Attempted to report a test failure to XCTest while no test case was running about nimble

I uploaded a test project with the issue, please take a look.

This is caused by Nimble's CurrentTestCaseTracker.sharedInstance() not getting registered with XCTest. In particular, XCTestObservationCenter+Register.load's override isn't getting called.

Which appears to be caused by Tuist improperly handling Nimble's Package.swift (specifically, it looks like they're not including the NimbleObjectiveC stuff specified in our Package.swift). Until Tuist fixes this, I'd suggest following Tuist's documentation for using the native SPM integration.

I filed an issue with Tuist to hopefully get it resolved at some point.

What's the rest of the error? The message between the "Attempted to report a test failure to XCTest while no test case was running. The failure was:" and "It occurred at: [...]" lines. That'll help with determining what the actual issue is.

Yes, you are right that's how I live now, but it's very difficult compared to the previous behavior.

I haven't looked at @Bogdan-Belogurov's example project, but I just got this unexpected behavior as well. Interestingly, I am also using Tuist.
