Using Object Initializers in Swift to replace AllocWithZone

Question

I recently updated my Xcode from Xcode 7 beta 4 to Xcode 7 beta 5 and began to have an error that wasn't present before. That being: "AllocWithZone is unavailable in Swift: use Object Initializers instead."

Here is the code where the error is found:

public func copyWithZone(zone: NSZone) -> AnyObject {
    let copy = self.dynamicType.allocWithZone(zone) as ChartDataSet
    copy.colors = colors
    copy.label = self.label
    return copy
}

What do I substitute in place of ".allocWithZone" so that it utilizes an Object Initializer instead of this Obj C component?

I used this, and the iOS Charts library works for me:

let copy=self.dynamicType.initialize() as! ChartDataEntry

BTW, there's a swift-2.0 branch, updated to beta 5 :-) – daniel.gindi Aug 11 '15 at 17:35
