Learn Grand Central Dispatch (GCD) in Swift by understanding how to manage concurrent programming and improve app performance in iOS applications. This training covers how GCD handles task execution using queues, threads, and asynchronous processing. It also explains the difference between serial and concurrent queues and how to use them effectively. You will learn how to perform background tasks such as network calls, file processing, and UI updates without blocking the main thread. The course also covers dispatch queues, quality of service (QoS), and best practices for writing efficient, responsive applications. It focuses on building smooth, high-performance iOS apps by properly managing concurrency.
