Learning Swift

Learn how to develop a working iOS app from start to finish with this valuable hands-on guide to Swift, Apple's open source programming language. Skilled programmers with little to no knowledge of Apple development can dive right in and begin coding with the latest version of Swift. This practical guide covers Swift programming basics and provides guidelines for making your code "Swifty," as well as working with Xcode and built-in Interface Builder. Step-by-step, you'll build and customize your own app for taking, editing, and deleting selfies, with tips on tuning and testing for performance and managing your app's presence in the App Store. Debug and performance test with Xcode, automate with Fastlane, and user-test with TestFlight. Divided into four parts, this book includes everything you need to know to develop a successful app.
