The explanation that we don't make everything atomic by default is, that there is a overall performance Price and for the majority of things Will not actually need thread basic safety. A few areas of our code have to have it and for people number of sections, we need to produce our code inside of a thread-Secure way making use of locks, mutex or synchronization.

You have to initial erase (dealloc) it and You'll be able to publish onto it. If at the moment the erase is done (or 50 % accomplished) and nothing at all has yet been wrote (or 50 percent wrote) and you also try to read through it could be incredibly problematic! Atomic and nonatomic enable you to address this problem in alternative ways.
