Learn how to build a powerful social messaging app that leverages a range of AWS services. In this demo-heavy workshop, we show how you can build an app using Apple Swift and the AWS Mobile Hub. This is a step-by-step journey where you configure and add components to your architecture, then modify and test your components. In the end, you will have a mobile app with a backend running on AWS.
