PieChart for ios diagrams broken in Swift 2.0?

Question

So, I updated my project and modules for working with Swift 2.0 and Xcode 7. But now my PieChart no longer works as expected. My pies start from 0 degrees, which means that they all start in the same place one above the other.

Data is added in the same way as before, and if I select it, I see that they are all there, but do not come from their respective places.

Code to add mine pieChartData:

var dataEntries: [ChartDataEntry] = []
var dataPoints: [String] = []

for var i = 0; i < expensesHistory.count; i++ {
    let dataEntry = ChartDataEntry(value: expensesHistory[i].amount, xIndex: i)
    dataEntries.append(dataEntry)
    dataPoints.append(expensesHistory[i].category.rawValue)
}

let pieChartDataSet = PieChartDataSet(yVals: dataEntries)
let pieChartData = PieChartData(xVals: dataPoints, dataSet: pieChartDataSet)
pieChartView.data = pieChartData
var colors = [UIColor]()
colors.append(Colors.blueColor())
pieChartDataSet.colors = colors
pieChartDataSet.drawValuesEnabled = false
pieChartDataSet.sliceSpace = 4.0

The data is loaded and added correctly, in different records (7), but all 7 pies start in the same place ... therefore, they do not lead to a circle at all. Any ideas?
