Implementing the game logic for our SlidingTiles Game

In this section, we will start by creating and implementing the logic needed to complete our SlidingTiles game. We will start by creating and implementing a GameTile Interface and Class, which will be used to create and store each of our GameTiles.

We will then move on to implementing the required code, as well as the necessary instance method implementations that will make up and complete our game.

Creating and implementing the GameTile Interface class

As explained in the introduction to this section, we will start by creating the GameTile interface class for our SlidingTiles game, which will be used to create instances of each game tile that will be displayed in the gameboard View control we added to our ViewController contained in our Storyboard.

Let's start by creating the IGameTile interface for our SlidingTiles app by performing the following steps:

1. Ensure that the SlidingTiles solution is open in the Visual Studio for Mac IDE.
2. Next,...
