Don't like this since it's just asking for code conflicts with any other developer's code and their own build number changes.

I prefer setting the number on the CD pipeline. It's one less file to have changes in git.

I disagree that a timestamp is a “build number”. Additionally, injecting dates/times into builds is bad juju from a reproducibility perspective.

Preferably you'd have a build server where you can use the build number. I use this to build my macOS application in GitHub Actions.

    [[ $GITHUB_REF_TYPE = "tag" ]] && MARKETING_VERSION=$GITHUB_REF_NAME || MARKETING_VERSION=$(git rev-parse --short HEAD)
    echo "Building $MARKETING_VERSION ($GITHUB_RUN_NUMBER)"
    agvtool new-version -all $GITHUB_RUN_NUMBER
    agvtool new-marketing-version $MARKETING_VERSION
Non-tagged build gives me "Building a3d4743 (54)", tagged build gives me "Building 0.3.1 (55)".

Agreed, CI-managed build numbers are a good way of handling this. I've done the same thing at my past handful of jobs.
