Not disagreeing with anything that you're saying, except that dictionaries are declared `[Key: Value]` and not `[Key, Value]`. By the way, rather than using `.

Not disagreeing with anything that you're saying, except that dictionaries are declared `[Key: Value]` and not `[Key, Value]`. By the way, rather than using `.filter { ... }.first`, you should really use `.first(where: { ... })` instead. `filter` will iterate the entire sequence, while `first(where:)` stops after it finds a match.
