These should be separate from the “always on” compiler diagnostics though.
I have a fairly minimal held-together-by-bandaids linter I put together:
I have hesitated to develop it much further because I didn't want to be committed to inter-process SourceKit hacking and did not yet have access to a reliable parse tree. In its current state, it's a regex-based line-by-line scan.
The rules it follows are here: https://github.com/erica/testlint/blob/master/testlint/sources/Linter.m
