Some hints for the troubleshooting process: Xcode links to the framework both via the file navigator and via the Framework Search Paths entry of Build Settings. It is possible that they don’t both point to the same thing. I would probably start by searching my system for RapidEars.framework and removing all copies of it found, making sure that the app project breaks, removing the RapidEars.framework entry from Framework Search Paths, and then downloading your RapidEars 2.5 framework from the licensee site and installing it to the app project fresh. At that point you should see the line of logging stating the version number of RapidEars.
