My documentation window looks different than the books screenshots–I’ve checked all the view options and preferences but can’t get it to look the same. Here’s what my window looks like: http://imgur.com/cm82k07. Am I missing a download or setting somewhere?
Mine looks like that, too. I think it’s just that Xcode has been updated since the book was written.
All the same features seem to be there, though – e.g. if you click on the ‘More related items’ hyperlink in the class header, there’s a link to Sample Code.
Documentation and API Reference is now available through the Help menu.
In Xcode 5.1 they appear to have updated the navigator. The “i” appears to have been replaced with a link associated with the object.
