How do I debug a Swift dependency tree analysis?

[alexvbush]

Hi, love the gem, works like magic with a brand new Swift project but when I run the script for an existing production codebase I get the following output in origin.js

var dependencies = {"links":[],"links_count":0,"objects":{}}

Seems like nothing gets parsed and I wonder why and how would debug this?

Also is there a way to run it for an arbitrary folder with Swift code?
