How it works...

To destroy a swapchain, we can prepare code that is similar to the following example:

if( swapchain ) { 
  vkDestroySwapchainKHR( logical_device, swapchain, nullptr ); 
  swapchain = VK_NULL_HANDLE; 
}

First we check whether a swapchain was really created (if its handle is not empty). Next we call the vkDestroySwapchainKHR() function and then we assign a VK_NULL_HANDLE value to the swapchain variable to be sure that we won't try to delete the same object twice.
