One of our students had absolutely no programming experience and was never good at math. Our goal is to make sure that we can create a solid foundation for someone who is starting out. To validate these exercises we worked closely with people who have no programming experience. If you get stuck on a problem, read the solution and try to understand it – if you don’t, feel free to ask for help in a comment! Most exercises have hints that should help you solve them. We estimate that it will take about one month of practice to solve every exercise. They introduce basic programming concepts one by one. This collection of exercises is intended for people with little or no experience with programming. It gives the reader the minimum possible snippets of information to gain the appropriate level of understanding at each point during the book. We decided to make that resource – and more than everything – make it available for everyone.The book was designed using a principle named Cascading Information Theory, which is used in games. We wanted to make an iOS course but we kept on hitting the same wall – there was no resource that will teach people enough programming to be able to make apps.

After Swift was released we knew that a lot of people will want to make apps with it.
