CodeBreaker

A native Mastermind game for iPhone, built in SwiftUI. It started from a course assignment, and I added more than 20 colour and emoji themes, with zero dependencies.

  • Game rules live in plain Swift model types with no UI inside them; SwiftUI views only render state.
  • Pegs can be colours or emoji across 20+ themes, and the whole board restyles instantly.
  • Started from a course assignment and extended with my own features; a word-based sibling, CodeWordBreaker, checks guesses against a dictionary.
How it works

The story, in chapters.

Chapter 1

A clean model

The game logic lives in plain Swift types (a code, a guess and the match rules) with no UI inside. The views just render state.

Chapter 2

Themes everywhere

Pegs can be colours or emoji, across 20+ themes, and the whole board restyles instantly.

Chapter 3

Play a quick round

The web version below uses the same rules. The real app is native SwiftUI.

Its sibling, CodeWordBreaker, swaps pegs for real English words.
