I am very new to coding, so I may not convey my question in the proper terminology...
I am going through Bucky's Objective-C tutorials, and I'm stuck. I understand these tutorials were made years ago, and Xcode and maybe even the language has evolved a little since then.
What exactly is the purpose of '*r' in the line Rectangle *r = [[Rectangle alloc]init] ? When I get an error mark that says "Use of undeclared identifier 'r', how exactly do I correct this?
