title: Xcode 6 - Unknown type name 'NSString' / Expected identifier or '('
body: <p>When I am running my project in Xcode 6, I am having many weird errors.</p>
  
  <pre><code>Parse Issue - Unknown type name 'NSString'
  Format argument not an NSString
  Could not build module Foundation
  Could not build module QuartzCore
  </code></pre>
  
  <p>All of these errors occur in Apple's header files such as: CAMediaTiming.h, NSObjCRuntime.h,NSZone.h,NSObject.h, CALayer.h, etc.</p>
  
  <p>Unfortunately, the answers in here: <a href="https://stackoverflow.com/questions/11857765/ios-parse-issues-in-nsobjcruntime-nszone-and-nsobject">ios - Parse Issues in NSObjCRuntime, NSZone, and NSObject</a> did not work for me.</p>
  
  <p>How do you recommend I fix these errors?</p>
