Question

For the pch file I get these errors:

Answer 1

I'd like to add to the Matthew's answer:

Actually, the Framework Search Paths shouldn't be empty, but it should include only the paths to the SDK's Frameworks folders. In my case simulator worked with this path:

/Applications/Xcode.app/Contents/Developer/Platforms/_**iPhoneSimulator.platform**_/Developer/SDKs/iPhoneOS6.0.sdk/System/Library/Frameworks/

and device started working when I added this one:

/Applications/Xcode.app/Contents/Developer/Platforms/_**iPhoneOS.platform**_/Developer/SDKs/iPhoneOS6.0.sdk/System/Library/Frameworks/

Thi is for XCode Version 4.5.1 (4G1004).
