How do I create publishers and subscribers with Combine in Swift?

The Combine framework in Swift allows you to work with asynchronous events through publishers and subscribers. This powerful framework provides a declarative Swift API for processing values over time. Below is an example demonstrating how to create a simple publisher and subscriber using Combine.


        import Combine

        // Define a publisher
        let publisher = Just("Hello, Combine!")

        // Create a subscriber
        let subscriber = publisher.sink { value in
            print(value)
        }
