8 Warnings about metalpetal HOT 5 CLOSED

Xcode does not compile the .metal files for the simulator. You can safely ignore these warnings, since metal code won't run on a simulator.

@YuAo Is it safe to remove .metal files from Build Phases?

@YuAo I tried, not, app won't work in this case.
I found such solution:
https://stackoverflow.com/questions/46254475/ignore-metal-files-when-building-for-ios-simulator-target
But it requires changes in code.
What do you think, about of implementing this solution?
We keep our project free of any warnings and this 8 warnings quite ennoying.

The stackoverflow solution you provided should work.

In the situation of MetalPetal, no code change is required, because MetalPetal loads the metallib file from its own framework bundle. All you need to do is compile the .metal file to a file named "default.metallib" and place it in the MetalPetal.framework bundle.

This solution requires that you change your project / build configurations. And everything about Metal Compiler in your project settings won't work anymore because you are not using Xcode's build system to build .metal files.

I'm not sure it is a good solution for the framework vendor to implement.

I think the proper place for this solution should be the post_install hook of CocoaPods. https://guides.cocoapods.org/syntax/podfile.html#post_install You should be able to write a post install hook to perform the change.

I just removed .metal files from the Compile Sources, and it seems to work well.
