Question

Anonymous · Accepted Answer

Concurrency in iOS works by running heavy tasks in the background so the user
interface stays smooth. It uses three main frameworks:

Swift Concurrency: Modern async/await syntax for clean code.

Actors: Specialized types that prevent data corruption from simultaneous
access.

Grand Central Dispatch (GCD): A system managing FIFO queues and worker threads.

Operation Queues: Object-oriented queues allowing task dependencies and
cancellations.

Main Actor: A tool that forces UI updates to run strictly on the main thread.
