llvm-symbolizer not found in Xcode

after install XCode,

llvm-dwarfdump llvm-objdump .. these can be found under "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/"

but llvm-symbolizer is not FOUND.

Should I install llvm by myself if I need llvm-symbolizer ?

brew install llvm
Error: llvm: the bottle needs the Apple Command Line Tools to be installed.
 You can install them, if desired, with:
  xcode-select --install

If you're feeling brave, you can try to install from source with:
 brew install --build-from-source llvm
