Unexpected error, unable to continue

[Peter-Schorn]

Describe the bug
I received an error in multiple jobs in the workflow for my RegularExpressions library (commit: c0dd27d):

name: Swift

on: [push, pull_request, workflow_dispatch]

jobs:
  build:
    name: Swift ${{ matrix.swift }} on ${{ matrix.os }}
    strategy:
      fail-fast: false
      matrix:
        os: [ubuntu-latest, macos-latest]
        swift: ["5.0", "5.1", "5.2", "5.3", "5.4"]
    runs-on: ${{ matrix.os }}
    steps:
      - uses: fwal/setup-swift@v1
        with:
          swift-version: ${{ matrix.swift }}
      - uses: actions/checkout@v2
      - name: Build
        run: swift build --build-tests
      - name: Run tests
        run: swift test

Here is the output of some of the jobs that failed:

The "Swift 5.1 on ubuntu-latest" job failed with the same error.

The "Swift 5.1 on macos-latest" and "Swift 5.2 on macos-latest" jobs also failed, although the cause of the failures may be unrelated to this action because they occurred in the "Build" step. Nevertheless, I would appreciate any help in determining the cause of the failures.

I have uploaded a zip file of the full logs on Google Drive.

Summary

Edit

I just tested the following jobs:

jobs:
  test_macOS:
    runs-on: macos-latest
    
    steps:
    - uses: actions/checkout@v2
    - name: Build
      run: swift build
    - name: Run tests
      run: swift test

  test_linux:
    strategy:
      matrix:
        image: ["swift:5.0", "swift:5.1", "swift:5.2", "swift:5.3", "swift:5.4"]
    runs-on: ubuntu-latest
    container: ${{ matrix.image }}

    steps:
    - uses: actions/checkout@v2
    - name: Build
      run: swift build
    - name: Run tests
      run: swift test

All of these competed successfully, proving that my library does compile for Swift 5.0-5.4 on Linux and swift 5.3 on macOS.

[fwal]

This seems to be the same problem as #196. Basically the linux version is incompatible with the swift version.
The reason it works in the second example is that it then is bundled with the correct linux version in the container.

[Peter-Schorn]

Is there anything I can do to make it work? I'm not sure what the best way is to test on different versions of Swift for macOS.

[Peter-Schorn]

I would only need to use this action for macOS because I can use docker for Linux.
