Review if there are big files (no git lfs needed)

git rev-list --objects --all |
  git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)' |
  sed -n 's/^blob //p' | awk '$2 >= 103809024' |
  sort --numeric-sort --key=2 |
  cut -c 1-12,41- |
  $(command -v gnumfmt || echo numfmt) --field=2 --to=iec-i --suffix=B --padding=7 --round=nearest

For future files

# Install git lfs in the current repo
git lfs install
# Add the following tracks
git lfs track "**/*.framework/**"
git lfs track "**/*.xcframework/**"

git add .gitattributes
