Transport Services Examples

This directory contains practical examples demonstrating how to use the Transport Services API for various networking scenarios.

Examples Overview

Basic Examples

  1. SimpleClient.swift - Basic TCP-like client connection
  2. SimpleServer.swift - Basic TCP-like server listener
  3. UDPExample.swift - Unreliable datagram communication

Advanced Examples

  1. RendezvousExample.swift - Peer-to-peer connection with NAT traversal
  2. ConnectionGroupExample.swift - Managing multiple related connections
  3. MulticastExample.swift - Multicast sender and receiver
  4. ZeroRTTExample.swift - 0-RTT connection establishment
  5. SecurityCallbackExample.swift - Custom certificate validation

Use Case Examples

  1. ChatApplication.swift - Simple chat using reliable messages
  2. FileTransfer.swift - Bulk data transfer with progress
  3. VideoStreaming.swift - Real-time media streaming
  4. GameNetworking.swift - Low-latency game networking

Running the Examples

Each example is a standalone Swift file that can be run with:

swift run ExampleName

Make sure you have built the Transport Services package first:

swift build

Key Concepts Demonstrated

  • Protocol Selection: How Transport Services automatically selects the best protocol
  • Property Configuration: Using pre-configured profiles and custom properties
  • Error Handling: Proper handling of network errors and edge cases
  • Performance Optimization: Using features like 0-RTT and multipath
  • Security: Implementing custom security callbacks and policies
