Get End CGPoint() of Arc

Question

I am creating arc with below line

func drawSomething(_ context: CGContext, rect: CGRect) {
    context.saveGState()
    let path = UIBezierPath()

    let pathStartRagAngle = (0).degreesToRadians
    let pathEndRagAngle = (220).degreesToRadians

    path.addArc(withCenter: centerS, radius: rangeLabelsRect.size.width / 2.0, startAngle: CGFloat(pathStartRagAngle), endAngle: CGFloat(pathEndRagAngle - 0.01), clockwise: true)
    let color =  UIColor.red
    color.setStroke()
    path.lineWidth = rangeLabelsWidth
    path.stroke()
}

Gave this result

what I wanted to do is add circle to end of red arc, for that I need CGPoint. so could find any way to do it,

you question is little bit not clear, will you need degree conversion from user touched CGPoint ? — Ammaiappan, Oct 05 '17 at 07:51

UIBezierPath has a currentPoint property which will be at the end of the last component you added to the path. That should work for you.
