To implement safe async/await concurrency in Swift, you should use actors for thread safety and structured concurrency patterns. This approach isolates state and prevents race conditions without relying on legacy callbacks.

The best way to refactor into protocol-oriented architecture is to replace heavy class hierarchies with protocols and value types. This reduces technical debt and simplifies SwiftUI state management.

ARC memory management automatically tracks reference counts to free unused objects in iOS apps. Optimizing it requires minimizing retain cycles and profiling memory to ensure high-performance code execution.

Yes, you can use SwiftUI state management templates across macOS, watchOS, and tvOS apps. The skill provides standardized patterns that ensure consistent state handling across all Apple platforms.

You need XCTest implementation to validate that your code adheres to Swift API design guidelines. It ensures high-performance behavior and prevents regressions when building complex applications.

You should use actor-based thread safety when you need structured concurrency and simplified state isolation in Swift 5.9+. Actors prevent data races more cleanly than traditional dispatch queues.
