我刚刚通过 App Store 更新了 Xcode 4.5,来自我从 Apple 开发者帐户获得的以前的版本。自更新以来,我无法将任何应用程序编译到模拟器中。我可以编译到设备上,例如我的 iPhone。
我收到的错误是
fatal error: file
'/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/
Developer/SDKs/iPhoneSimulator6.0.sdk/usr/include/Availability.h'
has been modified since the precompiled header was built
1 error generated.
