The term "SendMessageSuccessResponse" is not directly applicable to the Apple environment, as it appears to be more relevant to web APIs or messaging systems rather than something specific to Apple's ecosystem. However, Apple developers often need to handle responses from various messaging or network operations, such as sending data over a network or communicating with web services. In the Apple environment, this can be done using various frameworks like URLSession for network operations or CoreBluetooth for Bluetooth communication.

Understanding how to handle success responses in these contexts is crucial for ensuring that your applications can effectively communicate and handle data. This article will guide you through handling successful responses in network operations using URLSession, which is a common task for Apple developers.

Examples:

1. Handling Network Responses with URLSession in Swift

   When performing network operations, you often need to handle the response to ensure that the data was sent successfully and to process any returned data. Here is an example of how to do this using URLSession in Swift:

   import Foundation
   
   // Define the URL and request
   let url = URL(string: "https://api.example.com/sendMessage")!
   var request = URLRequest(url: url)
   request.httpMethod = "POST"
   request.setValue("application/json", forHTTPHeaderField: "Content-Type")
   
   // Create the message data
   let messageData: [String: Any] = ["message": "Hello, World!"]
   let jsonData = try! JSONSerialization.data(withJSONObject: messageData, options: [])
   
   // Create the URLSession task
   let task = URLSession.shared.uploadTask(with: request, from: jsonData) { data, response, error in
      // Check for errors
      if let error = error {
          print("Error: \(error.localizedDescription)")
          return
      }
   
      // Check the response status code
      if let httpResponse = response as? HTTPURLResponse, httpResponse.statusCode == 200 {
          print("Message sent successfully!")
          // Process the response data if needed
          if let data = data {
              let responseString = String(data: data, encoding: .utf8)
              print("Response: \(responseString ?? "No response data")")
          }
      } else {
          print("Failed to send message. Status code: \((response as? HTTPURLResponse)?.statusCode ?? 0)")
      }
   }
   
   // Start the task
   task.resume()

   In this example, we create a POST request to send a message to a web service. We then handle the response to check if the message was sent successfully and print the response data.

2. Handling Bluetooth Responses with CoreBluetooth

   If you're working with Bluetooth devices, you might need to handle responses when sending data to a peripheral device. Here's an example using CoreBluetooth:

   import CoreBluetooth
   
   class BluetoothManager: NSObject, CBCentralManagerDelegate, CBPeripheralDelegate {
      var centralManager: CBCentralManager!
      var peripheral: CBPeripheral!
   
      override init() {
          super.init()
          centralManager = CBCentralManager(delegate: self, queue: nil)
      }
   
      func centralManagerDidUpdateState(_ central: CBCentralManager) {
          if central.state == .poweredOn {
              // Start scanning for peripherals
              centralManager.scanForPeripherals(withServices: nil, options: nil)
          }
      }
   
      func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String: Any], rssi RSSI: NSNumber) {
          // Connect to the discovered peripheral
          self.peripheral = peripheral
          centralManager.stopScan()
          centralManager.connect(peripheral, options: nil)
      }
   
      func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) {
          peripheral.delegate = self
          // Discover services
          peripheral.discoverServices(nil)
      }
   
      func peripheral(_ peripheral: CBPeripheral, didDiscoverServices error: Error?) {
          if let services = peripheral.services {
              for service in services {
                  // Discover characteristics
                  peripheral.discoverCharacteristics(nil, for: service)
              }
          }
      }
   
      func peripheral(_ peripheral: CBPeripheral, didDiscoverCharacteristicsFor service: CBService, error: Error?) {
          if let characteristics = service.characteristics {
              for characteristic in characteristics {
                  // Write data to a characteristic
                  if characteristic.properties.contains(.write) {
                      let messageData = "Hello, Bluetooth!".data(using: .utf8)!
                      peripheral.writeValue(messageData, for: characteristic, type: .withResponse)
                  }
              }
          }
      }
   
      func peripheral(_ peripheral: CBPeripheral, didWriteValueFor characteristic: CBCharacteristic, error: Error?) {
          if let error = error {
              print("Error writing value: \(error.localizedDescription)")
          } else {
              print("Message sent successfully via Bluetooth!")
          }
      }
   }
   
   // Instantiate and start the Bluetooth manager
   let bluetoothManager = BluetoothManager()

   In this example, we use CoreBluetooth to scan for peripherals, connect to a discovered peripheral, and write data to a characteristic. The didWriteValueFor delegate method is used to handle the response after writing data to the peripheral.
