This workflow is using a deprecated stack. Change your build stack, or your builds will not work after Mar 13

I just saw the message " This workflow is using a deprecated stack. Change your build stack, or your builds will not work after Mar 13"

What does that really mean? I dont know what I have to change.

The machine and stack is

  • Xcode 14.1.x, on macOS 12.5 (Monterey), Gen2 Standard

so it is not that old.

OK, I see the issue now. In the stack view it is written for this stack:

The latest available Xcode 14.1.x installed on macOS 12.0 (Monterey) - Deprecated: will be removed after 2023.03.13
