Today, the functionality of the Vulkan SDK gets a major upgrade for Vulkan developers targeting Apple platforms. LunarG is now shipping Device Simulation (DevSim) and Validation layers for the Vulkan SDK on macOS in addition to Linux and Windows. DevSim layers enable Vulkan application development on a highly-capable development system by "simulating" a less-capable target Vulkan implementation through constraining the reported features and resources on the more-capable platform. Validation layers verify that applications are correctly using the reported Vulkan functionality. The validation layers and associated Vulkan loader on macOS also now support Apple Silicon via Universal Binaries.
