iOS Charts remove decimal from yValues

How to remove decimals from y values in iOS Charts? Im using the latest iOS Charts release with Swift3

Thanks for every one who tried to help, here was the fix, adding the below code

    let formatter = NumberFormatter()
    formatter.numberStyle = .none
    formatter.maximumFractionDigits = 0
    formatter.multiplier = 1.0
    chartData.valueFormatter = DefaultValueFormatter(formatter: formatter)

to the setBarChartData func

func setBarChartData(xValues: [String], yValues: [Double], label: String) {

    var dataEntries: [BarChartDataEntry] = []

    for i in 0..<yValues.count {
        let dataEntry = BarChartDataEntry(x: Double(i), y: yValues[i])
        dataEntries.append(dataEntry)
    }

    let chartDataSet = BarChartDataSet(values: dataEntries, label: label)
    let chartData = BarChartData(dataSet: chartDataSet)


    let formatter = NumberFormatter()
    formatter.numberStyle = .none
    formatter.maximumFractionDigits = 0
    formatter.multiplier = 1.0
    chartData.valueFormatter = DefaultValueFormatter(formatter: formatter)

    let chartFormatter = BarChartFormatter(labels: xValues)
    let xAxis = XAxis()
    xAxis.valueFormatter = chartFormatter
    self.xAxis.valueFormatter = xAxis.valueFormatter

    self.data = chartData
}
