# MasterMind
A small project to dive into the Swift programming language.

## Introduction
Around Christmas 2016, our daughter got the new edition of [Mastermind](http://www.hasbro.com/nl-be/product/mastermind:93765D16-6D40-1014-8BF0-9EFBF894F9D4). Around that same time I was reading [iOS Programming Fundamentals with Swift](http://shop.oreilly.com/product/0636920055211.do). After finishing the first part on Swift, I needed a small project to get my hands dirty and try out some of that new programming language I'd been reading about.
Looking across the table to the game we just gave, resulted in this repository ;-)
The algorithm implemented is a slightly adapted version of the one described by [Donald Knuth](https://en.wikipedia.org/wiki/Mastermind_(board_game)#Five-guess_algorithm). I havent' really focussed on performance, but rather on getting to know language features to implement the code representation and solver in a _clean_ way.
Each code consists of 4 coloured balls, chosen out of 8 possible colours. Feedback on guesses is given in the form of red and white markers, with white indicating a correct colour, but in the wrong location, and red for a correct color in the correct location.
## Running the solver...
Below is a screencast of a session, in which a code is randomly chosen and then solved...
## Running all unit tests
To become familiar with writing unit tests in Swift, I added a few, without being exhaustive, nor thorough.
```bash
$ make test
