This book is aimed at the intermediate iOS developer. After learning the basics of Objective-C and the iOS environment & Xcode, there are many aspects to development that are needed to be a solid developer; this book covers these areas. Topics such as attribute and method naming conventions, documentation, unit testing, sorting & network and application performance are covered in depth (with code examples), so that the developer can improve upon the performance of their app. Written in a easy-to-follow manner, and from a developers perspective, the book covers important topics, giving different options or approaches and the writers explanations for his decisions to use different methods. This book would be a extremely good choice for a developer who has written their first app and is either getting it finalised for submission to the App Store, or for an upgrade of an existing app to a new version.
