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.

Mind Your Language

The Object Pascal language used in Delphi is constantly evolving. With every new version of Delphi, new features are added to the language. For every mobile and desktop operating system, there is a different Delphi compiler with slightly different functionality, such as automatic reference counting for mobile.

This chapter will cover the following points:

The basic Object Pascal language features
Advanced constructs, such as generics, anonymous methods, class helpers, custom attributes, and Runtime Type Information (RTTI)

The objective of this chapter is gaining fluency in using the Object Pascal language with a focus on mobile Delphi compilers. This chapter is not a definitive reference to every single feature of the programming language of Delphi. The goal is to cover...
