Why I’m refactoring to Kotlin

March 21, 2018  5 minute read  

One of the things that is really cool about software development is that we are continually learning and adjusting. I spent a day recently learning Kotlin. I was so impressed with the language, I decided to refactor my entire Family Photos app. It did not take long. Why do I love Kotlin? I have to admit, I was skeptical at first. After all, I tried Swift for iOS as an alternate language and it felt foreign. Admittedly, Objective-C isn’t much better, but Swift definitely had some issues for ...

Testing Mobile Apps: A Primer

March 11, 2018  10 minute read  

Why should you test your mobile app? A recent study showed that almost a quarter of users only use a mobile app once, and a shocking 95% abandon an app within the first month. Some of the reasons that users abandon an app are due to content and engagement. The biggest non-content reasons for abandonment are application crashes and security concerns.

Your First App: Notes or Task List There is a reason that just about every beginner tutorial uses the Todo app or the Notes app as the base. It’s a solid basic app that has a varie...

Creating a React Native bridge library

January 19, 2018  7 minute read  

React Native is really good at straddling the line between native and JavaScript. There is a bridge between the two that allows you to call native code from JavaScript. This is awesome for including things that require a special touch. Most React Native developers will never need to worry about the bridge because libraries exist to wrap a lot of the common native libraries that you see in Android and iOS. But what if you want to create a bridge library of your own? That’s a whole other effor...

AsyncStorage, TypeScript, and Async/await in React Native

August 21, 2017  4 minute read  

In the last few posts, I’ve been working on a Notes app in a master-detail pattern for React Native using TypeScript. This is the last post about that project. So far, I’ve: Worked out how to handle orientation changes. Worked out how to implement swipe-to-delete. Figured out the best way to use TypeScript. Integrated MobX for the Flux pattern. Fixed up the project for universal iOS apps. Finally written the Master-Detail pattern. That’s a lot of stuff. This last post is about...
