[swift-users] Build from command line using swift 4 toolchain

[Halen Wooten]

Hi,

I downloaded the Swift 4 toolchain from swift.org and change my
setting in Xcode. However, when I build xcode projects from the
command line it's still using Swift 3.1. How can I instruct the
command line tools to build with Swift 4?

Thanks for the help,

Halen
