Introduction

Welcome to the exciting world of iOS programming using iOS 6. This latest release of the mobile operating system is packed with some great new features and improvements, and comes with over 200 new features as well as an updated SDK featuring over 1,500 new development APIs that can be incorporated into your applications.

In this chapter, we will look at what integrated development environments (IDEs) and software development kits (SDKs) are needed to develop applications for the iOS platform, Apple's operating system for mobile devices. We will explain the importance of each tool's role in the development cycle, before finally developing our first application. The tools that are required to develop applications for the iOS platform are explained, as follows:

  • An Intel-based Mac computer running the Snow Leopard (10.6.*), Lion (10.7.*), or OS X Mountain Lion (10.8.*) operating system: The essential development tools cannot be installed on any other computer platforms, so if you are running another processor type (such as the older Mac G4 or Mac G5), you're out of luck.

  • iOS 5 SDK (or higher): In order to download the Apple iOS SDK, you must be registered as an Apple developer. The iOS SDK consists of the following components:

    Component

    Description

    Xcode

    This is the main IDE that enables you to develop, edit, and debug native applications for the iOS and Mac platforms using the Objective-C programming language.

    iOS Simulator

    This is a Cocoa-based application that enables you to debug your iOS applications on the computer, without the need of having an iOS device. There are many iOS features that simply won't work within the Simulator, so a device is required if an application uses those features, that is, the Core Location and MapKit frameworks.

    Instruments

    These are the analysis tools that help you optimize your applications and monitor for memory leaks during execution of your application at real time.

    Dashcode

    This enables you to develop web-based iOS applications and dashboard widgets.
