C++17 Standard library support

Apple clang version 13.0.0 (clang-1300.0.29.3) C++17 still does not support std::boyer_moore_searcher

#include <iomanip>
#include <iostream>
#include <algorithm>
#include <functional>
#include <string_view>
 
int main()
{
    constexpr std::string_view haystack =
        "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed "
        "do eiusmod tempor incididunt ut labore et dolore magna aliqua";
 
    const std::string_view needle {"pisci"};
 
    if (const auto it = std::search(haystack.begin(), haystack.end(),
            std::boyer_moore_searcher(needle.begin(), needle.end()));
        it != haystack.end()
    ) {
        std::cout << "The string " << quoted(needle) << " found at offset "
                  << it - haystack.begin() << '\n';
    } else {
        std::cout << "The string " << std::quoted(needle) << " not found\n";
    }
}
