If you are seeing a lot of warnings with Xcode 7 related to linking with RadioKit, please downloaded an updated version of RadioKit (2.15.3). It corrects the issue. Xcode 7 apparently handles precompiled headers differently now in libraries and the way I was building the library was causing these warnings.
Sorry for the confusion.
Latest version of the RadioKit SDK can be found here:
