Chapter 6. Xcode Tools - Improvements

Since the release of the iPhone 4 back in 2010, developers were impressed by the remarkable 960x640-resolution retina screen display, and provided a way to stay in touch with friends and family, using the FaceTime video-calling feature.

The iPhone 4 camera has been updated and features front and back cameras, as well as a standard 5-megapixel camera with a built-in LED flash and HD video editing that allows you to record and edit stunning HD video. With the release of the iPhone 4S, this has been updated to include the ability to record HD videos at 1080 pixels, with the added ability to directly edit your videos from within the iOS device.
