After I updated my Xcode today, I got the following error
Error:PCH file built from a different branch ((clang-425.0.24)) than the compiler ((clang-425.0.27))
I know right away it has to do with the New Xcode version and Old Xcode version thing. Why? Just because some programmers won’t stop working till the last minute! LOL, if it worked flawlessly before the update. Nothing else really can explain it.
OK, here is the solution.
- On your Xcode menu, choose “Product“
- Hold “Option” key, and choose “Clean Build Folder“
- Continue working.
