This book contains a lot of code. We have attempted to make that code and the designs behind it exemplary. We have done our best to follow the idioms of the community, but at times we have wandered from what you might see in Apple’s sample code or code you might find in other books. In particular, you should know up front that we nearly always start a project with the simplest template project: the single view application. When your app works, you will know it is because of your efforts – not because of behavior built into the template.
