Comment by Wes Campaigne (JIRA)

Is the code under testing being built with "whole module" compilation mode, or is it using "incremental"?

I was just experiencing a similar issue, and switching the compilation mode setting from "whole module" to "incremental" in the build configuration being used for the tests fixed it.

Are you able to provide a project that reproduces the issue? I suspect if this was indeed being built with whole-module optimization, this may have been fixed by #61158, which stops us from dropping coverage maps if a function gets optimized out.

Please verify with Xcode 14.3 beta 2 and re-open if you are still experiencing this issue.
