Got it working with this instead!

git filter-branch --index-filter \
    'git ls-files -s | sed -E "s/( [a-z0-9]{40} 0.)/\1first\//" |
    GIT_INDEX_FILE=$GIT_INDEX_FILE.new \
    git update-index --index-info &&
    mv "$GIT_INDEX_FILE.new" "$GIT_INDEX_FILE"
    ' --tag-name-filter cat -f -- --all

I also had a problem with empty git commits. Therefore I added a check for those situations

git filter-branch --index-filter \
    'git ls-files -s | sed -E "s/( [a-z0-9]{40} 0.)/\1ios\//" |
    GIT_INDEX_FILE=$GIT_INDEX_FILE.new \
    git update-index --index-info &&
    if [ -f "$GIT_INDEX_FILE.new" ]; then mv "$GIT_INDEX_FILE.new" "$GIT_INDEX_FILE"; fi
    ' --tag-name-filter cat -f -- --all
