I'm getting several errors when compiling an app on my phone. It works just fine in the simulator, but not for anything else. It started after resetting my device's settings. I've tried creating a new project, but that didn't work. Here are the exact errors.

#include <dispatch/dispatch.h>

<unknown>:0: error: could not build Objective-C module 'CoreFoundation'


This doesn't seem to be a code related issue, as this code compiled without any issue the other day. I'm just not sure how to fix it.
