Book Description

iOS 9 gives developers new tools for creating apps for iPhone and iPad, and our new edition of the classic iOS guide is updated to match. By writing clean, expressive, and maintainable Swift code, you'll be able to pull in the iOS 9 SDK's enormous feature set to deliver mobile applications. In this completely revised edition, you'll work through an app's entire lifecycle, from creating the project to publishing on the App Store.
