Getting ready

To run our first Swift program, we need to download and install our IDE. During the beta of Apple's Xcode 9, it is available as a direct download from Apple's developer website at http://developer.apple.com/download, access to this beta will require a free Apple developer account. Once the beta has ended and Xcode 9 is publicly available, it will also be available from the Mac App Store. By obtaining it from the Mac App Store, you will be informed of updates automatically, so this is the preferred route once Xcode 9 is out of beta.
