If you’re 64-bit only (or if you require Lion or better), there’s no real reason to explicitly declare the ivars these days. As others have pointed out, this is not true. There are practical differences between declaring and not declaring the ivar explicitly. I almost never declare the ivar

Re: About iVars declaration and property

In four words: Fragile Base Class Problem. The problem is that a subclass (in 32 bit OS X) needs to know the size of the superclass so it know how to lay out its ivars.  If there is no explicit ivars, there is no way for the compiler to know the size (since when it is compiling the

Re: About iVars declaration and property

Think of it like the compiler generates the ivars from the property definitions. So the ivar would be indeed explicit ivars - just not defined as such in the classic way. Doesn't matter. The subclass still needs to know the size of its superclass so that it generate the proper ivar offsets.
