How can a single queue process multiple tasks or operations simultaneously?

In iOS, a Concurrent Dispatch Queue from GCD (Grand Central Dispatch) is often used to handle multiple tasks simultaneously. This queue allows running several operations in parallel, distributing their execution across different threads, which increases performance.

Example: if you have several independent tasks, you can add them to a concurrent queue, and they will be executed simultaneously rather than sequentially.

let concurrentQueue = DispatchQueue(label: "com.example.concurrentQueue", attributes: .concurrent)

concurrentQueue.async {
    print("Task 1")
}
concurrentQueue.async {
    print("Task 2")
}

Thus, one queue can handle multiple tasks at the same time through parallel execution on different threads.
