API rejected

Hello everybody

I am making a game with UE4 and I have submmited it to the Apple app store

But I have a problem

My binary gets rejected because:

Your app uses or references the following non-public APIs:

MTLDebugDevice

I have ticked “for distribution” and i have unticked “include debug files”

And I cannot find the API anywhere in my project.

So how can i fix this problem?

Thank you very much for your help
