Asynchronous Programming with Async/Await in Swift

Harness the power of Swift's async/await for smooth and efficient asynchronous programming, complete with error handling.

// Perform asynchronous tasks using async/await
func fetchData() async throws -> String {
    // Simulate fetching data asynchronously
    await Task.sleep(2_000_000_000) // Sleep for 2 seconds
    return "Data fetched successfully"
}

async {
    do {
        let result = try await fetchData()
        print(result)
    } catch {
        print("An error occurred: \(error)")
    }
}()
