Not working

[miquellaboria]

When I execute, I get an error:

Error Domain=MTLLibraryErrorDomain Code=5 "Function mtiSurfaceBlur was not found in the library" UserInfo={NSLocalizedDescription=Function mtiSurfaceBlur was not found in the library}

My code is:
`
guard let cgImage = image.cgImage else { return }

    let filter = MTISurfaceBlurFilter(radius: radius)
    filter.threshold = threshold
    filter.inputImage = MTIImage(__cgImage: cgImage, options: nil, isOpaque: true)

    let options = MTIContextOptions()

    guard let device = MTLCreateSystemDefaultDevice(), let context = try? MTIContext(device: device, options: options), let outputImage = filter.outputImage else {
        return
    }

    do {
        let filteredImage = try context.makeCGImage(from: outputImage)

        filteredImg = UIImage(cgImage: filteredImage)
        importImage.image = filteredImg
    } catch {
        print(error)
    }`

Any help is appreciated! Thanks!

Try change the function name here to "metalpetal::surfaceblur::mtiSurfaceBlur"

SurfaceBlur/SurfaceBlur/MTISurfaceBlurFilter.m

Line 40 in 22d8726

fragmentFunctionDescriptor:[[MTIFunctionDescriptor alloc] initWithName:@"mtiSurfaceBlur" constantValues:constants libraryURL:MTIDefaultLibraryURLForBundle([NSBundle bundleForClass:self.class])]
