Why moveViewToX() won't move my display to the last value in my bar chart? - Swift

I'm new to Swift and I'm trying to create bar chart. I manage to create a chart but for some reason moveViewToX() does not work as expected - it does not scroll to the last x values. Here is my relevant function to create a chart:

func createBarView() {

       // Set basic parameters

        barChartView.xAxis.labelTextColor = .black
        barChartView.leftAxis.labelTextColor = .black
        barChartView.leftAxis.axisMinimum = 0
        barChartView.xAxis.labelPosition = XAxis.LabelPosition.bottom
        barChartView.xAxis.labelRotationAngle = 0
        barChartView.xAxis.granularity = 1
        barChartView.xAxis.labelFont = UIFont.systemFont(ofSize: 20.0, weight: .regular)
        barChartView.xAxis.drawGridLinesEnabled = false
        barChartView.rightAxis.drawGridLinesEnabled = false
        barChartView.leftAxis.drawGridLinesEnabled = false
        barChartView.rightAxis.enabled = false
        barChartView.leftAxis.enabled = false
        barChartView.xAxis.labelPosition = .bottom
        barChartView.clipsToBounds = true
        barChartView.layer.cornerRadius = 10
        barChartView.legend.enabled = false
        barChartView.animate(yAxisDuration: 1.3, easingOption: .easeInOutQuart)
        barChartView.scaleYEnabled = false
        barChartView.scaleXEnabled = false
        barChartView.pinchZoomEnabled = false
        barChartView.doubleTapToZoomEnabled = false

//Get X (days) and Y data (calories)

        let count = realm.objects(WorkoutData.self).count
        for i in 0 ..< count {
            let graphDates = realm.objects(WorkoutData.self)[i].date
            allDates.append(graphDates) 
            let calendarDate = Calendar.current.dateComponents([.day, .year, .month], from: graphDates)
            graphDays.append(String(calendarDate.day!)) // Get days array for xAxis

            
            let graphCalories = realm.objects(WorkoutData.self)[i].calories
            visosKalorijos.append(graphCalories) // Get calories array for yAxis
        }

//Supply data for BarChartDataEntry

        var entries = [BarChartDataEntry]()
        for i in 0 ..< count { // dataPoints
            let dataEntry = BarChartDataEntry(x: Double(i), y: Double(visosKalorijos[i]))

        entries.append(dataEntry) //// Get x:y data
        }

//Set labels of xAxis (to show days of the month)

        barChartView.xAxis.valueFormatter = IndexAxisValueFormatter(values: graphDays)

// Create dataset

        let set = BarChartDataSet(entries: entries, label: "-")

        set.colors = ChartColorTemplates.solid()
        set.valueFont = UIFont.systemFont(ofSize: 16)
        let data = BarChartData(dataSet: set)
        data.barWidth = Double(0.4)
        barChartView.data = data

// Set visibility

        barChartView.setVisibleXRangeMaximum(7)
        barChartView.moveViewToX(Double(count)) 

}

When function is executed I can see only up to 17th day, but there are more days on the xAxis if I scroll.

After view is loaded I need to scroll to the end.

The last part - // Set visibility is where the problem is - it does not scroll automatically to the last x value. What Am I doing wrong? Thanks for your help.
