Tic Tac Toe

In this project, we want to explore the MVC architecture and understand what it means to separate concerns between the Model, View and Controller inside an application.

Our goal is to write a simple Tic Tac Toe game with a dedicated view component (BoardView) that represents the state of the board. The BoardView is implemented as a 3x3 grid according to the rules of Tic Tac Toe. Each cell in the grid is represented by a different view class called FieldView.

At the same time, we have a model object to represent the state of our game. It is implemented as a struct called Board. It keeps track of the current game state by managing a 3x3 matrix of fields. A Field is implemented as an enum that has two cases:

  1. .free: this means the Field is available for a user to make a move
  2. .hasPlayer(player): this case uses an associated value to indicate which player has made a move on this field (note that Player is also implemented as an enum with two cases: .circle and .cross)

Whenever the board receives a touch event from a user, it needs to propagate the info about the event (i.e. the coordinates of the FieldView that has been tapped) to the controller , so that it can advance the game state (i.e. update the model).
