Objective-C Hacker Typer

Objective-C built the iPhone app gold rush, and its square-bracket message syntax is unlike anything else on this site. A screen of it suggests a veteran iOS developer maintaining an app old enough to vote — or at least old enough to predate Swift.

The sample defines a photo-gallery data source with formal @protocol declarations on Foundation and UIKit, in proper pre-Swift style. The nostalgia is fully functional; the code is not.

How to use the Objective-C typer

1. Click the terminal above and mash any keys — each press reveals the next characters of the Objective-C sample.
2. Open Settings to change theme, speed, sounds, Matrix rain, the CRT effect, or turn on Auto-Type so the screen types itself.
3. Use browser fullscreen for a clean movie shot, and Share setup to copy a link that restores everything.

Like every HackerTyping screen, this is harmless entertainment: the Objective-C code is a local, prewritten sample that is displayed and never executed, and your keystrokes are never recorded.
