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.

Preface

iOS text-to-speech implementation


Each module will retrieve the current container used throughout the entire lifetime of your application. Inside the register function is where we register the class implementation of the text to speech interface. This will be done at the very start of the application before we load anything else.

Let's start first with adding the iOS module. Add a new folder in the iOS project called Modules, create a new file called iOSModule.cs, and paste in the following:

     
    public class IOSModule : IModule 
    { 
        public void Register(ContainerBuilder builer) 
        { 
            builer.RegisterType<TextToSpeech> ().As<ITextToSpeech> ().SingleInstance (); 
        } 
    } 

The next step is to add the iOS text to speech service. Add a new folder called Services and add a new file called TextToSpeech.cs. In this file, we are going to access the iOS AVSpeechSynthesizer:

public class TextToSpeech : ITextToSpeech...
