Swap would only be used when the kernel runs out of physical RAM or other memory intensive applications require memory and no more physical RAM is available. In which case, kernel swaps out certain processes that are lesser priority or are not running.
By design, kernel uses as much memory as possible to keep anything from going to swap as swap memory is way slower than the physical RAM.
