Code linting for Objective C

Question

Are there any code linting tools for ObjectiveC?

Answer 1

There is also the commercial tool FauxPas, which catches a lot of code smells, but also stuff like unused graphics, translation format argument mismatch, etc.

It’s not super cheap, but I‘m a happy user. There's a time-limited trial version available, which is fully functional, as far as I know.
