FBSDKCorekit.h, FBSDKCopying.h file note found using Cocoapods : <p>For some odd reason after adding an unrelated pod I have been receiving an error message during the build process that indicates FBSDKCorekit.h, FBSDKCopying.h and FBSDKButton.h files are not found. I have followed countless suggestions changing properties in the projects build settings based on suggestions I've found on stackoverflow; however, none seem to work. </p>

<p>I am using Cocoapods so I attempted to uninstall and reinstall it as well as the pre-release version. I cleared the pod cache as well as removed the actual pods folder and podfile.lock and the xcworkspace and re-installed the pod into the project; however, I still recieve the error.</p>

<p>I also removed the project cache and rebuilt it...</p>

<p>Any assistance would be appreciated</p>
