Change Label Text Color PieChart

[ghost]

I am trying to change the label text color on a pieChart, with:

self.pieChartView.xAxis.labelTextColor = UIColor.blackColor()

Which results in the error:

public override var xAxis: ChartXAxis
{
fatalError("PieChart has no XAxis")
}

Any help is appreciated.

"PieChart has no XAxis", this is a recent change, check out ChartsDemo as example
