Cocoa and Swift make a great team for building Mac desktop apps. Cocoa is the framework in which macOS is written, and Swift is the language that makes working with Cocoa classes and APIs easier than ever before. Their compatibility makes Swift a convenient and powerful tool to integrate into your Cocoa app development workflow. Here Todd Perkins walks you through the steps to creating macOS applications with this powerhouse combo. He'll take you through the basic concepts behind Cocoa, Swift 3, and the development environment known as Xcode, and some important concepts, such as the Model-View-Controller design pattern, interaction, and delegation. Then you'll go straight into development. Learn how to create user interface elements and connect them to code, work with Cocoa bindings and key-value coding, and debug your applications and submit them to the Apple Store for distribution.
