    self.frame = frame
    self.progressLayer = DottedCircleProgressLayer(progressConfig: progressConfigurator)
    DispatchQueue.main.async {
      self.layer.addSublayer(self.progressLayer)
    }
  }

  required public init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
  }
}
