Is there a way to accomplish this running tests in Xcode without using a test plan?

Thank you, Frank! I didn't notice those properties before. I'm accepting your answer as the correct one. Though this opinion has no bearing on the correctness of your answer, I think that deprecating the RAW filter's introspective key-value API in favor of a "static", property-based API is a mistake. I see a place for both kinds of APIs, where each complements the other. If you believe there's still a non-deprecated API that would allow developers to read and write RAW filter input keys at runtime, I would love to hear. I hope the deprecated API remains indefinitely supported in the future, even if Apple discourages its use.

FYI I was able to "fix" the problem I was having by doing rm -rf /Users/msa/Library/Developer/Xcode/DerivedData/*

Nope. Still broken! Is this a macOS 12.1 issue???

I just downloaded Xcode 13.1 and I still get the same crash when I try to load my workspace: Swift/NativeDictionary.swift:743: Fatal error: Duplicate values for key: 'https://github.com/Quick/Nimble' Maybe this is a Monterey 12.1 issue? This was working last night. Then I updated to 12.1 overnight. Now it's not working. sigh

No, actually, some of us are still having problems with that version of Xcode, like crashing when building or just starting Xcode.

The Xcode 13.2 from the dev portal was working for me last night. Now when I open my workspace with Xcode it crashes on startup with an error like Swift/arm64e-apple-macos.swiftinterface:13494: Fatal error: Duplicate values for key: 'https://github.com/Quick/Nimble' I've filed a FB request for this, number FB9808715.

Thank you. I will try this.

Yup. Xcode 13.2 downloaded from the releases page crashes on startup with a message like Application Specific Information: Swift/arm64e-apple-macos.swiftinterface:13494: Fatal error: Duplicate values for key: 'https://github.com/Quick/Nimble' ProductBuildVersion: 13C90 Not sure if this is related...

Hmmmmm... that would be an interesting project...

Be sure to file a feedback request on this specific issue.

Maybe they want us to take a break. Stretch, relax, go for a walk. Breathe some fresh air. Maybe take the rest of the day off.
