// STEP 2: create data & buffer for data source
let vertexData: [Float] = [
0.0,1.0,0.0,
-1.0,-1.0,0.0,

let dataSize = vertexData.count * MemoryLayout.stride(ofValue: vertexData[0]) // use stride instead of size, as this properly reflects memory usage.
let vertexArray = device?.makeBuffer(bytes: vertexData, length: dataSize, options: [])
