You've got a great idea for an Apple Watch app. But how do you get your app from idea to wrist? This book shows you how to make native watchOS apps for Apple's most personal device yet. You'll learn how to display beautiful interfaces to the user, how to use the watch's heart rate monitor and other hardware features, and the best way to keep everything in sync across your users' devices. New in this edition is coverage of native apps for watchOS 2. With the new version of the WatchKit SDK in Xcode 7, your apps run directly on the watch. On Apple Watch, your app is right on your users' wrists, making your code closer than ever before. Create native watchOS apps by extending your iPhone app with a WatchKit Extension, giving your users quick access to your app's most important features and an intimate user experience that's always within arm's reach. You won't just be creating apps - with Glances to provide timely information, notifications to inform your users of the latest updates, and watch face complications to show your users data as soon as they raise their wrists, your watchOS apps will be the best the App Store has to offer. Any book can teach you how to make a watch app. This book will help focus your efforts and refine your app's feature set. Which features make sense on the watch? How should you organize them? You'll learn what to consider when judging watch app features, allowing you to come up with the best strategy for your app. You'll test your apps on real Apple Watch hardware, and by the end of this book, you'll be ready to ship to the App Store. What You Need: You'll need a Mac running OS X Yosemite capable of running Xcode 7 or later. To build your apps for your Apple Watch, you'll need to be running watchOS 2 or later, connected to a compatible iPhone.

Allan Kaprow

"Childsplay is an extraordinary book. Jeff Kelley not only narrates the history of Allan Kaprow's art but also tells the story of art in the last half of the twentieth century from an entirely fresh point of view. He makes sense of performance history in the context of developments in the more traditional art media in a way that I find consistently illuminating."—Henry Sayre, author of The Object of Performance: The American Avant-Garde Since 1970 "Allan Kaprow's Happenings? You had to be there, goes the retort. But the next best thing, it turns out, is reading David Antin's witty first-hand accounts and Jeff Kelley's illuminating discussion of this singular form of vanguard performance art."—Christopher Knight, art critic, Los Angeles Times "Allan Kaprow is one of those rare artists whose ideas and innovations have changed the practice and theory of art in his own lifetime. As a founding father and a leading practitioner of performance and conceptual art, he created works that have run the risk of ephemerality, leaving few traces or objects behind them. It is the achievement of Jeff Kelley's Childsplay that Kaprow's seminal works (or "play" as the title would have it) are now brought sharply and vividly back to the present. The result is not only historically and critically alive, it is nothing short of monumental."—Jerome Rothenberg, poet, professor emeritus of visual arts and literature, University of California, San Diego "Happenings were wild, exciting, stimulating, and engaging. And best of all, the everyday person could participate. Allan Kaprow has had an enormous impact on art and performance. Now with Childsplay you will have the wonderful opportunity to revisit his work and enjoy his creativity and stunning imagination. Perhaps you will be inspired to reinvent one of Kaprow's Happenings or better yet, create one of your own."—Anna Halprin "A Happening is an important moment in twentieth-century art. To understand a Happening you must start where Happenings began, with Allan Kaprow."—Dennis Hopper
