ClangKit provides an Objective-C frontend to LibClang.
Source tokenization, diagnostics and fix-its are actually implemented.
ClangKit is intended to be used as a private framework, in an application's bundle.
Possible applications includes:
The project actually supports parsing C, C++, Objective-C and Objective-C++ source code.
The project is not yet compatible with iOS, but everything should be fine, as LibClang is actually compiled as a static library.
ClangKit is published under the terms of the BOOST license.
