I've updated and not had any such problems.

Have you installed / updated the command line tools for Xcode 10 ? They 
should have come as an update on their own. Does clang give the ame 
versions as below for you ?

  > clang --version
Apple LLVM version 10.0.0 (clang-1000.11.45.2)
Target: x86_64-apple-darwin17.7.0
Thread model: posix
InstalledDir: 
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
