For the pch file I get these errors:

Answer 1

got this problem with xcode 5 (developer preview). i tried everything, including these answers - Availability.h, UIKit.h, etc not found but nothing works.

my fix was reinstalling xcode (downloading again from developer portal and replace the old one)
