Create horizontal bar chart with scpecific data - swift

Question

I'm learning how to create charts and I'm at the point where I need to use more complex data. I created charts where the usual ranges were used.
This is what my chart looks like now
What I need to end up with.
I don't know how to change the axes data according to the array:
items = [AgeItem(ageGroup: ">60", iqLevel: 95),
AgeItem(ageGroup: "45-60", iqLevel: 118),
AgeItem(ageGroup: "35-44", iqLevel: 141),
AgeItem(ageGroup: "25-34", iqLevel: 106),
AgeItem(ageGroup: "18-24", iqLevel: 126),
AgeItem(ageGroup: "16-17", iqLevel: 100)]
The task is to create a graph that will display how many points a person from a certain age group scored when passing the test. Y-axis - age group, X-axis - test points. I also need to add a "you" chart bar that will stand out from the others.
Here is my graph code:
override func awakeFromNib() {
super.awakeFromNib()
self.setup(barLineChartView: chartView)
chartView.delegate = self
chartView.drawBarShadowEnabled = false
chartView.drawValueAboveBarEnabled = true
chartView.maxVisibleCount = 60
let xAxis = chartView.xAxis
xAxis.labelPosition = .bottom
xAxis.labelFont = .systemFont(ofSize: 10)
xAxis.drawAxisLineEnabled = true
xAxis.granularity = 10
xAxis.labelTextColor = .white
let leftAxis = chartView.leftAxis
leftAxis.labelFont = .systemFont(ofSize: 10)
leftAxis.drawAxisLineEnabled = true
leftAxis.drawGridLinesEnabled = true
leftAxis.axisMinimum = 0
leftAxis.labelTextColor = .white
let rightAxis = chartView.rightAxis
rightAxis.enabled = true
rightAxis.labelFont = .systemFont(ofSize: 10)
rightAxis.drawAxisLineEnabled = true
rightAxis.axisMinimum = 0
rightAxis.labelTextColor = .white
chartView.fitBars = true
chartView.animate(yAxisDuration: 2.5)
self.setDataCount(Int(12) + 1, range: UInt32(190))
}
func setDataCount(_ count: Int, range: UInt32) {
let barWidth = 9.0
let spaceForBar = 10.0
let yVals = (0..<count).map { (i) -> BarChartDataEntry in
let mult = range + 1
let val = Double(arc4random_uniform(mult))
return BarChartDataEntry(x: Double(i)*spaceForBar, y: val)
}
let set1 = BarChartDataSet(entries: yVals)
set1.drawIconsEnabled = false
let data = BarChartData(dataSet: set1)
data.setValueFont(UIFont.poppins(size: 12))
data.barWidth = barWidth
data.setValueTextColor(.white)
chartView.data = data
}
func setup(barLineChartView chartView: BarLineChartViewBase) {
chartView.chartDescription.enabled = false
chartView.dragEnabled = true
chartView.setScaleEnabled(true)
chartView.pinchZoomEnabled = false
// ChartYAxis *leftAxis = chartView.leftAxis;
let xAxis = chartView.xAxis
xAxis.labelPosition = .bottom
chartView.rightAxis.enabled = false
}
