I've been fighting the Web interface to Xcode Cloud for a month. I've logged bugs with Apple. Only to have the issue unresolved and punted to someone else... where it seems they file yet another issue on a different ticketing (very opaque to me) and then it seems to go "dark".

Well for a completely different reason - Xcode crashing too many times - I upgraded to 14.1 today. And after launching and reinstalling stuff - it prompted me about Xcode Cloud! What - where/how? So now Xcode has menu options to configure and work with the Cloud Continuous Integration! Yeah! And it worked first try!
And it ran my Unit Test first try! And a few failed - FIRST FRICKING TRY!

The interface is a bit different than running tests locally - but I can work with it. And did I mention... it didn't run on my machine!

Now I will feel the return on investment of writing good tests and renaming the Test function until it is very properly worded... one Test per failure capability. And running in someone else's environment for FREE! This is awesome sauce!
