This tutorial will guide you to your first cross-platform application using the Multi-OS Engine installed on Mac OSX* which we refer to as local build. You can also develop your Android* and iOS* applications in Android Studio on Windows* but in order to simulate your iOS application, you will need to remotely deploy your app to a Mac system running Xcode* (hence remote build). For this scenario, check our getting started guide with Multi-OS Engine (remote build). In this tutorial, I will show you how to create a simple Hello World application for Android and iOS with code-sharing between the two applications. In a real-world scenario, most of your application logic will be shared.
