URLProtocol

URLProtocol is a part of the URL Loading System in the Foundation framework. It provides a powerful mechanism for intercepting, inspecting, modifying, and even mocking HTTP requests and responses in your iOS, macOS, watchOS, and tvOS applications. It serves as the backbone for customizing the behavior of URLSession tasks and allows developers to implement custom network protocols, perform custom actions on network requests, and handle custom networking scenarios.

These are the key features and uses of URLProtocol:

  • Custom protocol handling: URLProtocol allows you to implement support for custom URL schemes beyond the standard http, https, file, and so on. This can be useful for handling specific use cases within your app, such as routing internal app requests through a custom scheme.
  • Request and response interception: URLProtocol provides a way to intercept all network requests and responses made by URLSession. This is particularly useful for debugging, logging...
