As per your requirement Charts library already have that method in its delegate.

Please check below code :

1. Assign delegate to your ChartView like below

lineChartView.delegate = self

2. Implement Delegate method in your class

public func chartValueSelected(_ chartView: ChartViewBase, entry: ChartDataEntry, highlight: Highlight) {

}

Here you can write your code while user click on chart.
