I am using the Xcode beta for developers, and am noticing some subtle differences. Among them is a new attribute for declared properties.

@property(strong)IBOutlet NSArrayController *arrayControl;

My question is: what does the strong attribute mean?? Does it replace some older one, or is it something entirely new? I have searched through google and the developer documentation and havent been able to find anything. Until i know what it is i am hesitant to use it.

Thanks in advance

    It’s a replacement for the retain attribute, as part of Objective-C Automated Reference Counting (ARC). In non-ARC code it’s just a synonym for retain.
