The Muse codebase is over 5 years old with over 350,000 lines of Swift, and I’m sure is filled with more than a few archeological code-fossils. Like any startup (frankly, like literally every code project), it’s difficult to prune old unused code while keeping up velocity of new features. Code cleanliness is always a tradeoff with velocity, and often comes in second place. That’s why I love tooling that can help automate this otherwise brutally slow manual task.
