How do I bridge Combine with async/await with Combine in Swift?

In Swift, you can bridge Combine and async/await using a combination of a custom publisher and Task. This allows you to take advantage of Combine's reactive programming model while still being able to use the async/await syntax for asynchronous programming.


        import Combine

        // A simple Combine publisher
        func fetchData() -> AnyPublisher {
            Just("Hello, Combine!")
                .delay(for: .seconds(2), scheduler: DispatchQueue.main)
                .eraseToAnyPublisher()
        }

        // Bridging Combine with async/await
        func fetchDataAsync() async -> String {
            await withCheckedContinuation { continuation in
                let cancellable = fetchData()
                    .sink(receiveValue: { value in
                        continuation.resume(returning: value)
                    })
                
                // Store the cancellable if needed
                cancellable.cancel() // Cancel after use to prevent memory leaks
            }
        }

        // Example usage in an async function
        Task {
            let result = await fetchDataAsync()
            print(result) // Output: Hello, Combine!
        }
