FrenchKit 2016 Conference Talk Proposal - Simplifying your View Controller using Enum
View Simplifying your View Controller using

Enum is probably one of the most powerful feature of Swift. It's simple, yet it allow to easily build complex Finite State Machine. Let's explore how to extract View Controller's state dependant logic into enum and how to test it separatly.

View Controller often take different state depending of some specific state of the App (fetching data, user logged in/off, ...). This can lead to some internal test condition which clutter your code and are also hard to test. Wrapping up this logic into an enum with associated values allow to split this UI logic piece from the rest of the View Controller logic.

View Building your UI Developer's Toolbox with

Building UI can be frustating when it come to tweaking timing, size or others dimensions of your UI component. Let's explore how to build a set of tool that will greatly ease this process in Xcode using Playground.

Timing an animation can be done using CAMediaTimingFunction which can take a prebuild function (Linear, EaseIn, EaseOut, ...) but also modeled after a cubic Bézier curve. It can be tedious to find the right curve shape. Let's build a (almost) drag and drop Playground to tweak any animation using a Bézier curve visual builder.
