I try to use MPSImageErode and MPSImageDilate in an app right now with SwiftUI and BigSur, Xcode 12.3
The code

Code Block         let edSize = 9         var erodedilateKernelValues:[Float] = [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0,
                                                 0.0, 0.2, 0.2, 0.2, 0.2, 0.2, 0.2, 0.2, 0.0,
                                                 0.0, 0.2, 0.1, 0.1, 0.1, 0.1, 0.1, 0.2, 0.0,
                                                 0.0, 0.2, 0.1, 0.0, 0.0, 0.0, 0.1, 0.2, 0.0,
                                                 0.0, 0.2, 0.1, 0.0, 0.0, 0.0, 0.1, 0.2, 0.0,
                                                 0.0, 0.2, 0.0, 0.0, 0.0, 0.0, 0.1, 0.2, 0.0,
                                                 0.0, 0.2, 0.1, 0.1, 0.1, 0.1, 0.1, 0.2, 0.0,
                                                 0.0, 0.2, 0.2, 0.2, 0.2, 0.2, 0.2, 0.2, 0.0,
                                                 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]
         let dilateShader = MPSImageDilate(
            device: self.metalDevice!,
            kernelWidth:edSize,
             kernelHeight:edSize,
             values:&erodedilateKernelValues)
         dilateShader.encode(commandBuffer: cmdBuf,
                          sourceTexture: wipTexture!,
                          destinationTexture: erodila)
         let erodeShader = MPSImageErode(
            device: self.metalDevice!,
            kernelWidth:edSize,
            kernelHeight:edSize,
            values:&erodedilateKernelValues)
         
         erodeShader.encode(commandBuffer: cmdBuf,
                          sourceTexture: erodila,
                          destinationTexture: erodila2)
         cmdBuf.commit()
         cmdBuf.waitUntilCompleted()
         wipTexture = erodila2

Resulting in

Code Block 2021-01-02 19:33:40.320954+0900 ***[5330:369599] /AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/MetalPerformanceShaders/MetalPerformanceShaders-124.2.1/MPSCore/Utility/MPSLibrary.mm, line 338: error 'MPSKernel MTLComputePipelineStateCache unable to load function DilateFilter4.

'

when I use the filter with only Zero it actually works

Code Block          var erodedilateKernelValues = [Float].init(repeating: 0.0, count: edSize * edSize)

But I want to try different filter values to see if I can improve the analytics on an image.

Any suggestions ?

Can you file radar with MTLCompilerService crash in CrashLogs when you run the test.

Sorry for late reply; got busy with other stuff. Running on a MBP 2018 with BigSur 11.2.1; GPU Intel UHD Graphics 630 1536 MB
Will try to get the crashlog next time and file radar
