Thanks. We have a few PJSIP libs that use the files that have config files with the same file name, yet different paths and Xcode thinks that there are "multiple build commands for the output file" within the derived data + a few dozen "was built for a newer iOS version than being linked".
Ah. Those aren’t Clang warnings (I don’t think.)
I’ve seen the “built for a newer iOS version”. It happens if you build a library with a deployment version of N, then link it into an app with a deployment version of M, where M < N. It makes sense to warn about this, since the library may be depending on OS features that aren’t present in every OS version the app supports. The fix is to either lower the deployment version of the library or raise the one in the app.
