iOS developers: explore the exciting updates and new features in the iOS 8 SDK in this hands-on course by Lee Brimelow. First, familiarize yourself with Swift, the new programming language for iOS, and check out the latest offerings in Xcode 6. Learn how to use playgrounds to quickly preview code in real time, and explore a brand-new way of easily targeting multiple screen sizes: with unified storyboards. See how to broaden the user experience for your apps via app extensions, which let you add functionality such as custom keyboards, photo filters, and more. Then see how to track a user's heath info—including nutrition, fitness, and vitals—with the HealthKit framework, and connect with and control smart accessories for the home with the HomeKit framework. The course also includes tutorials on working with Handoff to sync between iOS and OS X and on using authentication with Touch ID.
