In the article, Maxim Egorov, an iOS developer, explains the utility of the Network.framework for managing lower-level networking tasks, particularly with the UDP protocol. He highlights the importance of direct control over transport layer communication provided by this framework, emphasizing its benefits for real-time applications where low latency is crucial, such as VoIP calls and online gaming. Unlike TCP, which requires connection establishment and introduces latency, UDP offers a connectionless communication method ideal for scenarios where speed and minimal overhead are prioritized, while also facilitating the development of IoT devices and custom protocols.
In contrast, UDP is a connectionless protocol, meaning data can be sent immediately without establishing a session beforehand. This makes it ideal for real-time applications where speed is critical, where minor packet loss is acceptable but low latency is essential.
At the application layer, iOS developers commonly use URLSession for HTTP-based communication. For lower-level networking tasks, such as working with TCP and UDP, the Network framework provides more direct control over transport layer communication.
