Overview

This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. In this course, you will learn how to create an iOS-based multiplayer Tic Tac Toe game using SwiftUI. Throughout the course, you will develop both the game’s user interface and its backend, culminating in an online multiplayer feature. By following step-by-step instructions, you'll gain hands-on experience building the entire app from scratch, including AI functionality and integration with Firebase for online play. The course is structured in sections that will guide you through building each feature progressively. Starting with creating the home view and game modes, you will learn how to design intuitive game interactions with button styles, board designs, and notification features. As you move through the lessons, you will develop the game board, set up the player indicators, handle game moves, and manage notifications for win/loss conditions. You will then progress to creating an AI opponent, which will allow users to play against the CPU, and eventually implement the online multiplayer functionality using Firebase. From setting up the Firebase project to managing real-time game data, you will implement everything required to play against another user. The course finishes with a thorough walkthrough of unit testing and publishing the app to the App Store, ensuring you can bring your app to life and share it with the world. This course is ideal for developers familiar with SwiftUI who want to expand their skills by building interactive, online multiplayer apps. It is also great for developers seeking to learn game logic, Firebase integration, and unit testing within iOS development. By the end of the course, you will be able to build a fully functional multiplayer Tic Tac Toe game for iOS, implement AI logic, integrate Firebase for online multiplayer, test your app with unit tests, and prepare it for publishing on the App Store.

Syllabus

Introduction

In this module, we will introduce the course and what you can expect to build. You will get an overview of the project's goal and the essential tools and frameworks you'll use throughout the course.

Home View

In this module, we will focus on creating the foundational elements of the app’s user interface. You will build the home screen and learn to structure the game modes while customizing the button styles for a unique look.

Game View

In this module, we will dive into building the core gameplay screen. You’ll create the Tic Tac Toe board, design player indicators, and refactor the UI to ensure seamless gameplay. You'll also implement win and draw checks to manage game outcomes.

VS CPU

In this module, we will integrate artificial intelligence to create a single-player experience against the CPU. You’ll learn to generate AI moves and process them to make the game more challenging for users.

Online Game

In this module, we will enable online multiplayer functionality using Firebase. You will learn how to set up the database, sync game states across devices, and manage online players in real time, creating a fully functional online experience.

Unit Tests

In this module, we will focus on ensuring the app works correctly through unit tests. You will write tests for core functions like game move processing and Firebase interactions, helping you catch potential issues early.

Publish to App Store

In this module, we will cover the process of preparing and publishing your app to the App Store. You’ll learn how to configure the necessary settings, submit the app, and understand how to finalize the project before release.
