Build error after updating to XCode 4.6.2 Permanently deleted user 创建于 2013年05月14日 18:46 Error:PCH file built from a different branch ((clang-425.0.27)) than the compiler ((clang-425.0.28))Project builds ok in XCode. I've tried a Clean and Build, same result.Any thoughts?Dave
Weird... After a number of runs on XCode it now magically works.
It was caused by incompatible compiler caches in Xcode 4.6.1 and 4.6.2.
You may see it again on other projects but it should go away after rebuild.
