Overview of this book

Do you want to create powerful, efficient, and independent apps from scratch that will leverage the Xamarin framework and code with C#? Well, look no further; you’ve come to the right place! This is a learn-as-you-build practical guide to building eight full-fledged applications using Xamarin.Forms, Xamarin Android, and Xamarin iOS. Each chapter includes a project, takes you through the process of building applications (such as a gallery Application, a text-to-speech service app, a GPS locator app, and a stock market app), and will show you how to deploy the application’s source code to a Google Cloud Source Repository. Other practical projects include a chat and a media-editing app, as well as other examples fit to adorn any developer’s utility belt. In the course of building applications, this book will teach you how to design and prototype professional-grade applications implementing performance and security considerations.

Now we move on to the user interface design and demonstrate how we set up the link between our presenters. Developing the user interface is no different to developing natively for iOS and Android; the only difference with MVP is that we initialize a view with its related presenter in the constructor.

Let's start by adding a new folder to the Chat.iOS project called Views, add in a new file called LoginViewController.cs, and implement the following:

     {

         private UIActivityIndicatorView _activityIndicatorView;
         #endregion
         #region Constructors
         public LoginViewController...
