# vertexDescriptor

A Model I/O vertex descriptor specifying the data layout in the vertex buffers.

## Declaration

```swift
var vertexDescriptor: MDLVertexDescriptor { get }
```

## Discussion

Discussion This is a convenience property. The MTKMesh class does not use this descriptor, but your application may use this object to determine rendering state or create a MTLVertexDescriptor object to build a MTLRenderPipelineState object capable of interpreting the data in vertexBuffers.
