Sometimes when compiling more sophisticated iOS projects you need the IOKit headers which were removed from the iOS SDK a few versions ago. A simple workaround is to copy them from the Mac OS SDK to the iOS SDK with these commands:

sudo cp -r /Applications/ /Applications/

Sometimes you also need OSTypes.h from libkern:

sudo cp /Applications/ /Applications/

If you still have build errors check you are building for device and not simulator.
