iOS includes Apple's new Grand Central Dispatch framework for managing concurrency. Since Grand Central Dispatch makes heavy use of blocks, Apple's closure-like extension to the C language, this talk will first cover blocks, then go into Grand Central Dispatch. We'll discuss usage and best practices from the ground up for GCD, allowing you to write awesome, performant apps. As an added benefit, since GCD is a system-level framework, everything in this talk applies equally to Mac OS X and iOS!
