MoltenVK is a Vulkan Portability implementation. It layers a subset of the high-performance, industry-standard Vulkan graphics and compute API over Apple's Metal graphics framework, enabling Vulkan applications to run on macOS, iOS and tvOS.
This is in support of a Khronos contract to reduce CTS failures in MoltenVK, leading up to certification as a Vulkan Portability implementation.
These failures are caused by the lack of support for nested arrays and structures as input to a tessellation evaluation shader. The easiest way to fix this is to simply use raw buffer input instead of vertex-style input. Then we get the support "for free" with no clumsy workarounds required in SPIRV-Cross.

66 CTS failures will be fixed by this change.
