What did you do?

I'm try to archive annotation marker like swiftui charts RuleMark with annotation,
I tried with custom MarkerView with xib.

open class HistoryMarker: MarkerView {
    
    @IBOutlet weak var dateLable: UILabel!
    @IBOutlet weak var valueLabel: UILabel!
    
    var currentMonth: String = ""
    
    override open func awakeFromNib() {
        self.offset.x = -self.frame.size.width / 2.0
        self.offset.y = -self.frame.size.height - 7.0
    }
    open override func refreshContent(entry: ChartDataEntry, highlight: Highlight) {
        dateLable?.text = "\(Int(entry.x)) \(currentMonth)"
        valueLabel?.text = String.init(format: "%.1f", entry.y)
        layoutIfNeeded()
    }
}

let historyMarker: HistoryMarker = (HistoryMarker.viewFromXib() as? HistoryMarker)!
historyMarker.currentMonth = "Nov"
historyMarker.chartView = self
self.marker = historyMarker
