Use R.swift for resources in your own Swift package.

How ?

  1. This is a plugin for Swift Package Manager, which supports plugins since Swift 5.6, therefore the proper swift tools needs to be used

    // swift-tools-version:5.6

  2. You need two dependencies, R.swift.Library as usual, but also R.swift.Plugin

    dependencies: [
        .package(url: "https://github.com/mac-cain13/R.swift.Library", from: "5.4.0"),
        .package(url: "https://github.com/quentinfasquel/R.swift.Plugin", from: "5.4.0")
  3. Your target needs to link with R.swift.Library and use the plugin

    targets: [
            name: "YourTarget",
            dependencies: [.product(name: "RswiftDynamic", package: "R.swift.Library")],
            resources: [
                .copy("someImage.png") // Resource example
            plugins: [.plugin(name: "RswiftPlugin", package: "R.swift.Plugin")]
  4. Use R.swift like before :

    let image = R.image.someImage()


This plugin may not be bullet-proof since it was barely tested. It is awaiting to become officially supported by the official R.swift, here is what to know about how it works :

  • The SPM plugin uses an executable variant of the official R.swift. It is currently hosted through a github release built from this branch.

  • It uses --accessLevel public so that the resources of a package, and mostly R.validate(), are accessible in the package’s test target.

  • The executable is slightly big (~ 24Mb) since it carries along a dependency on Swift Package Manager’s own package model

  • Your feedback is welcome!
