我一直在Swift / iOS中用highcharts绘制实时数据，现在的情况是：
我为从内部麦克风接收到的每一帧添加一个值到一个数组中。数组有一个固定的大小（它的工作原理类似于FIFO）。
现在我需要一个Highcharts线图来显示数组中的所有点，每次接收到新的音频帧时都会更新。我认为.redraw函数应该可以做到这一点。
下面是当前代码的样子：在Audioprocessing类中设置线图：

let options = HIOptions()
public var chartView = HIChartView(frame: CGRect(x: 0, y: 0, width: 1, height: 1))
let chart = HIChart()
let series = HISeries()

public func initChartView(view: UIView){
    // initialize Highcharts object
    chartView = HIChartView(frame: CGRect(x: view.bounds.origin.x, y: view.bounds.origin.y, width: view.bounds.size.width, height: (view.bounds.size.height - 50)))

    chart.type = "spline"
    options.chart = chart

    let title = HITitle()
    title.text = "Tonhoehe"
    options.title = title

    let xAxis = HIXAxis()
    xAxis.tickInterval = 1
    xAxis.type = "linear"
    xAxis.title = HITitle()
    xAxis.title.text = "Zeit [s]"
    options.xAxis = [xAxis]

    let yAxis = HIYAxis()
    yAxis.type = "logarithmic"
    yAxis.minorTickInterval = 0.1
    yAxis.title = HITitle()
    yAxis.title.text = "Frequenz [Hz]"
    options.yAxis = [yAxis]

    series.data = [1,2,3,4,5,4,3,2,1]
    series.showInLegend = false
    options.series = [series]

    chartView.options = options

}

在函数processData()中，我更新了Array（称为data），但无法更新Highcharts图：

...
// updating the array
data.append(maxFrequency ?? 0)
if(data.count >= 500){
     data.removeFirst()
}
let newSeries = HISeries()
        newSeries.data = data
        self.chartView.options.series = [newSeries]// this was recommended on github but does not work at all

这将成功编译，但当我运行程序时，它崩溃并出现以下错误：

我还尝试了.addPoint(HIDataPoint)和chartView.options.series[0].data = data，也没有工作。
TL;DR：我如何在Swift中访问与javascript中的.addPoint()方法相同的功能，以便将数据动态添加到Highcharts图表中？
https://github.com/highcharts/highcharts-ios/issues/116中提出的方法对我不起作用。
