Fund: Unable to compile app with external dependencies and custom configuration

What happened?

Projects that use remote swift packages and custom configurations are not compiling. The frameworks that depend on the remote packages can't find them.

Getting warnings about configuration mismatches and then module not found errors from import statements. I'm migrating an existing project over that uses custom configs and didn't have this import issue there.

Existing xcodegen
project.yml

    info:
      path: "modules/${target_name}/Sources/Info.plist"
    sources:
      - "modules/${target_name}/Sources"

How do we reproduce it?

Here is a sample project that fails

Project.swift

let project = Project(
    name: "TestBug",
    settings: .settings(configurations: [
        .debug(name: "Development"),
        .release(name: "Nightly"),
        .release(name: "Production"),
    ]),
    targets: [
        .target(
            name: "Utils",
            destinations: .iOS,
            product: .framework,
            bundleId: "com.mycompany.myapp.utils",
            infoPlist: .default,
            sources: ["Modules/Utils/Sources/**"],
            dependencies: [
                .external(name: "Dependencies")
            ]
        ),
    ]
)

Package.swift

// swift-tools-version: 6.0
import PackageDescription

#if TUIST
    import struct ProjectDescription.PackageSettings

    let packageSettings = PackageSettings(
        productTypes: [:]
    )
#endif

let package = Package(
    name: "TestBug",
    dependencies: [
        .package(url: "https://github.com/pointfreeco/swift-dependencies", .upToNextMajor(from: "1.6.0")),
    ]
)

If you try to compile you just get

❌ /Users/billy/workspace/TestTuist/Modules/Utils/Sources/DateProvider.swift:1:8: no such module 'Dependencies'

It does compile if you remove

settings: .settings(configurations: [
        .debug(name: "Development"),
        .release(name: "Nightly"),
        .release(name: "Production"),
 ]),
