#!/bin/sh

# Format Swift files with swift-format before committing
git diff --name-only -z --cached -- '*.swift' | \
xargs -0 -I {} sh -c 'swift-format -i {} || exit $?'

# If swift-format fails (returns non-zero), the commit will be aborted

# Re-add the files to stage the changes made by swift-format
git diff --name-only -z --cached -- '*.swift' | \
xargs -0 git add

# If you want to see what changes swift-format made before committing:
# git diff --cached

exit 0
