When i draw a bezierPath in swift on UIView. I get straight line along with it. I only need the curved line is it possible to remove the straight line.

I can remove gray fill by: line.fillColor = UIColor.clear.cgColor

Not sure how i can remove the straight line

enter image description here

Code:

    let line = CAShapeLayer()
    let linePath = UIBezierPath()
    linePath.move(to: start)
    linePath.addLine(to: end)
    var dis = (end.x - start.x)/3.0
    linePath.addCurve(to: start,
                  controlPoint1: CGPoint(x: start.x + dis, y: start.y + dis),
                  controlPoint2: CGPoint(x: end.x - dis, y: end.y - dis))

    line.path = linePath.cgPath
    line.strokeColor = UIColor.red.cgColor
    //line.fillColor = UIColor.clear.cgColor
    line.lineWidth = 4.0
    line.opacity = 0.6
    self.view.layer.addSublayer(line)

Don't close the path. When you close a bezier path it adds a straight line between the beginning and ending of the path. If you don't close the path then it should not do that. (However you can't fill a non-closed path, just stroke it.)

If that doesn't help you, you'll need to edit your question to show your code that creates and draws your path.
