Binary inclusion (#embed in Swift)

Development Compiler
5

SwiftPM 5.9 introduced an embedInCode rule.

The feature wasn't pitched or reviewed (as far as I know), and there's an open issue for type checking of larger resources.

It also uses Array rather than InlineArray, unlike the recently pitched Compile-Time Values and Section Placement Control.

For example, if your package manifest contains:

let package = Package(
  name: "…",
  products: […],
  targets: [
    .target(
      name: "…",
      resources: [.embedInCode("Example.txt")],

then a derived embedded_resources.swift file will contain:

struct PackageResources {
  static let Example_txt: [UInt8] = […]
}
