Look for a proposal about this soon! In the meantime, there's an RFC on LLVM to load "symbol graph" information for Clang-based language projects, including Objective-C: [cfe-dev] [RFC] clang support for API information generation in JSON In addition, this proposal about multi-language symbols in Render JSON is also part of the overall effort, so DocC can display information about APIs usable from both Swift and Objective-C.
