URLSession is the core engine for network requests in iOS. Think of it as your app's private web browser, handling HTTP requests to fetch API data, download images, or upload files. The most common footgun for beginners is blocking the main thread with a network call, which freezes the user interface. Always perform network tasks asynchronously and update the UI back on the main thread.
