.build/x86_64-apple-macosx/debug/Danger.build/Danger-Swift.h' not found

I have problems setting up danger-swift in my iOS project.

I followed the steps in the readme

npm install -g danger
brew install danger/tap/danger-swift

I created a DangerCompileDummy.swift file in the Sources/DangerDependencies folder, and created the following Package.swift following the example in the README.

// swift-tools-version:5.3
import PackageDescription

let package = Package(
  name: "DangerDependencies",
    products: [
      .library(name: "DangerDeps", type: .dynamic, targets: ["DangerDependencies"]),
    ],
    dependencies: [
      .package(name: "danger-swift", url: "https://github.com/danger/swift.git", from: "3.0.0")
    ],
    targets: [
      .target(name: "DangerDependencies", dependencies: ["danger-swift"], sources: ["DangerCompileDummy.swift"]),
    ]
)

i explicitly had to name the package danger-swift, otherwise i get the error dependency 'Danger' in target 'DangerCompileDummy' requires explicit declaration....

However i get the confusing error

* Build Completed!
Starting Danger PR on my-pr
../my-project/.build/debug/Danger.build/module.modulemap:2:12: error: header '../my-project/.build/x86_64-apple-macosx/debug/Danger.build/Danger-Swift.h' not found

I don't know what causes it. All i can see is that this header file referenced in the modulemap is really just not there. From all i can see now, my setup is consistent with the one in the readme.

Environment:

• XCode 12.5
• MacOS BigSur 11.4 (20F71)

Does the machine has an M1 processor?

[falcowinkler]

No I have this machine: MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports) 2 GHz Quad-Core Intel Core i5

Hey, so I looked a little bit at the issue, given you are installing the project with brew you don't need a Project.swift, does removing that file helps? Another alternative is to not use brew install danger/tap/danger-swift and use swift run danger-swift ci (in the folder with the Package.swift) instead.

[falcowinkler]

you mean just running danger-swift ci ... without the swift run prefix right? i tried it but it leads to the same error. I think the error happens when the Dangerfile.swift is evaluated... i'm still not sure why it happens. We switched now to another solution in the team, so feel free to close this. If you want to figure it out i'm happy to provide more info tho.

@f-meloni Hey I'm also seeing this issue and we do have an M1 Mac Mini for our CI.

I know Homebrew updated their installation path for M1 machines, but do you know of a way to fix it?
