In Chapter 15, I’ll introduce you to Grand Central Dispatch and also show you how to use the iOS features that allow you, under certain circumstances, to run your application in the background. • Everyone loves to draw, so we’ll look at doing some custom drawing in Chapter 16, where we’ll introduce you to the Core Graphics system. • In iOS 7, Apple has introduced a new framework called Sprite Kit for creating 2D games. It includes a physics engine and animation systems, and works for making macOS games, too.

However, when writing software, the size that really matters is the one in the Software Size column. As you can see, in most cases, the software size reflects only half that of the actual hardware. This situation came about when Apple introduced the first Retina device, which had twice as many pixels in each direction as its predecessor. If Apple had done nothing special, all existing applications would have been drawn at half-scale on the new Retina screen, which would have made them unusable.

Xcode is also tightly integrated with LLVM, which gives it some new superpowers. Xcode can offer more precise code completion and it can make educated guesses as to the actual intent of a piece of code when it produces a warning and offers a pop-up menu of likely fixes. This makes errors like misspelled symbol names and mismatched parentheses a breeze to find and fix. LLVM brings to the table a sophisticated static analyzer that can scan your code for a wide variety of potential problems, including problems with memory management.
