swap(_:_:)

Declaration

func swap<T>(_ a: inout T, _ b: inout T) where T : ~Copyable

Parameters

• a:

  The first value to swap.

• b:

  The second value to swap.

Discussion

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.
