The version of protoc-gen-swift is mismatched between the macOS and Linux versions of the latest release (1.23.0)

[ezzatron]

Describe the bug

When downloading archives from the 1.23.0 GitHub release, the included version of protoc-gen-swift differs between the macOS and Linux versions:

• The Linux version (https://github.com/grpc/grpc-swift/releases/download/1.23.0/protoc-grpc-swift-plugins-linux-x86_64-1.23.0.zip) contains protoc-gen-swift 1.26.0
• The macOS version (https://github.com/grpc/grpc-swift/releases/download/1.23.0/protoc-grpc-swift-plugins-1.23.0.zip) contains protoc-gen-swift 1.25.1

This is leading to us seeing different generated output under CI vs. when run locally.

To reproduce

See this reproduction repo / workflow run: https://github.com/ezzatron/grpc-swift-binary-version-repro/actions/runs/10804792826

Alternatively, set up a GitHub repo with this workflow, and run it to check the version difference:

on:
  push:

jobs:
  linux:
    runs-on: ubuntu-latest
    steps:
      - run: |
          curl -sSL https://github.com/grpc/grpc-swift/releases/download/1.23.0/protoc-grpc-swift-plugins-linux-x86_64-1.23.0.zip -o protoc-grpc-swift-plugins.zip
          unzip protoc-grpc-swift-plugins.zip
          ./protoc-gen-swift --version
          ./protoc-gen-grpc-swift --version

  macos:
    runs-on: macos-latest
    steps:
      - run: |
          curl -sSL https://github.com/grpc/grpc-swift/releases/download/1.23.0/protoc-grpc-swift-plugins-1.23.0.zip -o protoc-grpc-swift-plugins.zip
          unzip protoc-grpc-swift-plugins.zip
          bin/protoc-gen-swift --version
          bin/protoc-gen-grpc-swift --version

Expected behaviour

The version of protoc-gen-swift should be the same across all architectures for a given release.

Thanks for filing this, it should be resolved by #2053

@glbrntt I tried to verify that this was fixed in 1.24.0, but it seems like the normal archives are completely missing from the GitHub release: https://github.com/grpc/grpc-swift/releases/tag/1.24.0

I also tried with 1.23.1, but ran into this error with the Linux version:

./protoc-gen-swift: symbol lookup error: ./protoc-gen-swift: undefined symbol: $s10Foundation15ContiguousBytesMp

(see https://github.com/ezzatron/grpc-swift-binary-version-repro/actions/runs/11228796504/job/31213284514#step:2:11)

[glbrntt]

Apologies, 1.24.0 was incorrectly tagged. Try 1.24.1 https://github.com/grpc/grpc-swift/releases/tag/1.24.1

---

This comes from protoc-gen-swift which is from the SwiftProtobuf project and is unrelated:

./protoc-gen-swift: symbol lookup error: ./protoc-gen-swift: undefined symbol: $s10Foundation15ContiguousBytesMp

$s10Foundation15ContiguousBytesMp demangled is "protocol descriptor for Foundation.ContiguousBytes" which is a bit surprising. I'd suggest try to reproduce that issue in isolation and opening an issue against the SwiftProtobuf repo.

Thanks! Looks to be resolved in 1.24.1:
