Description

Swift is a general-purpose, multi-paradigm, and compiled programming language developed by Apple Inc. Protocol-oriented programming offers a lot of benefits including better code maintainability, increased developer productivity, and superior application performance. Using right protocols can transform the way you write your Swift code. If you are a Swift developer and want to improve the flexibility, maintainability, and reusability of your code, then you should surely go for this Learning Path.

Packt’s Video Learning Paths are a series of individual video products put together in a logical and stepwise manner such that each video builds on the skills learned in the video before it.

The highlights of this Learning Path are

Use protocols effectively in real-world applications

Solve common problems when working with protocols

Explore some of the new features in Swift 4

Let’s take a quick look at your learning journey. This Learning Path shows you how to get the most out of protocol-oriented programming. With useful examples and practical, step-by-step instructions, you’ll create protocols and use them in your code. Taking you beyond the basics, this Learning Path teaches you advanced techniques and ways-of-thinking that will improve the way you use protocols, and shows you how to solve common problems you’ll face when working with protocols. Finally, you’ll be building your first app with protocols.

By the end of this Learning Path, you’ll be ready to use protocols in production to improve the effectiveness of your code. You’ll be a protocol programming expert!
