@GitHubyangjunyi have you found solution?

Have you tried adding the path of MTIShaderLib.h file to the Metal Compiler - Header Search Paths (MTL_HEADER_SEARCH_PATHS) setting?

CocoaPods

• set the MTL_HEADER_SEARCH_PATHS to ${PODS_CONFIGURATION_BUILD_DIR}/MetalPetal/MetalPetal.framework/Headers or ${PODS_ROOT}/MetalPetal/Frameworks/MetalPetal/Shaders.

Swift Package Manager

• set the MTL_HEADER_SEARCH_PATHS to $(HEADER_SEARCH_PATHS)

@bojanstef It’s only possible in the project. But here we are trying to use MetalPetal in SPM package as you can see on screenshot

From searching around it seems it's not possible at all in the SPM package, a potential hacky workaround is something like this:
