Class variables not yet supported

Question

I begin my project with a split view controller as initial view controller and start it automatically from storyboard. Generally, an app with this UI have one and only one split view controller as root, so I create a static variable in the subclass and set it when initialisation was done. So I want try this behaviour with swift. I read the Swift programming language guide book on iBook about Type properties (with static and class keyword) and trying a piece of code to the job: ``` import UIKit class SplitViewController: UISplitViewController { class func sharedInstance() -> SplitViewController { return SplitViewController.instance } class let instance: SplitViewController = nil init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) { super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil) self.initialization() } init(coder aDecoder: NSCoder!) { super.init(coder: aDecoder); self.initialization() } func initialization() { SplitViewController.instance = self; } } ``` but…

Accepted Answer

Swift now has support for static variables in classes. This is not exactly the same as a class variable (because they aren't inherited by subclasses), but it gets you pretty close:

```
class X {
  static let y: Int = 4
  static var x: Int = 4
}

println(X.x)
println(X.y)

X.x = 5

println(X.x)
```
