Have you had experience using OperationQueue in your projects?

Yes, in iOS projects I have used OperationQueue to manage asynchronous tasks. OperationQueue allows creating and managing queues of operations (Operation), which can be executed concurrently or sequentially, making it convenient for organizing multithreading.

For example, you can create several operations for downloading data from the network and add them to the queue, while the system manages the number of tasks running simultaneously:

let queue = OperationQueue()

let operation1 = BlockOperation {
    // Download data from network
}

let operation2 = BlockOperation {
    // Process downloaded data
}

operation2.addDependency(operation1) // operation2 will execute after operation1

queue.addOperations([operation1, operation2], waitUntilFinished: false)

This helps avoid blocking the main thread and simplifies dependency management between tasks.
