    I am in the process of updating the code of my project to be compatible with the new version of ECS. What's the best way to replace the depreciated ForEachComponentGroupFilter ?

    We are using the ArchetypeChunk API in all cases where we used ForEachComponentGroupFilter.

    You could also use ComponentGroup.SetFilter

    I encountered the same issue after upgrading, went back to using SetFilter --but out of curiousity, how do we achieve same result using ArchetypeChunk? I tried looking into that but I couldn't figure out how I could properly replace ForEachComponentGroupFilter.

    With ArchetypeChunk iteration, since you are iterating at the chunk level, and chunks all have the same shared components, you could just check if that chunk has the appropriate shared component up front.
