Basetype
MTLDevice_id
Metal MTLDevice type reference
The type id<MTLDevice> is defined in Apple’s Metal framework, but to
remove an unnecessary compile time dependency, an incomplete type definition
of MTLDevice_id is provided in the Vulkan headers:
#ifdef __OBJC__
@protocol MTLDevice;
typedef __unsafe_unretained id<MTLDevice> MTLDevice_id;
#else
typedef void* MTLDevice_id;
#endif
