Swift is a programming language for creating iOS, macOS, watchOS, and tvOS apps. Swift builds on the best of C and Objective-C, without the constraints of C compatibility. Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun. Swift’s clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an opportunity to reimagine how software development works.
This book provides:
- A tour of the language.
- A detailed guide delving into each language feature.
- A formal reference for the language.
It’s a solid book for learning the foundation of Swift Programming Language. I gave it 4-star as few contents are not yet updated to the current Swift specification like declaration of String to be [String]. Otherwise it’s a good read!
