A proper solution to this problem is yet to be built in SwiftPM however in

It is available in a recent trunk snapshot from swift.org
Also, while passing custom arguments to swift build, escape each argument
with the prefix eg:
*`-Xswiftc -target x86_64-apple-macosx10.12` **should be:** `**-Xswiftc
-target **-Xswiftc **x86_64-apple-macosx10.12`*
