I'm working on an app to browse a codebase as a list of constructs — classes, methods, etc. It matches how I think about code: as a database of named entities, in which the implementation is often an afterthought — unlike text editors, in which constructs of various types, along with their implementation, all kind of look the same. It's still a very early project, but here's a short recording of some of what I've built so far[^0]. It's been a great way to learn SwiftUI, the Language Server Protocol, and FSEvents as well!
