Introduction

The ability to persistently store data is a fundamental aspect of app development, enabling developers to create personalized and seamless user experiences. Imagine a scenario where users customize their app settings, such as theme preferences or language choices, and expect those choices to persist even when they close and reopen the app. This is where the importance of data persistence comes into play.

In this lesson, you’ll explore UserDefaults, a valuable tool for reliably storing small amounts of data. Developers commonly use UserDefaults to persist preferences, settings, and other essential pieces of information that enhance the overall user experience. You’ll not only learn how to implement it but also uncover its limitations. By the end of this session, you’ll be well prepared to handle simple data storage tasks using UserDefaults in your SwiftUI projects. Now, it’s time to dive in and discover the power of persistent data!
