How to add Strings on Left Axis in iOS-charts?

[reza-khalafi]

Hello.
I want to set my custom array of String on left axis line.

let leftAxis = chartView.leftAxis
leftAxis.removeAllLimitLines()
leftAxis.gridLineDashLengths = [5, 5]
leftAxis.drawLimitLinesBehindDataEnabled = true
leftAxis.labelTextColor = .white
leftAxis.axisMinimum = 0
leftAxis.drawLabelsEnabled = true
let array = ["a","b","c","e","f","g","h"]
leftAxis.valueFormatter = IndexAxisValueFormatter(values: array)
leftAxis.granularity = 1

Not works.
