This week's challenge is Objective-C.

Objective-C was developed in the 1980's as a means to incorporate Smalltalk's messaging system with C-like syntax to develop an Object-Oriented C language, though in a different way than C++. Objective-C is categorized a a strict superset of C. In fact, C syntax will compile on any Objective-C compiler and can be freely used in any Objective-C class. Like Smalltalk, Objective-C also supports dynamic typing. Apple has really taken off with Objective-C, with its Cocoa API for developing applications for the Macintosh OS, iPhone, and iPad.

Getting Started:
There are a number of IDE's for Objective-C including:
-Xcode
-Cocotron
-GNUStep

Resources:
-Apple's Tutorial
-DIC iPhone Tutorials
-DIC Objective-C Tutorials in the C++ Tutorials Section

Finally, it's nice to see Objective C getting some love.
I don't know if there are any other Objective C tutorials on DIC, but mine are here:
Obj-C #1
Obj-C #2

I don't have anything at the moment, but I will most likely be posting something later.

Probably going to have to skip this one as it's still an incredible pain to get any sort of ObjC development going on a windows machine.

is that possible at all, with all those required frameworks?

@Dormilich
Obj-C isn't define by the NeXTStep framework. If you install the Obj-C libraries on a Linux computer you get a very simple base class that is not associated with NSObject.
