Question

I\'m trying to use updated SPM for Swift4 with the following Package.swift file - PackageDescription API Version 4

Answer 1

You're missing the tools version specifier in your manifest; add the following as the first line of your Package.swift:

// swift-tools-version:4.0

By default if that line is omitted, it'll default to manifest version 3 and also compiler version 3. For more information see SE-0152 or Swift Package Manager Manifest API Redesign on swift.org.
