Have you ever used the Combine library in your projects?

Yes, I have used it.

The main application of Combine in my projects is related to handling asynchronous events, such as:

• Network requests: Processing API responses, data transformation, error handling.
• UI element changes: Responding to user actions, text field updates, swipes.
• Local data processing: Tracking changes in databases (e.g., Core Data), notifications from FileManager.
• Creating reactive data streams in MVVM architecture for binding View to ViewModel.

Advantages of using Combine:

1. Reducing code volume and improving readability when working with asynchronous operations.
2. Centralized error handling and operation cancellation.
3. Easy composition and transformation of data streams using operators.
4. Native integration with Apple frameworks (SwiftUI, Core Data, URLSession).

Example of using Combine for a network request:

import Combine
import Foundation

struct APIResult: Decodable {
    let value: String
}

func fetchData(from url: URL) -> AnyPublisher<APIResult, Error> {
    URLSession.shared.dataTaskPublisher(for: url)
        .map(\
