This worked for me.
You should be able to work around it by turning off Metal Validation in Scheme -> Edit Scheme -> Run -> Diagnostics -> Metal API Validation

I have an iOS application which uses VNDetectFaceLandmarksRequest to find faces from the camera feed. This is a project I began in 2017 and recently began working on again. I am running the request within an asynchronous DispatchQueue but I am getting the following error:
Execution of the command buffer was aborted due to an error during execution. Caused GPU Timeout Error (IOAF code 2)
Execution of the command buffer was aborted due to an error during execution. Ignored (for causing prior/excessive GPU errors) (IOAF code 4)
How can I debug this?
I get this error in case I use texture that is not properly initialised. Add some basic setup and create texture in swift for Metal like this:
let texDescriptor = MTLTextureDescriptor.texture2DDescriptor(pixelFormat: MTLPixelFormat.rgba8Unorm, width: 128, height: 128, mipmapped: false)
textureImage = device.makeTexture(descriptor: texDescriptor)
I'm recieving an error when enabling Depth of Field with iOS12. Didn't have this error with iOS11.
validateComputeFunctionArguments:843: failed assertion `Compute Function(downsample_4x_dof): missing buffer binding at index 1 for outbuf[0].'
The error that ComputeFunction must not be nill was reported after a metal shading function has been called repeatedly for about 248 times.
/Library/Caches/com.apple.xbs/Sources/Metal/Metal-56.6/Framework/MTLComputePipeline.mm:230: failed assertion `computeFunction must not be nil.'
Abort trap: 6
The first 247 calls worked correctly, but the program failed at the 248th call.
What causes this and how can it be avoided?
Thanks in advance.
only the command buffer and encoder are transient and can be created on every call (inside the draw() function). libraries/functions are not transient so you should avoid creating them repeatedly.
When trying the example on http://msdn.microsoft.com/en-us/library/dd904198(v=XNAGameStudio.40).aspx the program crashes on
Line 69: "player.Play(video);"
error message: "An unhandled exception of type 'System.InvalidOperationException' occurred in Microsoft.Xna.Framework.dll
Additional information: An unexpected error has occurred."
I did not change a single character in the code, but used exactly the files as they came out of the VideoPlayback_4_0.zip folder. (can be directly downloaded from http://msdn.microsoft.com/en-us/library/dd904198(v=XNAGameStudio.40).aspx)
I have read in other forums from people experiencing the same problem, but I could not find a usable solution. Does anybody know what causes the problem and how to fix it?

The codex were the problem. Reinstalling Windows resolved the issue.
