how to run SwiftLint on uncommitted files for m1

Question

I found this shell script

# Run SwiftLint
START_DATE=$(date +"%s")

SWIFT_LINT=/usr/local/bin/swiftlint

# Run SwiftLint for given filename
run_swiftlint() {
    local filename="${1}"
    if [[ "${filename##*.}" == "swift" ]]; then
        #${SWIFT_LINT} autocorrect --path "${filename}"
        ${SWIFT_LINT} lint --path "${filename}"
    fi
}

if [[ -e "${SWIFT_LINT}" ]]; then
    echo "SwiftLint version: $(${SWIFT_LINT} version)"
    # Run for both staged and unstaged files
    git diff --name-only | while read filename; do run_swiftlint "${filename}"; done
    git diff --cached --name-only | while read filename; do run_swiftlint "${filename}"; done
else
    echo "${SWIFT_LINT} is not installed."
    exit 0
fi

END_DATE=$(date +"%s")

DIFF=$(($END_DATE - $START_DATE))
echo "SwiftLint took $(($DIFF / 60)) minutes and $(($DIFF % 60)) seconds to complete."

Which worked pretty well till I updated my computer to the new M1 chip.

According to this blog https://www.anotheriosdevblog.com/installing-swiftlint-on-a-m1/ We should change the location of the path. I suspect it has something to do with the location SwiftLint is installed:

However I'm not to familiar with home-brew or shell script to get it working.

Answer 1

Home-brew location has changed on the new Macs.

changing

SWIFT_LINT=/usr/local/bin/swiftlint

to

SWIFT_LINT=/opt/homebrew/bin/swiftlint

Fixed the issue
