@lordandrei - I regard this as an error in the original video.

@novistream posted a link to explain why it worked differently on iOS before, and now they’ve fixed it on iOS 11:

@bababoega posted the fix above:

In `viewDidLoad()`, right below `metalView.clearColor = Colors.wenderlichGreen`, add:

```
metalView.depthStencilPixelFormat = .depth32Float

```

Also, in **Renderable.swift** , below `pipelineDescriptor.vertexDescriptor = vertexDescriptor`,  
add

```
pipelineDescriptor.depthAttachmentPixelFormat = .depth32Float

```

Thanks for your help, guys 👋
