Understanding REST requests in Swift

We are now going to explain the process for handling HTTP or HTTPS requests.

Implementing RESTful services in Swift typically involves making HTTP requests to a server, handling the responses, and parsing the JSON data. The most common way to achieve this is by using the URLSession API, which provides the most common native framework for networking in Apple operating systems.

URLSession, which we will examine in full, is part of a larger system, the URL Loading System, provided by Apple’s Foundation framework. The URL loading system is a set of classes designed to access content via URLs. It supports data retrieval, uploading, downloading, and some level of protocol-specific interactions.

The URL Loading System is built around the core concept of communicating with resources identified by URLs, making it suitable for a wide range of network operations, from simple fetch requests to complex network communications.
