 Swift's **Structured Concurrency** is designed to address data races in concurrency for functions and closures. However, working concurrently usually involve dealing with **shared mutable state**, requiring tedious manual synchronization. 
 
-To address this, Swift introduces **Actors**, a new **reference type** designed to encapsulate state within a specific concurrency domain, ensuring **data isolation** and **thread-safe** operations. Actors not only enhances safety and efficiency but also aligns with Swift's established patterns and features.
