Welcome Speech


Zac Sweers, Uber

Code Generating Your Way to Happiness

Zac Sweers
This talk details how the Uber team uses code generation tools to eliminate a class of issues and sources of developer boilerplate. This covers areas primed for this kind of work, recognizing the opportunity to automate this kind of work, and covers some libraries they have built along the way.

Luke Parham, Fyusion

Gotta Go Fast: Building for Speed in iOS

Luke Parham
You will learn how to track every dropped frame in your app and which tools to use in order to make your app work faster.

Ivan Škorić, PSPDFKit

Android Animations Powered by Kotlin and RXJava2

Ivan Škorić
This talk is about effectively chaining Android animations using RxJava2 and Kotlin (for even further simplicity, everything still compatible with Java). When animating UI elements, the Android framework provides listeners for various animation events such as started, cancelled, stopped, etc. What we’ll be doing here is lifting the animation logic into the RxJava chains, thus making the whole process ‘reactive’ with much nicer syntax and better control flow management.
