Migrating to Swift 6 strict concurrency involves adopting strict concurrency rules and modernizing legacy code. This skill provides detailed guidance and decision trees to help you navigate the complexities of adopting strict concurrency safely.

To prevent data races in Swift, you should use actor isolation to protect shared mutable state. This skill explains how actors work and provides best practices for writing safe, performant concurrent code.

You can modernize callback-based networking code by replacing it with async/await patterns to write clear, sequential asynchronous code. This skill offers best practices for writing both sequential and parallel asynchronous code.

Structured concurrency ties task lifetimes to lexical scopes, while unstructured concurrency allows tasks to outlive their creation context. This skill explains these differences to help you manage tasks and threading properly.

Ensuring Sendable conformance requires making your types safe to pass across concurrency boundaries without causing data races. This skill covers Sendable conformance rules and memory management in concurrent Swift applications.

Performance issues in Swift concurrency often arise from improper task management or blocking operations within actors. This skill provides performance best practices and decision trees for managing threading in concurrent applications.
