fact that the file is a signed Apple library, it would seem there is a bad definition in your last virus definitions giving a false positive. 

BTW, OS is High Sierra and AVG is latest Mac version.
