I need to put dates from an array on xAxis

[mpapado3]

I am trying to understand how I can use an array populated with dates on the xAxis, but I haven't figured it out yet.

Below is my code for the setChart function. On the last row I use the dataPoints provided on the function bt they cannot be casted as IAxisValueFormatter.
If I remove this line the app works but returns the bar chart with 0 - 6 enumeration based on the for clause.

func setChart(dataPoints: [String], values: [Int]) {
        barChartView.noDataText = "You need to run some tests first to use the charts"
        
        var dataEntries: [BarChartDataEntry] = []
        
        for i in 0..<dataPoints.count {
            let dataEntry = BarChartDataEntry(x: Double(i), y: Double(values[i]))
            dataEntries.append(dataEntry)
        }
        
        let chartDataSet = BarChartDataSet(values: dataEntries, label: "Hyper")
        let chartData = BarChartData(dataSet: chartDataSet)
        let xAxis = barChartView.xAxis
        xAxis.labelWidth = 5
        barChartView.data = chartData
        barChartView.xAxis.labelPosition = .bottom
        barChartView.chartDescription?.text = "Hyper Diagram"
        barChartView.animate(xAxisDuration: 2.0, yAxisDuration: 2.0)
        barChartView.xAxis.valueFormatter = dataPoints as! IAxisValueFormatter  //This returns error
 
    }

Thank you!
