"Tests failed" with no indication of which tests failed

Hey, not sure if this is an issue with just Swift excersises, but I noticed this issue in both the **Freelancer Rates** and **Vexing Vehicle Purchase** exercises.

Whenever I run the tests and have some syntax/compiler error, it will tell me exactly what I did wrong. However (unlike in the Rust exercises or the **Layers of Lasagna** exercise), I am finding that it will not display which test cases are failing (so I have no idea how to fix them):
