Compiler error complaining that the type is not a bool. I could cast it, but I bet the compiler would give the same asm output from casting as simply comparing against 0.

static_cast<uint32_t>(deviceExtensions.size() ?

And why have you moved the initialization of enabledExtensionCount and ppEnabledExtensionNames out of the contructor call?

deviceCreateInfo.ppEnabledExtensionNames = deviceExtensions.data();

device = std::make_unique<vk::raii::Device>( *physicalDevice, deviceCreateInfo );
graphicsQueue = std::make_unique<vk::raii::Queue>( *device, graphicsIndex, 0 );
device = vk::raii::Device( physicalDevice, deviceCreateInfo );
graphicsQueue = vk::raii::Queue( device, graphicsIndex, 0 );
}
