Bill Hollings has announced the release of MoltenVK Vulkan SDK 1.2.135.

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.

New in Vulkan SDK 1.2.135

• Accurately populate Vulkan VkFormatProperties from MTLPixelFormat capabilities,
  taking into consideration variations across MTLDevice Features Sets.
• Validate format capabilities for MSAA, renderpass attachments, and vkCmdResolveImage().
• Fix issue where immutable samplers are removed during descriptor update.
• Guard against Metal validation assertion from reuse of query number within a single MTLRenderEncoder.
• Increase value of VkPhysicalDeviceLimits::minStorageBufferOffsetAlignment
  to 16 to avoid Metal validation assertions.
• Add ability to disable command memory pooling using MVK_CONFIG_USE_COMMAND_POOLING
  environment variable.
• Fix memory leak when pre-filling MTLCommandBuffers using MVK_CONFIG_PREFILL_METAL_COMMAND_BUFFERS.
• Fix issue causing screen captures from swapchain image to deadlock.
• Fix memory estimates for iOS 13+.
• Broaden conditions for host read sync for image memory barriers on macOS.
• Fix issue of reseting CAMetalDrawable and MTLTexture of peer swapchain images.
• Fix the make install build command to overwrite the existing framework in the system
  framework library, and update README.md to clarify the instructions for using make install.
• Update the README.md and MoltenVK_Runtime_UserGuide.md documents to clarify that
  MoltenVK is not a fully-compliant implementation of Vulkan.
• Support Xcode 11.4.
• Disable API-Samples demos and document in Demos/README.md.
• Update dependency libraries to match Vulkan SDK 1.2.135.
• Update to latest SPIRV-Cross version:
  • MSL: Support inline uniform blocks in argument buffers.
  • MSL: Move inline uniform blocks to the end of the argument buffer.
  • MSL: Fix access chain for deep struct hierarchy on array of buffers.
  • MSL: Remove old memory_scope flag from iOS barriers.
  • MSL: Fixes to array handling.
