After turning on iCloud capability, Unit tests no longer run

I started a brand new Cocoa App project today, and included unit tests. Before adding any code, I built the project and ran the boilerplate unit tests. All worked/passed as expected. However, when I then go in and add the iCloud capability (whether I choose just Key-value storage, Cloudkit, or both), the tests no longer run. They don't fail, they just do not run. The project does build and runs just fine. Looking at the error log I see the following:


Test target KeepSafeTests encountered an error (Early unexpected exit, operation never finished bootstrapping - no restart will be attempted)


I haven't added any code mind you, so I'm not sure why simply adding a capability would make the unit tests not be able to run. Any help would be greatly appreciated.
