Introduction

In today’s apps, concurrent programming is vital for delivering responsive and efficient user experiences. However, managing shared mutable state safely can be challenging in a concurrent environment.

This lesson focuses on Swift’s actor keyword. This simplifies concurrency by serializing access to shared data. You’ll also learn about the differences between actors, structs, and classes, and how to identify scenarios where actors can be used to prevent things like race conditions.

What You’ll Learn

By the end of this lesson, you’ll be able to:

• Explain the differences between actors, structs and classes.
• Explain the purpose of actors and their role in Swift’s concurrency model.
• Highlight how actors ensure thread safety by serializing access to their state.
