It appears that Apple is proving a good many samples for Xcode 4 users.
I needed Richard Wentk’s excellent book (entitled simply Cocoa) to find them.
They are interwoven with the Developer documentation. That’s the documentation you can only access when you’re online, remember?
If you’re not accessing it from a browser but from inside Xcode, and browse the Mac OS X Core Library, you find that it contains a lot of examples, which can be downloaded and opened.
(And I am *so not impressed* that half the links have been updated and are getting redirected to the main page so that the samples aren’t easily accessible after all.)
I liked the old way – where you could download documentation and samples in a version that would be guaranteed to run on your computer/version of Xcode – much better. If I hadn’t happened to glance at the right page in the book – and who in their right mind reads up on how to use documentation – I would have missed this feature for some time yet.
So now I’ve downloaded sample code for the things that interest me most – including NSCollectionView – and can start, dodgy internet connection or not, but argh. Life shouldn’t be so difficult!
