error: unable to load standard library for target 'arm64-apple-ios10.0-simulator'?

Question

I updated my Xcode but not able to build. It\'s failing with:

:0: error: unable to load standard library for target \'arm64-appl

Answer 1

Resetting all environment variables is not a solution, since that will also unset SSH keys for instance, which will cause cloning to fail in case SSH authentication is used.

However, the only problematic environment variable is LLVM_TARGET_TRIPLE_SUFFIX, so unsetting that solves the problem.

unset LLVM_TARGET_TRIPLE_SUFFIX
carthage update 2>&1
