Swift Package Manager Compatibility Issue Found

I've investigated the build failure that occurs when updating to swift-protobuf v1.31.0 and identified the root cause.

Root Cause

Swift-protobuf v1.31.0 introduced a new protoc product as a binaryTarget (PR #1836). However, this triggers a known bug in Swift Package Manager where it incorrectly handles executable products that use binaryTarget.

The Error

When rules_swift_package_manager runs swift package describe --type json, it fails with:

error: executable product 'protoc' expects target 'protoc' to be executable; an executable target requires a 'main.swift' file

This occurs because Swift Package Manager doesn't properly recognize binaryTarget as a valid executable target.

Swift Package Manager Bug

This is documented as Issue #8101 in the Swift Package Manager repository: "Conflicting detection of executable targets when using a binaryTarget on an executable product"

The bug manifests as:

SPM complains that the binaryTarget is missing a main.swift file
If you add a main.swift, it then complains about having multiple executable targets

Impact on rules_swift_package_manager

Since rules_swift_package_manager depends on swift package describe to analyze package manifests, and this command fails due to the SPM bug, swift-protobuf v1.31.0 is currently incompatible with rules_swift_package_manager.

Next Steps

This update should be blocked until either:

Swift Package Manager fixes issue #8101, or
rules_swift_package_manager implements a workaround for this specific case, or
Swift-protobuf modifies their approach for the protoc target

Testing Details

Tried updating swift-tools-version from 5.7 → 5.8 → 5.10 → 6.0 → 6.1
All versions exhibit the same failure
The issue is not with our configuration but with the upstream SPM bug

The grpc_example demonstrates this issue when attempting to build after the update.
