This is confusing. I've seen it explicitly said that I can omit
ivars in the "modern" runtime, which explicitly includes the iPhone.
Here it says the iPhone itself does _not_ support the part of the
modern runtime that "accesses Objective-C class metadata," which for
all I know includes synthesis of instance variables.
My take on this is that the simulator is using the OS X 32-bit
runtime, which doesn't support synthesizing instance variables at
runtime. It's another side effect of the simulator environment being a
hybrid between OS X and iPhone.
I don't think "accessing Obj-C class metadata" refers to this feature.
More likely it refers to the APIs that let you introspect classes at
runtime and look up their methods and instance variables.
