Why draw(_ rect: CGRect) not called from custom view, then transitioning to code based UI?

Hello, I am moving from storyboards(I actually liked them) to the code based UI. So far it was great. The problem is that I can’t solve this issue. We have a custom view, which was previously included to storyboard and we only needed to call

view.setNeedsDisplay() and it worked… Right now it does not work with code, here is customView:

class View: UIView {
    var ratio :CGFloat = 125/86
    override func draw(_ rect: CGRect) {
        
        self.layer.sublayers?.removeAll()
        UIRectFill(rect)
        
        let ctx: CGContext = UIGraphicsGetCurrentContext()! //why it is null?
        ctx.setBlendMode(CGBlendMode.destinationOut)
        
        let shapeLayer = CAShapeLayer()
        shapeLayer.path = contourPath.cgPath
        shapeLayer.fillColor = UIColor.clear.cgColor
        shapeLayer.strokeColor = strokeColor.cgColor
        shapeLayer.lineWidth = 1.5
        self.layer.addSublayer(shapeLayer)
        
    }
    
    
}

I create it like this:

 var rectangleView: View = {
    let view = View(frame: .zero)
        view.translatesAutoresizingMaskIntoConstraints = false
        return view
    }()

And then add it like this:

view.addSubview(view)

view.setNeedsDisplay()

I tried in both viewDidLayoutSubviews and viewDidLoad, but it still did not appeared!If called manually view.draw and pass any CGRect I get that UIGraphicsGetCurrentContext() is null and application crashes… This so frustrating and I don’t know how should I change my customView or what should I do?

@wellbranding Do you still have issues with this?
