No. You can’t tell anything about a property’s implementation from its return type. You’re assuming it’s a synthesized getter, but there’s no reason it couldn’t be a custom method that does arbitrary computation before returning the value, and there’s no way to know whether that work is thread-safe or not. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
