A couple weeks ago I watched a couple of talks on Twitter’s new product Fabric (www.fabric.io). It’s a collection of tools to make mobile developers’ lives easier. According to their documentation, Fabric is more specifically a “set of mobile development tools called ‘Kits’ that help you make your app more stable, add social features like sharing and login, and turn your app into a business with easy monetization.” You can read more about Fabric and the Kits here: https://dev.twitter.com/overview/documentation. This post will focus on one of the functionalities of the Twitter Kit, but let’s just review the other kits before we begin: Crashlytics – Once included in your application, this gives your app analytics, crash reporting, and more. Honestly, this could have come in handy if I had known about the product earlier. Twitter Kit – Gives your app capabilities to more natively access Twitter features such as composing a tweet, and other social integrations. One of the interesting aspects of this Kit is something called Digits. Instead of having your users log in through their Twitter account, they can also log in through SMS without having to worry about a 3rd-party API for infrastructure, or another site having some access to their social history. Mopub – Helps you monetize your app with advertising. I didn’t touch this functionality while playing around with their product. Setting Up Digits from the Twitter Kit I’m going to walk through installing Fabric.io and integrating Digits into my application. One of the first things I noticed is how easy and seamless the whole process was. Probably the best experience I’ve had when dealing with another company’s tool on improving the mobile development experience. 1. Create an account on Fabric.io and download the Fabric App: 2. Create a new Xcode Application This can be in Swift or Obj-C 3. Follow the directions of the plugin in the bar. This was one of the best experiences I’ve personally had when developing a mobile app. It walks you through running a build script for every time the app is built and ran. This works out great, because it lets fabric know if everything is set up properly and it sends you an email if it is (through SendGrid!). A really seamless experience. 4. I followed the instructions for setting up the Digits module of Twitter Kit using their simple app in the menu bar: It let me know what files I needed to modify and how to get started. 5. The end result was creating an app that lets me use SMS for logging users in without having to use a 3rd party SMS provider and worry about those costs. Pretty powerful in my opinion.
