Lack of real-time test execution and poor test file organization

4/10 Low

Swift testing does not support real-time test execution when files change. Tests must live in separate modules due to Objective-C conventions from 20 years ago, rather than alongside source files, creating organizational friction.

Also in JavaScript land, you can set up your unit tests to run in real-time when you change files. That would be nice to have. Especially if tests could live alongside files, rather than in a separate module because that's how Objective-C decided to do it 20 years ago.
