Cannot run `danger-swift pr` - JIT session error: Symbols not found

[viniciusml]

Hey all!

I've been trying to run danger-swift pr locally and I get an error JIT session error: Symbols not found. Could someone help me with that, please?

This is how my Package.swift file looks like:

// swift-tools-version:5.7
import PackageDescription

let package = Package(
    name: "Eigen",
    dependencies: [
      .package(url: "https://github.com/danger/swift.git", from: "3.15.0")
    ],
    targets: [
        // This is just an arbitrary Swift file in our app, that has
        // no dependencies outside of Foundation, the dependencies section
        // ensures that the library for Danger gets build also.
        .target(name: "eigen", dependencies: [.product(name: "Danger", package: "swift")], path: "Artsy", sources: ["Stringify.swift"]),
    ]
)

Error after running `swift run danger-swift pr PR-URL`

Thanks in advance!

Hey @viniciusml , seems like this was a Swift 5.7 bug. I tried with an older version and more recent one like 5.8.1 and it works fine for me.

@StefanLage you're right! 🎉 It works for me as well. thanks for the heads up
