How to write apps for iOS 12 in Xcode 11?

Excluding files in Swift Packages

To exclude entire sections of a file, I can use macros to target platforms such as #if os(iOS) || os(watchOS). Is there a way to do this in Package.swift, or another way to target a few files for specific platforms in Swift Package Manager?
