I have extension extension
```
BarChartView {
private class BarChartFormatter: NSObject,IAxisValueFormatter {
var values : [String]
required init (values : [String]) {
self.values = values
super.init()
}
func stringForValue(_ value: Double, axis: AxisBase?) -> String {
return values[Int(value)]
}
}
func setChartValues (xAxisValues : [String] , values : [Double],label : String) {
var barChartDataEntries = [BarChartDataEntry]()
for i in 0..<values.count {
let dataEntry = BarChartDataEntry(x: Double(i), y: values[i])
barChartDataEntries.append(dataEntry)
}
let chartDataSet = BarChartDataSet(values: barChartDataEntries, label: label)
chartDataSet.colors = ChartColorTemplates.colorful()
let chartData = BarChartData(dataSet: chartDataSet)
let formatter = BarChartFormatter(values: xAxisValues)
let xAxis = XAxis()
xAxis.valueFormatter = formatter
self.xAxis.valueFormatter = xAxis.valueFormatter
self.xAxis.labelPosition = .bottom
self.data = chartData
// self.data?.notifyDataChanged()
// self.notifyDataSetChanged()
self.animate(xAxisDuration: 2.0, yAxisDuration: 2.0, easingOption: .easeInBack) // Cause crash
}
}
```
And app crashes here
for j in 0 ..< Int(ceil(Double(dataSet.entryCount) * animator.phaseX)) // Crash here
{
guard let e = dataSet.entryForIndex(j) as? BarChartDataEntry else { continue }
Fatal error: Can't form Range with upperBound < lowerBound
(lldb) po dataSet.entryCount
12
(lldb) po animator.phaseX

Please solve this issue
I think it is possible that in your project there is a big function that takes time
the time is over
la solution
DispatchQueue.main.async(execute: {() -> Void in
self.animate(xAxisDuration: 2.0, yAxisDuration: 2.0, easingOption: .easeInBack)
})
I think so,
for j in 0 ..< Int(ceil(Double(dataSet.entryCount) * animator.phaseX))
change for
for j in stride(from: 0, to: Int(ceil(Double(dataSet.entryCount) * animator.phaseX)), by: 1)
@PrashantKT I have the same issue and the snippet that @txoan have posted is working, but it would be great if anyone can check if the solution doesn't introduce new bugs or any other problem. @jjatie @liuxuan30
