I compiler swift in macOS 10.15.4 , Xcode 12.2, swift version swift-5.3.1-RELEASE
build-script --release-debuginfo --debug-swift --Xcode
but I found this error:
but none of these is a common dependency of the other(s). This is not
allowed by the Xcode "new build system".
how can I change "build system" whith the build commond string?
