`_LIBCPP_ENABLE_ASSERTIONS` was used to enable the "safe" mode in libc++. Libc++ now provides the hardened mode and the debug mode that replace the safe mode. For backward compatibility, enabling `_LIBCPP_ENABLE_ASSERTIONS` now enables the hardened mode. Note that the hardened mode provides a narrower set of checks than the previous "safe" mode (only security-critical checks that are performant enough to be used in production).
