DTFoundation 1.5.0

This update for DTFoundation was originally 1.4.5. But some breakage occurred from fixing the name of a sub spec. So the solution was promote that to 1.5.0. This works because DTCoreText references 1.4.4 which means that it only sees the last version of DTFoundation which still has the typo.

The main theme – besides some minor fixes – was a big clean up effort which aims to reduce the amount of unnecessary classes in the Core and UIKit sub specs, as well as rename the DTHMLParser sub-spec to DTHTMLParser.

Radar: LLVM Enhancement: @switch

Since Apple is starting to enhance LLVM with new language elements I figure that it might be a good time to suggest them as well, of course via Radar.

Especially when dealing with BETA software it is useful to also commit to memory how to take stackshots.

Undefined Symbols

OC asks:

“I’m doing some Objective-C exercises from a Big Nerd Ranch book, and I’m getting these errors. I’m still pretty lost in terms of how to handle unexpected errors and stuff, so I would appreciate the help.”

I’m going into go into much greater depth here answering this question, because of “teaching a man to fish”, ya’know.
