minor nit: I'd suggest `traits_type` instead of `_Traits` as the parameter here for consistency which the style of the rest of the class definition:
```suggestion
#if defined(_LIBCXX_IOS_USE_FILL_HELPER)
  using _FillType = _FillHelper<traits_type>;
#else
  using _FillType = _SentinelValueFill<traits_type>;
#endif
  mutable _FillType __fill_;
