If you have never written any line of code, this book is not for you. The chances are that you have been using Delphi already to build applications for Windows. You will not learn about Windows development in this book. We are going to focus on building mobile iOS and Android apps.
There are two main frameworks for visual development in Delphi: VCL and FireMonkey. The VCL, or the Visual Component Library, is designed for building Windows applications. VCL is arguably the best library for building Windows applications. This book is not about the VCL. There are many books and other resources that explain VCL development inside out. While the VCL is for Windows only, with FireMonkey, you can build apps not only for Windows but also for Mac, Linux, Android, and iOS. Mobile app development with the Delphi FireMonkey library is the main focus of this book.
