Tailor. A static analysis and lint tool for Swift (tailor.sh)

I would be more impressed if it were called Taylor.

Disclosure: I am one of the developers of Tailor. We would have loved to write Tailor in Swift, however (at the time of development) using the industry-standard ANTLR parser generator was the most feasible and straightforward way to develop a cross-platform tool without having to reverse-engineer the previously closed-source and proprietary SourceKit infrastructure.
