Ignore .metal files when creating for iOS Simulator target

Question

Whenever I create a project that includes a metal shader in the x86_64 target (iOS simulator), I get a dependency analysis warning:

warning: no rule to process file '[File Path]/Shaders.metal' of type sourcecode.metal for architecture x86_64

I know this is not a huge problem, but I like to leave my projects free of warnings when building, so when a real problem arises, I actually notice a yellow warning triangle.

Any quick way to get Xcode to ignore metal files for simulator purposes?

bash- CompileMetalLib.sh .metal :

xcrun -sdk iphoneos metal -c MyShader.metal -o MyShader.air
xcrun -sdk iphoneos metallib MyShader.air -o MyShader.metallib
rm MyShader.air

-:

let metalLibPath = Bundle.main.path(forResource: "MyShader", ofType: "metallib")
let myLibrary = try metalDevice.makeLibrary(filepath: metalLibPath)

.metal . . , .metal, x86_64.
