Where does the CAShapeLayer do its drawing?

When a path is set, draw(in: ctx) still isn't called despite having output. I originally went down the path of subclassing CAShapeLayer but now I'm just confused how CALayer works.

Calayer.setNeedDisplay to call the draw function after initial drawing.

No, the issue is that the path is drawn -- without a call to draw(in: ctx). I'm just trying to figure where the drawing for a CAShapeLayer occurs. Is it done through some private magic?

It’s probably cashapelayer override func display() with the content updating like path.
