I've been having an issue compiling my project after attempting to install the Facebook SDK to the project. I've reverted the code back to it's previous state, however I'm still getting error messages related to "ProcessPCH". I've checked the Target settings and still cannot find any solution to this issue.
The error code is shown below:

If anyone has a solution for this, it would be greatly appreciated.
The issue is now fixed. While I'm not proud with myself for causing the issue, I am very glad it is solved.
In my case, I had accidentally commented out the @end of my AppDelegate header file, causing the XCode project to fail building entirely.
I'm still very unsure as to why it was then stating my failure was related to a file within MKNetworkKit, but I can only suggest that you check ALL of your files for common mistakes like this if cleaning the build / derived data does not work. Reinstalling XCode is definitely not an ideal solution.
