PairForge

Real coders read code in pairs — one screen, two sets of eyes. One of you is the 🧭 Navigator: read the program out loud and predict what it prints. The other is the 🚗 Driver: check it — agree, or say you read it differently, then talk it over and agree on one. Then reveal the real trace. The Driver catches the misread the Navigator would ship — that is the whole point of pairing. You cannot reveal a read you have not predicted. Swap roles each round and count your turns together.

Grab a partner. These programs are written in a teaching subset of the Swift language.
