I downloaded the Xcode 4.2 developer preview version and I created a cocoa application. But I found a very weird syntax in the delegate class:
@property (strong) IBOutlet NSWindow *window;
What does this mean? And the compiler can't even compile it.
Thanks in advance!

The <strong> HTML element indicates that its contents have strong importance, seriousness, or urgency. Browsers typically render the contents in bold type.
A strongly typed programming language is one in which each type of data, such as integers, characters, hexadecimals and packed decimals, is predefined as part of the programming language, and all constants or variables defined for a given program must be described with one of the data types.
b or i means you want the text to be rendered as bold or italics. strong or em means you want the text to be rendered in a way that the user understands as "important". The default is to render strong as bold and em as italics, but some other cultures might use a different mapping.
It indicates that this property is a strong relationship—an ownership. It's ARC's version of the retain keyword in the same context.
And the compiler can't even compile it.
It's valid ARC code, so if your tools support ARC, they certainly should be able to compile it.
Make sure that you're using Xcode 4.2 or later, and that you have the project's compiler choice set to Clang (“Apple LLVM Compiler”).
