ios – Prohibit person contact occasions outdoors drawn bezierpath

I’ve created a view like this utilizing XIB with having half of top assign to that view.

static func drawRightTriangle(targetView goal: UIView, cornerRadius: CGFloat, borderView: UIView) {
        
        // Create a brand new path
        let path = UIBezierPath()
        
        // Triangle factors for proper aspect
        let high = CGPoint(x: goal.bounds.width - cornerRadius, y: cornerRadius)
        let backside = CGPoint(x: goal.bounds.width - cornerRadius, y: goal.bounds.top - cornerRadius)
        let left = CGPoint(x: cornerRadius, y: goal.bounds.top / 2)
        
        // Offset for easy curves
        let offset = cornerRadius / 2
        
        // Begin from high -> backside
        path.transfer(to: CGPoint(x: high.x, y: high.y + offset))
        path.addQuadCurve(to: CGPoint(x: backside.x, y: backside.y - offset),
                          controlPoint: high)
        
        // Backside -> left (center)
        path.addQuadCurve(to: CGPoint(x: left.x + offset, y: left.y),
                          controlPoint: backside)
        
        // Left -> again to high
        path.addQuadCurve(to: CGPoint(x: high.x, y: high.y + offset),
                          controlPoint: left)
        
        path.shut()
        
        // Model
        UIColor.darkGray.setStroke()
        path.lineWidth = 4
        path.lineJoinStyle = .spherical
        path.stroke()
        
        // Create a CAShapeLayer
        let shapeLayer = CAShapeLayer()
        shapeLayer.path = path.cgPath
        shapeLayer.place = CGPoint(x: 0, y: 0)
        goal.layer.masks = shapeLayer
        
        // 2. Add border layer (stroke solely)
        let borderLayer = CAShapeLayer()
        borderLayer.path = path.cgPath
        borderLayer.strokeColor = UIColor.white.cgColor
        borderLayer.fillColor = UIColor.clear.cgColor
        borderLayer.lineWidth = 0
        borderLayer.body = goal.bounds

        // 3. Add stroke layer as sublayer (not affected by masks)
        goal.layer.addSublayer(borderLayer)
    }

Above code is to attract triangle from up aspect down, which give me end result like under.

This picture has pan gesture added however it;s taking full view width and top. It is not contemplating drawn path on this view.

I wish to prohibit contact occasions outdoors that picture like under picture. I’ve the place it is taking full view width and top for that picture.

any assist could be appreciated.
