When developing for iOS, Xcode is the primary tool. This is a very capable Integrated Development Environment (IDE) that is available for free through the Mac App Store. The free version lets you develop apps and test them on the iOS Simulator. However, if you want to load your software on an actual device, or submit an app to the App Store, you need to have a developer account.
This appendix shows you how to set up Xcode, get a Developer Account, and set up for testing your apps on real devices.
