Expected behavior

I am able to successfully run the buid_app target both from the CLI and from xcode. I expect to be able to successfully generate the preview.

Versions

  • Bazel: 5.3.0
  • rules_xcodeproj: 0.7.1
  • rules_apple: 1.1.1
  • rules_swift: 1.1.1

Does this still fail in Xcode 14? Also, which version of swift-composable-architecture are you using?

Since this is a Swift compiler crash 😬 I will need a full reproducer instead of just the BUILD file to be able to debug this. You can email that to me you would rather not post it publicly, if you can't make a sanitized public repro.

I tried upgrading to Xcode 14. Error still persists. I am using 0.39.1 of swift-composable-architecture. Here is the call to spm_repositories in the WORKSPACE file

    spm_repositories(
        name = "swift_pkgs",
        platforms = [
            ".macOS(.v10_15)",
        ],
        dependencies = [
            spm_pkg(
                url = "https://github.com/apple/swift-log.git",
                exact_version = "1.4.2",
                products = ["Logging"],
            ),
            spm_pkg(
                url = "https://github.com/pointfreeco/swift-composable-architecture.git",
                exact_version = "0.39.1",
                products = ["ComposableArchitecture"],
            ),
            spm_pkg(
                name = "Bow",
                url = "https://github.com/bow-swift/bow.git",
                exact_version = "0.8.0",
                products = ["Bow", "BowEffects"],
            ),
            spm_pkg(
                url = "https://github.com/grpc/grpc-swift.git",
                exact_version = "1.7.3",
                products = ["GRPC"],
            ),
            spm_pkg(
                url = "https://github.com/hyperoslo/Cache",
                exact_version = "6.0.0",
                products = ["Cache"],
            ),
        ],
    )

I'll work on generating a full report of the compiler crash and send it to the email address on your Github profile. Thanks!

I'm going to close this for now. If you can provide self-contained reproduction project then I can reopen this and debug it. Recent releases, and even main, have improved SwiftUI Previews support though, so maybe this is already fixed for you.
