realm-js: React Native build breaking - 64 bit support

Hi folks,

Our react-native xcode build is failing to archive due to realm. I’ve searched exhaustively, but haven’t found a lead on what could fix this. It looks like it could be due to a 64 bit support requirement? Here’s the error:

Undefined symbols for architecture arm64:
  "realm::util::terminate_internal(std::__1::basic_stringstream<char, std::__1::char_traits<char>, std::__1::allocator<char> >&)", referenced from:
      void realm::util::terminate<unsigned long, unsigned long>(char const*, char const*, long, unsigned long, unsigned long) in libRealm.a(RLMArrayLinkView.o)
      void realm::util::terminate<unsigned long, int>(char const*, char const*, long, unsigned long, int) in libRealm.a(RLMArrayLinkView.o)
      void realm::util::terminate_with_info<int&&gt…

Goals
