Is it necessary to monitor the status of a task in DispatchWorkItem?

Tracking the status of a task in DispatchWorkItem is not always necessary, but in some cases, it is useful. DispatchWorkItem provides a property isCancelled, which allows you to check if the task has been canceled, as well as the method notify(queue:execute:) to receive a notification upon completion.

If you need to manage the lifecycle of a task — for example, cancel it or perform actions after it finishes — it is advisable to track its status. In simple cases, when the task is launched and does not require control, tracking may not be necessary.

Example of usage:

let workItem = DispatchWorkItem {
    // Execute task
}

DispatchQueue.global().async(execute: workItem)

// Later, you can cancel
workItem.cancel()

// Check status
if workItem.isCancelled {
    print("Task was canceled")
}

// Notification upon completion
workItem.notify(queue: .main) {
    print("Task completed")
}
