from where CopySwiftLibs gets executes and copies standard swift libraries? is there a way to avoid it?

From where CopySwiftLibs gets executed? I am trying to avoid getting libswift*.dylib which gets copied through CopySwiftLibs, I see an option in xcode, which is “Always Embed Swift Standard Libraries”, but it is set to “No”, but still libswift libraries gets copied to Contents/Frameworks/ of app. Is there a way yo avoid it?
