Downloading Xcode
Xcode is the default integrated-development environment for developing everything related to Mac and iOS. Xcode is available for free and the latest version—at the time of writing this book—is 5.0.2.
The first step is to download Xcode from the Mac App Store. Click on the Mac App Store icon from the dock to open the Mac App Store.
Search Xcode
using the search box and select the appropriate result.
The store page might look something like the following screenshot:
Click on the Install button right under the logo. (If Xcode is already installed, the caption of the button changes to Installed.) The download is around 2.6 GB, so it may take a while depending on the speed of your Internet connection.
It's always a good idea to keep the Xcode installation up to date as updates are frequent.
