How do I stream responses and handle large payloads in Swift?

Streaming responses and handling large payloads in Swift can be efficiently managed using URLSession's data task with a completion handler and handling data in chunks. Below is an example illustrating how to implement this, ensuring that the application remains responsive during the data transfer.

let url = URL(string: "https://example.com/large-data")!
let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
    if let error = error {
        print("Error: \(error)")
        return
    }
    
    guard let data = data else { return }
    
    // Handle the data in chunks
    let chunkSize = 1024 // Process data in chunks of 1 KB
    var processedData = Data()
    let dataCount = data.count
    
    for index in stride(from: 0, to: dataCount, by: chunkSize) {
        let endIndex = min(index + chunkSize, dataCount)
        let chunk = data[index..
