Thought I should take a stab at this. Running this fixes the issue:

xcrun simctl spawn booted log config --mode "level:off"  --subsystem com.apple.CoreTelephony

Source: https://stackoverflow.com/questions/52455652/xcode-10-seems-to-break-com-apple-commcenter-coretelephony-xpc

It simply disables logging for the CoreTelephony framework.

Not sure if this needs a PR.

I’d go for this one I think - seems focused?

xcrun simctl spawn booted log config --mode “level:off” --subsystem com.apple.CoreTelephony
