The point being made in those videos was that Foundation networking does not integrate well with Grand Central Dispatch right now, so if you want to do Foundation-based networking a runloop is your best bet for avoiding the problems of traditional threads. However, in Session 206 – “Introducing Blocks and Grand Central Dispatch on iPhone”, you’ll see that they show an example of how to use GCD for just this purpose.
Me, I prefer GCD because of the elegance of the code and because (as they state in those videos) it is the way of the future.
