For meshes whose vertex data is split into multiple vertex buffers (a structure of arrays design), the order of objects in this array reflects the order of buffers in the mesh’s
vertex array, which in turn parallels the order of vertex attributes in the descriptor’s
attributes array. If a mesh contains interleaved data in a single vertex buffer (an array of structures design), the descriptor contains only one
MDLVertex object, which describes the offset between entries for consecutive vertices in the buffer.
