I read the link and have a pretty good understanding about how computers and file systems work but can someone "explain like I'm a decently intelligent programmer" what is different about this file system? Thanks you.

They simply started from scratch with an aim to * best support modern hardware technologies, * start from the state of the art in file systems (like ZFS and btrfs, old as they may be), and also * emphasize security.

  Sounds a lot like what Apple did with Swift.

It's apple reinventing the zfs and btrfs wheels. Which are already mature, useable and open source. Google them and see what they do well, and you might get some ideas.

  Both filesystems have copyleft licenses so that may factor into Apples decision.

This bit from 2012 by John Siracusa outlines everything “wrong” with the old file system, HFS+, and doubles as a sort of guide to what this new file system fixes. http://arstechnica.com/apple/2011/07/mac-os-x-10-7/12/ http://arstechnica.com/apple/2011/07/mac-os-x-10-7/12/
