The source code used in this chapter is available at https://github.com/PacktPublishing/Delphi-GUI-Programming-with-FireMonkey/tree/master/Chapter%2004/MultiView.
Generally speaking, for the whole book, you need a computer with Delphi set up, a few additional libraries installed (such as Radiant Shapes (https://getitnow.embarcadero.com/?q=radiant+shapes) and CodeSite Logging (https://getitnow.embarcadero.com/?q=codesite)). Having other devices and setting up multiple platforms (iOS, Android, OS X/macOS, and Linux) other than Windows is a plus, but not strictly necessary in order to follow the flow of the book.
