Jean Christophe Pastant nous présente son framework opensource Gaikan : Declarative view styling in Swift. Inspired by CSS modules.

1. GAIKAN
STYLING SOLUTION FOR SWIFT
https://github.com/akane/gaikan.git

2. WHY BUILDING A TOOL?
Because making design in iOS is painful

3. INTERFACE BUILDER
No variable :(
A lot of design attributes not configurable

4. BY CODE
A lot of boilerplate code
heterogeneous API
let gradient = CAGradientLayer()
gradient.frame = view.bounds
gradient.colors = [UIColor.blueColor(), UIColor.greenColor()]
view.layer.insertSublayer(gradient, atIndex: 0)
btn.tintColor = UIColor.blueColor()
// VS
navigationBar.barTintColor = UIColor.blueColor()

5. WHAT IS IT?

6. CSS, REACTJS, CSS MODULES
Uniformed API for views (CSS)
Naming (CSS)
No complex selectors (CSS modules, ReactJS)
Explicit dependencies (CSS modules, ReactJS)

7. SIMPLE SYNTAX
import Gaikan
var title: Style = [
.Color: UIColor.whiteColor(),
.Font: UIFont.titleFont()
]
myLabel.styleClass = title

8. EXTENSIBLE
It is just about adding new properties
// As of 0.5.0
public enum Property {
case Background
case Border
case Clip
case Color
case CornerRadius
case Font
case Opacity
case TextAlign
case TextShadow
case TintColor
case Transform
case Visible
}

9. DEMO
Showtime!

10. SUM UP

11. Less boilerplate code
Composable styles
Nice/Uniform API
Not intrusive
style.gradient = Gradient(
(color: UIColor.blueColor(), position: 0.2),
(color: UIColor.greenColor(), position: 0.8))
