FYI, I just provided a PR for this. If you want to use it now, you can use my repo ( ratranqu/PathKit). It works with the latest swift 3.0 dev snapshot from 2013/03/24.

@saulius: Hum... I didn't touch the Linux bits as no running Linux vms with latest Dev branch. Let me have a look when I hv some time. Can you share which version of swift you are running please?

Thx.

[sauliusgrigaitis]

@ratranqu I use latest DEVELOPMENT-SNAPSHOT-2016-03-24-a

[ratranqu]

@sauliusgrigaitis, I've just done a commit on my local copy (and pushed to PR). Can you confirm you are sorted now?

[sauliusgrigaitis]

@ratranqu thanks, looks like it works at least on Linux!

Support for Swift 3 has been added in PathKit 0.7.0.
