Doxygen Ignoring Some .h Files - xcode

Question

UPDATE 2: The issue seems to be stemming from the files themselves, and not the contents. I've tried, across multiple repos, duplicating the broken files from the ground up (new file, copy-paste contents, rename, etc) and they work as expected with Doxygen.
UPDATE: It seems that all of the "broken" .h files are being saved as class_.html while working .h files are interface_.html. Strikes me as related.
Trying to set up Doxygen for my Xcode project and for some reason it is ignoring the .h file in one of my repos.
The basic structure of the project is 1 central repo with a handful of private CocoaPods being pulled in either from the local copy or the external repo, depending on which is more recent. Other pods projects, when run against Doxygen, generate documentation just fine. This one does not. I've tried it with a variety of configurations (EXTRACT_ALL, EXTRACT_STATIC, etc. etc.) to no avail.
When run on the following .h file, no documentation is generated and the only thing I see is "The documentation for this class was generated from the following file:", with the .m file following; clicking on that just shows some static string constants and the imports, still no method headers.
One thing I noticed is that if I set EXTRACT_LOCAL_METHODS to YES then it works...but that would imply that I am NOT defining methods in my .h, which is definitely untrue.
Am I missing something?

Answer 1

Turns out Doxygen expects a newline at the bottom of the file.
Who knew.
