Well, the source code shows that it _is_ deprecated:
<https://code.qt.io/cgit/qt/qtbase.git/tree/src/corelib/global/qswap.qdoc>
https://code.qt.io/cgit/qt/qtbase.git/tree/src/corelib/global/qswap.qdoc

I was not able to find a documentation page for qSwap in Qt 6.5,
but here's the link to 6.2: https://doc.qt.io/qt-6.2/qtalgorithms-obsolete.html#qSwap

FTR:

We did _not_ deprecate qSwap(). We banned it from inline Qt code when we
know we can use one of the other ways:

- lhs.swap(rhs);
- std::swap(lhs, rhs);
- qt_ptr_swap(lhs, rhs);

We still use it in generic code, e.g. QList().
