This is a book for complete beginners to Apple’s modern programming language — Swift.
All the code in the book works inside of Xcode’s easy-to-use playgrounds. That means you can focus on core Swift language concepts, such as classes, protocols, and generics, instead of getting bogged down in the details of building apps.
This is a companion book to the SwiftUI Apprentice; the SwiftUI Apprentice focuses on building apps, while Swift Apprentice focuses on the Swift language itself.
