You have to know what is a computer and have basic knowledge of how to use a Mac. You have to be curious about how things work. We will start from the basics of the Swift programming language and Xcode. Most of the book is related to iOS, and it would be nice to have an iOS device to see your mobile applications working on a real device.

You need enough time and patience to go through the book and to experiment with the code, which can be found on GitHub.
