In what cases is it recommended to use NSOperation for managing asynchronous tasks in iOS development?

NSOperation is recommended to be used when managing complex asynchronous tasks with the ability to:

• Set dependencies between tasks (so that one task executes after another).
• Cancel tasks.
• Control execution priorities.
• Track the execution status of tasks.

This is convenient, for example, when loading data from the network, processing images, or other long-running operations where order and control of execution are important. NSOperationQueue simplifies managing such tasks compared to using GCD directly.
