👷🏻‍♂️ Switch to self-hosted M1 Mac mini runner

[phatblat]

GitHub Actions only support "X64" architecture right now, so the current solution relies on Rosetta 2. Xcode builds (at least running XCUITests) require arch -arm64 prefixed to the commands, but it seems that Swift build & test do not.

Fixes #380

TODO

• Get runner app working with scripts run outside Rosetta
• Configure code owners for .github files
• Clean up experiments
• Set the runner app to auto-launch on startup
• Move mini back into DMZ vlan

[phatblat]

Got it working tonight but need to configure the runner app to start as a service before this will be ready to merge.

[chris-araman]

Nice work! It'll be good to be ahead of the game with this.

[phatblat]

Getting farther with a shell command wrapper to force scripts to run outside Rosetta.

[phatblat]

The forced architecture for scripts worked to run brew commands in bootstrap but now it's failing on the version script, perhaps because of fetch-depth not being big enough to pick up any tags.

    - uses: actions/checkout@v2
      with:
        # Fetch tags for script/version
        fetch-depth: 0

[phatblat]

I don't think the fetch-depth is a problem. Running the version script manually on the runner in actions-runner/_work/mas/mas works fine and I can see a lot of history in the cloned repo including the v1.8.6 tag from 4 days and 5 commits ago. Must be some other environment difference, perhaps affecting the SCRIPT_PATH variable.

[phatblat]

Not sure why the version script failed that one time as the build is working perfectly now!

I want to do a little more cleanup after my experiments, set the runner app to autolaunch on startup and move the mini back into my DMZ vlan before we merge this PR.

[phatblat]

FYI, m1 is running macOS Monterey 12.1 and Xcode 13.2.1 is the default. Homebrew needs to be run as an admin so I want to add codeowners requiring admin review of any workflow changes as well as not running actions without approval. There's nothing sensitive on this box but still don't want someone to be able to trash it.

[chris-araman]

I don't think the fetch-depth is a problem.

A fetch-depth of 0 is supposed to fetch all history for all branches and tags.
