Swift AppleMap MKOverlayRenderer Image Zoom In Bug

Question

Hi I need Help I do control Apple Map

I want overlay image on map

I use MKOverlayRenderer and this function override func draw(_ mapRect: MKMapRect, zoomScale: MKZoomScale, in context: CGContext)

and then success overlay

but map zoom level 2.0 over than image broken

if not use CGContext.rotate then image are not broken but use rotate then image are broken

class IndoorInfoOverlay: NSObject, MKOverlay {
    let coordinate: CLLocationCoordinate2D
    let boundingMapRect: MKMapRect

    init(indoorInfo: IndoorInfo) {
      boundingMapRect = indoorInfo.overlayBoundingMapRect
      coordinate = indoorInfo.midCoordinate
    }
}

class IndoorInfoOverlayView: MKOverlayRenderer {
  var overlayImage: UIImage
  var parent: IndoorMapView

  init(overlay: MKOverlay, overlayImage: UIImage,_ parent: IndoorMapView) {
      self.overlayImage = overlayImage
      self.parent = parent
      super.init(overlay: overlay)
  }

  override func draw(_ mapRect: MKMapRect, zoomScale: MKZoomScale, in context: CGContext) {
    guard let imageReference = overlayImage.cgImage else { return }
      let bearing = degreesToRadians(360 - (Double(self.parent.floorData!.FLOOR_BEARING) ?? 0))

      let rect = self.rect(for: overlay.boundingMapRect)
      context.scaleBy(x: 1.0, y: -1.0)
      context.translateBy(x: 0.0, y: -rect.size.height)
      if self.parent.floorData != nil {
          context.rotate(by: bearing)
      }
      context.draw(imageReference, in: rect, byTiling: false)
  }
                               
  private func degreesToRadians(_ x:Double) -> Double {
    return (Double.pi * x / 180.0)
  }
}
