Mobile revolution

The Mobile revolution took the market by storm. And now with Swift there is a whole new language to develop iOS apps, but is it really better? And when it comes to apps, what are the best practices for A/B testing? We explored these questions and others in the latest IT Dev Café…

Sidney de Koning - Swift revolution

Swift is more than just a fun playground app on your IPad, it’s a whole new language that changed the way we develop iOS apps. The good thing about Swift is that it doesn’t mean that you’ll have to throw out all your legacy in Objective C. Better yet, you can build on the code that you already have meaning that it is easier to convince your boss to try out this new language.

When one of the attendants mentioned long compiling times during the testing and debugging phase while combining the languages Sidney had a great tip: while compiling the app for testing and debugging you can turn off DWARF and dSIM. You only need to turn these one for your release build. Doing this can decrease your compiling time, so it’s less of a pain in the ass!

Not a Swift developer yet, but ready to explore the possibilities? The Swift Playground app on the IPad is a good way to familiarize yourself with the language or you can just work with textual output via Repl.

Mauricio T Zaquia - A/B testing for mobile

Maurico works for and has more than 200 A/B tests running at the moment. So, who else can tell us more about A/B testing for mobile apps? During his talk, Mauricio covered some best practices. One of the best tips was to keep your variance as small as possible, but not too small. It needs to be small enough to measure wat exactly caused the changed behavior with the user, but not that small that you’d need to offer a new app to the Appstore every day.

A tip for people who want to start with A/B testing and monitor the various tests is using a dashboard. This doesn’t mean that you need to build your own dashboard, you can just use an existing one. Mauricio’s picks are:

  1. Splitforce

  2. Apptimize

  3. Optimizers
