20.2.2 Swappable requirements               [swappable.requirements]

3  The context in which swap(t, u) and swap(u, t) are evaluated shall ensure
that a binary non-member function named “swap” is selected via overload
resolution (13.3) on a candidate set that includes:
— the two swap function templates defined in <utility> (20.3) and
— the lookup set produced by argument-dependent lookup (3.4.2).


The usual way to do that is:

  using std::swap;  // overloads in <utility> are candidates
  swap(t, u);       // overloads found by ADL are also candidates
