For the most part; but there are some subtleties* that can take some 
extra time to grasp later on as you run into them. (They are 
documented, though, so I recommend giving the docs another read if you 
get confused.)

* For example: how to make a category that's publicly read-only but 
settable inside the class implementation. Atomic vs non-atomic, in 
refcounted vs GC apps. Declaring and implementing properties in 
categories. Properties vs direct ivar access. What is the value of a 
'for...in...' variable after the loop finishes?
