ARKitFaceExample compiling error

I am getting the same issue.

It does say "// This relies on the earlier check of `ARFaceTrackingConfiguration.isSupported`." Is that the issue ?

I wanted to share my voice that I am experiecing the same issue with this project, including when testing on Xcode 9.1 Beta. While I understand that we will be unable to properly test this project without having iPhone X present, the error leads me to believe that this will not compile on a real device, either. Has anyone been able to successfully run this project at least to a simulator, even though it may crash without a hardware camera?

It runs fine on my iPhone 6s [of course it shows a screen that says the device is not supported, but it still compiles and runs without any problems.]

And yes, it still doesn't run on any of the simulators I've tried, including iPhone X simulator.

I assume this means it will run on iPhone X too when we get our hand on in 4 weeks 😍

I replaced the line:

let device = sceneView.device!

with:

var device: MTLDevice!
device = MTLCreateSystemDefaultDevice()

.. which lets it compile, and run on the iPhone X simulator, but that's still not helpful, as it defaults to the:

"ARKit face tracking requires a device with a TrueDepth front-facing camera .."

I have the same problem, SOMETIMES!

Note:

1. ARSCNView does NOT have a property "device"
   • So it should NEVER compile
   • But it does, SOMETIMES
2. Replacing it with the line:

   let device = MTLCreateSystemDefaultDevice()

   Seems to work consistently

3. I am running on an X

You guys need an iPhone x to deploy it!

The simulator cannot simulate a truedepth camera.

thanks for the code! This worked!

1. var device: MTLDevice!
2. device = MTLCreateSystemDefaultDevice()
