Hi, I have a problem with making a swift playgrounds app walkthrough. I followed the steps exactly and modified my Package.swift a bit (in the targets section):

.executableTarget(name: "App", dependencies: ["Guide"], path: "App"),

        .target(

            name: "Guide",

            path: "Guide",

            resources: [

            .process("Guide.tutorial"),

            ])

Now when I open the project in Playgrounds I get this error: public headers ("include") directory path for 'Guide' is invalid or not contained in the target

Any help would be appreciated.

Thanks

I am having this error as well. I'd love to know if you ever found a solution!

Same.

I'm having essentially the same issue while trying to compile Metal files:

// swift-tools-version: 6.0
import PackageDescription

let package = Package(
    name: "BaseMetal",
    platforms: [.macOS(.v14)],
    targets: [
        .executableTarget(name: "BaseMetal"),
        .target(
            name: "BaseMetalShaders",
            path: "Sources/Shaders",
            resources: [
                .process("Canvas.metal"),
                .process("Shader.metal")
            ]
        )
    ]
)

My tree looks like this:

.
├── Package.swift
└── Sources
   ├── BaseMetal
    │   ├── Main.swift
    │   ├── Metalic.swift
    │   └── Renderer.swift
   └── Shaders
         ├── Canvas.metal
         └── Shader.metal

This is the exact error message:

❯ swift run
error: 'basemetal': public headers ("include") directory path for 'BaseMetalShaders' is invalid or not contained in the target

How can this not work??
