Well that’s that. The Xcode 4 book is finished and currently being printed (and prepared for digital sale in a number of formats as well). You can preorder it now if you like. See the official announcement for (un)specific dates.
Special thanks to the crew at Peachpit (Cliff, Myrna, Scout, Robyn, Kim, and the design team I didn’t get a chance to work with directly). Thanks to all my friends and colleagues for their support and to Matt for putting up with the whole thing. Thanks to Cyril and Colin for allowing me to use their work while writing the book. Finally, thanks to Duncan for getting me in touch with Cliff.
