private func setChart(pieChartView: PieChartView, values: [Double]) {

    var dataEntries: [ChartDataEntry] = []

    let dataPoints = ["Apr","May","July"]

    for i in 0..<dataPoints.count {
        let dataEntry = PieChartDataEntry(value: values[i], label: dataPoints[i])
        dataEntries.append(dataEntry)
    }

    let pieChartDataSet = PieChartDataSet(values: dataEntries, label: "")
    pieChartDataSet.colors = [UIColor(red: 17/255, green: 128/255, blue: 127/255, alpha: 1.0),UIColor(red: 47/255, green: 164/255, blue: 59/255, alpha: 1.0),UIColor.orange]
    let pieChartData = PieChartData(dataSet: pieChartDataSet)
    pieChartView.data = pieChartData
    pieChartView.centerText = "Amount Spent"
    pieChartView.chartDescription?.text = ""
    pieChartView.usePercentValuesEnabled = true
    pieChartView.legend.horizontalAlignment = .center

}

How to add "%" in PieChart data ? NSNumberFormatter() is no longer available

use valueFormatter! Please take a look at ChartsDemo first before asking, as it's all there!

    PieChartData *data = [[PieChartData alloc] initWithDataSet:dataSet];

    NSNumberFormatter *pFormatter = [[NSNumberFormatter alloc] init];
    pFormatter.numberStyle = NSNumberFormatterPercentStyle;
    pFormatter.maximumFractionDigits = 1;
    pFormatter.multiplier = @1.f;
    pFormatter.percentSymbol = @" %";
    [data setValueFormatter:[[ChartDefaultValueFormatter alloc] initWithFormatter:pFormatter]];
    [data setValueFont:[UIFont fontWithName:@"HelveticaNeue-Light" size:11.f]];
    [data setValueTextColor:UIColor.whiteColor];
