How to Use Protocols. Protocol Composition. Protocol-Oriented Programming | Swift & iOS Basics

Показать описание

After two episodes of examining software interfaces at large, I’m (finally) moving on to Swift protocols in particular. In this video, I’m going over the fundamentals of their use, and demonstrating how to declare protocols, how to conform objects to them, and how to call protocol methods. In addition to that, I’m having a look at protocol composition (protocol inheritance) and explaining the principles of protocol-oriented programming in Swift.
