XCTest Assertion failure in +[XCTRunnerDaemonSession sharedSession]

Hello!

I'm running a pretty straightforward integration test target with swift test --enable-code-coverage, but the test runner seems to crash and exit sporadically during the test cases. It mentions the codecov folder not being found. Is there something I should be looking out for here?

Huh, this might a bug in SwiftPM. Do you mind filing a JIRA with a sample package that reproduces the issue?

I'd love to!

I'll see if I can repro this in a sample package. If not, can this be tracked in a Radar?

Huh... I also see this without the --enable-code-coverage flag:

I think there's a bug with incremental building with code coverage so you might want to try running swift package clean when you change the code coverage flag.
