func swap<T>(_: inout T, _: inout T)

Exchanges the values of the two arguments.

The two arguments must not alias each other. To swap two elements of a mutable collection, use the swapAt(_:_:) method of that collection instead of this function.

Parameters: a: The first value to swap. b: The second value to swap.
