iOS is evolving every year to provide a better experience for its users. Not only the system, but also the hardware of iPhone and iPad devices, which require a powerful system like the iOS to utilize the features of hardware is evolving. The latest release of iOS now comes with great features to give iOS developers the chance to develop mobile apps with new ideas or enhance the experience of current apps with new features. The book tries to cover the new features of iOS and let iOS developers get their hands dirty by writing sample demos with the features to understand how they work. The book is not meant to be a theory book, which talks about technical things, such as new APIs, or about any specific topic. The book is a cookbook that takes you within minutes to the point and guides you to build a simple demo to understand what is going on using examples, which is the best way to make things stick in your mind.
