Swift is Apple country: protocol-oriented design, clean type inference, and framework names that start with capital letters. If your fictional hacker owns exactly one laptop and it is aluminum, their screen is Swift.
The sample builds blockchain primitives on Foundation and CryptoKit — protocols for blocks, hashing, and big-integer math. Cryptographic-looking, entirely decorative, never run.
Like every HackerTyping screen, this is harmless entertainment: the Swift code is a local, prewritten sample that is displayed and never executed, and your keystrokes are never recorded. See the main hacker typer, the filmmaker guide for shooting tips, or the privacy policy. A project of Wild Monkey Labs.
