Swift is a programming language for iOS, macOS, watchOS, and tvOS app development. It is designed to seamlessly integrate with Cocoa, Cocoa Touch, and Objective-C, allowing you to use the same familiar classes, patterns, and practices to build apps. Swift makes working with Cocoa and Objective-C safer, faster, easier, and more fun.
This book provides:
– An overview of a Swift Xcode project
– Design patterns and best practices for working with Cocoa, Objective-C, and C
– Step–by–step instructions to use Swift and Objective-C in the same app
