My code folder is a sym link to a folder in my iCloud drive. The beauty is all my code will be sync'ed to cloud automatically, and the bonus is I can see this folder in every machine that syncs with the same Apple account. I believe this approach works with any cloud drive like DropBox, Google Drive, One Drive, etc.

It also means that you can destroy your ‘backup’ easily, and get your erroneous change synced to every machine that syncs with the same Apple account, destroying most copies of the affected file(s).

Unlike Dropbox, iCloud Sync doesn’t version files, so that’s not easily corrected, even if you spot the problem early.
