a8c2e29868
this migrates our current swift code to version 5 and 4. building is support from 10.12.6 and xcode 9.1 onwards. dynamic linking is the new default, since Apple removed static libs from their new toolchains and it's the recommended way. additionally the found macOS SDK version is printed since it's an important information for finding possible errors now. Fixes #6470
