You will spend far more of your coding life reading code than writing it — and an assistant now pulls in dependencies by the dozen. Here a small helper arrives from an open-source package. Read its doc-comment and its code, predict what a call prints, run it — then answer the question the assistant never will: what breaks if a teammate changes one line? Sometimes the doc and the code disagree; the code is what runs.

The code is a teaching subset of the Swift language; the snippets are original teaching examples. Runs on your device — nothing leaves it.
