Managing asynchronous tasks efficiently is critical to ensure a smooth user experience in our applications. Asynchronous operations, like network requests, file I/O, or heavy computations, can cause an application to become unresponsive and appear to hang if not managed properly. Swift's async and await keywords provide a robust and intuitive way to manage these operations.
Asynchronous functions are marked with the async keyword, indicating that they may pause execution to wait for the completion of another asynchronous task. This allows for operations like network calls to be performed without blocking the main thread, ensuring the user interface remains responsive. The await keyword is used to call these asynchronous functions, indicating that the function's execution may be suspended until the awaited task is complete.
Let’s take a look at how we would use async and await.
