I read the beta 8 version of this book. I can’t say it felt incomplete or inaccurate. As I’m writing this newer version has hit my inbox.
Xcode Treasures should be on the must-read list of any developer who’s starting with Apple platforms. Not to say it is not useful for experienced ones. Curious how manual code signing actually works? Do you look down on Storyboards? Whant to know little time savers that are all over Xcode? Finally, do you want an excellent guide to an xcodebuild tool you're fighting on CI machine every week? Read this book. I wish Chris wrote this book at least five years ago.
