OBJECTIVE-C FOR SWIFT DEVELOPERS

LEARN APPLE'S ORIGINAL LANGUAGE

Swift is a powerful, modern programming language that will continue to grow over the years ahead. But with over a million existing apps written in Objective-C, you almost certainly need to be able to read, write, and maintain both Swift and Objective-C if you want to score a great job making iOS apps.


Build on Swift

This course transfers your Swift skills to Objective-C, and assumes you already know how to make iOS apps – zero time is wasted explaining Swift techniques

Comprehensive

You'll learn the complete language, including pointers, blocks, protocols, categories, and Objective-C++ – you'll be equipped to tackle any codebase.

Hands-on

The course includes three projects to help you apply what you learned, plus a video where I walk you through converting a complete Swift project.

New and old

All Objective-C syntax is covered, from old things like ivars to new things like nullability, giving you the skills to work with whatever the world throws at you.

WHAT'S IN THE COURSE


Objective-C for Swift Developers is an accelerated course designed to teach you Objective-C by drawing parallels with your existing Swift knowledge. It includes three complete projects for you to complete, along with example solutions, plus a hands-on video where I walk you through converting a Swift project to Objective-C so you can see exactly how it all works.
