Getting a build failure trying to run appledoc through Xcode on my project. Previous to this issue, building my documentation did not have any issues, and have been built successfully.

It's been a while since I've built my documentation so I don't really know what kind of change I might have made that has caused appledoc to run into this issue. The failure message is as follows:

2014-02-23 13:59:24.183 appledoc[2598:507] -[GBEnumConstantData methodSelector]: unrecognized selector sent to instance 0x40104d440
appledoc version: 2.2 (build 961)

Oops, something went wrong...

It seems like there might be something going wrong when trying to parse documentation around an enum constant, but I don't really know what to look for. Does anyone have experience with errors like this that can shed some light on it?

It probably gets tripped over some source - increase verbosity with --verbose 6 to identify the source of the problem.


Let me know in which file it trips and please attach the sourcecode. Perhaps it is just a syntax issue.—

So I was able to fix my issue and I think I might have found what was causing the problem. First, however, I just want to say that setting verbose 6 put out way too much stuff and the log file seemed to get cut off without giving me a clue where the problem was happening. Using verbose 5 instead provided enough information that I was able to pinpoint my issue.

The problem seems to have been that I was referencing a different enum type within the documentation on a enum type value. That is, within the documentation for a specific enum value (e.g. AnEnumTypeValue of type AnEnumType, defined using NS_ENUM(NSInteger, AnEnumType)), another enum type was mentioned (e.g. AnotherEnumType). Removing this mention stopped appledoc from failing.

It should be noted that it was only when mentioning the overall type in the documentation that appledoc failed to build. If I were to mention a specific enum type value (e.g. AnotherEnumTypeValue of type AnotherEnumType), the build would complete without errors.
