Overview of this book

Delphi is the most powerful Object Pascal IDE and component library for cross-platform native app development. It enables building natively compiled, blazingly fast apps for all major platforms including Android, iOS, Windows, Mac, and Linux. If you want to build server-side applications, create web services, and have clear GUIs for your project, then this book is for you. The book begins with a basic primer on Delphi helping you get accustomed to the IDE and the Object Pascal language and will then quickly move on to advanced-level concepts. Through this book, we’ll help you understand the architecture of applications and will teach you the important concepts of the FireMonkey library, show you how to build server-side services, and enable you to interact with the Internet of Things. Towards the end, you will learn to integrate your app with various web services and deploy them. By the end of the book, you will be able to build powerful, cross-platform, native apps for iOS and Android with a single code base.

Who this book is for

This book is intended for software developers who know the foundations of programming and can write code in at least one programming language, as it will not teach you the foundations of programming. In other words, if you have never written any line of code in your life, this book is not for you.

This book is meant for developers who might not have used Delphi or for developers who have used Delphi in the past but only for Windows VCL applications, not FireMonkey mobile ones. There is little for Windows and desktop development here, as the focus is on building mobile iOS and Android apps.

This book is packed with practical code examples and best practices for you to become an excellent mobile developer! It is focused on learning by doing – more than just offering many theoretical discussions, it will guide you step by step in rebuilding projects. That is why no expertise in Delphi is required: In most cases, the steps do not assume you have a pre-existing knowledge of the tool or the programming language.

Given the information built on what was presented in previous chapters, though, if you are new to Delphi mobile development, we encourage you to go through the book in sequence: Jumping right away to the final chapters would be a very steep learning curve.
