How can I draw bubble charts in swift project.

I spend too much time but I could not find any documents and example for bubble charts.

There is ob-c code but I converted to swift. Thanks.

func setChartBubble(dataPoints: [String], values1: [Double],values2: [Double],values3: [Double],sortIndex:Int) {

    var dataEntries1: [BubbleChartDataEntry] = []
    var dataEntries2: [BubbleChartDataEntry] = []
    var dataEntries3: [BubbleChartDataEntry] = []


    for i in 0..<dataPoints.count {

        let dataEntry = BubbleChartDataEntry(xIndex: i, value: values1[i], size: CGFloat(values1[i])*10)
        dataEntries1.append(dataEntry)
    }


    for i in 0..<dataPoints.count {

        let dataEntry = BubbleChartDataEntry(xIndex: i, value: values2[i], size: CGFloat(values2[i])*10)
        dataEntries2.append(dataEntry)
    }


    for i in 0..<dataPoints.count {

        let dataEntry = BubbleChartDataEntry(xIndex: i, value: values3[i], size: CGFloat(values3[i])*10)
        dataEntries3.append(dataEntry)
    }

    let chartData1 = BubbleChartDataSet(yVals: dataEntries1,label: "label1" )

    let chartData2 = BubbleChartDataSet(yVals: dataEntries2,label: "label2")

    let chartData3 = BubbleChartDataSet(yVals: dataEntries3,label: "label3")

    chartData1.colors =  [UIColor(red: 33/255, green: 150/255, blue: 254/255, alpha: 1)]
    chartData2.colors =  [UIColor(red: 62/255, green: 89/255, blue: 254/255, alpha: 1)]
    chartData3.colors =  [UIColor(red: 255/255, green: 70/255, blue: 48/255, alpha: 1)]

    let dataSets: [BubbleChartDataSet] = [chartData1,chartData2,chartData3]

    let data = BubbleChartData(xVals: dataPoints, dataSets: dataSets)

    bubbleChartView.data = data;
    bubbleChartView.descriptionText = ""
    bubbleChartView.animate(xAxisDuration: 2.0, yAxisDuration: 2.0, easingOption: .EaseInBounce)

}
