Objective-C is @synthesize required or optional?
Unless you've been using it like I have, then you still need it, as far as I can tell:
@property int32_t FwdID;
usage inside class:
FwdID = 0;
From what I can tell, if you want the default to work for you, you'll have to type _FwdID = 0; in the code, which just looks ugly to me.
So if you are like me (breaking all the standard coding conventions I assume), you'll still need to use synthesize.
