Bill Hollings has announced the release of MoltenVK Vulkan SDK 1.2.148.

MoltenVK is a driver-level implementation of the Vulkan 1.0 graphics and compute API, that runs on Apple's Metal graphics and compute framework on both iOS and macOS.

MoltenVK allows you to use the Vulkan graphics and compute API to develop modern, cross-platform, high-performance graphical games and applications, and to run them across many platforms, including both iOS and macOS.

• Add support for tvOS platform.
• Add support for iOS Simulator and tvOS Simulator build destinations.
• Cube demo runs on tvOS, iOS Simulator, and tvOS Simulator.
• MoltenVK Xcode schemes support building fat Platform+Simulator binaries.
• Makefile supports building fat Platform+Simulator binaries, plus Debug builds.
• fetchDependencies script supports platform build selection, plus parallel builds.
• vkCmdBlitImage() returns error if scaling or inverting to linear image on macOS.
• Support VK_FORMAT_A2B10G10R10_UNORM_PACK32 as a surface format.

• Update VK_MVK_MOLTENVK_SPEC_VERSION to 27.
• Update dependency libraries to match Vulkan SDK 1.2.148.
• Update to latest SPIRV-Cross version:
  • MSL: Add support for processing more than one patch per workgroup.
  • MSL: Workaround broken scalar access chain behavior in MSL LLVM IR / AIR.
  • MSL: Do not emit swizzled writes in packing fixups.
